Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

Random idea: USL, but for Bitcoin addresses

This is my rough idea for a Bitcoin change that would allow for a bit more fraud protection. I might write up a BIP later if I get around to actually nailing it down.
For those unaware, the Universal Scammer List (USL) is a page dedicated to keeping track of the usernames of scammers on Reddit. Basically, if you want to conduct a transaction with someone on Reddit, you should first check if they're listed as a known scammer.
My idea is to do the same with Bitcoin addresses. A decentralised database of blacklisted addresses would be kept by anyone running a full node. Any funds in the blacklisted addresses are deemed worthless.
For example, address A gets listed for hacking into an exchange and stealing coins. Any funds held by address A would be deemed worthless. If they send 10 BTC to address B, then the network would remember that address B has 10 BTC that is worthless. If address B originally had 5 BTC and was sent 10 BTC by address A, they would have 15 BTC, but the bottom 10 BTC would be deemed worthless. If address B sends 2 BTC to address C, then C receives 2 good BTC and B is left with 3 good BTC and 10 blacklisted BTC, but if B sends another 4 BTC to address D, then D would receive 3 good BTC and 1 worthless BTC, and the network would now remember that D has 1 worthless Bitcoin. Therefore, before accepting the transaction as payment for something, they would have to check to make sure that they are not receiving worthless blacklisted coins.
Miners could also choose to selectively refuse to mine transactions involving blacklisted BTC because any miners' fees collected from such a transaction would be blacklisted as well. This could mean someone trying to send blacklisted BTC is essentially broadcasting a transaction with a 0 sat/byte fee rate, meaning their transaction would probably be stuck in the Mempool for quite a long time, if not forever if miners refuse to mine it.
Whenever someone wants an address blacklisted, they would announce it to the public via any mechanism, and anyone keeping a full node can decide whether or not to blacklist the address. Therefore, anyone who disagrees with the blacklisting is free to accept the coins at face value or mine them into a block. If you don't agree with the evidence presented, then you are free to not blacklist them. Therefore, contested coins would only be accepted as valid payment by those who think the coins should have never been blacklisted in the first place.
This system would not be meant to help every single person who gets scammed with Bitcoin, but it would discourage large scale wholesale Bitcoin fraud. It would be ridiculous to expect all full-node maintainers to become arbitrators of all disputes, and consensus would never be reached on half of the transactions being processed. Node operators would also ideally not have to remember as many transactions involving blacklisted coins because miners would refuse to mine them (transaction fees collected would be in blacklisted coins), meaning they'd be stuck in the Mempool for long periods of time, reducing the speed at which they can be moved around, if at all. So the ledger of blacklisted coins would not have to be updated extremely often. Blacklisting would only happen for really big scams involving tens or hundreds of Bitcoin, like if an exchange got hacked or something.
Scams have effectively less than an hour to be discovered. 10 minutes for the deposit into the address in question, and more, depending on how many block confirmations something must have before others will accept it for transactions sell goods for it. Therefore, if a merchant requires 3 block confirmations, then they would give 40 minutes for the address to be blacklisted. If the buyer's address is blacklisted before the transaction to the merchant gets 3 block confirmations, the merchant would realise they've been sent blacklisted coins and not ship the goods. 40 minutes isn't a lot of time, but it's better than nothing.
This has the additional effect of encouraging people to wait for more confirmations. For low-value transactions, the risk is nominal because even if you were sent worthless coins, you're probably only out the price of a coffee. But if you're selling a house, you might want to wait for even more block confirmations.
Money sent around too much could be deemed "too late to blacklist" if there is a risk that it would result in too many innocent people's Bitcoin getting blacklisted.
This system doesn't refund the Bitcoin of victims, so poor security practices would still be punished by a loss of coins, but criminals would not be rewarded for their efforts either. The lack of reward (or the risk of a lack of reward) would hopefully make people less inclined to try and pull off the type of big scams that are giving Bitcoin a bad reputation!

The Mysterious Entity that Caused the Bitcoin Network fees to Jump 146% in May

The Mysterious Entity that Caused the Bitcoin Network fees to Jump 146% in May
May 25, 2020
SHARE0
Bitcoin price has yet again taken a dive to $8,800, recording a drop of 4%.
Meanwhile, Network Demand Score which is a metric incorporating network velocity, transaction value, fees, and miner’s rolling inventory, climbed to 6/6 following the bitcoin halving meaning the network is growing stronger which could also be a sign that “we’re in a longer-term bull market.”
Since March 12th, just before the massive sell-off, this score has remained above a 3/6 reflecting growing strength in network activity and instilling confidence in the ongoing uptrend for the bitcoin price.
3 Reasons why fees skyrocketed
One component of this indicator, bitcoin on-chain fees has been surging like crazy.
Last week, Bitcoin average transaction fee climbed to $7, last seen in February 2018. This has the miner revenues from fees rising to the levels not seen for more than 2 years. But this week, it also dropped 55% to $3.13.
The increase in transaction fees, which is increasingly becoming more important for Bitcoin network security, has been because of the unconfirmed transactions piling on in mempool.
A decline in hash rate following halving caused fewer blocks to be found and will continue until the next difficulty adjustment has been one of the reasons behind this jump in fees.
The other reason is the large fluctuations in bitcoin price which has traders sending coins between exchanges.
Ather reason is a “mysterious entity which has been consolidating outputs at the highest fee rates, driving up fees for everyone,” pointed out Serrrgej Kotliar, CEO Bitrefill.
Who is this “Crazy1o1”?
Over the weekend Kotliar shared how, for the past 14 days, this mysterious entity has consolidated a lower-bound of 720 thousand outputs, 5 MB per day, more than BitMEX.
Since May 1st, this entity named “Crazy1o1” has spent around 804k UTXOs and has paid more than 104BTC in mining fees during this time, noted Laurent.
“On some days, these fees are equivalent to 10-12% of all the fees received by miners,” he said.
Laurent along with others suspect this entity to be the cryptocurrency exchange Coinbase.
Earlier this month, it was also found that crypto derivatives exchange BitMEX is making the bitcoin network expensive for everyone and its own users are paying 6.8% of total daily transaction fees.
Prepare for the next bull market
All of this a “decent fire drill for what might happen if we see another bull market,” said Kotliar. Grubles from Blockstream said,
“ON-CHAIN FEES AND BTC PRICE MOVEMENTS CHART. YOU CAN SEE THAT BIG MOVEMENTS RESULT IN PEOPLE RUSHING TO TRANSACT (ALMOST CERTAINLY TO/FROM EXCHANGES), PUSHING FEES UP FOR OTHER NON-TRADER USERS WHO NEED UNCENSORABLE / IRREVERSIBLE TRANSACTIONS.”
The fees reached its all-time high at over $55 during the peak of the bull market in December 2017. As such in the next bull market, a 5x growth in on-chain transactions should be expected.
But given that batching, one of the many ways the network has been scaled is here, it will prevent the pressure on the network from getting worse than 2017. But exchanges will need to be prepared for this.

