Bitcoin Testnet: A Beginner’s Guide to Using the Bitcoin

cant connect bwt to bitcoin-core

im testing the latest version of electrum that let you connect to bitcoin-core using a plugin. Everything goes fine until i press save and connect:
ERROR bwt » JSON-RPC error: JSON decode error: EOF while parsing a value at line 1 column 0
if i enable the trace option:
INFO bwt » DEBUG bitcoincore_rpc > JSON-RPC failed parsing reply of getnetworkinfo: sonRpc(Json(Error("EOF while parsing a value", line: 1, column: 0)))
im using bitcoin-core 0.19.1 and electrum 3.3.8 and the plugin version bwt-plugin 0.1.1 and 0.1.2 amd_x86_64
edit: finally it worked!!! electrum is conected to 1 node, that is my node, now im gonna try to connect a cold wallet!!

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Public CodeValley/Emergent Consensus questioning and investigation Thread. Ask your hard questions and dispel your doubts here.

What is going on here?
I am asking some hard questions for the CodeValley Company, which recently proposed a new revolutionary software development paradigm called Emergent Coding at the latest big Bitcoin Cash conference in Australia.
I am asking these questions because, as I (and ~150 people who agreed with me) noticed, there are stunning similarities between CodeValley and the companies who have tried and succeeded in crippling Peer-To-Peer Electronic Cash: nChain and Blockstream.
According to me, as it looks now, similarities between these 3 companies (nChain, Blockstream, CodeValley) are the following:
}- Sources of funding are extremely unclear or openly hostile to Bitcoin
}- At first and even second glance, there is no product, no way to make money
}- Whitepaper & Documentation is missing, hollow or total abstract bullshit, company has no logical sense of existence
}- Detailed specifications or proofs of operation are not available
}- Main products are closed-source patented blobs (BSV, Liquid, Emergent Coding)
}- They have huge influences in the industry or try to establish themselves in such position to have the infuences
I am here (and you are here, I assume) because we want to find out the truth, whatever the truth is. The point of this topic is to ask the hardest possible questions in order to estimate the probability of CodeValley company being legit.
But this is also a chance for CodeValley to clear their name by providing sufficient information that proves that (after 4 years of having working company and 10+ years of having patents [Archived]) they actually have a working product and are a legit company, and not an infiltrator designed and paid by banks/TPTB in order to cripple and destroy Bitcoin Cash. Also if they truly are what they claim and they truly have such a revolutionary technology, this is a great opportunity for promotion. To show the world that the tech actually works.
I will ask my questions and you can ask your questions as well. Don't make them easy. Don't have mercy (but these things work better when you are polite).
Let's begin the trial by fire!
Calling nlovisa
My Questions/Tasks for CodeValley:
[Of course you actually don't have to answer any of them or you can give us bullshit answers again, but in such case the community may conclude that you actually are next nChain/Blockstream and an enemy infiltrator, reject you and shoot down all your efforts. So the choice is yours]
@@@@ 1. Please upload your actual businessplan which you presented to the people in power who gave you funding(VCs? Government?) to create $50 Million BCH tech park. A businessplan which is supposed to explain spending of $50 million AUD should have at least 7 pages (but more probably 20+). Some names and unimportant details (but NOT money/financial numbers) can be redacted.
-- You have 6 hours to complete this task --
@@@@ 2. Please list your current VCs and >%5 shareholders, with CEO names and HQ locations of each of them.
-- You have 4 hours to complete this task --
@@@@ 3. Few days ago you promised to upload freely-accessible documentation to https://codevalley.com/docs subpage which would describe emergent coding in greater details.
@ - What happened to that promise?
@@@@ 4. After I accused that your company is bullshit and your product is hollow, you immediately started to praise me and offered me a trip to Australia [Archived].
@ - So, do you always praise and offer a paid trip across the world to Australia to all people on the Internet who heavily criticize you? Is this a common practice in your company?
@@@@ 5. A travel from Poland to Australia and back would cost something under $2000 AUD, counting buses, with hotels that would make something close to $2500 AUD even for few days. Based on this, I estimate your "invite random people from the internet to Australia in order to show them the product" budget has to consist of at least $50.000 AUD yearly (but $100.000 - $200.000 is more probable of course).
@ A) In your financial books, what exactly is called the Excel position of your budget expenses under which would your secretary put my trip's expenses?
@ B) How do you maintain such a large budget for such frivolous spending and how do you explain it to your shareholders/VCs?
@@@@ 6. Few days ago you answered somebody a question: "The trust model is also different. The bulk of the testing happens before the project is designed not after. Emergent Coding produces a binary with very high integrity and arguably far more testing is done in emergent coding than in incumbent methods you are used to.".
@ A) Who EXACTLY does the testing? People? Software? AI? Non-bullshit answer, please.
