As shown in fig. 2, is a transaction implementation process in a transaction processing system.
Reference numeral 201 denotes two differently numbered assets #1001, #1002, each corresponding to the history 202 of the owner of a digital asset during circulation.
Each asset history 202 contains a record head, and transaction records segments. The recording head contains two parts, an initialization asset amount 203, and an owner address 204 of the current asset.
As shown in fig. 2, user a owns asset #1001, with an initial amount of 100. User B owns asset #1002, an initial amount of 10.
User a now needs to transfer asset amount 30 from #1001 to #1002 of user B. At this time, the user a is a paying party and the user B is a receiving party.
User a needs to create a transaction record segment that includes a type identifier 205, a new amount after the transaction is completed 206, a target address or target asset number 207, and a legal signature of the user 208 of the above information.
Specifically, user a creates a transaction record segment with type identifier = 0 (representing a payment transaction); new amount = 70 (indicating 30 deductions from the original 100 total); target address=0x237 … (address of token #1002 representing user B); signature of user a pair (0, 70,0x237 …) =0xa 16 ….

The transaction processor clears the expenditure C-Tree and the income C-Tree, waits for the transaction request in the next period and processes correspondingly.
The number of digital assets in the prior art is arbitrary, but the denomination is fixed. For example, 100 tens of thousands of digital assets with 5 denominations can be issued, and 50 tens of thousands of 10 denominations can be issued. Transfer requires 5/10 th of the transfer to the other party, and ownership of this digital asset, representing 5/10 th of the transfer, is changing. The amount that can be transferred is not arbitrary.