Looking for Technical Information about Mining Pools

I'm doing research on how exactly bitcoins are mined, and I'm looking for detailed information about how mining pools work - i.e. what exactly is the pool server telling each participating miner to do.
It's so far my understanding that, when Bitcoins are mined, the following steps take place:
  1. Transactions from the mempool are selected for a new block; this may or may not be all the transactions in said mempool. A coinable transaction - which consists of the miner's wallet's address and other arbitrary data - that will help create new Bitcoin will also be added to the new block.
  2. All of said transactions are hashed together into a Merkle Root. The hashing algorithm is Double SHA-256.
  3. A block header is formed for the new block. Said block header consists of a Version, the Block Hash of the Previous Block in the Blockchain, said Merkle Root from earlier, a timestamp in UTC, the target, and a nonce - which is 32 bits long and can be any value from 0x00000000 to 0xFFFFFFFF (a total of 4,294,967,296 nonce values in total).
  4. The nonce value is set to 0x00000000, and said block header is double hashed to get the Block Hash of the current block; and if said Block Hash starts with a certain number of zeroes (depending on the difficulty), the miner sends the block to the Bitcoin Network, the block successfully added to the blockchain and the miner is awarded with newly created bitcoin.
  5. But if said Block Hash does not start with the required number of zeroes, said block will not be accepted by the network, and the miner Double Hashes the block again, but with a different nonce value; but if none of the 4,294,967,296 nonce values yields a Block Hash with the required number of zeroes, it will be impossible to add the block to the network - and in that case, the miner will either need to change the timestamp and try all 4,294,967,296 nonce values again, or the miner will need to start all over again and compose a new block with a different set of transactions (either a different coinable transaction, a different set of transactions from the mempool, or both).
Now, what I'm trying to figure out is what exactly each miner is doing differently in a mining pool, and if it is different depending on the pool.
One thing I've read is that a mining pool gives each participating miner a different set of transactions from the mempool.
I've also read that, because the most sophisticated miners can try all 4,294,967,296 nonce values in less than a fraction of a second, and since the timestamp can only be updated every second, the coinbase transaction is used as a "second nonce" (although, it is my understanding that, being part of a transaction, if this "extra nonce" is changed, all the transactions need to be double hashed into a new Merkle Root); and I may have read someplace that miners could also be given the same set of transactions from the mempool, but are each told to use a different set of "extra nonce" values for the coinbase transaction.
Is there anything else that pools tell miners to do differently? Is each pool different in the instructions it gives to the participating miners? Did I get anything wrong?
I want to make sure I have a full technical understanding of what mining pools are doing to mine bitcoin.

PREDICTION: 1BTC > $50K USD by ~ Q4 2020.

The fiat banking system is falling apart. The USD is going to hyperinflate. There will be cascading global credit and currency crises.
Amidst the chaos, there will be a rapid flight to hard money. We are nearing the tipping point.
I'm calling it here: 1BTC will be > $50,000 USD by ~ Q4 2020. Come back and laugh at me if I'm right or wrong.
But you've got to admit: we are at the breaking point. This is precisely the kind of chaos Satoshi predicted. Coronavirus is just the lit match to the gasoline-soaked ad-infinitum piles of fiat.

*Note: This is NOT financial advice. Just a prediction from a random Internet Stranger. Do you own research. Stack Sats. Review your OpSEC. Get a HW Wallet.

EDIT: Yes. I am still stacking sats. I am still trading USD for BTC. Even when there is blood in the streets. Even when it is my own.

Unable to move claimed BSV from ElectrumSV wallet (imported privkey)

Hi All,
First post on Reddit, but a long time reader and a bitcoin novice, despite having coins since ~2014!
I finally got around to claiming my BSV from my BCH. At the time of the fork I know what my balance of BCH was and therefore what I expect my BSV to be (1:1).
I can see this value in my ElectrumSV wallet after importing my private key for my BCH address. My BCH wallet is BitCoinABC and is fully in sync. However, when I try and send and BSV from my ElectrumSV wallet to a recipient, I get the 'Conflicts with one already in the server's mempool' error (\n\n258: txn-mempool-conflict).
I should say that I initially claimed these coins approx. 30 hours ago now and have successfully exchanged a small amount of BCH to BSV and sent it to the wallet that has the claimed coins in it. The small transfer is now also stuck in that wallet.
Research tells me I probably need to make a raw transaction to create a double spend, but this is beyond my current ability... either that or wait for the block height to catch up, which I would have thought may have have happened by now, looking at the block height differences between BCH & BSV?
So any help or pointers would be appreciated...
TIA


++EDIT++
Thanks to Deminero30 this has been resolved and the BSV recovered to a functional address!

Commissions in the Bitcoin network fell by 78% after halving

The halving of the award on the Bitcoin network on May 11 led to a sharp increase of the commission - on May 20, the median value reached a record $3.95. Now the figure has dropped to $1.59, and the average commission level has fallen by 66% to $2.25.
The median value does not include data that stand out strongly from the overall picture, and the average takes into account all figures. A decrease in the commission was facilitated by a decrease in the bitcoin mempool: on May 21, the total size of unconfirmed transfers reached 94 Mb, and by the end of the month, the volume of the mempool fell by 99% to 250 Kb.

I wrote an answer to this article regarding the IFP

https://read.cash/@SeanBallard/the-simplest-reason-against-the-ifp-77cf8e9e
My answer is not "for or against the IFP"-type, BUT an answer to the "legitimate value proposition" of what funds for dev team like ABC actually is neccessary for.
I paste my answer here as well:
"through a legitimate value proposition"
Let me pitch on what value proposition the node development teams offer:
  1. Maintenance/vigilance ie. if a new attack vector against the network is found, they go in and provide a fix quickly ie. they always have one or two devs on alert. This is what e.g. ABC has been doing since the beginning of BCH.
  2. They develop the next needed upgrade features for the network - everything from single features such as a specific smart contract OP code to meet an immidiate demand in the market to more complicated upgrades/rewrites such as a much needed rewrite of the mempool acceptance code (*).
  3. They make research into areas that need more exploring before deciding on a solution. For example - everybody agrees that 0-conf needs improvement to be able to serve fast casual payment with high security, but nobody is absolutely sure what approach is the best, yet. Avalanche (/Snowglobe) is just one proposal for a solution to improved 0-conf security.
(*): The rewrite of the mempool acceptance code will solve many things, such as "removing the max 25 chain tx limit" in a safe & scalable manner, better fee policies and general scalability such as much higher transaction throughout & faster validation. The price for this much needed rewriting of mempool acceptance code, besides the needed man-months to do it, is also that back-porting of improvements from Bitcoin Core is no longer applicable which means that BCH node development will have to carry the cost of maintanence to a much higher degree than before, going forward!

Liquid CAD: Canadian dollar payments on the Liquid Sidechain

Hello fellow Canadian bitcoiners or bitcoinca! You will find below all the information related to the launch of Liquid CAD and Bull Bitcoin's Liquid Bitcoin integration. I'll be checking comments here to answer your questions! I'm also posting some comments on my announcement tweet here: https://twitter.com/francispouliot\_/status/1245758698120605697?s=20

Making the Canadian Dollar Bleed Into Bitcoin

Building the infrastructure for the Bitcoin Standard in Canada before the collapse of fiat currencies is the critical mission objective that drives innovation at Bull Bitcoin.
We are very excited to announce an important milestone in fulfilling this duty: the public release of Liquid CAD, our newest product designed to accelerate and facilitate the adoption of Bitcoin.
Liquid CAD is a non-custodial prepaid payment system denominated in Canadian dollars. Units of Liquid CAD (L-CAD) consist of vouchers issued on the Liquid Network as confidential bearer assets that can be transacted peer-to-peer using a Liquid wallet.
Users acquire Liquid CAD by withdrawing their account balance out of Bull Bitcoin, by purchasing Liquid CAD with Bitcoin on Bull Bitcoin, by using the Liquid CAD withdrawal method on other Bitcoin liquidity providers such as Aquanow or by accepting L-CAD as method of payment.
L-CAD assets can only be redeemed for Bitcoin. They cannot be redeemed for a fiat currency payment.
Liquid CAD is a unique project rethinking the concept of fiat-pegged assets, avoiding the banking business model of “fiatcoin” (aka stablecoins) in favor of a prepaid payments model entirely centred around Bitcoin on-ramp and off-ramp. Liquid CAD is not a currency, nor is it a security: it is a prepaid card.
Importantly, the business model of Liquid CAD is not to collect interest on funds in our custody, unlike fiatcoins, but rather to drive the sales of Bitcoin from which we derive our revenue and we benefit from Liquid CAD assets being cashed out and thus removed from our balance sheet. Bull Bitcoin does not get any revenue from interest.
Every time an L-CAD token is purchased by a user, the amount of dollars deposited on Bull Bitcoin is guaranteed to one day be used by someone to purchase Bitcoin. It’s a one-way street: once a unit of fiat is tokenized as L-CAD, it’s never going back to its off-chain fiat form and will ultimately result in a buy order on a Bitcoin trading platform.
The Liquid CAD logo is a drop of blood because our objective is to accelerate “fiat bleed”, a phenomenon best described by Pierre Rochard in his magnificent essay Speculative Attack:
“Bitcoin will not be eagerly adopted by the mainstream, it will be forced upon them. Forced, as in “compelled by economic reality”. People will be forced to pay with bitcoins, not because of ‘the technology’, but because no one will accept their worthless fiat for payments. Contrary to popular belief, good money drives out bad. This “driving out” has started as a small fiat bleed. It will rapidly escalate into Class IV hemorrhaging due to speculative attacks on weak fiat currencies. The end result will be hyperbitcoinization, i.e. “your money is no good here. Bitcoins are not just good money, they are the best money. The Bitcoin network has the best monetary policy and the best brand. We should therefore expect that bitcoins will drive out bad, weak currencies. My own prediction is that slow bleed has been accelerating and is only the first step. The second step will be speculative attacks that use bitcoins as a platform. The third and final step will be hyperbitcoinization.”
Different representations of Canadian dollars compete to be used as payment methods (cash, bank balances, PayPal balances, closed-loop prepaid cards, open-loop prepaid cards, etc.) and that the winner will be the one that has the best Bitcoin saleability, i.e. which can be most easily sold for Bitcoin at a moment’s notice.
We’re very proud to provide this alternative payment method to Canadians in a time where the banking system is falling deeper into crisis, especially as the Canadian dollar is demonstrating itself to be one of the most pointless and weakest currencies that nobody really wants to hold.
Finally, we’re very happy to be partnering with Aquanow, our recommended institutional liquidity provider for high-volume BTC-CAD trading. They will accept Liquid CAD deposits and withdrawals as being interchangeable with Canadian dollars. We hope that Liquid CAD will become the standard representation of Canadian dollar value among Canadian Bitcoin users.

