introductory Blockchain must-read what the blockchain is. "Blockchain" technology was originally designed by an alias Satoshi for Bitcoin (a digital currency) and a special database technology, it is based on the cryptographic Elliptic Curve Digital Signature Algorithm (ECDSA) to achieve the central to the design of the peer system.
