How To Become A Blockchain Developer From Scratch! 🚀
Cryptonomic is a word that is a mix of Cryptocurrency and Economics. Cryptocurrencies are affected by the valuation of currency and many monetary policies.
One can also learn about the game theory to be more explicit about the working of cryptocurrency in the market and its valuation. It will help one to understand how cryptocurrencies are kept in check without being monitored by any central bank. An individual should learn how the economic structure is working around the cryptocurrency. The smart contracts are the programs which help in automating the transactions. It helps in increasing the capabilities of Blockchain without any need of middlemen or lawyers to settle the deal.
The smarts contracts are made with specific conditions or in particular situations. When these particular situations or conditions are met, then the transaction will be automatically processed when required. Currently, Auditing and optimizing of smart contracts cannot be done by many developers.
A developer should be very well aware of all possibilities of execution of a smart contract. He should be able to ensure that smart contracts are only executed when it is expected. There are some decentralized applications DApp that are built on blockchains. There are various platforms for a blockchain developer to build a DApp. Here are some of the popular Decentralized Applications:. The main goal of Hyperledger is to develop technologies in the cross-industry Blockchain using an open-source collaborative platform.
The main goal of the EOS blockchain is to support industrial-scale applications. It is a decentralized operating system that has more scalability and higher transaction speed such as Ethereum. NEO is not limited to one language, unlike Ethereum. It will work as a platform for digital businesses in the future. In , Vitalik Buterin created Ethereum, which is currently the most popular platform for development.
The Ethereum is fueled by the cryptocurrency called Ether. The language used in the Ethereum is called Solidity. Solidity is a smart-contract oriented language. A blockchain developer should be able to innovate using the design thinking methodology. Blockchain is used to simplify the processes in the business, which helps in driving outcomes of companies.
A developer in Blockchain should have security skills like elliptic curve digital signatures, Merkle proofs, cryptographic hashing, private key, and public-key cryptography and many more. Frameworks in security are getting evolved for regulatory needs, legal needs, and compliance needs.
There are multiple frameworks in Blockchain and learning all of them can create confusion. One should know how to select the right blockchain platform for particular cases. Different blockchain platforms such as R3 Corda, Ripple, Ethereum, Hyperledger Fabric are some of the excellent blockchain platforms that a beginner can start to learn about.
A developer should be an expert to build distributed ledger technology. It will help in accelerating the development of smart contracts. The mindset of blockchain developers should be open source because there is a risk of deployment in various technology platforms of interconnecting ledgers.
Business outcomes can be driven, and latency is reduced by integrating with systems of an enterprise. During the formation of the consortium, skills of negotiation and collaboration are critical. Blockchain as a Service is a new latest thing in the market that a blockchain developer should be able to take benefits from.
A developer needs to understand the result expected by a business. One should build direct connections and explore data flow between customers, suppliers and trading partners across the ecosystem. As we can see how the Blockchain has grown so much in just a few years, no one can deny that the Blockchain is the best technology that many industries will be based on in the future.
The skills required to become a blockchain developer ranges from understanding technical knowledge to study fundamentals of working of cryptocurrency and blockchain structures. Cryptography is the namesake and bedrock of cryptocurrencies. The other important cryptographic primitive is the cryptographic hash function.
These can be used to construct commitment schemes , and are the building block for Merkle trees. Merkle trees enable Merkle proofs , one of the key optimizations that blockchains use for scalability. Distributed systems are absolutely essential to reasoning about blockchains, so you must build a foundation here before tackling blockchain programming.
Know the difficulties of reasoning about time in a distributed system. Appreciate the tradeoffs between safety and liveness. PBFT is the basis for many non-proof-of-work blockchain consensus algorithms. Learn about sharding such as via consistent hashing , leader-follower replication , and quorum-based commits.
The decentralization of blockchains derives in large part from their peer-to-peer network topology. As such, blockchains are direct descendants of the past P2P networks. To understand the blockchain communication model, you need to understand the basics of computer networking : this means understanding TCP vs UDP , the packet model, what IP packets look like , and roughly how Internet routing works.
Public blockchains tend to spread messages via gossip protocols using flooding. Blockchains have their own place, but they draw upon the lessons of these networks and how they were designed. Cryptocurrencies are inherently multidisciplinary — this is part of what makes them so fascinating and radical. Besides computer science, cryptography, and networking, they are also deeply interwoven with economics.
Cryptocurrencies can derive many security properties through their economic structures, which is often termed cryptoeconomics. As such, economics is essential to understanding cryptocurrencies. The most important branch of economics that plays into cryptocurrencies is game theory , the study of payoffs and incentives among multiple agents. Two key concepts in your repertoire should be Nash equilibria and Schelling points , as they feature prominently in cryptoeconomic analysis.
Cryptocurrencies are not just protocols, they are also forms of money. As such, they respond to the laws of macroeconomics if they can be called laws. Cryptocurrencies are subject to different monetary policies , and respond predictably to inflation and deflation.
You should understand these processes and the effects they have on spending, saving, etc. Another valuable economic concept is the velocity of money , especially as it corresponds to valuing a currency. Cryptocurrencies are also deeply interwoven with markets, which requires an understanding of microeconomics.
