Sobre Tibia, gold farmers y un caso de ayuda y éxito PT2. Son muy buenos consejos de cómo comenzar a programar profesionalmente

Una vez más, reconocimiento al autor original de los post International-Unit-8
Hello,

I have gotten so many replies and messages since my last post in this thread, that I can't answer them all individually. Previous topic:

https://www.reddit.com/TibiaMMO/comments/h8tu5u/a_great_tip_for_brazilians_venezuelans_and_othe

It has been shared on multiple subreddits so I have no idea where to even post this. But I'd like to come up with a follow-up thread with some more information. The internet is the most powerful tool that mankind has ever invented. You have the ability to reach thousands, millions and even billions of people with just a computer and some internet access.

If you're on this subreddit, chances are you're already playing Tibia and you already have a computer and internet access. It doesn't need to be the best internet, but as long as websites will load (eventually) you are good to go.

In this topic I will go more in-depth on web development and software engineering. If you have a very slow internet connection, you may want to look into web development instead of software development. An application/software is much heavier (larger file size) than a website. And most developer jobs require that you send and download files, back and forth, between you and your company's server. So if you feel like your internet is too slow to send a lot of files - do not worry! There are plenty of jobs.

First, I will go through some more details on how to learn web development and software development. After that, I will list a few other kinds of jobs that you can do remotely. These types of jobs can be done from anywhere in the world as long as you have internet access.



Part 1: Some languages you should learn

What is web development? Well, it can be a lot of things. You perhaps make websites for shops/restaurants/hair dressers/dentists, or you work for a big company and work on their web application, like Outlook, Discord or Spotify (which can all be accessed via a browser: their web app). You can also work with design and user experience, instead of programming. Being a web developer can mean so many different things, it's impossible to name them all. But most web developers are just developers: they program. They make websites, and they either sell the websites to companies (as a consultant) or you work full/part-time for a company.

I can not provide in-depth information about every single thing, but I can give you some pointers. The very basics any web developer should know is this:

HTML (HyperText Markup Language) - it's what almost all websites use as a foundation. This is not a programming language, but it is a markup language. If you want to build websites, you pretty much have to know this language. Don't worry though, it is easy. Not so much to learn. You can learn all about it in a few weeks.

CSS (Cascading Style Sheets) - it's what will add colors and shapes to your website. If you want to focus more on design (also known as front end development) then this is where you want to gain a lot of knowledge.

Python - A very simple language to learn. This language is very often the first programming language that developers start using. You can use it for a lot of things. This language is used in the back of a lot of websites. Google has been using Python for years and still is. It's great for web scraping and making web requests. If you want a language to practice your algorithms, then this language is awesome.

PHP - This used to be a very popular language, but not so much these days. However, it is very good to know how this works because it's very simple to learn and also very functional in some cases. If you want to transmit or withdraw information from a database to your website, then this (in combination with SQL) is a great way to do so. Whenever you make a login system or a contact form, the data must be sent somehow to a recipient or a database. PHP will help you do that. It is a server-side language, which means it will run in the back of the website.

SQL - To be able to communicate with databases (for example: save data, update data, or insert data) you can use different languages for that. But SQL is probably the most widely used language for this. It is basically just a bunch of commands that you tell your website or app to do. If you have a web shop for example, you will need a database to store all your product information in. You can for example use MySQL as your database and then use the SQL language to extract data from your database and publish it as a list of products on your website.

JavaScript - Perhaps the most powerful language at the moment. Anyone who is good at JavaScript will be able to learn most other modern programming languages. In recent years, the demand for good JavaScript developers has skyrocketed. It's because more applications are becoming web based, and JavaScript is probably among the most useful languages to use. You can use it for so many things. Previously JavaScript was only being run on the client side of the website (that means in the user's browser). But in recent years, there has been massive development of this language and you are now able to build servers, connect to databases and do very powerful web applications using just this language. A great tutorial for JavaScript was made by Tony Alicea: https://www.youtube.com/watch?v=Bv_5Zv5c-Ts This video is "just" 3.5 hours, but it's the intro. There is a much longer version of it, and you can download it for free if you search for it. Just find it as a torrent and watch it. It's probably the best tutorial I have seen for JavaScript.

