Problems solved by technology

[0004] However, limited by the rules of chain currency issuance in the blockchain, the chain currencies in each blockchain cannot communicate with each other, thus weakening the interactive function between blockchains
If the restrictions imposed by the rules of the blockchain itself on the chain currency are completely broken, the chain currency may not be recognized by the blockchain nodes, and the credibility and value will be lost.

Embodiment 1

[0044] Figure 1A It is a flowchart of a blockchain-based currency exchange method in Embodiment 1 of the present invention. The embodiment of the present invention can be applied to the situation of currency exchange for chain currencies issued by different parallel chains in the super chain network. The method is executed by a chain currency exchange device, which is implemented by software and / or hardware, and is specifically configured in an electronic device carrying a block chain node.

[0045] Such as Figure 1A The blockchain-based currency exchange method shown includes:

[0046] S110. Obtain a currency exchange request.

[0047] Exemplarily, acquiring a currency exchange request may be: acquiring a currency exchange request input by a user through a human-computer interaction interface, wherein the currency exchange request includes the source currency and the target currency, the account to which the source currency belongs, and the source At least one of the curr...

Embodiment 2

[0064] figure 2 It is a flowchart of a blockchain-based currency exchange method in Embodiment 2 of the present invention. The embodiments of the present invention perform additional optimization on the technical solutions of the foregoing embodiments.

[0065] Further, before the operation "determine the target exchange amount based on the amount to be exchanged", add "determine the exchange rate based on the target currency amount in the target chain account and the total source currency available in the source parachain", In order to improve the mechanism for determining the exchange rate.

[0066] Such as figure 2 The blockchain-based currency exchange method shown includes:

[0067] S210. Obtain a currency exchange request.

[0068] S220. Determine the exchange rate according to the target currency amount in the target chain account and the total source currency available in the source parachain.

[0069] Among them, the total amount of available source currency is...

Embodiment 3

[0079] image 3 It is a flowchart of a blockchain-based currency exchange method in Embodiment 3 of the present invention. The embodiments of the present invention perform subdivision optimization on the basis of the technical solutions of the foregoing embodiments.

[0080] Further, the operation "according to the amount to be exchanged and the target exchange amount, transfer the source currency from the user account to which the source currency belongs to the source chain account of the source parachain, and transfer the target currency from the target parachain The target chain account is transferred to the user account", which is refined as "according to one of the amount to be exchanged and the target exchange amount, initiate a source currency transfer transaction request on the source parachain to transfer the source currency Transfer from the user account to which the source currency belongs to the source chain account of the source parachain; after confirming the op...

Abstract

The embodiment of the invention discloses a block chain-based chain currency exchange method, device and equipment and a medium. The method comprises the steps of obtaining a currency exchange request; determining a target exchange amount according to the exchange exchange exchange rate between the source currency and the target currency in the currency exchange request and the amount to be exchanged; and according to the to-be-exchanged amount and the target exchanged amount, transferring the source currency from the user account to which the source currency belongs to the source chain account of the source parallel chain, and transferring the target currency from the target chain account of the target parallel chain to the user account. According to the scheme, the source chain account of the source parallel chain and the target chain account of the target parallel chain are introduced; and the source chain account and the target chain account are used as intermediate hubs for exchanging the chain currencies issued by different parallel chains, so that cross-chain exchange of the chain currencies is realized, the limitation of the block chain rule on the chain currencies is broken through, and meanwhile, the credibility and the value of the chain currencies are ensured.

Description

technical field [0001] Embodiments of the present invention relate to block chain data processing technology, and in particular to a block chain-based chain currency exchange method, device, equipment and medium. Background technique [0002] In the existing blockchain technology, in order to support the execution of transactions in the blockchain, and to encourage the blockchain generation nodes, that is, miners, to pay for the workload of generating blocks, the blockchain usually issues chain currency, using Chain currency for transactions and payment of miners' fees. Chain currency is a virtual currency issued by the blockchain and guaranteed uniqueness. It is generated, recorded and transferred in the form of strings. Its authenticity is guaranteed by the operating rules of the blockchain and is guaranteed by each node in the blockchain network. recognized. A typical on-chain currency at present is Bitcoin. With the establishment of other alliance chains and private c...