Liquid Bitcoin (L-BTC) integration

In addition to Liquid CAD, Bull Bitcoin is also announcing that Liquid Bitcoin (L-BTC) payments are now supported interchangeably with Bitcoin transactions for all Bull Bitcoin services. This means that our users can buy, sell and spend L-BTC instead of BTC.
Canadian Bitcoin traders can purchase L-BTC from BullBitcoin.com and fund their international trading accounts with L-BTC using ultra fast and cheap confidential transactions. They can also cash-out their Bitcoin balance as L-BTC from these platforms and sell those L-BTC for fiat on Bylls.com, avoiding risky and expensive international wire transfers to unknown and untrusted foreign banks.
The transactional benefits of L-BTC are very potent:
Disclaimer: Liquid Bitcoin (L-BTC) is not the same as Bitcoin (BTC). L-BTC Liquid Network assets are IOUs for Bitcoin held in a multisignature contract by the Liquid Network federation. The custody of the underlying Bitcoin is managed by a decentralized network of 15 members which process transactions and withdrawals from the multisignature contract according to the Liquid Federation protocol rules.

Liquid CAD detailed overview

Peer-to-peer prepaid payments by Bull Bitcoin

Liquid CAD is a non-custodial prepaid payment system denominated in Canadian dollars. Units of Liquid CAD (L-CAD) consist of vouchers issued on the Liquid Network as confidential bearer assets that can be transacted peer-to-peer using a Liquid wallet. Users acquire Liquid CAD by withdrawing their account balance out of the Bull Bitcoin, by purchasing Liquid CAD with Bitcoin on Bull Bitcoin, by using the Liquid CAD withdrawal method on other Bitcoin liquidity providers such as Aquanow or by accepting L-CAD as method of payment.

A new payment method in Canada

Liquid CAD can be used by anyone to send and receive payments denominated in Canadian dollars. Because of the permissionless nature of the Liquid Network, Bull Bitcoin cannot prevent Liquid CAD from being traded on secondary markets. Merchants, individuals and institutions must accept that only Bull Bitcoin can guarantee redemption of the L-CAD and that this redemption will be exclusively paid out in Bitcoin. Accepting Liquid CAD as payment is, in effect, the same as accepting gift cards as payment. However, Bitcoin being the most liquid commodity on the market, it can be transformed into any other currency easily for example using services such a Bylls which allow Canadians to pay all their utility bills, send bank transfers to third parties or sell Bitcoin to their bank account.

Making Canadian dollars bleed into Bitcoin

The purpose of Liquid CAD is to facilitate the transfer fiat in the context of the purchase and sale of Bitcoin and providing innovative new services that help Bitcoin users hedge the value of Canadian dollars against Bitcoin in the context of their commercial transactions. Our goal is to create a payment method that is specifically targeting Bitcoin users that wish to liquidate Canadian dollar payments for Bitcoin. Our mission is to accelerate the phenomenon known as “fiat bleed” whereby Canadians will gradually abandon inferior money (such as the Canadian dollar) for the superior Bitcoin alternative. Every Liquid CAD issued will ultimately be exchanged into Bitcoin. We are excited for the day Liquid CAD will be made obsolete by the inevitable hyperbitcoinization of the Canadian economy.

Regulation: is Liquid CAD a stablecoin?

Liquid CAD is not a general-purpose “stablecoin”. It is a closed-loop Bitcoin prepaid card. It can exclusively be redeemed for Bitcoin on the Bull Bitcoin platform (or at affiliated merchants). Bull Bitcoin is the only counterparty, and it cannot be redeemed for a canadian dollar payment. It is substantively the same as Canadian Tire money. Unlike stablecoins, Bull Bitcoin makes money with L-CAD by driving the sales of Bitcoin on its platform, and doesn’t collect interest on the deposits of Liquid CAD users.
The purchase of Liquid CAD with Canadian dollars is regulated in the Province of Quebec as a prepaid card under the Consumer Protection Act and the Regulation respecting the application of the Consumer Protection Act Consumer Protection Act which define a prepaid card as “a certificate, card or other medium of exchange that is paid in advance and allows the consumer to acquire goods or services from one or more merchants”.
The purchase of Bitcoin using Liquid CAD is regulated in Canada by the Financial Transactions and Reports Analysis Centre of Canada under the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (S.C. 2000, c. 17).

Counterparty risk

Like all other closed-loop prepaid instruments, Liquid CAD has counterparty risk. The owners are trusting that they will eventually be able to use Liquid CAD as a payment method on the Bull Bitcoin platform to fund their account and purchase Bitcoin. When a Bull Bitcoin user withdraws his Bull Bitcoin account balance as an L-CAD token, the Canadian dollars he used to fund this balance remains in our possession in the same manner as regular Bull Bitcoin vouchers. These funds are used to execute Bitcoin purchases when L-CAD owners decide to redeem their L-CAD for Bitcoin. In essence, each L-CAD is “backed” by the Canadian dollar deposit of the user that withdraws it from the platform in the first place.

Benefits of using and accepting Liquid CAD for payments

Irreversible, non-custodial and no bank required

Liquid CAD payments cannot be charged back, cancelled, delayed or frozen. There is no intermediary between the sender and the recipient. It is a bearer asset: whoever owns the keys owns the coins. It is a perfect way to accept payments or transact securely without depending on banks and payment processors. Canadians can use Liquid CAD to purchase Bitcoin and then use Bylls.com to pay billers, personal payees or simply sell Bitcoin to their bank account.

Fast transaction and cheap fees

Liquid Network transactions are sent and received instantly and require 1 minute for settlement. Transaction fees paid using Liquid Bitcoin can be as low as 300 satoshis per transaction (a few cents). In order to benefit from these cheap fees, make sure to download the latest version of the Elements software and ensure that the minimum transaction fee is set at 100 satoshis per kilobye. It only takes a few minutes to set up a free Liquid Network wallet, such a Green Wallet by blockstream.

Confidential transactions

Unlike Bitcoin, transactions between the sender and the recipient are encrypted. It is impossible for third parties observing Liquid CAD transactions on a block explorer to determine the amount of the transaction. In addition, it’s also impossible to even know you are using Liquid CAD, since the data identifying the asset itself is also encrypted!

What are the use-cases of Liquid CAD?

Buying and selling Bitcoin

The primary use-case of Liquid CAD is to make it easier to buy and sell Bitcoin on the Bull Bitcoin platform. By withdrawing their balance from Bull Bitcoin, users are reducing some (but not all) of the custody risk associated with keeping fiat currency on an exchange. For example, use Liquid CAD to create your own non-custodial dollar-cost-averaging schedule!