@ B) Why exactly is there "more testing" in Emergent Coding than in normal software creation paradigm? Why is emergent coding different? Do the developers who work in this paradigm are somehow special? Are the programming languages magical?
@ C) What are the specific software tools used for this "testing"? "Agents" is a non-answer, so don't even try.
@@@@ 7. Please provide a simple demo binary of a simple program created completely using your "Emergent Coding" and also provide all the binary sub-component files that make up the final binary.
Requirements: There has to be a minimum of 3 sub - binaries making up the final big binary for this to be valid. 2 or less does not count. None of the binaries can be obfuscated, they have to be clean X86/X86_64 machine code binaries.
Notes: It should be incredibily simple, quick and easy task for you, since designing such a complex and apparently breakthough system must have required thousands, tens of thousands if not hundereds of thousands tests. All of these tests produced working binaries - after all you wouldn't claim you have a working marvellous revolutionary product without extensive testing, right?
-- You have 18 hours for this task --
Of course, If you are saying the truth and have truly developed this revolutionary "emergent coding" binary-on-the-fly-merging technology, this should normally take you under 18 minutes to just find the test samples and upload them.
@@@@ 8. Please construct a simple (binary or source) single-use-compiler demo that will combine 3 or more sub-binaries into final working product. Please upload the sub-binaries and the "single-use compiler" to publicly available site so people in our community can verify that your product is actually working.
The single-use-compiler binary can be obfuscated with proper tool in order to hide your precious intellectual property. The 3 sample sub-binaries cannot be obfuscated. They have to be pure, clean, binary X86/X86_64 machine code. Everything has to be working and verifable of course.
-- You have 72 hours to complete this task --
I understand all your technologies are patented with patents that basically predate Bitcoin and you are giving us obfuscated binaries, so you don't have to worry about anybody stealing your company's intellectual property, right?
@@@@ 9. You mentioned the only application I need to create programs using Emergent Coding is the pilot app.
@ - What programming language(s) is the pilot app written in?
@@@@ 10. When you developed the Emerging Coding, before it started existing, you couldn't have used emergent coding to create the first (test & development) applications because it is a chicken and egg problem.
@ - What programming language did you use to create first client/serveapi/daemon/tool used to merge multiple binaries into one in Emergent Coding?
@@@@ 11. Please list all of your current programmers and programming language each of them is using next to their name. Also provide LinkedIn profiles if applicable.
-- You have 18 hours to complete this task --
@@@@ 12. Please also list all Development Environments (IDEs) used by your current programmers next to their name.
-- You have 18 hours to complete this task --
@@@@ 13. Please list all compilers used by your current programmers next to their name.
-- You have 18 hours to complete this task --
@@@@ 14. So if I understand correctly CodeValley will be the company who runs $50 million BCH tech park and the tech will house multiple Bitcoin Cash-related startup and companies. Let's say I have a BCH startup and I would like to rent a loft/spot in your "tech park".
A) Please provide a PDF of sample basic contract you have (hopefully) prepared for such startups.
-- You have 4 hours to complete this task --
B) How much does the rent cost per a room (or m2/sqft) for a month and for a year?
@@@@ 15. Please submit the list of compilers that produce X86/X86_64/ARM binaries compatibile with Emergent Coding "mash-it-together" "binary compiler".
-- You have 4 hours to complete this task --
@@@@ 16. Is it possible for Emergent Coding to merge multiple non-binary applications (like Python or PHP programs) together? Or is it just binaries?
Who are you?
I am a freedom thinker and individual independent from all infuences who just does what he finds appropriate at the moment. Disclaimer to preempt questions:
}- I do not work for anybody
}- I do not have any hidden agenda
}- I am only doing what I think is right
}- I am a born revolutionist, this is why I am in Bitcoin
Why are you doing this?
}- Because I believe in truth above all. Truth will save us.
}- Because I believe in Satoshi's peer-to-peer cash for the world vision and I will not stray from this path.
}- Because most people are apparently missing psychological immune system which is why attempts like Blockstream, nChain appear and are repetedly [at least partially] successful. I have an anti-bullshit immune system that works great against this type of attacks. I was actually one of the first to be banned in /Bitcoin sub for pointing out their lies with manipulations and to spot Craig Wright's attempt to infiltrate and bend /btc sub to his will..
}- Because I was fooled twice by entities similar to CodeValley before (namingly nChain and Blockstream) and I will not be fooled again. Bitcoin Cash will not be co-opted easily as long as I am here.
}- Because if Bitcoin Cash community is an organism, then I became a B lymphocyte cell. I produce antibodies. I show you how to defend yourself from bullshit, lies and manipulation. This is my basic function.
}- Because I am here to kill the bank

