Coin age mechanism implementation method for UTXO architecture

Abstract

The invention discloses a coin age mechanism implementation method for UTXO architecture, and the method comprises the steps of building a conventional block at any node, and building a coin age transaction at a first transaction position of a transaction list of a block body; counting the coin age value of the coin age transaction through a public-level coin age statistical function, and verifying the legality of the coin age transaction used by the block through input, output and signature algorithms; if the coin age transaction is legal and other detection items of the block are legal, taking the block as a legal block; if the coin age transaction is illegal, taking the block as an illegal block, and discarding the illegal block; and if the block is legal, confirming the block to be linked, confirming the coin age transaction in the block at the same time, and returning the use time of the coin age in the coin age transaction automatically to zero. According to the invention, lightweight coin age statistics can be realized, offline legal verification is supported, creator confirmation is not needed, the method can be conveniently used as consensus parameter input in a consensusalgorithm, and the mobility of coins is improved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for implementing a currency age mechanism for UTXO architecture. Background technique [0002] Coin age, that is, the age of the coin. It is an input parameter that can improve the probability of consensus block generation during the consensus process. [0003] In the traditional use of currency age, currency age is generally only applicable to the POS (Proof of stake) consensus mechanism. The unit of currency age is days, and it must be supported by a complete account balance system to be effective. [0004] The traditional currency age mechanism is difficult to build and use directly based on UTXO (Unspent Output Transacition, unspent transaction output), while the traditional currency age based on POS often leads to some problems that are difficult to solve in consensus. Including: (1) Account system that is difficult to maintain: the traditional use of currenc...

Problems solved by technology

[0004] The traditional currency age mechanism is difficult to build and use directly based on UTXO (Unspent Output Transacition, unspent transaction output), while the traditional currency age based on POS often leads to some problems that are difficult to solve in consensus. Including: (1) Account system that is difficult to maintain: the traditional use of currency age depends on the account balance system and requires pledge tokens. First, it will cause difficulties in initial capital circulation and distribution, and second, it will cause miners to continuously hoard tokens. Conduci