Onboarding new Bitcoin users

New users can be overwhelmed by the experience of dealing with banks to buy Bitcoin (and the heavier KYC process of account funding). You may be tempted to buy Bitcoin for them, but that will impose a lot of burdens on you. It’s much easier to set them up with a Green wallet, send them Liquid CAD and show them how to use Bull Bitcoin! They decide when is the right time for them to invest, with a lower KYC burden.

Hedging Bitcoin price

You may believe the price of Bitcoin will go down in the short term, but you still want to hold Bitcoin in the long term. Normally you have two options: short the Bitcoin price (very risky!) or sell your Bitcoin and receive Canadian dollars in your bank account (inconvenient!). By selling your Bitcoin for Liquid CAD, you can lock in the value of Bitcoin right now and buy them back later without needing to use your bank account or taking risks with leverage.

Accepting payments

As a merchant, you want to receive the settlement of payments in Bitcoin. But this imposes a burden on your customers, which have to deal with the Bitcoin price volatility when they are paying you. Ask your clients to pay you with Liquid CAD, and you can get the settlement with Bitcoin on your own terms.

Payroll and suppliers

What if your staff or suppliers want to get paid in Bitcoin? It can be very difficult, because this means you are effectively buying Bitcoin on their behalf. Instead, you can pay them in Liquid CAD and let them deal with the process of choosing the exchange rate and using their own wallet. Let them deal with the tax burden, exchange rates and Bitcoin wallet security.

Withdraw account balance as L-CAD

This is conceptually the same as “buying” Liquid CAD with your account balance. We call it “Withdrawing L-CAD” because on the Bull Bitcoin platform, we consider L-CAD and CAD to be interchangeable and fungible.

Fund account balance with L-CAD

To redeem Liquid CAD for Bitcoin, users need to first fund their account by selecting the “Deposit L-CAD” payment method. Bull Bitcoin users must always fund their account first before buying Bitcoin, and then purchase Bitcoin with their account balances. Reminder: account balances cannot be withdraw as fiat payments, but can later be withdrawn again as L-CAD.

Sell Bitcoin for L-CAD

You can sell Bitcoin and receive Liquid CAD payments instead of a bill payment, personal payee payment or bank payment. As soon as the Bitcoin transaction is confirmed, the Liquid CAD transaction is sent to the address you provided.

Liquid Bitcoin (L-BTC) and Bitcoin interchangeability

For every service which involves a Bitcoin payment, the user can substitute traditional Bitcoin payments for Liquid Bitcoin payments. This includes:

Bitcoin transfer fees have risen to a two-year high

The bitcoin network still cannot return to normal after halving. On May 20, the average transaction fee level rose to $6.633, the highest level since June 2018. A month ago, before halving, the figure was 10 times lower.
The size of the mempool - the volume of unconfirmed transactions - increased to the values of the winter of 2018. On May 21, it was 94.41 Mb. Against this background, the cost of BTC dropped from $9,600 to $8,800. Now the average market price of bitcoin is $9,167, in 24 hrs the cryptocurrency has lost 2.10% in price.
On May 11, the block reward was halved in the Bitcoin network from 12.5 BTC to 6.25 BTC.

Market Analysis on May 20, 2020: Only Bitcoin breaks 10,000 points a recent bullish trend will form

Market Analysis on May 20, 2020: Only Bitcoin breaks 10,000 points a recent bullish trend will form
[Today's Hot Tips]
1. [BSV network test catches up with Bitcoin halving, resulting in transaction backlog and 309 MB large block innovation record]
On May 19, the BSV node team published a "Comment on the user stress test on the Bitcoin SV network on May 12", saying that some users launched a week-long public stress test on the Bitcoin SV network from May 12. On the first day of testing, about 2 million low-rate transactions were broadcast to the Bitcoin SV network. The rate of most of these transactions exceeds the default value of the forwarding rate, but is lower than the transaction acceptance rate. This means that these transactions can be propagated smoothly, but they will not be packaged by the vast majority of miners, which results in a continuous backlog of transactions and occupies up to 1.7GB of memory. At the same time, the backlog of transactions happened on the first day after the BTC block reward was halved. After the halving, many BTC miners transferred to BSV, which diluted the previous BSV miners' hashrate.
At the same time, the mining pool that implements the transaction acceptance rate of 0.25 Satoshi / byte (the default value of the forwarding rate), that is, Mempool has only mine less than 1% block of the area after May 11 due to the decline in the hashrate, it is not possible to process all the backlog of transactions on your own. Finally, on May 12, the backlog of transactions in the memory pool was cleared by TAAL, and a large 309MB block was mined out, setting a new record.
2. [Miao Wei, Minister of the Ministry of Industry and Information Technology: Strongly support blockchain and other technological innovations and industrial applications]
Miao wei, minister of the ministry of industry and information technology, said at a press conference held by the state council information office today that the development of new industries and new forms of business should be vigorously promoted.We will actively promote the new generation of information technology to support epidemic prevention and control and the resumption of work and production, and vigorously support technological innovation and industrial application in 5G, artificial intelligence, industrial Internet, Internet of things, Internet of vehicles, big data, and blockchain.
3. 【BTC reduced the difficulty by 6% at 10:06 today, this is the first adjustment after completing the halving】
According to the OKLink blockchain browser, Bitcoin's first difficulty adjustment was completed after halving the block height at 631008 at 10:06:56 Beijing time on May 20. The difficulty of the whole network is reduced by 6.00% to 15.14T compared with before halving, and the unit hashrate income is adjusted to 0.00008831 BTC / T, which is an increase from the previous half.
According to the introduction, OKLink blockchain browser is an information service application created by OKLink, the first blockchain big data listed company in the world. It aims to present fast, accurate and comprehensive data on the chain and provide users with professional and personalized data analysis services.
4. [The 25,000 BTC in the core cold wallet of Gate.io has not changed this year]
Regarding the recent security rumors of the Gate.io exchange, some investors should be inquired. Although the specific progress of the case is still unknown, as far as the current BTC asset status of the exchange is concerned, the Chainsmap monitoring system found that 25,100 BTC in its core cold wallet have not been transferred out this year. In addition, there are nearly 6,000 BTC in other official core wallets. At the same time, due to rumors, the exchange's recent net outflow of bitcoin has increased and reached its recent peak on Sunday, but then the net outflow data soon fell back.
[Today's market analysis]
Bitcoin (BTC)BTC continued to oscillate around 9670 USDT in the early morning. It rebounded slightly at about 6 o'clock in the morning and returned to above 9700 USDT in a short time. The highest rose to 9773.97 USDT. At present, BTC as a whole fluctuated in a narrow range around 9700 USDT. The mainstream currencies followed the consolidation, and all currencies were adjusted in shock. BTC is currently reported at 9760.4 USDT at LOEx Global, an increase of 0.77% in 24h.

Bitcoin is facing a change. In the past few hours, Bitcoin has been rising wildly. Its price quickly soared to $ 9,900, but BitMEX's internal problems paralyzed the platform and affected the cryptocurrency. After the incident, Bitcoin fell 3.5%, erasing today's gains. However, under the negative situation, Bitcoin is still in a stable and strong position, indicating that Bitcoin is here to refuse to fall, and the 10,000 points will definitely go up again. However, in the face of a downward trend line, it tends to go back down and then make an upward breakthrough. For the bulls, Bitcoin needs to break the $ 10,000 level to form a recent bullish trend.
Operation suggestions:
Support level: the first support level is 9500 points, the second support level is 9300 integers;
Resistance level: the first resistance level is 10000 points, the second resistance level is 11000 points.

Bitcoin Price Prediction 2020

Bitcoin Price Prediction 2020
Bitcoin is a digital and fully decentralized currency. Decentralization of the network is the main goal of the Bitcoin. The fundamental achievement of bitcoin is its genuine peer-to-peer payment system; no person or even institution was “in charge” of bitcoin.
by StealthEX
Three main ideas were embedded in the Bitcoin code:
• Bitcoin should not be regulated by anyone.
• Its emission should not be infinite.
• The cost of a coin depends on its demand.
The maximum number of bitcoins – 21 million, and the possibility of their extraction were laid in the bitcoin algorithm.
Bitcoin “halving” occurred on 11 May 2020. This means that its miners’ remuneration was halved.