C# - It's pronounced as "C Sharp". This language has been dominating the software engineering market for decades at this point. Everyone loves it. It's relatively easy to learn and you can build a lot of stuff in C#. It's very much like JavaScript, but focuses more on application development rather than website development. I would however try to avoid learning this language if you have very slow internet, since you will most likely be sending a ton of files back and forth. But if application (computer & phone) is your thing, then this language is great. There are so many tutorials on this, but there is 1 channel on YouTube which teaches a lot of the basics in C# (and many other languages) and that channel is called ProgrammingKnowledge. Sure, his C# videos may be old now but most of it is still relevant and useful. You will learn a lot by watching his videos. It's always good to start from the beginning and then when you're familiar with that, you can learn more about the recent updates in C#. https://www.youtube.com/watch?v=V2A8tcb_YyY&list=PLS1QulWo1RIZrmdggzEKbhnfvCMHtT-sA

Java - This is pretty much 90% identical to C# as I wrote above. Widely used, relatively easy to learn the basics and there's plenty of jobs. If you like making android apps, this language is for you.



Part 2: Technologies and useful tools

To become a web developer you will need a few tools. You need a text editor, a FTP client, a SSH client and some other things. Also a good browser.

Text editor: Visual Studio Code, Atom, Sublime Text, Brackets - There are many different text editors but at the moment, I highly recommend Visual Studio Code. It has so many built-in features it's honestly the only thing you may need.Don't forget to install Notepad++ as well - this very basic editor is so handy when you just quickly need to edit some files.

File archiving: WinRar, 7-Zip - You need some way of archiving projects and send it to your customer or employer. These are basic tools anyone should use. I personally use Winrar.

FTP (File Transfer Protocol): FileZilla - This tool will allow you to connect to your website's file manager and upload your files to it. There are many tools for connecting to an FTP server but this is the most popular one, it's simple and it works great.

VPS (Virtual Private Server): Amazon Web Services, Google Cloud - If you want to practice building web applications or want to host your own website as a fun project, it's great to use a VPS for that. Both Amazon and Google offers 365 days of free VPS usage. All you need is a credit card. However, they will not charge you, as long as you stay below the free tier limit. A VPS is basically a remote computer that you can connect to. I highly recommend that, if you have a slow internet connection. Those VPS-servers (by Amazon and Google) usually have 500mbit/s internet speed, which is faster than most countries in the world. You simply connect to them via Remote Desktop, or by SSH. Depending on what type of server you are using (Windows or Linux).

SSH (Secure Shell): Solar-PuTTY, PuTTY - If you for example have a web server where you store applications and files, a great way to connect to it is by using SSH. PuTTY is pretty much the standard when it comes to SSH clients. But I really love the version created by SolarWinds. When you download that one, do not enter your personal details. Their sales people will call you and haunt you! Haha.

File Searching: Agent Ransack - When you have many files and try to locate a specific document or file, you may want to use something like Agent Ransack. Much faster than the traditional search feature in Windows and it is much more accurate.

IDE / Code Editor: Visual Studio - Great tool to use when you want to create applications in C# for example. Do not confuse this with Visual Studio Code. These are two very different tools. This tool (Visual Studio) is more designed for Windows applications. Not just websites. I only recommend getting it if you plan to make programs for Windows.

Web host & domain: NameCheap, Epik, SiteGround - If you develop websites on your own, or maybe want to create a portfolio website, you will need a domain name and web hosting. I have personally used all of these 3 and they are very cheap. NameCheap has some of the cheapest domains and great web hosting for a low price. Their support is also great. Same with SiteGround. And if you want to buy a domain anonymously (with Bitcoin for example), then you can use Epik. Low prices and great customer service on all these 3 websites.

