Block chain (Block Chain) technology is a kind of emerging technology occurred in recent years in information technology field.It is unique
Decentralization, information can not distort, multinode collective maintainability, publicity, the attributes such as secret protection so that block chain technology
It is able to record in being based on incredible internet and believable trading information data is provided.
Block chain technology is decentralization and data storage, transmission and the method proved for residing in distributed frame, uses area
Block (Block) can replace dependence of the current internet to central server, such as all data can be made to change or hand over
Easy project is all recorded on a cloud system, and theoretically realizing in data transmission self proves data.
Each block is one and is comprised in the container data structures for having polymerize data in block chain, it includes member by one
The a lot of transaction composition of the block head of data and composition block main body immediately after.Block specifically includes: block size word
Section, usually 4 bytes；Block head file, usually 80 bytes；Transaction counter field, generally 1-9 byte, note
Record number of transaction；Transaction field, usually variable-length, records Transaction Details.
Block head is made of three group metadatas, is the data of one group of reference father's block cryptographic Hash first, this group metadata is used
In the block is connected with the previous block in block chain.Second group metadata includes difficulty, timestamp and only uses primary
Number (Number used once, referred to as " Nonce ").Third element data are Mei Keer (Merkle) several (a kind of
For effectively summarizing the data structure of All Activity in block).For example, block head may include following field: (1) version word
Section, usually 4 byte；(2) father's block Hash value field, usually 32 byte, for quoting the Hash of father's block in block chain
Value；(3) Merkle root field, for recording the cryptographic Hash for the Merkle tree root traded in the block；(4) timestamp field is led to
It is often 4 fields, the time proximity generated for identifying block is accurate to the second；(5) Nonce field is calculated for proof of work
The counter of method.
Each block can quote previous block by " the father's block Hash value field " of its block head.Namely
It says, each block head includes the cryptographic Hash of its father's block.And only one father's block of each block, but can be interim
There are multiple sub-blocks.There is the case where multiple sub-blocks referred to as " block chain bifurcated " in one block.Block chain bifurcated indicates one
Transition condition, only one final sub-block can become a part of block chain.
Block chain is the data structure being orderly chained up from back to front by block, and each block all points to previous area
Block.It can be stored as a kind of file comprising non-relativeness record, or be stored in a simple database.It can
To regard block chain as a storehouse, block chain height means that the distance between block and first block and top or top
Indicate newest block.Each block head is encrypted (for example, secure hash algorithm (Secure Hash Algorithm,
Referred to as " SHA ")), produce a cryptographic Hash.The correspondence block in block chain can be identified by this cryptographic Hash.
Block chain can be typically divided between publicly-owned chain, alliance's chain and privately owned chain according to access authority.Publicly-owned chain refers to any
People can access according to agreement and participate in the block chain of common recognition；Alliance's chain refers to that its common recognition process is controlled by preselected node
Block chain；During privately owned chain refers to that all permissions are all organized at one, and by the block chain of any control of the tissue.
For entire block chain network, need target to be achieved be all devices agree to jointly some information and by it more
Newly into total shared account book.For this purpose, introducing common recognition mechanism in block chain network, two kinds of typical algorithms are in common recognition mechanism
Proof of work and equity prove.The essence of proof of work (Proof Of Work, referred to as " PoW ") is for information transmitting
Cost is added, reduces the rate of information transmission, and a random element is added and guarantees that only one equipment can in a period
Information broadcast is carried out to have the right.This random element is exactly that equipment is allowed to go to calculate a random Harsh value.Particularly as being that block is set
The standby input data according to acquisition, be calculated a string 64 random digit and letter character string, but only met
The equipment for the cryptographic Hash that cryptographic Hash requires can be received to be proof of work by block chain network.And the Hash of proof of work
Algorithm is also by way of the input value of hash algorithm next time, realizing history for the information in each newborn block
The series connection of information forms retrospective chain (block chain).
Intelligent contract is stored in one section of executable code in block chain (or a certain block chain node in block chain), this
The execution condition and business processing logic that intelligent contract is defined in section executable code define and start intelligent contract
Condition and the intelligence contract starting after how to handle receive business processing request.In general, intelligent contract is compiled by user
It finishes writing and is published to after block chain, just can not be edited or be modified again.For example, the execution operation of intelligent contract can basis
Event is triggered.For example, the execution of intelligent contract can be registered as a transaction on block chain, and it is recorded in block chain
In.
Intelligent contract is a kind of contract that record clause is removed with computer language substitution legal language, may be regarded as one section of deployment
Program on block chain has and self executes and self mandatory attribute.It self executes and refers to contract automatic running after deployment
It comes into force；It self forces to refer to that participant can call contract to enforce it in the case where meeting condition.Entire decision process
It does not need believable third party and participates in arbitration intervention.By block chain technology guarantee data authentic and valid and intelligent contract can not
Tamper, and intelligent contract is responsible for enforcing specification, so that the application demand that block chain technical characteristic and charging pile are shared has