Quick Intro to Gemini's API: Learn Some Python, Save on Fees (0.35%)

There's been recent Gemini news with their new platform rollout and increased fee schedule. I know many users are unhappy and looking for new exchanges. It can take awhile to get verified somewhere else, so in the meantime, this prompted me to learn a bit about using API's as I've never done so before. This is also coupled with my desire to eventually learn python. I took an afternoon and figured it out for myself and saved some money on fees. I'll share what I have so far with the Disclaimer that I am NOT a programmer; however, the code is pretty basic and somewhat self-explanatory.
 
I'm on Windows 7 x64 Ultimate. I installed the latest Python for Windows binary first. It installed x86 version of python; that is fine. Now you need two additional packages: requests and pywin32. Open a command prompt, also called cmd.exe, by finding it in accessories or searching for it. You can also hit Windows Key + R, type cmd then hit Enter. From here, try pip install requests or try python -m pip install requests Next install the pywin32 package pip install pywin32 or python -m pip install pywin32 You can also install its binary from here. You want to grab the version that matches your Python install not your OS bit. Mine was the last one, Win32 Py3.7. Take a read through Gemini's API reference page. It's okay if you don't understand everything. For placing orders, we're using the API private client, which requires you to generate a key and assign it a role. This can be done in Settings, API Settings. I assigned mine a role of Trader. I can still deposit/withdrawal on the web interface and don't need the API for that as there's no benefit really, for me at least. The API Key is akin to a public key, and the API Secret is akin to a private key. Instead of having my API secret sitting in plain text on my computer, I decided to keep it in my Trezor's password manager. The script that I edited/made, pulls the secret from the clipboard, submits the order, then clears the clipboard. This isn't as secure as my Bitcoin private keys, but to me, it reduces risk drastically and also prevents accidental buy orders.
 
