What is blockchain and what are its functions:
1- What is blockchain?
Blockchain is a distributed accounting technology that enables secure, transparent and tamper-proof transactions. It is a shared database maintained by a network of computers and is used to record information such as financial transactions, contracts, and ownership records.
2- How does blockchain work?
Blockchain works by creating a chain of blocks, each of which contains a timestamp, a transaction and a cryptographic hash of the previous block. This makes it very difficult to manipulate the data in the blockchain, as any changes would be immediately apparent.
