- Python blockchain project practice: build your own blockchain application step by step
- 1. What is blockchain? Blockchain is a distributed ledger technology that allows multiple participants to securely record and share data without a central authority. A blockchain consists of a series of blocks, each of which contains a set of transactions and related information such as timestamps, hashes, and the hash of the previous block. When a new block is added to the blockchain, it is permanently stored in the ledger of all participants and cannot be tampered with. 2. How does blockchain work? Transactions on the blockchain are verified by miners. Miners use powerful computers to solve complex mathematical problems to verify transactions and add them to the blockchain. After miners successfully solve a puzzle, they are rewarded. This reward is usually a cryptocurrency such as Bitcoin or Ethereum. 3. Applications of Blockchain Blockchain
