Blockchain Technology

Decentralized database: Instead of being stored in one location, the blockchain is stored and managed simultaneously on many computers in a network.
Chained blocks: Each transaction is recorded in a block. New blocks are added chronologically and linked to the previous block to form an immutable chain.
Forgery-proof: Because each block contains a reference to the previous one and the chain is distributed across the network, any subsequent modification of a block would be immediately detectable and the entire chain would be invalidated.
Transparency: Transactions are publicly visible.
Cryptography: Security is ensured through cryptographic techniques such as digital signatures.
