Blockchain, Crypto-Currencies, Ethereum, Smart Contracts and ICOs have become the most frequently used words in computer science, FinTech and investment circles these days. Everyone likes to have skin in the game – to invest, earn/lose, re-invest and become a millionaire before anyone else would know it.
Blockchain is doing to startups & businesses (in general) and FinTech (in particular) what Email has done to Post-office mails, Mobile Phones to Landlines, Netflix to Blockbusters, Amazon to RadioShack, and what Digital pictures have done to Kodak.
It’s the era of blockchain and distributed ledger technology – it’s not the question if and when you will realize it, it is how much you lose while taking the time to come to that realization.
William Mougayar mentioned in his book Business of Blockchain there are 5,000 blockchain developers in the world (Mid-2016); compare this with 9 million Java developers and 18.5 million software developers worldwide. According to the CEO of Pantera Capital, cryptocurrencies will hit the $40 trillion market cap. ComputerWorldsays the median salary of a blockchain developer is $158,000/year and the hourly rate is $150/hour. UpWork has seen 3500% increase in blockchain skills demand over the year and according to TechCrunch there is only one candidate available for 14 blockchain jobs today. There is a job for every aspect of the blockchain ecosystem, there is a job if you know how to code smart contracts, there is a job for cryptography experts, there is a job for consensus developers, there is a job for Ripple suit of applications, and there is a job for IBM’s Hyperledger Fabric. It doesn’t matter which part of this ecosystem you work in, there is a job available (right now) for you. Portals like Blocktribe are dedicated to blockchain related jobs only. There are 5,000+ blockchain startups, and ICOs have raised close to $7 billion worldwide. The world would need half a million blockchain developers in next five years. The question is what YOU can do to secure a job and make your dreams come true, and how YOU can become someone that would qualify for these half a million jobs worldwide.
There is a lot of confusion and misrepresentation out there when it comes to defining the Blockchain, here is my very brief and simple blockchain definition that almost everyone can agree upon:
“Blockchain is a peer-to-peer decentralized distributed ledger that permanently & chronologically records and guarantees an immutable, unalterable trustworthy transaction (of money or any valuable asset) in a trust-less environment through consensus protocol secured by cryptography with economically incentivized participation.”
Blockchain is an immutable, open, secure, and transparent shared ledger that anyone voluntarily can join and leave as he will. It has two broad types: Public (with open participation incentivized and punished by consensus protocol) and Private (with a consortium or private businesses’ vetted membership and enforcement of laws and regulations in place). Compare to centralized structures blockchain saves time, removes cost, reduce risk and increase trust.
Ok, so what one can do to become a good blockchain developer if he/she cannot afford or get selected for competitive and expensive programs. What someone from a developing country can do to improve his/her chances of getting hired in this important field or even try to use these advanced skills to improve their surroundings, communities, and countries.
Here is my cheat sheet of becoming a good Blockchain Developer for (almost) Free:

No one can stop you if you like to become a blockchain developer, it will take around a year, few hundred dollars, firm commitment, a lot of patience and heavy programming practice to become one. Once you go through all or some of it, you can practice at GitCoin to see how good you can code and get paid for your work. You can also submit your profile at CrossOver and get a remote job for $100,000/year. Even if you complete half of it, send me a note and I will have something ready for you.
Ball is in your court; it does not matter where you are and how much you can afford, if you want to make at least four times higher the average income of your countrymen, this is the way to do it, at least for the next ten years.
Do not forget to check out Facebook Libra and Pi Networks. They are redefining the very notion of money as we know it.