For many coin distributions and cryptoeconomic systems, auction theory features prominently. If you are, feel free to skim or skip over them entirely.
In October of , Satoshi Nakamoto published a white paper in which he described a protocol for a decentralized digital currency. He called this protocol Bitcoin. First, I recommend building your intuitions about proof-of-work and the fork choice rule also known as Nakamoto consensus. Start here:. Here are some good resources. Source and slides here. There are also other blockchain implementations you can find, written in various programming languages.
You should also by now have enough background that you should be able to read and understand the original Bitcoin whitepaper. To understand the economics and mechanics of Bitcoin mining, I recommend watching the lecture on Bitcoin mining in the Bitcoin and Cryptocurrencies Princeton course. You should also be able to play around with a Bitcoin block explorer and navigate raw Bitcoin transactions.
Now is a good time to study up on the history of Bitcoin and cryptocurrencies. The below video, offered by a UC Berkeley Decal, gives a good overview. You understand how blockchains and proof-of-work can achieve distributed, Byzantine fault-tolerant consensus within a peer-to-peer network. But a payments network is just one application you can run atop such a blockchain.
In , Vitalik Buterin, the creator of Ethereum asked: what if you used a blockchain to implement a decentralized computer? In Ethereum, you pay miners to execute your programs on this distributed virtual machine. This means you can perform arbitrary computations, using a Turing-complete programming language unlike Bitcoin script. This brings us to smart contracts — the name for programs that run on such a virtual machine.
In other words, you can create financial contracts that automatically enforce themselves. Ethereum has enabled the wave of ICOs and developers building atop the blockchain. It is the second largest cryptocurrency behind Bitcoin, it has more than 10x the developers of the next most popular platform, it has the strongest developer team, the most mature tooling, and the majority of ICOs and projects atop it. It also has the most industry support , which goes a long way.
The ideas behind Ethereum have also spawned a wave of innovation in cryptoeconomics. You should dip your toes into the ideas around DAOs , and all of the sci-fi fever dreams that they hint at. As with any technology, the best way to get acquainted with Ethereum is by building a few small projects. The dominant programming language for Ethereum is Solidity, which is a statically typed JavaScript-esque language.
To get your first exposure to Solidity development, I recommend working through all of the CryptoZombies tutorial.
I recommend this guide as a first tutorial to walk you through the process. This tutorial does a good job of walking you through an end-to-end blockchain stack and explaining the pieces as they go along.
Karl Floersch has a great tutorial where he walks through how to build a secure commit-reveal voting system. Great, now for your mid-term exam: build a secure coin toss game, where two players can securely bet on the coin flip. No tutorial this time, do it on your own.
Think about possible attacks — how can the players cheat? Can you ensure that they play honestly? Here are some hints.
Security is absolutely essential to blockchain development. Smart contracts have been plagued by disastrous hacks, including the DAO hack , the Parity Wallet hack , and the affectionately named Parity Wallet hack 2 now with its own T-shirt.
The truth is, smart contracts are extremely hard to get right. Though the programming toolchain will improve to make these exact attacks harder, they were ultimately all due to programmer error.
There are also many subtler bugs that arise from smart contract programming, such as in frontrunning or secure generation of randomness. As a smart contract developer, you must treat security as paramount. That means any code that handles significant flows of money should be run through static analyzers like Oyente or Securify , tested thoroughly, and then audited by an experienced smart contract auditor. To strengthen your security chops, I recommend working through The Ethernaut by OpenZeppelin, a game where you find and attack vulnerabilities in smart contracts.
Many of them have you replicate real attacks against smart contracts that have occurred in the wild. Phil Daian also has an excellent set of smart contract hacking challenges called Hack This Contract. Expect to revisit this document many times over in your smart contract programming career. The bibliography is also worth exploring for further reading by security experts. Most developers recommend VSCode or Atom for your text editor, since they have decent Solidity plugins.
Now is a good time to look into IPFS , which you can use as a fully decentralized filestore at much cheaper cost than the Ethereum blockchain. Once you have your full Web3 stack set up, try deploying an end-to-end Dapp decentralized application. This tutorial provides a nice full-stack overview using Node and Postgres for the backend, and this tutorial will show you how to create a fully decentralized application, using IPFS as your persistence layer.
First, start building your own projects. OpenZeppelin might be a good place to start for smart contracts. Get on their Slack or Rocketchat — the devs are usually readily accessible.
Beyond open source contributions, there are also many blockchain hackathons constantly popping up. Wherever it is, find your people and continue learning. The best way to really understand the blockchain world is to immerse yourself in it. The three fantastic podcasts I recommend are the Software Engineering Daily Blockchain interviews , which provide good technical intros to many topics and cryptocurrencies.
Another interesting up-and-coming technical podcast is Conspiratus. Subscribe to the Ethereum Foundation and watch Devcon3 presentations. Blockchain at Berkeley records many of their lectures, most of which are excellent technical overviews. Decypher Media also posts talks, whitepaper reviews, and tutorials. Jackson Palmer has engaging weekly overviews, these are on the less technical side but very evenly presented.
