Blockchain technology is an open-source digital record book that securely and transparently records transactions and data across a network of computers.
It boasts various vital components that make it stand out as a revolution. These components include:
- Decentralized Network: A blockchain infrastructure consists of a network of computers (aka nodes) that work together to validate and record transactions.
- Blocks: A block is a collection of transactions on a blockchain network. It’s a container that holds multiple transactions, similar to a page in a ledger book.
A list of transactions or metadata within a block, such as “Person A sent ten units of cryptocurrency to Person B,” is embedded.
They are created through mining (in proof-of-work blockchains) or validation (in proof-of-stake blockchains) to collect or verify transactions from the network.
- Chain: This is a sequence of blocks, with each chain containing a unique code (i.e., hash) connecting it to the previous block.
- Cryptography uses advanced math and algorithms to secure transactions and control access.
- Consensus Mechanisms are the algorithms various blockchains use to achieve agreement among nodes on the system’s state.
Consensus mechanisms certify that all nodes agree on the validity of transactions, blocks, or other data, ensuring the network’s integrity and consistency.
Examples include Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Stake (DPoS), and Leader-Based Consensus.
Note: According to a report by Fortune Business Insights, the blockchain market is expected to experience remarkable growth, increasing from $24.8 billion in 2024 to $825.9 billion by 20302, with a CAGR of 52.8%.
Its evolution began in January 2009 when Satoshi Nakamoto introduced Bitcoin, the first decentralized cryptocurrency, using blockchain technology.
Although there were many theories about what the Bitcoin blockchain could do, it wasn’t until 2010 that early adoption and experimentation began with the emergence of other cryptocurrencies (altcoins) like Litecoin, Namecoin, Pearcoin, etc.
These altcoins sought to improve on the deficiencies of Bitcoin, having different use cases and consensus mechanisms other than that of Bitcoin.
Also, initial coin offerings (ICOs) have become immensely famous for funding blockchain projects.
Note: Initial Coin Offering (ICO) is a method blockchain-based projects use to raise capital by issuing and selling their cryptocurrency tokens to investors.
By 2014, Ethereum was launched by Vitalik Buterin and a team of blockchain innovators.
The launch of Ethereum introduced smart contracts (autonomous contracts with their terms of the agreement written directly into lines of code) into the blockchain ecosystem, thereby allowing the creation of various DeFi projects in the crypto space.
Also, in 2014, companies like Walmart and JPMorgan began exploring private blockchains, such as Bloq, Blockstream, etc., for supply chain management, identity verification, and more.
Unlike Ethereum and Bitcoin, these private blockchain networks offered more control and scalability.
By 2016, Hyperledger and interoperability solutions will enable seamless interactions between different blockchain networks.
Note: Hyperledger is a project that acts like a toolkit that provides the building blocks for companies to create their blockchain systems while helping businesses use blockchain technology)
By 2017, ICOs had reached an all-time high. Numerous blockchain projects were funded, and cryptocurrency prices surged, attracting mainstream attention.
Governments and institutions began providing regulatory frameworks and investing in blockchain technology. At the same time, Security Token Offerings (STOs) emerged as a more regulated alternative to ICOs.
2020 ushered the world into the Decentralized Finance (DeFi) and Non-Fungible Tokens (NFTs) revolution. DeFi applications like Uniswap and Compound (created primarily for lending, borrowing, and trading) are gaining popularity on Ethereum. Meanwhile, NFTs, unique digital assets, are becoming increasingly popular in art, collectibles, real estate, fashion, and more.