Web Server: XAMPP, Nginx - If you plan to practice PHP, you will need to have a web server on your local computer. If you have Windows, I would highly recommend installing XAMPP (Apache). It is very easy to use for beginners. If you're on Linux, I would recommend Nginx. Also check our PhpMyAdmin if you want to quickly setup a MySQL database locally.Bonus tip: If you use Visual Studio Code to create websites in HTML, CSS and JavaScript: then install the extension "live server" and you can run your applications on a live server without setting it up yourself. Tutorial: https://www.youtube.com/watch?v=WzE0yqwbdgU

Web Browser: Mozilla Firefox, Microsoft Edge Insider, Google Chrome - You need one of the latest web browsers to create websites these days. Since I prefer privacy over functionality, I've always loved Firefox. But recently, Microsoft has been improving its new version of Edge a lot (based on Chromium) and it's also very popular. If you want all your personal details to be saved and have good tools for web development, then use Google Chrome. Don't forget to utilize the built-in developer tools. You can access it in any of these browsers by pressing F12.



Other things you may want to look into:

Web services, SSL certificates, Search Engine Optimization, Databases, API, Algorithms, Data Structures



Part 3: Learning platforms

https://www.youtube.com/

https://www.w3schools.com/

https://leetcode.com/

https://stackoverflow.com/



If you want to learn in-depth about algorithms, data structures and more. Then you can take a look at the curriculum of the top-tier universities of USA. Such as: UC Berkeley, Harvard and MIT. These courses are very hard and are specifically for people who want to become experts in software engineering. You can enroll some of them for free, like the one on Harvard. And by having a such diploma (which costs $90 extra) can get you a lot of job opportunities. You can enroll those courses if you want, but it can have a fee. But just take a look at what they are studying and try do their exercises, that is 100% free. Get the knowledge. It's mostly on video too! These course below are the very same courses that many of the engineers at Facebook, Google, Amazon, Apple, Netflix, Uber, AirBnb, Twitter, LinkedIn, Microsoft, etc. has taken. It's what majority of people in Silicon Valley studied. And it's among the best classes that you can take. These course are held by some of the world's best professors in IT.



UC Berkeley: CS 61a & CS 61b:

MIT (Massachusetts Institute of Technology): 6.006

https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-006-introduction-to-algorithms-fall-2011/

Held by Erik Demaine. One of the best - if not THE best - professor at MIT. Just look at this resume. It's almost 50 pages long! https://erikdemaine.org/cv.pdf



Part 4: Finding jobs

https://www.linkedin.com/

https://marketing.hackerrank.com/

https://www.glassdoor.com/index.htm

Facebook groups for web developers, freelancing, remote work, etc.

Portfolio / Code Sharing / Source Control:

https://github.com/



Part 5: Other types of jobs you can work with (remotely) - with/without coding experience

SEO (Search Engine Optimization)

Translations (Spanish/Portuguese, etc.)

Affiliate Marketing (look into Clickbank.com - and use Facebook Ads to promote products)

Design (web design, photo design, etc.)

Copywriting (write sales letters for companies)

Database manager (monitor and administrate a company's database)

YouTube - make YouTube videos to gain views. Views = Money.

Dropshipping (use Shopify.com for example) and sell products in a webshop. Benefit with dropshipping is that you don't personally store the products.

Customer support

more...? Banking, economics, etc.



You can find information about all of the things I have mentioned by using YouTube or Google search.

Hope it helps.



And I hope that in 1 year, there will be at least some new web developers in Brazil, Venezuela and other countries in South America.

BlockMesh- The next 100X project- Great tech and big advisors - Marketcap < $50k

Let's first talk about MESH technology:
It works in a decentralized manner relaying messages to other nodes without a central coordinating server or node. So for example a phone could send a message offline and it would get bounced between other phones to it's final destination.
Blockmesh has patented technology, a released app as well as they just announced Mr Shrem from the original Bitcoin foundation on the board. They have pretty hard working team. They said they will start marketing soon.

What is BlockMesh
BlockMesh’s vision is to create the world's first decentralized, cost-free communications network.
All data sent through our network will be absolutely cost-free. Our goal is to become the leaders in mesh technology by reinvesting in the technology and creating a platform where any developer can take advantage of our network with our simple open source API.

