(1) data Layer
Data block: each data block generally comprises block head (Header) and block body (Body) two parts.Block
Head encapsulates current version number (Version), previous block address (Prev-block), the target cryptographic Hash of current block
(Bits), solution random number (Nonce), Merkle root (Merkle-root) and the timestamp of current block Pow common recognition process
(Timestamp) information such as.
Chain structure: current block is linked to previous block by the miner for obtaining book keeping operation power, forms newest block main chain,
Successively ring ring connects each block, a longest main chain from wound generation block to current block is formed, to have recorded block chain
The complete history of data, be capable of providing block chain data trace to the source and positioning function, arbitrary data can pass through this chain type knot
Structure is searched for by following the clues, is traced to source.
Timestamp: the equipment that block chain technical requirements obtain book keeping operation power must cover the time in active data area build
Stamp, shows the write time of block data.
Hash function: block chain does not save initial data or transaction record directly usually, but saves its hash function
Value, i.e., charge to block chain after initial data to be encoded to the character string of specific length being made of numeral and letter.
Merkle tree: Merkle tree is the important data structures of block chain, and effect is quick conclusion and verification block counts
According to existence and integrality.
Asymmetric encryption: asymmetric encryption is to be integrated into block chain to meet security requirement and ownership verifying demand
In encryption technology, common algorithms include RSA, Elgamal, Rabin, D-H, ECC (i.e. elliptic curve encryption algorithm) etc..
(2) network layer
Networking mode: the equipment of the block catenary system characteristics such as generally there is distribution, autonomy, opening can free in and out,
It is thus general to carry out the participation data that tissue spreads the whole world using peer to peer network (Peer-to-peer network, P2P network)

Magnitude equipment.
Data dissemination agreement:, will be by the device broadcasts that generate the data to other institutes of the whole network after either block data generate
Some equipment is verified.
Data authentication mechanism: each equipment moment in P2P network monitors data broadcasted in bit coin network and new
Block.After equipment receives the data that adjacent equipment is sent, the validity of the data will be first verified that.
(3) common recognition layer
Pow (Proof of Work) proof of work common recognition: in this acute hearing devised in its founder paper of bit coin
Pow common recognition mechanism, core concept are to guarantee data consistency and common recognition by introducing the calculation power competition of distributed apparatus
Safety.
Pos (Proof of Stake) equity proves common recognition mechanism: Pos common recognition is the resource to solve Pow common recognition mechanism
Waste and security flaw and proposed alternative.
DPos (Delegate Proof of Stake) share authorisation verification know together mechanism: DPos know together mechanism it is basic
Thinking is similar to " decision-making of board ", i.e., the share entitlements that each shareholder's equipment can be held in system are authorized as ballot paper
One representative obtained poll at most and is ready that " board of directors " will be entered as preceding 101 equipment represented, according to the set time
Table carries out being packaged clearing and signs and (produce) new block to transaction in turn.
(4) excitation layer
Block chain common recognition process realizes shared block chain account book by converging the calculation power resource of extensive common recognition equipment
Data verification and recording work, thus it is substantially a kind of task crowdsourcing process of equipment room of knowing together.
Issuing mechanism: the quantity of each block distribution bit coin is as time step successively decreases in bit coin system.
Distribution mechanism: in bit coin system, a large amount of small calculation power equipment would generally select that mine pond is added, by cooperating with each other
Collect and calculate power to improve " digging " and arrive the probability of new block, and shares bit coin and the service charge reward of the block.
(5) contract layer
All kinds of scripted codes, algorithm and the increasingly complex intelligence thus generated of contract layer encapsulation block catenary system are closed
If data, network and three levels of common recognition undertake respectively as block chain bottom " virtual machine ", data indicate about, data pass
