Blockchain

Blockchain is a decentralized digital ledger technology that securely records transactions across multiple computers in such a way that the registered transactions cannot be altered retroactively. This technology enables participants to have a shared and immutable record of data, promoting transparency and trust in various applications, including cryptocurrencies, supply chain management, and smart contracts. Each block in the blockchain contains a list of transactions and is linked to the previous block, forming a chain. The integrity and security of the blockchain are maintained through cryptographic techniques and consensus mechanisms, ensuring that all parties in the network agree on the validity of transactions without the need for a central authority.
