What is blockchain?
Blockchain is a digital ledger that records transactions across multiple information systems. Everyone can access it, but its structure prevents unauthorized modifications or fraudulent entries. Each entry is a tamper-proof record or "block" of information connected to the previous transaction by a complex string of numbers called a cryptographic hash.
Knowing how to work with blockchain can open up a variety of positions for you in security and contracts. As more industries begin to use blockchain to verify products and agreements, blockchain skills may translate to more job opportunities.
Why should you learn blockchain?
Blockchain development isn't just a record of cryptocurrency transactions — it's also a transformative method of storing anonymous data. As the technology progresses and people find new uses for it, more businesses will likely adopt some form of blockchain security. Therefore, blockchain skills may qualify you for increasingly essential roles.
Other benefits of learning blockchain include:
- Gaining worldwide skills: Blockchains are decentralized, meaning they operate through networks worldwide. Learning blockchain may lead to global opportunities.
- Creating a flexible career: Many industries, such as supply chain management, healthcare, and finance, use blockchain technology, making the skill highly transferable.
- Becoming an innovator: Blockchain technology is a fairly recent invention with many capabilities for discovery. Learning blockchain can help you innovate tech spaces.
How to get started in blockchain technology
1. Learn front-end development
Your journey to learning blockchain technology may begin with front-end development. Front-end development involves coding the part of a website that the user interacts with, including UI, UX, and page elements.
Many people begin learning blockchain with front-end development because coding languages like CSS, Javascript, and HTML are instrumental in communicating with the blockchain. Once you understand general coding languages, you can explore Solidity, the primary language for smart contracts.
Dive into the basics of computer science with Harvard CS50 on edX to learn about front-end development and other computer science basics.
2. Understand smart contract anatomy
Using blockchain technology requires an understanding of smart contract anatomy. This code automates the algorithms necessary for immediate approvals of changes to the blockchain.
Smart contracts run the input data through an algorithm that assesses its qualities. If the input meets certain qualifications, each blockchain member has a smart contract that approves the data, and the blockchain will change accordingly. The approval process, along with cryptographic hashing, is what makes blockchain technology so secure.
3. Set up a blockchain and deploy smart contracts
Blockchain involves many processes that make it anonymous and secure. These essential processes include:
- Oracles: Oracle networks are third-party programs that enable communication between blockchain and the real world.
- Security: Learn the standard practices, like fuzz-testing and time-tested tools like Manticore, that can help you keep your blockchain technology secure.
- Management: Management platforms like Ethereum, IBM Blockchain, and OpenZeppelin offer frameworks for operating blockchain applications and technology.
After developing each process, you can upload it to a control system and hosting service and test the code.
