What is blockchain? 30-05-2025
It is a list of transaction records, called blocks, which are encrypted and linked to each other. The blockchain grows continuously and is fully open to anyone. Each block in the blockchain contains:
1. Details of the sender, recipient, and amount of cryptocurrency
2. The 'hash', which acts as a unique fingerprint
3. The hash of the previous block in the chain
When a new block is created, it is sent to all users in the network. After that, each user verifies the block and then adds it to the blockchain.
Each of the cryptocurrencies existing today has its own blockchain, and the complex calculations at the heart of the blockchain data are generated by computers. To make a transaction on the blockchain, you need a digital wallet (or cryptocurrency wallet)