Python scripts possess the extension, .py and if your computer is configured correctly, are directly executable by double-clicking them. For this use, I would recommend having a bit more control and running them through command prompt. In your main Windows user folder, create a folder called Gemini and put the two scripts there. There is a Test Secret script and a Buy Order Example script. You need to give these files the .py extension either by renaming them or opening in Notepad, resaving ending in .py with All Files as file type. Now, read through the scripts and paste in the required info. I would start with the Test Secret script to test your Python setup and see if you can pull a secret correctly from the clipboard. Go into the script and copy the practice secret. From the command prompt, navigate to this folder. My prompt starts in my user folder, so I can do cd Gemini and it should take you there. Now you can run the script by typing with the quotes "Test Secret.py" or python "Test Secret.py" You should see your secret twice, with the second one looking like b'some string of characters'. If you get a TypeError / Clipboard error, try copying the text again. If this is successful, edit the Buy Order Example script to create a new order, save the script. Copy your actual secret to the clipboard and run in command prompt in the same way. "Buy Order 1.py" Remember the Buy Order script is runnable, so once you copy your actual secret, it's locked and loaded. Be careful! I want to give a nod to mtusman who created the gemini-python client, link to github. This provides a more streamlined Python approach and covers all of the API's functionality. Let me know how it goes.

Decred Journal – August 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link) to see all the links.

Development

dcrd: Version 1.3.0 RC1 (Release Candidate 1) is out! The main features of this release are significant performance improvements, including some that benefit SPV clients. Full release notes and downloads are on GitHub.
The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCkB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades.
Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat.
The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here.
The testnet was reset and bumped to version 3.
Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network.
@matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting.
dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system.
Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration.
Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers.
@degeri joined to perform security testing of Politeia and found several issues.
dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements.
The upcoming v3.0 entered beta and is deployed on beta.dcrdata.org. Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on alpha.dcrdata.org.
Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK.
iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds.
Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes.
docs: introduced new Governance section that grouped some old articles as well as the new Politeia page.
@Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals.
decred.org: 8 contributors added and 4 removed, including 2 advisors (discussion here).
decredmarketcap.com is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required.
Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)

Network

Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%.
Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply.
Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.

ASICs

Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design.
Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15.
FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25.
Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).

Integrations

www.d1pool.com joined the list of stakepools for a total of 16.
Australian CoinTree added DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports.
Three new OTC desks were added to exchanges page at decred.org.
Two mobile wallets integrated Decred:
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?

Adoption

Merchants:

Marketing

Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here.
Contribution to the @decredproject Twitter account has evolved over the past few months. A #twitter_ops channel is being used on Matrix to collaboratively draft and execute project account tweets (including retweets). Anyone with an interest in contributing to the Twitter account can ask for an invitation to the channel and can start contributing content and ideas there for evaluation by the Twitter group. As a result, no minority or unilateral veto over tweets is possible. (from GitHub)

Events

Attended:
For those willing to help with the events:
BAB: Hey all, we are gearing up for conference season. I have a list of places we hope to attend but need to know who besides @joshuam and @Haon are willing to do public speaking, willing to work booths, or help out at them? You will need to be well versed on not just what is Decred, but the history of Decred etc... DM me if you are interested. (#event_planning)
The Decred project is looking for ambassadors. If you are looking for a fun cryptocurrency to get involved in send me a DM or come talk to me on Decred slack. (@marco_peereboom, longer version here)

Media

Decred Assembly episode 21 is available. @jy-p and lead dcrwallet developer @jrick discussed SPV from Satoshi's whitepaper, how it can be improved upon and what's coming in Decred.
Decred Assembly episodes 1-21 are available in audio only format here.
New instructional articles on stakey.club: Decrediton setup, Deleting the wallet, Installing Go, Installing dcrd, dcrd as a Linux service. Available in both English and Portuguese.
Decred scored #32 in the August issue of Chinese CCID ratings. The evaluation model was explained in this interview.
Satis Group rated Decred highly in their cryptoasset valuation research report (PDF). This was featured by several large media outlets, but some did not link to or omitted Decred entirely, citing low market cap.