Epic Cash Vitex Exchange AMA

What is EPIC CASH?
Epic Cash is the final point in the journey toward true P2P internet cash, the cornerstone of a private financial system. The Epic currency aims to become the world’s most effective privacy-protecting form of digital money. In order to fulfill that goal, it satisfies the three principal functions of money:
1. Store of Value — can be saved, retrieved, and exchanged at a later time, and of predictable value when retrieved;
2. Medium of Exchange — anything accepted as representing a standard of value and exchangeable for goods or services;
3. Unit of Account — the unit by which the value of a thing is accounted for and compared.

Oleg✌🏻
Hello community! Our AMA with EPIC begins🚀 We are very happy to have you here, on our joint AMA👌 So, lets start! The very first question for you. Can you introduce yourself?
Max Freeman | Epic Cash | Mimblewimble I’m Max Freeman, which stands for “Maximum Freedom for Mankind” — we believe that the existing fiat money system enslaves people by unfairly confiscating their wealth through inflation. By using an honest money system such as Epic, we can improve the quality of life for billions of people worldwide.
Yoga Dude Hello, I am Yoga Dude 🙂 I handle Marketing and PR, in crypto since 2011 started as Bitcoin miner, and in 2014 in Monero, and in 2015 in Ethereum, oh and briefly in DOGE for fun and unexpected profit. Heard about Epic Cash while learning about the Mimblewimble algo and joined the team last year.
JLong I am John, Doing the general engineering and managerial work
Max Freeman | Epic Cash | Mimblewimble I have been involved in early stage cryptos for the past 3 years, after building a global trading business for the past 20 years.
Oleg✌🏻 nice to meet you🙂
Max Freeman | Epic Cash | Mimblewimble Epic is a decentralized community project like Bitcoin or Monero, there is no central authority or corporation involved. We had no ICO and no premine, we had a fair launch at 0 supply last September.
Yoga Dude Great to meet everyone :)
Oleg✌🏻 Here we go the 1st question for you ~ 1. What is Epic Cash about?
Yoga Dude Epic Cash is designed to fulfill Satoshi’s original vision of P2P electronic cash, adjusting for what we learned from Bitcoin, a medium of exchange that is fast, free, open to all, while being private and fungible. We launched in September 2019 as a Proof of Work mineable crypto, without an ICO or a premine.
Oleg✌🏻 Look like a real Bitcoin🙂
Yoga Dude with privacy and fungibility 😄
Oleg✌🏻 Sounds cool! move on to the next question… 2. What makes Epic Cash better than Monero or other privacy coins?
Max Freeman | Epic Cash | Mimblewimble First off, we have a lot of respect for Monero and other privacy coins, we learned a lot from what they did right and what they did wrong, Our blockchain is much lighter than Monero or Bitcoin, our transaction engine is faster than Monero or ZCash. We use a three mining algo approach to allow more users the ability to obtain Epic Cash. We are a new, highly undervalued, coin and we look great not only for future use but for today's investment. Our blockchain is 90+% smaller than Monero or Bitcoin. Coins such as Zcash have optional privacy. Epic makes all transactions private, and it is impossible to trace movements of coins by watching wallet addresses.
Oleg✌🏻 Young and hot😋 security and privacy level is very important now but… 3. Why copy the same supply economics as Bitcoin?
Yoga Dude It is hard to compete with the success of Bitcoin today, part of the elegance and the appeal of Bitcoin is the responsible emission rate, terminating at 21million highly sub dividable coins. Like the Bitcoin supply curve, Epic Cash encourages early adopters, and with subsequent halvenings maintains a gradually diminishing flow of additional currency while preserving the overall value.
Max Freeman | Epic Cash | Mimblewimble In 2028, the supply of Epic matches that of Bitcoin and they stay in sync until the final coin is mined in 2140. We have 4 halvenings between now and then, which is demonstrated in Bitcoin to drive the value over market cycles. Epic is a chance for people who were late to Bitcoin to ride the wave and not miss their opportunity this time.
Oleg✌🏻 Interesting! 4. Why Choose Epic Cash over Grin and Beam?
Max Freeman | Epic Cash | Mimblewimble First of all, we have tremendous respect for all Mimblewimble currencies and their talented teams, they all taught us a lot and we are thankful for that. Without sounding too contentious, the choice seems obvious. We offer the same core tech, but with a much more responsible emission curve — Grin is an endless fountain of emission and inflation (60 per second forever), and Beam is even more frontloaded outpacing even Grin’s aggressive emission schedule for the next several years… We respect Grin and Beam, we learned from them, and we believe we are the next evolutionary step. Additionally, as we mentioned earlier, we offer more ways to mine Epic Cash, both with GPU and CPU and ASICs, this gives us more potential users and miners, vs Grin and Beam that are only mineable with GPUs.
Yoga Dude Yes, all that ☝️😄
Oleg✌🏻 I hope the miners read it all carefully 👌 Next question 5. Why have a development fund tax and what will it be used for?
Yoga Dude Dev fund tax today is at a reasonable 7.77% dropping by 1.11% every year until it hits zero. As Epic Cash grows in value these funds will become increasingly more relevant in additional technical, marketing, and fintech partnerships developments.
Oleg✌🏻 Very smart! 6. What is the advantage of 3 mining algorithms?
Max Freeman | Epic Cash | Mimblewimble By having multiple mining algorithms we are able to attract CPU, GPU, and ASIC miners simultaneously. Currently all other Mimblewimble currencies are mineable with GPU only ignoring a large segment of CPU miners. Monero made a splash migrating to the RandomX CPU mining algo. Epic Cash from the beginning embraces all mining communities. Many miners are successfully using older hardware such as Xeon processors to help secure the network. We use RandomX for CPU, ProgPow for GPU, and Cuckoo for ASIC.
Longer term, our flexible architecture means we can have many algorithms, not just 3. Our roadmap includes an allocation for SHA3 Keccak, which will help further decentralize the network and keep it unstoppable.
Yoga Dude We love miners 🙂 and Epic Cash can be mined with laptops and gaming rigs 🙂
Oleg✌🏻 A wide selection of mining methods is a great way to create a stable, decentralized and large network👌 Let’s talk about persons… 7. Who are the people developing Epic Cash?
Yoga Dude We are blessed with a very talented team of skilled developers with diverse backgrounds, many of them are volunteers who believe in what Epic Cash stands for and contribute with product and usability innovation. Our teams main focus is to make Epic Cash the best, most secure, most user friendly and usable product on the market, without making it unnecessarily techie, with as much mainstream user appeal as possible. This is a serious challenge but we are up for it 😄
Max Freeman | Epic Cash | Mimblewimble It is also important to note that we are a truly open ecosystem that anyone can participate in. Our community has developed wallets, mining pools, educational content, and much else besides. We are not limited by the funding generated during an ICO or VC investment, our users are an essential element of our team.
Oleg✌🏻 Sounds very attractive. 8. What do you think is currently lack in today’s crypto?
Max Freeman | Epic Cash | Mimblewimble We believe there is not enough privacy, anonymity and fungibility, although there is a growing awareness in the community as to why these are necessary. People are waking up to the fact that privacy is a right for everyone but today it is being exploited and violated by corporations, governments and unscrupulous individuals. Privacy does not mean that you have something to hide. We have doors on our houses, curtains on our windows, we wear clothes, and we have security on our bank accounts and businesses, not because we are criminals.
Fungibility (the property of not being able to distinguish one unit of currency from another) also has become a hot issue as people have started to get in trouble because of someone else’s misdeeds. Tainted money (coins that are blacklisted or restricted) is a problem for Bitcoin and Ethereum, the top two cryptos today. Mimblewimble eliminates the risk of tainted coins making them indistinguishable from each other. With traceable coins, you always have to worry if the coins you are getting were involved in a hack, or perhaps the darknet.
Oleg✌🏻 It’s good to see strong and safe coin in our time Let’s talk about your future… 9. What does the Epic Cash roadmap look like going forward?
Yoga Dude First and foremost, we are focused on security and usability.
We are working on a new, improved GUI wallet to incorporate the community feedback on ways to improve it.
We are in the process of completing final testing phases for the next iteration of Epic Cash which will make it more secure and stable. Once that is done, we will be rolling out Android and iOS support to make Epic Cash usable on leading smartphones and smartwatches. Beyond that without going into too much detail we are focused on continuous evolution of privacy, ease of mining, and overall speed and usability.
