Embodiment 1
[0064]In this embodiment, the ECDSA algorithm is used as the digital signature algorithm, the elliptic curve is secp256k1, the SHA-256 algorithm is used as the secure hash function, the wallet address generation algorithm of Ethereum is used to generate the user's wallet address, and the HMAC in NIST SP800-90 is used -DRBG algorithm as a pseudo-random number generation algorithm.
[0065] Set up asset issuer CB and asset underwriter CMB 1 ,...,CMB nb and blockchain user DU 1 ,…, DU nu , set nb=7, nu=10000, and with the operation of the system, the values of nb and nu can change dynamically, the public-private key pairs of all entities are generated by the ECDSA key generation algorithm, and the asset underwriter CMB 1 ,...,CMB nb Have public and private key pairs (bpk 1 , bsk 1 ),…,(bpk nb , bsk nb ), DU 1 ,…, DU nu Belonging to the same asset underwriter CMB s , and have public and private key pairs (upk 1 , usk 1 ),…,(upk nu , usk nu ).

Embodiment 2
[0111] Embodiment 2 is similar to the rest of Embodiment 1, except that the blockchain system uses different pseudo-random number generation algorithms, hash algorithms, and digital signature algorithms such as Hash_DRBG, SHA-3, DSA, SM4, and SM2.

Abstract
The invention relates to the technical field of blockchain finance, in particular to an efficient digital asset transaction method based on an account model. Aiming at an existing AFCoin technology framework, a blockchain forest and endorsement node selection method is introduced, a receipt processing process is integrated, complete implementation steps of the framework are given, and the framework is applied to the field of digital asset transaction, so an efficient digital asset transaction method based on an account model is obtained. Under a semantic framework of AFCoin, the blockchain forest is a plurality of blockchain structures maintained by a central bank, and different commercial banks have different blockchains, but are published by the central bank in a unified manner; the endorsement node selection method ensures that a commercial bank cannot select a specific commercial bank responsible for endorsement, and prevents cheating between commercial banks. When a central bank is used as an issuer of digital assets, a commercial bank is used as a seller of the digital assets, and a user is used as a holder of the digital assets, an efficient digital asset transaction methodcan be obtained.
Description
technical field [0001] The present invention relates to the field of blockchain financial technology, and more specifically, to an efficient digital asset transaction method based on an account model. Background technique [0002] The Internet digital economy is booming, and new digital assets can be seen everywhere. In addition, the transaction efficiency of new digital assets is usually low. For example, the peak value of Bitcoin transactions is no more than 7 transactions per second, and the peak value of Ethereum mainnet transactions is about 15 transactions per second. In fact, this cannot meet the needs of a large number of concurrent transactions in practical applications. [0003] In recent years, my country's central bank and asset issuers in many European and American countries have actively carried out research on the digital legal currency system, and piloted the promotion and application of digital legal currency. In 2016, the Bank of England took the lead in r...