Community Discussions

Community stats:
Comm systems news:
After another debate about chat systems more people began testing and using Matrix, leading to some gardening on that platform:
Highlights:
Reddit: substantive discussion about Decred cons; ecosystem fund; a thread about voter engagement, Politeia UX and trolling; idea of a social media system for Decred by @michae2xl; how profitable is the Obelisk DCR1.
Chats: cross-chain trading via LN; plans for contractor management system, lower-level decision making and contractor privacy vs transparency for stakeholders; measuring dev activity; what if the network stalls, multiple implementations of Decred for more resilience, long term vision behind those extensive tests and accurate comments in the codebase; ideas for process for policy documents, hosting them in Pi and approving with ticket voting; about SPV wallet disk size, how compact filters work; odds of a wallet fetching a wrong block in SPV; new module system in Go; security of allowing Android app backups; why PoW algo change proposal must be specified in great detail; thoughts about NIPoPoWs and SPV; prerequisites for shipping SPV by default (continued); Decred vs Dash treasury and marketing expenses, spending other people's money; why Decred should not invade a country, DAO and nation states, entangling with nation state is poor resource allocation; how winning tickets are determined and attack vectors; Politeia proposal moderation, contractor clearance, the scale of proposals and decision delegation, initial Politeia vote to approve Politeia itself; chat systems, Matrix/Slack/Discord/RocketChat/Keybase (continued); overview of Korean exchanges; no breaking changes in vgo; why project fund burn rate must keep low; asymptotic behavior of Decred and other ccs, tail emission; count of full nodes and incentives to run them; Politeia proposal translations and multilingual environment.
An unusual event was the chat about double negatives and other oddities in languages in #trading.

Markets

DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery.
@ImacallyouJawdy posted some creative analysis based on ticket data.

Relevant External

StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs.
The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury.
Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue)
Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack).
Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups.
Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems.
Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins.
Finally, unrelated to Decred but good for a laugh: yetanotherico.com.