BlockMesh platform has three major products
Mesh Dev
MeshDev is a platform built for developers which will enable them to add the mesh networking infrastructure we’ve developed to their current apps/platforms. Thus enabling cost-free data transfeapp use for their users.
Mesh Ex
MeshEX are our custom Wi-Fi routers which users will be able to install in their homes or offices. They will be rewarded with Mesh Tokens for each MB of data that passes through their router. This not only extends the mesh network, but pays its owner to use it.
Mesh Ad
MeshAD is a revolutionary take on real-world advertising. Knowing what your audience is interested in, and what they engage with is of utmost importance. Our advertising platform will offer partners the most targeted geo-located and demographic insights ever acquired.

Their new chat app is LIVE
https://twitter.com/blockmesh_io/status/1261029954919313410

They have patents on their HARDWARE, they are integrating their hardware ALREADY called Mesh Extender Key Ring
BlockMesh will compete globally for the peer-to-peer offline communications and remittance market. We’re building a network to support the internet of things in a race for network coverage (predicted that will connect 50 billion IOT devices by 2020.)
The MESH Extender (Experimental Stage technology) will extend the mesh network reach of your mobile device. Our initial focus for the Mesh Extenders (MeshEx) will be on communication as it’ll allow us to grow an organic, supported network.
BlockMesh is focused on delivering free communication to the undeserved and will incentive's the network with BMH tokens. We believe this approach will fast track mass deployment of devices that will rival existing platforms competing for this market segment.
For more details:
https://blockmesh.io/Hardware.php

Binance is trying VERY hard to break into the African market (1.2 BILLION PEOPLE). They are trying to convert the “Unbanked” into crypto users. What better way than to offer a South African (hotspot for crypto) cryptocurrency? I think Boshmesh has better chance to hit african market.

Advisors:
Mike Weetman Former CFO of Yahoo and DreamWorks USA
Charlie Shrem - Crypto well known figure
Few more you can find in their website

I think this project defiantly have chance to moonshot. Just sitting at $50K marketcap.
This project has potential to reach 50-100 marketcap in bull run easily which is 1000-2000X from now
5M marketcap would puts us 100X in short term
500k marketcap would put us 10X now??

Reviewing Rocket Pool: Why Was it Created?

Rocket Pool is an Ethereum infrastructure service. Individuals and companies wishing to earn interest on their Ether for a fixed period can use the decentralized network of Rocket Pool to participate in the staking. Exchanges, staking pools, and wallets can easily provide customers with stake verification services using the Rocket Pool API and its unique decentralized network of node operators.

Backstory

Since Ethereum was launched in 2015, it has been widely used in the crypto-world. And although it may have been in the shadow of Bitcoin for a long time, Ethereum 2.0 — the current update of the network — will enable the transition from Proof-of-Work to Proof-of-Stake algorithm.
Casper is the planned Ethereum network update that will move the blockchain from the PoW to PoS. Miners will be replaced by validators. The work of validators will not require hardware calculations — instead, it will be necessary to have a certain amount (steak) of coins on a special deposit.
The founders of Ethereum have repeatedly pointed out the undesirability of the emergence of large pools of validators, as this reduces the degree of decentralization of the system. However, the probability of assigning a validator to a block is weighted by the size of its deposit. So, large players may have additional votes in Ethereum development.

What is Rocket Pool?

Australian startup Rocket Pool has developed a validator pool platform that will allow Ether holders to earn with a deposit of 1 ETH instead of declared 32 ETH on the Beacon chain. Or just 16 ETH for a node operator. The minimum stake amount will vary, depending on the price of ETH.
Four other features of the Rocket Pool that may be attractive to users:
  1. Casper requires validators to be technically proficient at running an Ethereum node 24/7 and keeping that node online and secure. Rocket Pool takes care of this part by offering simple interfaces.
  2. The possibility of early withdrawal: validators do not have such an opportunity. Rocket Pool allows you to withdraw funds ahead of schedule in native rETH tokens with a commission of 5%. These tokens can be sold on the market.
  3. The user should know how to interact with smart contracts while registering with the Beacon chain. Rocket Pool undertakes the fulfillment of all interactions with Beacon chain contracts for the user.
  4. The Beacon chain will penalize users who make a deposit but cannot maintain their node on the network. The Rocket Pool uses a unique method called “chinking”, which significantly reduces the storage risk by distributing one storage across a decentralized network of nodes.

