Bob The Magic Custodian



Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses.
Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes.

First, some background. Here is a summary of how custodians make us more secure:

Previously, we might give Alice our crypto assets to hold. There were risks:

But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
See - all problems are solved! All we have to worry about now is:
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are!

"On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid".
"Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since."

"As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!"
"Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?"

"Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party."
"Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!"

"What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven."
"Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!"

"We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies.
And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often".

How many holes have to exist for your funds to get stolen?
Just one.

Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so?
If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security.

The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle.

And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet?

Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds.
So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever.

Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see.
It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation.
A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.

History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance.
Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.)
Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive.

Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today.
Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well.
Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do.

[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

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.

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.

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.

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

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.