Come-from-BeyondToday at 5:17 AM In IoT broadcasting is enough to prove that work has been done and that requires few microseconds That technique goes under "NBPoW" codename now
Come-from-BeyondToday at 5:23 AM [Wouldn't a system like this be vulnerable to interference of non-IoT devices?] jamming is possible
Come-from-BeyondToday at 5:25 AM [where is this magical IoT land] In prototyping phase - https://www.youtube.com/watch?v=jV3RpeJNvbU
Come-from-BeyondToday at 5:26 AM [That's a LiFi demo, no?] yes [simply a means of sending data already in use today?] yes, but noone offered a complete IoT solution yet
Come-from-BeyondToday at 5:36 AM [So, NBPoW with LiFi, is that like PoW based on keeping the sending party light emitter occupied with sending the data as a form of proof of work?] No [jamming is possible. is that not a big problem?] Yes, and it's not solved yet. Luckily for LiFi it's much easier to see the location of the jammer.
Eric Hop [IF]Today at 3:29 AM Abra is an intermediate language that is as close to assembler as you can get while still enabling translation to wildly different architectures like x86 and fpga I am in the process of writing a document that explains the Qubic Processing Model and describes Abra as part of that. May take a little while because I want it to be coherent and understandable. The concepts involved are alien enough as it is.
Eric Hop [IF]Today at 6:28 AM I'm currently sitting with Paul discussing things and clarifying things and the conclusions we are drawing about the possibilities of Qubic are staggering. @stanley Abra is not exactly a VM. A virtual machine is usually a piece of software that can be compiled to different hardware platforms and then interprets the virtual machine code. Abra uses JIT-compilation to actually generate target machine code, including hardware like CPU, GPU, and FPGA. There is a Supervisor component, but all that one does is instantiating, loading, JIT-compiling (if necessary), and triggering the code. The Supervisor also handles the sending of events between qubics.
Eric Hop [IF]Today at 6:48 AM Mind = blown. Paul just implemented Curl hash function in Abra as a real-world example of Abra code. Took him less than an hour, and most of it was fiddling with the editor to generate the correct tables. We're trying to get a feel for the language at the moment. Can't wait for the compiler to be ready.
Eric Hop [IF]Today at 7:20 AM Abra is badass. Seriously. Paul and I are deep-diving in what it can do. While discussing it all kinds of light bulbs were going off on both sides. You know how when you have a deep discussion and try to explain what you are thinking to someone else you yourself get a deeper understanding? We've had several of these breakthrough moments within the last 24 hours.
Eric Hop [IF]Today at 7:58 AM We're cleaning up some syntax rules in Abra at the moment. Actually using it in real life highlights where we want things to be simpler to do, or more readable. Once we have that we will probably incorporate those changes and post the Abra Curl function here. Just to throw you guys a bone until we have more extensive documentation.
Eric Hop [IF]Today at 8:55 AM @Werner We have no syntax highlighting modules yet if that's what you are hoping for
Eric Hop [IF]Today at 9:09 AM Right now it looks unlike pretty much anything I have ever seen and yet it seems familiar. We're trying to use familiar constructs as much as possible, yet some things are very different, even if they look like something you already know. The code looks familiar in that you see lots of lines of assignments, array-like tables, and function definitions. It looks unfamiliar in that the usual control statements are completely missing. No if-then-else, no loops. And yet it expresses the intent in a very simple and elegant way if you understand how it works.
8/24
Eric Hop [IF]Yesterday at 11:28 PM [Will Abra have an IDE?] @Zass Initially no IDE. Use your favorite code editor or dev environment. [@Eric Hop [IF] is it possible to use AOT compilation if you were to write something in Abra and distribute it in native code?] @Rajiv Shah Distributing in native code would limit the use of the qubic to the architecture it was compiled for.
Eric Hop [IF]Today at 5:53 AM These things is literally where our community can shine. Creating syntax-highlighting for Abra in multiple dev environments. I would love an IntelliJ syntax highlighter for Abra for example.
Ralf Rottmann [IF]Yesterday at 4:05 AM There is a modified (experimental) IRI node connected to the coordinator, and this node rejected valid transactions due to some minor issues. Once we understood the root cause, we fixed the code in this version of IRI and everything is back to normal.
Eric Hop [IF]Last Friday at 10:52 AM @Ganreizu Since it is a JIT compiler compilation only needs to be done once when a qubic is instantiated and could be cached for future usage. Abra source code will be translated into intermediate trit code representation called Handy, so any translation phase will only need to load that representation of the code tree (no parsing, syntax checking, etcetera is necessary) and then can directly map that code tree to LLVM or Verilog. So it's the qubic packaging process that does the translation from Abra source code into Handy and that happens only once on the side of the qubic creator. This will allow for all kinds of handy (pun intended) tools in the future. We imagine a decompiler that can turn Handy back into Abra source code for example, or an obfuscator that can obfuscate Handy similar to how Java byte code is obfuscated. We also have ideas (very future ideas) for IDE's that can directly emit Handy, or even Evolutionary Algorithms (EA) that can generate optimal Handy trit code directly for certain applications. @empler All this will be open source code. No patents. @thebruce44 It's a functional programming language. With a few twists. Definitely a paradigm shift. But on the other hand it turns out the code is simple and elegant. It's less problematic to directly code into it than we originally anticipated.
8/26
Eric Hop [IF]Today at 2:21 AM [@Eric Hop [IF] hi Eric :nerd: do you know what's happening with exchanges?] Nope. Haven't used exchanges in a while and am too busy with Qubic.
Eric Hop [IF]Today at 3:32 AM After last week I have revised my thoughts about this. Paul and I tried to implement 2 practical applications using Abra. We implemented the old Curl function just for laughs and it was possible and surprisingly easy without excessive bootstrap steps. We then proceeded to implement a key-value store and again it was entirely possible with hardly any bootstrapping, Practical applications will definitely be possible and we will demonstrate that with a cool idea we have for our PoC. Given these encouraging results I revised our chances of having a PoC by end of year from my original personal estimate of 50/50 to 95%. This does not mean Abra has been vetted. The compiler is still under development (80%). And after the compiler is done we will still need to build the Supervisor to be able to run the code as intended. We simply wrote source code that looked as if it should do what we want it to do, just like you can do in any language as a thought experiment without compiling.