And of course we are constantly looking to add more exchanges both with and without KYC.
Oleg✌🏻 Are you working on Android and IOS wallet ? What will your application be?
Max Freeman | Epic Cash | Mimblewimble Yes, we will release a mobile wallet this year. It will bring us one step closer to people being able to actually use cryptocurrency as money in daily life.
Yoga Dude The idea is to be able to access Epic Cash from any platform and device
Max Freeman | Epic Cash | Mimblewimble Epic is very lightweight, which means that low-end devices such as smartwatches can participate.
Oleg✌🏻 Ok, got it. Thanks for clarification! 10. What else can you tell us about Epic Cash?
Max Freeman | Epic Cash | Mimblewimble Well one thing I really want to mention is our great Epic Cash community. We’ve been building a decentralized community organically, without the talk of price pumps, pressure to HODL and other BS crypto-gimmicks. Our community is truly global and consists of developers, volunteers, miners, and other Epic enthusiasts spreading the word about Epic Cash, helping us reach millions of people around the world to improve their quality of life through social media and directly. Everyone is an evangelist, everyone is an influencer, everyone has the power to make the world a better place to live in. As we continue to grow — the future looks Epic 😊
Yoga Dude Definitely the community! We got a talented crowd of very cool and motivated people from all over the world!
Oleg✌🏻 Thank you guys, for such informative answers 🙂 Now we proceed to Section 3, where a Community can ask their questions to the EPIC team Now I’ll open chat for the quite some time … Oleg✌🏻 Thank you all, dear community! EPIC team, please choose the 10 best questions you want to answer.
AngeI Everyone likes Privacy & Epic Cash provides their Best Privacy to users But, Which Technologies are being used by Epic Cash to make Blockchain very Private and Completely untrackable ?
Max Freeman | Epic Cash | Mimblewimble From the wallet to the node, Epic uses Dandelion++ to bounce transactions around the world before they go into the mempool for mining. Within the blockchain itself, Cut-Through merges all transactions in a block together, with CoinJoin automatically mixing all coins.
Beyond that, there are no addresses, so it’s impossible to watch someone’s wallet.
Arnold Even litecoin is implementing mimblewimble, Don’t you think it’s a significant threat for Epic if they implement it, then why would anyone use a less popular and a new cryptocurrency.
Max Freeman | Epic Cash | Mimblewimble LTC is implementing mw as an “extension block”, meaning that it is optional and not all transactions will use it. This is very different than the core protocol leveraging mw to make all transactions private and all coins fungible.
Aluta Why Epic cash so much focus on fungibility? Does fungibility matters that much?
Max Freeman | Epic Cash | Mimblewimble Fungibility is going to be one of the key issues within the cryptocurrency space in the coming years. Today, if you accept traceable coins from a seller, you are liable if they have ever been used in any illegal activity. This has led to a two tier market where freshly minted coins sell for more than circulated coins. When coins are fungible, like Epic, you don’t have to worry that you will run into a problem when an exchange or merchant blocks your transaction.
Joxes It is a pleasure.
When I first researched EpicCash, google showed me a youtube video that talked about how to mine with EpicCash. It made me ask: is this mining activity profitable so far?
We are in the early stages of development I guess, what adoption strategies are you taking to have sustained growth? is it feasible to reach N ° 500 rank in coinmarketcap in the medium term?
Yoga Dude When I got into crypto, it was by mining Bitcoin back in 2011 when you could still solve blocks on a single computer, but Bitcoin at the time was anything but profitable 😄 Today Epic Cash is still new, still young, and still undervalued. I believe it is mining-worthy because of its potential, not because of today’s price. By allowing Epic Cash to be mined with GPU and CPU on gaming rigs, servers, and even laptops we offer maximum public participation in our project. More people involved in the project, the more evangelists there are. We empower people to mine Epic Cash and to promote it.
S.P.A.D.E What new features of Epic Cash provide that Grin or Beam does not offer. Why do we need Epic Cash?
Max Freeman | Epic Cash | Mimblewimble They are great coins, but there are some ways in which Epic improves. Epic has better tokenomics than Grin and a more sustainable model than Beam, that has a company behind it that needs to repay investors via its high dev tax. this article explains in more detail https://medium.com/@frodofreeman/overview-of-mimblewimble-cryptocurrencies-7c70be146f50
Sahil What’s the Minimum Hardware / setup Required for Mining of EPIC Cash coins? Is Mining Profitable and Can we Mine EPIC Cash coins at Home?
Max Freeman | Epic Cash | Mimblewimble It is possible to mine on an ordinary laptop or desktop from the last 5 years, sometimes older. Epic is open to everyone, and our friendly community is standing by to help you get started at t.me/epicminers
Erven James Sato “TOKEN BURN” is BENEFECIAL for any projects, in able to CONTROL THE NUMBER OF TOKEN CIRCULATION and TO PROVIDE GREATER INCENTIVES TO INVESTORS.
Does your GREAT PROJECT have plan about TOKEN BURN?
Xenolink For deflating projects It is beneficial to drive the demand / scarcity / and price up in a faster pace. Epic Cash is here for the organic long run not the short run. However when it comes to long term economics elastic supplies whether inflating or deflating will not be a solid long term economic model. This has been heavily discussed already with Bitcoins inelastic Fixed 21 million supply in the past. Having a fixed model demonstrates good long term economics without worrying about balancing a deflating/inflating model. Bitcoin is a perfect example of a 21 million inelastic fixed supply model that has been proving itself till today. Which is why we are also using the same fixed 21 million supply model. Epic Cash plans to have a solid organic long term future to bring free private fungible money and make this world a better place.
Red Z🔥🤙 No one predicted the COVID-19 pandemic while developing their business model. But the crisis and recession of the global economy is our present with you and it affects all sectors, including blockchain. Will you make or have already made changes to the project roadmap, tokenomics? Do you have a plan in case the situation does not improve in the coming months and will affect the crypto industry even more?
Yoga Dude One thing we have seen as the result of the COVID-19 is more governments are talking about moving to digital cash — digital dollar in USA, digital Lira in Turkey, etc… If in the past the idea of digital money was not graspable by some people, today its the governments that are educating the people for us about the value of digital currency… What is ironic, the governments, by printing money to solve the economic consequences of COVID-19 also educating the consumer about the true “value” of fiat… What we offer is a touch free, borderless, private, anonymous, fungible currency that can not be printed beyond the initial defined algo. We are more responsible than the printing presses of the governments 🤔
kunlefighter How does the Dandelion++ Protocol, Confidential Transactions (CT) and CoinJoin assist in protecting the privacy of individuals and their transactions on Epic Cash Blockchain?
Max Freeman | Epic Cash | Mimblewimble Dandelion++ bounces transactions around before committing them to the blockchain, making it impossible to determine where they originated from. Confidential Transactions means that all tx are private, you can’t tell anything about where the coins have been or who they belonged to. CoinJoin in essence melts down and re-mints each coin every time it is used, making it impossible to track their ownership or usage history. Epic provides comprehensive privacy to everyone, without the compromises that other pre-mimblewimble coins have.
Dr Mönica Hello sir @maxfreeman4 @Johnsstec @Yogadude
Thanks for the ama I notice that Epic Cash has 2 type of new algorithm, progPoW version 0.15.0 and randomX version 1.0.3 NOW , CAN you tell me why you choose these 2 algorithm???
Yoga Dude We went with RandomX because it is a solid and very popular CPU centric algo used by several coins — most recently Monero. Most miners today heavily favor ASICs or GPUs, leaving a lot of solid high end users in the dust unable to mine emerging cryptos. As far as ProgPow, again its an established algo for GPU miners, and thanks to many cryptos starting with Bitcoin/Monero/Ethe etc there is no shortage of GPU rigs out there :) plus again the casual user with a video gaming caliber card can get in on the action.
Oleg✌🏻 Perfect! It was a great AMA, but it is coming to an end, thanks to everyone who was with us. Thanks EPIC team for taking the time👏. I hope our projects will be able to collaborate even more closely in the future and achieve new successes. Cheers!🎉

Numbers on the screen or how digital payment systems make the market fair?

