Several specific examples are provided below in conjunction with above-described embodiment:
Example 1:
This example is illustrated by taking the processing of the block chain of digital asset as an example.
The life cycle of digital asset is generally divided into three phases: distribution phase, is quit listing the stage at the circulation stage.
Distribution phase corresponding states includes: creation, is put in storage, transfers；
Circulation stage corresponding states includes: to sell, trade, exchanging；
Stage corresponding states of quitting listing includes: repurchase, destroys；
The above are the complete or collected works of digital asset life cycle state, different types of digital asset state may be the above complete or collected works
A subset part.
This example is based on block chain the relevant technologies, is saved, is recorded to digital asset life-cycle whole process, allows one
All state change tracks of assets can recall, can not distort.Using the mode of alliance's chain, in the case where portion centers,
Improve block chain execution efficiency；It allows multi-party participation to supervise, implementing result is made more to have confidence level and authority.
1. digital asset is from when being created to destruction, the track of all life cycles is visible to user.
2. digital asset has specific Relationship of Real Right in each state, and visible to user.
3. having the record that can not be distorted when the Relationship of Real Right of digital asset changes, first is seen.
4. after digital asset is destroyed, it is ensured that market circulation can not be entered back into.
The related participant of digital asset business is as follows:
Registration company is responsible for digital asset distribution phase and the destruction in delisting stage.
Exchange participates in the repurchase in digital asset circulation stage and delisting stage.
Counterparty, transaction on exchange member.
The exchange corresponds to miner's node in this example, can be used for the transaction execution business to counterparty and patrols
Volume, obtain the transaction results.
The registration company corresponds to account book node, the correlations such as can be used for creating digital asset, register, transferring the possession of
The block chain of information discloses.The counterparty can be used as the initiator of transaction, can send various requests to block chain network, ask
Ask inquiry etc..
The division of block chain node type can be as follows:
Supervisory node, to the authentication of access node；By Raft common recognition protocol algorithm, the consistency of implementing result is carried out
The confirmation of confirmation and both parties' identity；
Miner's node provides calculation power for block chain service operation, can be with to dig reward that mine obtains periodically to calculate contribution
Obtain transaction procedure expense is divided into reward.Miner's node be added in alliance's chain need it is (practical to visit by the license of supervisory node
Account for front yard tolerant system PBFT, ballot verifying node availability), prevent malicious node problem.
Account book node is responsible for saving the block data that miner's node is packaged.Same account book node coalizes the effective of chain
Property is also required to the approval by supervisory node.Block data can be continuously increased over time, allow each node all
Block data all individually storage is a, the increase that resource overhead will be with portfolio linear is incremented by.
So account book node to the operation logic of data and is stored logical separation by this example, participates in each side and oneself is provided

Row service logic.
Miner's node finally has a node to obtain book keeping operation power by competition, while passing through proof of work (Proof of
Work, PoW) proof of work mechanism, obtain certain reward.PoW mechanism is briefly exactly to do much, receives much, can rouse
It encourages participation each side and calculation power support is actively provided.
In this example, it will calculate and removed with common recognition function, common recognition function is put into supervisory node.Supervisory node
Relatively fewer, that reaches common understanding is more efficient, and supervisory node has centralized management property, has preferably safety
Property.
The implementing result of miner's node is synchronously written into block counts after the confirmation of supervisory node, by all account book nodes
In.
4. the security control of supervisory node, it may include following steps:
A. distribution or supervisory node voluntarily distribute new node mark (Identity, ID) and key (key) under line, manage journey
Sequence calls supervisory node interface that will store in ID and key write-in block.The block can be the block in supervision block chain, controlled area
Block chain is different from the assets block chain of digital asset.
B. when miner's node broadcasts implementing result to supervisory node cluster, supervisory node obtains its ID and key, with controlled area
Value in block is compared, and verifies role and the validity of node.Then common recognition ballot (example is carried out to implementing result verifying again
Such as: participating in both parties' real name effectiveness of information of digital asset transfer, the authenticity for address of transferring accounts).
C. it before all calling account book nodes obtain block data, needs to be verified to supervisory node, specifically can include:
Step C1: the ID and key of caller (corresponding to client above-mentioned) request account book node；
Step C2: account book node returns to ID and key；
Step C3: ID and key are sent to supervisory node by caller；
Step C4:ID and key are broadcasted between supervisory node；
Step C5: all supervisory nodes for receiving message verify ID and key；
Step C6: supervisory node votes to verification result validity；
Step C7: supervisory node returns to voting results to caller；
Using the Managed Solution of this exemplary digital asset Life cycle, make each shape in digital asset life cycle
Authenticity, the validity of state variation are guaranteed, the clear process control of ownership.