Come-from-BeyondYesterday at 4:20 PM [Is there a POS staking reward opportunity in this Economic Clustering? If so, will it have a liquidity function or security function?] no. n/a. but there is opportunity to earn money with Ict

domToday at 1:49 AM [still on holiday?] aye, until the 29th but I'm working ofc
domToday at 1:53 AM [@dom when can we expect an update on the 15 companies that was on sumsum?] @TomTom not sure, it's a bigger project that takes serious effort to setup (several months) [Cfb says "IOTA can be created out of thin air" Is IOTA inflationary?] @drmvb no
domToday at 1:54 AM [Dom. Noticeable improvement in comms recently from the whole team. Much appreech] @Northern🐳😍 agree, there is more room for improvement still
domToday at 1:57 AM [Hey @dom, may I ask about the marketplace update which was said to be given last week? Just curious.] was postponed as we had to hire a new designer for the website (we are adding more pages to explain how the marketplace works etc.)
domToday at 2:04 AM [@dom will iota marketplace be linked to oracles for analysis or is it strictly purchase and keep model?] that will be later
domToday at 2:08 AM [Dom, is IF working with banks at the moment? You mentioned once there are a lot of use cases with IOTA considering PSD2. Is there happing anything behind closed curtains?] @icho yeh of course. We have MOU's with SinoPac and DNB and are working with others
domToday at 2:16 AM [@dom are you feeling the IF is growing to a organisation that is less depended on private individuals?] @TomTom yeh, absolutely
microhashYesterday at 8:38 PM i bought iota a year ago back when most people just barely knew about bitcoin and iota had just been listed on the first major exchange. i held through all the fud while iota matured from a startup to an organized foundation. lots of new partnerships, more exchange listings and now we have ixi hub and a perfectly working wallet. and yet, it's still cheaper than a year ago. if you buy now, think about it like this: you are getting what people bought a year ago back when everything was unclear. and they are getting out at a loss after holding that high risk asset for an entire year. sounds like a fucking opportunity to me.

Groestlcoin ivendPay Integration

ivendPay and Groestlcoin cryptocurrency have announced the start of integration.
IT company ivendPay, the developer of a universal multicurrency payment module for automatic and retail trade, intends to integrate Groestlcoin cryptocurrency — one of the oldest and the most reputable Bitcoin forks into the payment system. Groestlcoin is characterized by instant transactions with almost zero commission and is optimal for mass retail trade where micropayments are mostly used.
According to Sergey Danilov, founder and CEO of ivendPay, Groestlcoin will become the 11th cryptocurrency integrated into the payment module. The first working vending machines for the sale of coffee, snacks and souvenirs, equipped with ivendPay modules, served the visitors of the CryptoEvent RIW exhibition at VDNKh in Moscow and accepted Bitcoin, Go Byte, Dash, Bitcoin Cash, Ethereum, Ethereum Classic, Zcash, Bitcoin Gold, Dogecoin and Emercoin. ivendPay terminals are designed and patented to accept payments in electronic money, cryptocurrencies and cash when connecting the corresponding cash terminal. Payment for the purchase takes a few seconds, the choice of the payment currency occurs at the time of placing the order on the screen, the payment is made by QR-code through the cryptocurrency wallet on the smartphone.
The interest in equipping vending machines with ivendPay terminals has already been shown by the companies of Malaysia and Israel, where first test networks would be installed. ivendPay compiles a waiting list for vending networks interested in buying terminals and searches for an investor to launch industrial production. According to Sergey Danilov, the universal payment terminal ivendPay for the vending machine will cost about $500. The founder of ivendPay has welcomed the appearance of Groestlcoin among integrated cryptocurrencies, as it is another step towards the realization of the basic idea of digital money - free and cross-border access to goods and services for everybody.
