How Does Blockchain Technology Work?Decentralization: Blockchain technology is based on a decentralized network of computers, meaning that no single entity owns or controls the network or the data stored on it.
Instead, the network is shared among all participating members and is secured through a consensus algorithm.
Distributed Ledger: A blockchain is essentially a distributed ledger that records transactions in a secure and immutable way. All transactions are distributed across the network and stored in a public ledger, which is updated and validated with each new transaction. This allows for greater transparency and trust between users since all transactions are transparent and verifiable.
Consensus Algorithm: A consensus algorithm is used to ensure that all participants in the network agree on the current state of the ledger and to prevent double spending of digital assets. Each node on the blockchain uses a consensus algorithm to come to an agreement on the validity of new transactions. This helps to ensure the integrity of the data on the blockchain and prevents malicious actors from manipulating the system.
Miners: Miners are responsible for verifying new transactions and including them in the blockchain.
They are rewarded for their work with cryptocurrency, which incentivizes them to keep verifying transactions and maintaining the integrity of the blockchain.
Smart Contracts: Smart contracts are self-executing pieces of code that can be used to automate certain tasks on the blockchain. They can be used for a variety of applications, such as escrow services, financial transactions, and supply chain management.
