Asset account ID is the block chain account that digital asset is established, for locking digital asset merchandised；Pre-
Hash is used to mark the previous transaction of the assets of current transactional operation；Nonce is asset account for marking current transaction
Which transaction；PreStatus carries out the state before currently transaction for flagged asset；CurrentStatus is for marking
Assets complete the state after current transaction；The concrete operations that Operation is used to that the transaction to be marked to carry out assets.
Step S3, other nodes in network receive Transaction Information, and the LT- of retrieval assets is encoded according to asset account
Hash, LST-hash, LCT-hash carry out analytical Calculation, with the information such as Pre-hash, nonce, preStatus of transaction into
Row comparison, verification.
Step S4, whether verification information is consistent, if inconsistent, carries out step 05, if unanimously, carrying out step S6；To transaction
The detailed process of information checking are as follows: be based on asset account State Tree, obtain and parse the nearest transaction LT- of digital asset
Hash judges whether the LT-hash is consistent with the Pre-hash in Transaction Information, if inconsistent, carries out step S5；If consistent,
The nonce value in transaction is obtained according to LT-hash, judges whether the nonce value of this transaction is equal to the nonce in LT-hash
Value plus 1 carries out step S5 if inconsistent；If consistent, the LST-hash of asset account State Tree, judgement and Transaction Information are parsed
In preStatus it is whether consistent, if inconsistent, carry out step S5, if unanimously, the legitimacy verifies of Transaction Information pass through,
Carry out step S6.
Step S5, verification do not pass through, and return to error message, false transaction is abandoned.
Step S6 judges whether to need to be verified for transaction chain information, if then carrying out step S7, otherwise carries out step
S9.Chain transaction Information Authentication whether is carried out to determine according to intelligent contract rule, digital asset binds intelligent contract in distribution,
The intelligence contract is associated with specific business scenario, is stated the transformation rule between the basic status and each state of assets, is based on
The handling function etc. of state transition rules statement assets.
Step S7 obtains transaction chain information and is verified, according to the LT-hash of the asset account newest transaction obtained
Pre-hash obtains the previous transaction of assets, successively navigates to the historical trading of asset account forward, obtains transaction chain information
It is verified.
Step S8, whether verifying transaction chain information is consistent, if inconsistent, carries out step S5, if unanimously, carrying out step S9.
Illustrate and verify to transaction chain information: this operation is checked in authorization, it is assumed that intelligent contract regulation only allows user to check
Once, check once-through operation, when user wants to check, will be first based on the chain transaction Information Authentication operation as primary transaction
It is no to have executed, if being not carried out, it is believed that verification passes through, and transaction is correct.
Step S9, trade correct update AMPTC, concrete operations are as follows: more New Transaction asset account LT-hash is directed toward new hand over
Easily, it if New Transaction makes Asset State change, updates LST-hash and is directed toward New Transaction, if New Transaction becomes asset content
Change, updates LCT-hash and be directed toward New Transaction；Block is added in licit traffic, merkle root is calculated and is stored in block head.
Step S10 broadcasts new block into network, the synchronous block of the node in network.
The above is the preferred embodiment of the present invention, for those skilled in the art, In