Key principles of the Rocket Pool

The process of transferring Ether from a user's wallet to a Casper stake consists of three steps:
  1. A user creates an ETH deposit on a smart contract and selects its term using a simple web application. Minimum 1 ETH, valid for 3, 6, or 12 months.
  2. Smart contracts “pack” ether into mini-pools with the same duration and integrate them into “smart nodes” that have technical resources (server, CPU, memory, bandwidth) as soon as they satisfy the minimum amount set by the protocol.
  3. Smart nodes make stakes on Casper, receive rewards for work, and distribute it. The system charges a fee, the amount of which depends on many factors, for example, the price of ETH, network reward, type of equipment, and the optimal number of mini-pools per node.

Rocket Pool Economic Model

The Rocket Pool economy consists of two types of tokens:
Rocket Pool Token (RPL) — is the protocol token that underlies the entire pool system. 18 million RPLs were sold at ICOs at the end of 2017. Its main function is to demonstrate to the whole network what deposit this smart node can count on — it should contain as many RPLs as this node can use in the rate, taking into account its technical characteristics (CPU, SSD, memory, network speed). In the future, a third-party hosting professional can become a smart node operator. The current price per RPL token is about $2.29.
Rocket Pool Beacon Chain ETH Token (rETH) enables deposits, staking rewards are paid out as rETH in order to give node operators and stakers liquidity before Serenity Phase 2.
An rETH:ETH pair can also be available during the integration with other token markets such as those on Uniswap. Thus, the users who withdraw on Rocket Pool can have their withdrawal converted to actual ETH if liquidity for the rETH pair on Uniswap is acceptable.
Of course, it’s up to you to decide whether to use it or not. Our responsibility is to keep you informed.

Reviewing Rocket Pool: Why Was it Created?

Rocket Pool is an Ethereum infrastructure service. Individuals and companies wishing to earn interest on their Ether for a fixed period can use the decentralized network of Rocket Pool to participate in the staking. Exchanges, staking pools, and wallets can easily provide customers with stake verification services using the Rocket Pool API and its unique decentralized network of node operators.

Backstory

Since Ethereum was launched in 2015, it has been widely used in the crypto-world. And although it may have been in the shadow of Bitcoin for a long time, Ethereum 2.0 — the current update of the network — will enable the transition from Proof-of-Work to Proof-of-Stake algorithm.
Casper is the planned Ethereum network update that will move the blockchain from the PoW to PoS. Miners will be replaced by validators. The work of validators will not require hardware calculations — instead, it will be necessary to have a certain amount (steak) of coins on a special deposit.
The founders of Ethereum have repeatedly pointed out the undesirability of the emergence of large pools of validators, as this reduces the degree of decentralization of the system. However, the probability of assigning a validator to a block is weighted by the size of its deposit. So, large players may have additional votes in Ethereum development.

What is Rocket Pool?

Australian startup Rocket Pool has developed a validator pool platform that will allow Ether holders to earn with a deposit of 1 ETH instead of declared 32 ETH on the Beacon chain. Or just 16 ETH for a node operator. The minimum stake amount will vary, depending on the price of ETH.
Four other features of the Rocket Pool that may be attractive to users:
  1. Casper requires validators to be technically proficient at running an Ethereum node 24/7 and keeping that node online and secure. Rocket Pool takes care of this part by offering simple interfaces.
  2. The possibility of early withdrawal: validators do not have such an opportunity. Rocket Pool allows you to withdraw funds ahead of schedule in native rETH tokens with a commission of 5%. These tokens can be sold on the market.
  3. The user should know how to interact with smart contracts while registering with the Beacon chain. Rocket Pool undertakes the fulfillment of all interactions with Beacon chain contracts for the user.
  4. The Beacon chain will penalize users who make a deposit but cannot maintain their node on the network. The Rocket Pool uses a unique method called “chinking”, which significantly reduces the storage risk by distributing one storage across a decentralized network of nodes.

