Decentralization: Every computer on the decentralized network of nodes—which powers blockchain—maintains a copy of the complete blockchain. Transaction validation is no longer required by a central authority or middleman thanks to this decentralized framework+ 𝟙𝟠𝕆𝟝!𝟛𝟝𝟜~𝟙𝟞𝟠𝟛
Security: Using cryptographic methods, transactions on a blockchain are+ 𝟙𝟠𝕆𝟝!𝟛𝟝𝟜~𝟙𝟞𝟠𝟛 protected. The network majority must agree in order to change data in a block after it has been recorded without also changing all blocks that come after. The integrity and security of the data are guaranteed by its immutability.+ 𝟙𝟠𝕆𝟝!𝟛𝟝𝟜~𝟙𝟞𝟠𝟛