Numbers on the screen or how digital payment systems make the market fair?

https://preview.redd.it/6m1gp2mvotx41.png?width=1160&format=png&auto=webp&s=a83f0346d8008c17968d6a240cfba8fe3fe4e2aa
Continuing the trend of practicality characteristic of the XXI century, paper money is gradually disappearing from our lives, giving way to more practical digital storage. However, the digitized banking that we now use every day is still far from perfect. For starters, it is completely controlled by third parties. No one owns the numbers they see on the screen — control is entirely owned by third parties, such as banks.
Banks create money out of thin air, and credit is a prime example of this. Money is no longer printed when someone takes out an overdraft or mortgage-it is simply created out of nothing. Moreover, these banks charge disproportionately high fees for the services they provide, and these services are outdated and impractical today.
For example, it is impractical to pay a Commission to spend your money abroad, as it is impractical to wait a few days to verify the transfer of a small amount from You to your relative. All this makes no sense in the interconnected and instantaneous world in which We live today.
Thus, the monetary system has ceased to be practical, it is replaced by a higher form of value storage. In this particular case, it is replaced by a faster and safer system that eliminates expensive operations and gives control to the person.

Money that you have in your Bank account can be considered a virtual currency since it does not have a physical form and exists only in the Bank book. If they lose the book, your money will simply disappear. These are just numbers that you see on the screen. The numbers are stored on the hard drives of Bank servers.

https://i.redd.it/4nvhydtzotx41.gif
Do you open a regular app and think you have money? They are just bytes of the computer system. Today’s global payment infrastructure moves money from one payment system to another through a series of internal Deposit transfers between financial institutions. Since these transfers occur in different systems with a low level of coordination, the calculation of funds is slow, often 3–5 days, capturing liquidity.

How do payments work?

When you make a money transfer, for example, from your Bank card to the Bank card of a friend or acquaintance, you see an instant transfer, so to speak, moving numbers from you to the Recipient. For the user, the transfer is carried out instantly, and the exchange of obligations between the participants of the process takes place within 3–7 days, the User does not know about it and hardly ever thinks about it.

When you make a payment at a supermarket or any other point of sale, at the time of payment, information from the POS-terminal is sent to the acquiring Bank — then the acquiring Bank sends a request that passes through the payment system (Visa or MasterCard) and then transmitted to Your Bank, which confirms the operation. At this point, there is no write-off of funds. The funds are temporarily held, and the actual withdrawal will take place within a few days, the maximum processing time is up to 30 days.

Currency transactions and payments abroad

You may have noticed that after making a transaction in a different currency, such as yen or dirhams, or any other currency that differs from the currency of your account or buying an item abroad, the amount charged may differ from the amount that was reflected immediately after payment.

Why is this happening?

As soon As you have made a transaction with Your Bank card — the local Bank transfers the information to the payment system: Visa or MasterCard — the payment system converts the currency used into the billing currency.
Billing currency — the currency that will be used for payment with the payment system by your Bank that issued the card. For the US, the billing currency is the dollar, in Europe — the Euro.
The billing currency may also differ depending on the issuing Bank — the Bank that issued your debit card. For example, some banks use the billing currency — Euro when making payments with MasterCard cards in the United States, which will lead to additional costs when converting euros into dollars.
If the payment is in other currencies, the payment scheme will become more complicated and, accordingly, its cost will be more expensive. The transfer rate from one settlement currency to another is set by the payment system: Visa and MasterCard.
If the currency of your Bankcard is the same as the currency of the payment system, the payment will take place without additional operations. For example, You have a dollar card, you make a payment in dollars in the United States, and if you make a payment with a dollar card in Europe, your Bank will convert the amount at its exchange rate, which will lead to additional costs. There are exceptions, some European banks can use dollars for settlements, but this is more an exception than a rule.
Also, if, for example, you pay for purchases in China using a Bank card in euros, then double conversion is inevitable.
Thus, payment in dollars is universal all over the world, except for the European Union countries. The dollar is a global currency and is therefore often used for binding in international settlements.
Now we understand that due to differences in the account currency and the differences in the VISA or MasterCard payment system, additional conversions may occur, which will lead to additional bank fees. as a result, the actual payment amount will differ from the amount debited from your card.
In addition to paying for conversion in the payment system and paying for currency conversion in your Bank, some banks charge an additional fee for conducting a cross-border transaction.

Where do we lose money when making debit card payments?


https://i.redd.it/tykhrd56ptx41.gif
  1. Currency conversion by the payment system;
  2. Euro-Dollar, or in the case of processing payment via MasterCard in Turkey, Turkish lira-Euro and additional conversion on the side of the issuing Bank (your Bank) Euro — Dollar.
  3. Currency conversion by an acquiring bank;
  4. The difference between the exchange rate on the purchase date and the write-off date. We purchased at a rate of 0.91 euros per dollar, and the write-off occurred at a rate of 0.94 euros per dollar.
  5. A large number of currency conversions.
  6. The greater the number of them, the more we will lose when buying. For example, when paying in the UAE or China, buying a product for the local currency, we understand that the number of conversions increases several times.
If we touch on the topic of international translations, we will encounter additional nuances:
  • This is the payment processing time. International payments can be processed within 3–5 days, as mentioned above, which in our dynamic time — it interferes with the comfortable use of the system.
  • Restrictions on the amounts;
  • Possible requirements for certain documentation for payment confirmation;
  • Additional fees and commissions, sometimes hidden fees.
It is not always possible to make a transfer quickly and when necessary due to these restrictions. All this confirms the complexity of the operations and additional commissions that the user pays.

Сryptocurrency exchanges

And now back to the numbers on the screen, this topic affects not only banks but also centralized cryptocurrency exchanges:
  • You top up your Deposit on the exchange in cryptocurrency-then you use numbers inside the exchange, and real funds are most often stored on “cold storage” for which administrators or other responsible persons are responsible.
  • Only when you make a withdrawal from the exchange to your wallet-you are sent real funds (tokens or cryptocurrency).
The same applies to centralized applications and online services that deal with cryptocurrencies:
There are many services, both online and apps, that are centralized, regardless of what they will be called: Bitcoin wallet or bitcoin exchange. This means that when you add funds to an account in such a wallet, the funds are stored on the developecompany’s side. In simple words, all your funds are stored in the wallets of the system’s creators.
If you use a centralized app, you have a risk of losing funds. Although the application is called cryptocurrency, it does not affect its main principles — it is decentralization.
In other words, using systems where there is a Central authority, especially in the cryptocurrency market — the risk increases, so we recommend using decentralized systems for storing currency to reduce risks to a minimum.
Decentralization is the process of redistributing, dispersing functions, forces, power, people, or things from a Central location or governing body. Centralization is a condition in which the right to make the most important decisions remains with the highest levels of management.

Peer-to-peer payment systems

The opposite and standard of security and independence are peer-to-peer payment systems. Using the application-level network Protocol, clients running on multiple computers connect to form a peer-to-peer network.

https://preview.redd.it/ojcg4fz7ptx41.png?width=601&format=png&auto=webp&s=6cc81d1617b0cb64a3f5c7cc6d06a78354386f8c
There are no dedicated servers in such a network, and each node is both a client and performs server functions. In contrast to the client-server architecture, this organization allows you to maintain the network operability with any number and any combination of available nodes. All nodes are members of the network.

https://preview.redd.it/npttc3a9ptx41.png?width=1000&format=png&auto=webp&s=0f2dee1e5b19436a847dca96e2b3b7f22b801b57
Tkeycoin is a decentralized peer-to-peer payment system based on p2p principles and the concept of electronic cash. P2P technology is a fairer means of mutual settlements between users and companies around the world. Modern payment systems are imperfect and may depend on the will of high-ranking officials.
The main goal of Tkeycoin is to create universal products that will make financial transactions more accessible, profitable and secure.

https://i.redd.it/gk6j0m9bptx41.gif

What do decentralized systems protect against?