Key principles of the Rocket Pool

The process of transferring Ether from a user's wallet to a Casper stake consists of three steps:
  1. A user creates an ETH deposit on a smart contract and selects its term using a simple web application. Minimum 1 ETH, valid for 3, 6, or 12 months.
  2. Smart contracts “pack” ether into mini-pools with the same duration and integrate them into “smart nodes” that have technical resources (server, CPU, memory, bandwidth) as soon as they satisfy the minimum amount set by the protocol.
  3. Smart nodes make stakes on Casper, receive rewards for work, and distribute it. The system charges a fee, the amount of which depends on many factors, for example, the price of ETH, network reward, type of equipment, and the optimal number of mini-pools per node.

Rocket Pool Economic Model

The Rocket Pool economy consists of two types of tokens:
Rocket Pool Token (RPL) — is the protocol token that underlies the entire pool system. 18 million RPLs were sold at ICOs at the end of 2017. Its main function is to demonstrate to the whole network what deposit this smart node can count on — it should contain as many RPLs as this node can use in the rate, taking into account its technical characteristics (CPU, SSD, memory, network speed). In the future, a third-party hosting professional can become a smart node operator. The current price per RPL token is about $2.29.
Rocket Pool Beacon Chain ETH Token (rETH) enables deposits, staking rewards are paid out as rETH in order to give node operators and stakers liquidity before Serenity Phase 2.
An rETH:ETH pair can also be available during the integration with other token markets such as those on Uniswap. Thus, the users who withdraw on Rocket Pool can have their withdrawal converted to actual ETH if liquidity for the rETH pair on Uniswap is acceptable.
Of course, it’s up to you to decide whether to use it or not. Our responsibility is to keep you informed.

Building Ergo: Oracles

Blockchains are siloed systems that can only reference their own data, established by consensus. Oracles are the solution to the problem of working with external information, which is vital for many everyday use cases.
Blockchains are intentionally self-contained. They reference information only recorded within their immediate ecosystem, that has been agreed upon by a majority of miners. Since the whole point of a blockchain, based on consensus, is that there are no sources of centralisation or single points of failure, that poses a problem.
What happens when you want to engage with external information? Many blockchain-based applications need to process data from the real world. That might be financial information, such as market data and prices from exchanges, for DeFi applications; it could be sporting results, for eSports predictions markets; it could even be atmospheric noise information, for random number generators.
Introducing Oracles
Oracles are the software that serves as a link between these real-world sources of data and the siloed world of the blockchain. They are simple in principle, since they only need to create a series of transactions with the necessary data (ideally formatted in an easily-accessible way) at regular intervals.
However, while anyone can record information to an open blockchain, that is a source of centralisation. So how do you trust an oracle?
The answer is: you don’t. Just like the blockchain’s consensus method itself, you need multiple oracles pulling data from multiple sources, then coming to agreement about the value to record to the blockchain. So you don’t need to trust an individual miner, and you don’t need to trust an individual oracle.
Example: bitcoin price data
As an example, let’s say we want to record bitcoin’s closing price every day to the Ergo blockchain, to give us a long-term and reliable source of price data.
We could take a dozen – or even a hundred – different data feeds, each pulling data from a major exchange. Coinbase, Bitstamp, Kraken, and so on. We make sure that many exchanges are represented, and while it’s good to have several examples of data from the same exchange, we don’t want any exchange over-represented.
Then the parties need to reach consensus about the price. Let’s say there are 100 parties and prices involved. There are different ways they could do that:
The aim is to discard or downweight any outliers, which could be due to extreme price fluctuations on a single exchange, API outages, or dishonest oracle data providers, while retaining many good data points to ensure a single reliable record of price.
Oracles are a hugely important part of the blockchain ecosystem. Once you have robust oracles in place, you can create all kinds of DeFi applications – including stablecoins, which are a vital part of the blockchain economy, and one we’ll be exploring on Ergo in the coming months.

