Description
Technical Field
The invention relates to the technical field of block chains, in particular to a token accounting method, a token accounting system and a storage medium based on a UTXO model.
Background
In the UTXO model: TX is an abbreviation for Transaction, and TXO is TX output: contains a value and a script that specifies who has access to the transaction (e.g., requires a private key signature). UTXO is the un post TXO (Unspent transaction output) and only the signature for "as-used" transactions can be a valid signature. Each transaction has a number of transaction inputs, i.e., sources of funds, and a number of transaction outputs, i.e., destinations of funds. Generally, each transaction costs (pend) an input to produce an output, and the output produced is the "unspent transaction output," i.e., the UTXO.
Token refers to a value-encrypted digital voucher that can be circulated.
In the block chain network, different nodes carry out consensus on services in the block chain through a specific consensus algorithm, and various data information is transmitted and stored on the chain, so that different service requirements are realized under the condition of decentralization. The blockchain network needs to be maintained, for a public chain, the role of maintaining the blockchain network is called miners, the behavior of maintaining the blockchain is called contribution of the miners to the blockchain, and the contribution of the miners to the blockchain is recorded in the public chain by using token of the UTXO model.
For a alliance chain, the alliance chain is built by each enterprise based on a business scene, and all the enterprises maintain normal operation of the alliance chain, so for the alliance chain, the contribution value of each node cannot be measured through maintenance contribution, but the contribution value of each node should be measured based on business contribution.
