Blockchain is a decentralized, digital ledger of transactions that is immutable, meaning it cannot be altered once data is added. It is a distributed database that allows multiple parties to have simultaneous access to the same information, without the need for a central authority. This makes it ideal for recording and tracking transactions, especially for applications that require transparency and security.
Nodes, or computers, validate and add transactions to a blockchain. A hash identifies and verifies each block, which contains a group of transactions. Changing a block in the chain requires changing all subsequent blocks, making it nearly impossible.
Blockchain technology has many applications, including cryptocurrencies like Bitcoin, which use blockchain to record transactions and ensure their security. It is also being explored for other uses, such as supply chain management, digital identity verification, and smart contracts. The potential for blockchain technology is vast, and it is likely to play a significant role in the future of many industries.