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.

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! – 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.

Monero PHP help

I had 2 quick ques. I'm trying to use the monero PHP library to decrypt a transaction pulled from a block explorer so that I can avoid sending my private view key to 3rd parties.
use MoneroIntegrations\MoneroPhp\Cryptonote;
use MoneroIntegrations\MoneroPhp\ed25519;
require_once('Cryptonote.php');
require_once('ed25519.php');
require_once('SHA3.php');
require_once('base58.php');
require_once('Varint.php');

$cn = new Cryptonote();
$tx = json_decode(file_get_contents('https://moneroblocks.info/api/get_transaction_data/insert txid here'), true);
$extra = implode(array_map(function($x){ return str_pad(dechex($x), 2, '0', STR_PAD_LEFT); }, $tx['transaction_data']['extra']));

$derived = $cn->gen_key_derivation($cn->txpub_from_extra($extra), 'insert private view key here');

if( $cn->derive_public_key($derived, 'transaction ioutput index', 'insert public spend key here') == $tx['transaction_data']['vout'][0]['target']['key']){
`$sec1 = $cn->derivation_to_scalar($derived, 'transaction ioutput index');` `$sec2 = $cn->hash_to_scalar($sec1);` `$ec = new ed25519();` `echo bcsub($ec->decodeint(hex2bin($tx['transaction_data']['rct_signatures']['ecdhInfo'][0]['mask'])), $ec->decodeint(hex2bin($sec1)));` `echo bcsub($ec->decodeint(hex2bin($tx['transaction_data']['rct_signatures']['ecdhInfo'][0]['amount'])), $ec->decodeint(hex2bin($sec2)));` 
}

1- How are subaddresses handled? From this code so far my best guess is just looping through the public spend keys of all subaddresses but I assume that isn't correct.
2- How do I decode amounts? It seems like there's a few variations of it, I'd want to support both the 64 character long mask/amount as well as the 16 character long amount; most examples I've seen seem to be incomplete or missing portions of the code.
3- Is there a good way to sanity check the received transactions? (so we limit the 3rd party API to only possibly omitting transactions, but make sure they aren't able to send fake transactions). I'm assuming trying to validate the signatures will be impractical without just using the official client, but not sure if something simpler like Bitcoin's merkle hash validation exists.
Thanks

America is a country that's (at least theoretically) built on the idea of equality and justice quite literally for all. You had the sheer brass balls to put a big ol' statue up at one of the most trafficked entryways in the world -- yes, yes, OP's momma notwithstanding -- that literally asked the world to give you its tired, its poor, its huddled masses yearning to breathe free. You built an entire mythology around the idea that, by pulling together and with a little elbow grease, you can make something of yourself no matter where you start from.` Is it true? No, not completely -- not for a lot of people. But it *is* important. It's a hardscrabble world out there, and the idea that Americans are better because they'll do the right thing, the honourable thing, the *decent* thing no matter how hard that might be makes things a little bit brighter. It's important that the first thing countless immigrants got to see wasn't a display of America's power and strength and prosperity but of America's guidance: a torchlight in the darkness. That most mythological of figures, Superman, espouses the idea of Truth, Justice and the *American* Way for a reason. That's not because it's the way things are, but because it's the way things can be. It's something to aspire to. It's Atticus Finch and Jefferson Smith and Rocky Balboa and the Little Engine That Could. `You lose your way sometimes -- and you really, *really* do lose your way; no one should dispute that, especially given recent events -- but you're never so far gone that you can't pull your way back. America is one of very, very few countries where you always feel that that return is both possible, and something that you root for. It's the world's largest superpower that has never quite learned that it isn't the plucky underdog.` Don't let that optimism and hope for the future die out. Don't let the feeling that you can step up and change things even when the odds seem stacked against you become apathy, hate and fear. Don't be afraid to learn, to improve, to be better. I spend a *lot* of time writing about American politics, and I know full well how stressful it can be, but without hope there can be no change for the better. Improvement is aspirational, and it depends on people getting out there and choosing to try, even when it looks and feels like it makes no difference at all -- because it still does. ` If anything, that's when it matters the most -- and it's worth keeping.`

