Blockchain technology is the foundation of the Bitcoin. Blockchain implementation in election and voting. SatoshisCat. The fact that blockchain transactions are peer-to-peer, and are as such decentralized, means that they are far more secure. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree).The timestamp proves that the transaction data existed when the block was published in order to get into its hash. There is no entity to go to in the event of individuals losing private keys (or incurring losses as a result of revealing a private key). "The implementation of QR code scanning technologies in mobile applications is a pleasant and effective collaboration with Smart Engines. Source in Golang: . Each block contains its own digital fingerprint called Hash, the hash of the previous block, a timestamp .
