Currently, digital assets are mostly based on public, alliance chain foundings and releases. Public chain-based digital assets during a transaction, the credentialing of the digital assets is accomplished through a distributed ledger of the public chain, and the transaction value of the digital assets is accomplished through a virtual token on another blockchain ledger, such as an ethernet currency, a bitcoin, etc., or its value exchange is accomplished directly through a legal currency, such as renminbi, dollars, euros, etc. The virtual token is not usually the same as the chain in which the digital asset is located, or legal currency is generated by a third party casting, so that in the transaction process of the digital asset, a third party platform is required to be used as a connection to realize information exchange of two distributed accounts, or the transaction of the digital asset based on the legal currency is required to be realized. When the trading of the digital assets is realized through the virtual token or legal currency of the different chains in the alliance chain, the virtual token generated on one blockchain is used for representing the value of the digital assets casted on the other blockchain, and the problem of unstable value of the digital assets is brought essentially, so that the trading risk is brought to the trading of the digital assets, and meanwhile, the trading efficiency of the digital assets is also negatively influenced.
Therefore, how to reduce the risk of trading digital assets priced in non-linked virtual tokens or legal currencies is a problem to be solved.
A federation chain in a blockchain refers to a blockchain in which a plurality of organizations participate in management together, each organization operates one or more nodes, and data therein only allows different organizations in the system to perform read-write and send transactions and records transaction data together.

Specifically, a client that has completed authorization in a federation chain sends an owned digital asset to a digital asset database, the digital asset database returns a storage address identifier, such as a URI or a URL, of the digital asset to the client, the client generates a hash value of the digital asset according to the storage address identifier of the digital asset, and the client initiates a certification process, that is, the hash value and an owner address of the digital asset are sent to a federation chain system.
Step 402: the uplink participates in the consensus.
Specifically, after one node in the federation chain acquires the hash value and the owner address of the digital asset, the hash value and the owner address of the digital asset are identified in each node in the federation chain.
Step 403: and judging a consensus result.
Specifically, the alliance chain system determines a consensus result of each node, and if the consensus of each node is successful, the consensus result is successful, and then step 404 is executed; if the consensus of any one of the nodes fails, the consensus result is failure, and step 405 is executed.
Step 404: the non-homogenous passcertificate holding list in the owner account is updated.
Specifically, non-homogenization pass-certificates and corresponding homogenization pass-certificates of the digital assets are generated according to the hash value and the owner address of the digital assets, the non-homogenization pass-certificates are added to a non-homogenization pass-certificate holding list in an owner account, the homogenization pass-certificates are stored in the owner account, and the updating of the non-homogenization pass-certificate holding list in the owner account is completed.
Fig. 5 is a schematic view of an account of a digital asset owner provided in an embodiment of the present application, as shown in fig. 5, if a digital asset of the present deposit certificate is x3, and an owner of the digital asset is a, before the digital asset is deposited certificate, an account address of a is an account a, an account balance is 1024, an NFT holding list includes two digital assets x1 and x2, after the digital asset x3 is deposited certificate, the account address of the account a and the account balance are unchanged, but the NFT holding list includes three digital assets x1, x2, and x3, and the owner account further includes basic information of the digital asset x3, specifically, a current owner of the digital asset x3 is the account a, a corresponding number of the homogeneous certificates is 15, and the digital asset address of the digital asset is a URI.

If the originator of the sale request is not the current owner of the digital asset, the check fails and step 608 is performed.
If the initiator initiating the sale request is the current owner of the digital assets, the digital asset circulation system 602 based on the alliance chain acquires the account balance of the buyer 603, and determines the account balance of the buyer 603 and the homogenization certification amount.
If the account balance of the buyer 603 is less than the amount of the homogenization certification, the verification fails and step 608 is executed.
If the account balance of the buyer 603 is greater than or equal to the number of homogenization passes, step 609 is performed.
Step 608: and if the verification fails, ending the transaction.
Specifically, if the initiator initiating the sale request is not the current owner of the digital asset, or the account balance of the buyer 603 is less than the homogenization certification amount, the verification fails, and the transaction is ended.
Step 609: and if the verification is successful, updating the data.
The digital asset circulation system 602 based on the federation chain sends the storage address of the digital asset to the purchaser 603, further, the purchaser 603 acquires the digital asset according to the storage address, and the digital asset circulation system 602 based on the federation chain adds the non-homogenization pass certificate to a non-homogenization pass certificate holding list in the account of the purchaser 603, deducts the balance corresponding to the number of the homogenization pass certificates from the account balance of the purchaser 603, deletes the non-homogenization pass certificate from the non-homogenization pass certificate holding list in the account of the owner 601, and increases the account balance of the owner 601 by the balance corresponding to the number of the homogenization pass certificates, thereby realizing the change of the non-homogenization pass certificate ownership, and updating the balance of the account of the purchaser 603 and the account of the owner 601.