That takes me back :) - So much has happened since that first comment... I was in a pretty dark place when I started looking for laughs with this. I had just finished cleaning out my fathers house after his death... official cause of death was \"unknown due to decomposition\" and I had been tasked to clean out his house where his body had been found. It was 100+ degrees around his house when he died and he didn't have an A/C unit. His body decomposed quickly and pretty much melted into the floor. The mattress he had died on was obviously removed... and so was the floor under it... and then the dirt under the subfloor needed to be excavated... I could never get that smell of death out of my mind and had to deal with it for the 30 days while I packed up his belongings. While cleaning out his house I found 3 suicide notes in envelopes next to several empty pill bottles... also a book on different ways of committing suicide earmarked. Most of his belongings had to be tossed out as everything smelled like death... I wasn't in a good financial place and was living in an old RV parked on some abandoned property. It was in the old RV sitting at the \"kitchen table\" when this all started - and after that first comment I laughed out loud for about 10 minutes. ` Things got better for me for a while... Bitcoin went through the roof and I had managed to get my hands on a few - so when it hit 15k or so I sold them. Bought myself a good car, sold that RV, and moved into a rental house. From there life has had it's ups and downs but that was def. a low point for me when this started... a VERY low point. In a weird way the entire Undertaker thing was a way for me to laugh and smile - something I didn't do much back then. Anyway, I know most of you are expecting this end a certain way but I wanted to get serious for a minute and mention what all this means to me. Thank you all for laughing with me... it really means a lot to me. <3 - SM`

That's really sad. Like, really sad. I'm all for having hobbies and doing what you enjoy, but sitting on your ass 10 hours a day, *every day*, is downright pitiful. I love video games as much as the next person but I wish gamers would stop glorifying this kind of activity. It's not healthy nor impressive. Working 70 hours a week is extremely unhealthy, which is basically what this guy did, and he didnt even get paid.

PHP: Accessing classes -> How does '$account_info = $trading_api_sdk->doRequest(TradingApiSdkV4::METHOD_SHOW_ACCOUNT_INFO);' work?

Hi, I am trying to work with the PHP SDK (which is simply a class) from bitcoin.de (PHP SDK can be accessed here: https://codeshare.io/aJqMQn).
Bitcoin.de provides an example, which shows how to use the Sdk to return an array that contains your account info. I try to understand this example:

doRequest(TradingApiSdkV4::METHOD_SHOW_ACCOUNT_INFO); var_dump($account_info);

This is the part that I have difficulties with:

$account_info = $trading_api_sdk->doRequest(TradingApiSdkV4::METHOD_SHOW_ACCOUNT_INFO);var_dump($account_info);

Basically, I create object $trading_api_sdk from class TradingApiSdkV4. I use this object to access function doRequest(), located inside class TradingApiSdkV4. doRequest() requires two parameters (public function doRequest(string $api_method, array $parameters = [])), however, only one parameter is passed in (TradingApiSdkV4::METHOD_SHOW_ACCOUNT_INFO). This is the first thing I don't understand. How can function doRequest() be called when only 1 of 2 parameters is passed in? Furthermore, according to the class, TradingApiSdkV4::METHOD_SHOW_ACCOUNT_INFO equals 'showAccountInfo'. How does passing in 'showAccountInfo' to doRequest() yield doRequest() to return my account info? I don't get how it achieves this.
(Or is one not supposed to see how this works from the info that is provided?)Thx for any hints!

PS: thx reddit for completely shredding my formatting like five times in a row when I save the post.

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Bank Transfer Credit / Debit card Cash
Coinbase Coinbase LocalBitcoins
Gemini Bitstamp LibertyX
GDAX Bitit Mycelium LocalTrader
Bitstamp Cex.io BitQuick
Kraken CoinMama WallofCoins
Xapo BitcoinOTC
Cex.io
itBit
Bitit
Bitsquare
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy
Android Android

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
