The concept of block chain or blockchain Blockchain

#

Blockchain is an open source, programmable, uncontrollable technology that is essentially a digital record book of transactions that are replicated and distributed across the entire network of the system in blocks of encrypted records, each of which is a phrase.About a block, which is linked to each other and secured with a special cryptography code. Each block contains a hash, which is a mathematical algorithm that records a small portion of the data related to the transactions included in the record as a whole, and is encrypted with a partial code of the overall code with which the chain of blocks is encrypted. For the total record of transactions and blocks, the decentralized database managed by many participants - as happens in Blockchain - is known as Distributed Ledger Technology (DLT).