Using decentralized tools, for example, a local Tkeycoin wallet or a Multi-currency blockchain tkeyspace wallet — Your funds belong only to You and only You can use them, which eliminates the risks of third-party bankruptcy, and such a decentralized architecture can also protect against natural disasters. Given that there is no central server that can be damaged in a natural disaster, the system can work even if there are 2 nodes.

https://i.redd.it/sb6i2ladptx41.gif
In addition to force majeure situations, you protect your funds from theft and any sanctions from third parties-in our time, this is very important. The owner of Tkeycoin does not need Bank branches, does not need additional verifications, and does not need permission to use, transfer, or even transport Tkeycoin. You can easily carry $1 million worth of Tkeycoin in your pocket and even in theory not know any troubles.

https://preview.redd.it/uvw9vfyeptx41.png?width=1400&format=png&auto=webp&s=14b89acca3568fdc5eb82d986aaa2710219ced91
Besides, it is extremely convenient and safe to store even multibillion-dollar capital in Tkeycoin. Imagine that you have a lot, a lot of money, and you need a safe place to store it. Where do you apply? Of course, the Swiss Bank, Yes, but it can easily freeze your accounts and you can easily lose your savings. In recent years, many banks are actively fighting against gray non-cash funds (including offshore ones), and every month more and more legal proceedings are organized on this basis.

https://preview.redd.it/vodiuq5gptx41.png?width=1400&format=png&auto=webp&s=31ab44da4431b0159ef1213db7e37c6fd92d5b0a
The fact is that serious money, for the most part, has a gray tinge, and only a tiny fraction of billions and millions are clean for the law. That is why their owners are often called to court, subjected to pressure, forced to leave the country, and so on. If your money is stored in Tkeycoin, you will not be subjected to such pressure and will avoid the lion’s share of troubles that usually accompany accounts with many zeros.
Using peer-to-peer systems — you will not be called by a Bank Manager and require documents or a fraudster who asks for Your card number and SMS for confirmation. This is simply not the case, wallets are encrypted, and using different addresses guarantees privacy.
As for fees for transfers, there are no Visa or Mastercard payment systems, as well as additional fees that we discussed above.

How are payments made in the Tkeycoin peer-to-peer payment system?


https://i.redd.it/9ftct10iptx41.gif
As soon as you sign a transaction, it is sent to the blockchain and the miners are engaged in its confirmation, for which they take a symbolic Commission. Let’s look at an example, the key rate is $1, the transfer fee will be 0.00001970 TKEY or 0.00000174 TKEY.
0.00001970 TKEY=$0.00001970 0.00000174 TKEY=$0.00000174
Accordingly, commissions are almost zero. In Europe, on average, you will pay $15–20 for a small Bank transfer.
For example, now sending 1 million dollars to BTC, You will pay a Commission in the area of ≈3–8 dollars. Just think, 1 million dollars, without restrictions, risks, and sanctions, and most importantly, the transaction will be the available day today, and you paid an average of ≈5 dollars for the transfer.

Transactions in the Tkeycoin blockchain

Now let’s touch on the topic of how a transaction in the blockchain goes. Once you have sent a transaction, it will be available to the Recipient. The transaction takes place instantly and the User sees not” numbers on the screen”, but real funds-cryptocurrency. This is very convenient when you make any transactions and the Recipient needs to make sure that the payment came.
In the full node-there is a choice of confirmation blocks — this is the amount after which you can use the received cryptocurrency. When sending, you can select the number of confirmations:
• 2 blocks≈10 minutes • 4 block≈40 minutes • 6 blocks≈60 minutes • 12 blocks≈120 minutes • 24 blocks≈4 hours • 48 blocks≈8 hours • 144 blocks≈24 hours • 504 blocks≈3 days • 1008 blocks≈7 days
As we can see, you can also set a weekly confirmation if necessary. The minimum recommended number is 3 blocks. by default, the full node (local wallet) has 6 blocks installed. The presence of this number of confirmations ensures that Your block will not be forged and will be accepted by the network.
Each new transaction that receives network approval is sent to mempool, where it waits for miners to confirm it. When a miner takes a transaction to include it in the next block, it automatically receives the first confirmation.

Generating blocks in the TKEY network

A block in the TKEY network is generated within 6–10 minutes. the network automatically corrects the complexity and time of block formation. Thousands of transactions or a single transaction can be placed in a block.

https://i.redd.it/f9d17k8uptx41.gif
Transactions work faster in the TKEYSPACE app because we have already enabled new algorithms and this is now the fastest and most convenient way to exchange various digital currencies.

https://preview.redd.it/nnz5krdvptx41.png?width=1400&format=png&auto=webp&s=fee452ae6389c8f46d97357777193ed2b10bc4bc
Anyway, using the full node is also one of the safest ways to store and send Tkeycoin cryptocurrency, and most importantly, the full node stores a full copy of the entire blockchain, which benefits the network and provides protection from information forgery.
The more popular the project becomes, the more load is placed on the network itself. For example, 10,000 transactions passed in one block that was processed quickly, while the other 10–20 transactions in another block hung for a longer time, so temporary “pits” may appear. To deal with them, we are working on implementing additional chains-separate chains that are created for cross-transactions, which ensures fast payments under heavy load.
For the global system — we get a shipment around the world in 6–10 minutes, in cross-chains in 10 seconds. In comparison with the global payment system, which processes cross — border payments within 3–5 days, this is a huge advantage. If we add liquidity to this, we will get a perfect payment system.
https://preview.redd.it/2d0uu4gxptx41.png?width=1200&format=png&auto=webp&s=ae5f2f0bc8b7c7dedd1814eb32e97092a6330c3a
Also, you should not forget that if you did not sync with the network and sent a transaction, the transaction may hang in its memory pool and you will have to perform several actions to solve this situation. Here we must understand that syncing with the network is an important point because if you have a connection failure in the Internet Bank, the payment will also not be processed. After all, it will not be sent to a specialist for confirmation.
If you are currently experiencing any delays with transactions, this is due to the transition of CPU mining to GPU, as soon as miners switch to new mining methods, the confirmation of blocks will be consistently fast.
In conclusion: blockchain is a new technology and many terms, concepts and how it all works are still difficult for many to understand and this is normal from innovation.
In many countries, the word cryptocurrency and blockchain are synonymous and no one wants to understand the reality, most people believe that if the blockchain, it means it is related to trading on the cryptocurrency exchange. No one thinks about the real usefulness of certain solutions that will become commonplace for Us in the future.
For example, the Internet banking system dates back to the ’80s of the last century, when the Home Banking system was created in the United States. This system allowed depositors to check their accounts by connecting to the Bank’s computer via their phone. In the future, as the Internet and Internet technologies develop, banks are beginning to introduce systems that allow depositors to get information about their accounts via the Internet. For the first time, the service of transferring funds from accounts was introduced in 1994 in the United States by the Stanford Federal Credit Union, and in 1995 the first virtual Bank was created — Security First Network Bank. But, to the disappointment of the founders of the project, it failed because of strong distrust from potential customers, who, at that time, did not trust such an innovation.
Only in 2001, Bank of America became the first among all banks that provide e-banking services, the whole user base for this service exceeded 2 million customers. At that time, this figure was about 20 % of all Bank customers. And in October of the same year, 2001, and the same Bank of America took the bar in 3 million money transfers made using online banking services for a total amount of more than 1 billion US dollars. Currently, in Western Europe and America, more than 50% of the entire adult population uses e-banking services, and this figure reaches 90% among adult Internet users.
Life changes, and in the bustle of everyday work — we do not even notice how quickly all processes change.
We are experiencing a technological revolution that is inevitable.
