Exemplarily, suppose there are UTXO accounts and Account accounts created in the consensus node. If the user selects the UTXO account as the account for storing the acquired digital assets, the consensus node will store the acquired digital assets in the UTXO or Account. In the UTXO account; if the user selects an Account account as the account for storing the acquired digital assets, the consensus node stores the acquired digital assets in the Account account as UTXO or Account.

In an optional embodiment, the method further includes:

In this alternative embodiment, a data block is divided into two parts, namely "block header" and "block body". The block header is used to record some descriptive information, and the block body is used to record " Transaction" list. The block header includes six fields, which are the version number, the hash value of the previous block, the Merkel root, the preset difficulty value, the timestamp, and the random number to be found. The mining process is to perform a series of conversions, connections and hash operations on the above six fields, and successfully find a random number that meets the conditions: the value after the hash operation is higher than the hash value of the preset difficulty value Small, then mining is successful. The consensus node performs mining on the blockchain network, and after successfully digging a newly generated data block in the blockchain network, the data block is stored. The blockchain system will issue a certain amount of tokens as mining rewards to consensus nodes that have successfully mined. In addition to obtaining mining rewards, consensus nodes can also obtain transaction fees corresponding to all transaction information in the data block.

The data block generated after the previous synchronization or subscribing to the data block is determined as the newly generated data block, and the blockchain digital wallet can periodically synchronize or subscribe to the newly generated data block on the block chain and execute it. Display the face value of the UTXO account or the amount of the Account account to the user, the purpose is to facilitate the user to manage assets, know how many assets there are, and what transactions can be made.

In an optional embodiment, the method further includes:

In this optional embodiment, the preset threshold is a preset threshold used to evaluate whether the data block is consensus completed. In different blockchain systems, the number of consensus nodes required to complete the consensus of the data block is different, that is, the preset threshold is set according to the blockchain system. For example, in the Bitcoin system, if the number of consensus nodes participating in the consensus reaches 51% of the entire consensus node, the consensus on the data block can be considered complete; otherwise, when the number of consensus nodes participating in the consensus is less than that of the entire consensus node At 51%, it is considered that the consensus on the data block has failed. For another example, in the DigiFinex Token (DFT) system, the number of consensus nodes participating in the consensus reaches 2/3 of the entire consensus node before the consensus on the data block can be considered complete; otherwise, the consensus node participating in the consensus When the number is less than 2/3 of the entire consensus node, it is considered that the consensus on the data block has failed. The consensus node broadcasts the data block to other consensus nodes on the blockchain network, and performs a consensus on the data block through other consensus nodes to verify whether the data block is valid. When the data block consensus is completed, indicating that the data block is valid, the consensus node stores the data block. When the consensus of the data block fails, it indicates that the data block is invalid, and the consensus node does not store the data block.

In other embodiments, during the process of storing the data block or after storing the data block, the consensus node can also detect whether the transaction data in the data block fails to be written into the storage space. If the transaction data is written If the storage space fails, you can rewrite it.

It should be understood that when a user needs a transaction, one or two or more of the above accounts can be selected as the transfer-out account, and the assets in the transfer-out account can be signed transactions. The transfer-in account can be a transfer Account address or UTXO address of the incoming party.

It should be noted that because Ethereum's Account can support a Turing-complete virtual machine and a Turing-complete smart contract running on it, the contract address of this blockchain system uses the Account address. For account transactions, the smart contract is executed directly; for UTXO account transactions, or UTXO account hybrid account account transactions, when calling the contract, the UTXO account transaction needs to be converted into the input message of the smart contract before executing the smart contract. When the smart contract is executed, the service fee consumed can be refunded to the Account or UTXO account in the form of Account or UTXO.

The blockchain asset processing method based on the multi-asset model described in this embodiment can integrate the advantages of each asset model by generating account addresses for accounts of different asset models, allowing users to mix their own multiple assets to achieve Asset privacy transactions and other functions, the multi-asset model makes the system more scalable and brings users a better transaction experience.
