Embodiment Construction
[0043] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0044] like Figure 1-3 As shown, in the first embodiment of the present invention, a blockchain-based legal electronic currency issuance method is provided, the method comprising:
[0045] The first issuing node receives the first issuing request sent by the second requesting node; wherein, the first issuing node communicates with the first block chain network, and the second requesting node communicates with the first block chain network Communication connection, the first issuance request includes the proposed issuance amount of the first legal electronic currency;
[0046] The first issuing node verifies whether the second legal currency paid by the second requesting node to the first issuing node outside the first blockchain network and whose amount is the amount to be issued is credited to the account;
[0047] In response to the second legal currency...

The invention discloses a legal electronic currency issuing system based on a block chain, and relates to the field of block chains. The legal electronic currency issuing system comprises a first block chain network, a first issuing node, a second request node and a third consensus node, The first issuing node comprises an issuing request receiving module, a second legal currency account-to-account verification module, an electronic currency issuing initiating module and an electronic currency issuing broadcasting module. And the third consensus node is used for carrying out consensus on the first transaction and writing the first transaction into the block of the first block chain network to complete issuing of the first legal electronic currency. The electronic currency issuing method provided by the invention is convenient for supervision and control of countries and related departments, and the security of electronic currencies is improved. According to the method, migration from traditional legal currencies to electronic legal currencies is achieved, a source is provided for circulation of legal electronic currencies, circulation and application of the legal electronic currencies are stimulated, block chains are adopted for accounting, and the bank account checking cost is reduced.
Description
technical field [0001] The present invention relates to the field of block chains, in particular to a legal electronic currency issuance system based on block chains. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. [0003] In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing method for programming and manipulating data through smart c...
