We already know that Bitcoin is the equivalent of a "global account book," and how this bill is stored. In other words, where to put the account.
The blockchain contains n sorted blocks of time, each of which has a pointer to the previous chunk, and all blocks form a chain through the pointer, so called a blockchain. The first block is called the Genesis block,

What the blockchain really is.
Blockchain (English: Blockchain) is a distributed database, originated from Bitcoin, Blockchain is a series of cryptographic methods associated with the generated data block, each block contains a number of Bitcoin network transactions information, to verify the validi

Blockchain Introduction
A blockchain is a data structure that is logically linked from the back to the block that contains the transaction information. It can be stored as flat file, which contains files with no relative relational records, or stored in a simple database. Bitcoin core clients use Google's LEVELDB database to store blockchain metadata. Chunks are

The blockchain uses an Internet-based (Internet)-on-Peer (peer-to-peer) network architecture. Peer to peer refers to each computer located in the same network is equal to each other, each node provides network services together, there is no "special" node. Each network node is connected with a "flat (flat)" topology. There is no service-side (server), centralized service,
