Embodiment Construction

[0056] Embodiments of this specification will be described below with reference to the accompanying drawings.

[0057] figure 1 A schematic diagram showing a cross-chain system according to an embodiment of this specification. like figure 1 As shown, the cross-chain system includes a first blockchain 11 , a relay terminal 12 and a second blockchain 13 . For example, the first block chain 11 includes account A, and the second block chain 13 includes, for example, account B, both of which are user accounts. When account A in the first blockchain wants to transfer money across the chain to account B in the second blockchain, it can do so by means of an authenticated message (AM message). Specifically, by initiating the first transaction for cross-chain transfer, account A reduces its balance by the number of transfers, and deposits the first data (data 1 in the figure) into the first blockchain, wherein the number is The number of exchangeable resources (eg tokens) in the fir...

Abstract

The embodiment of the invention provides a cross-chain resource sending method and device. The cross-chain sending is sent from a first account of a first block chain to other block chains. The firstblock chain is connected with a relay end. The relay end is also connected with at least one other block chain, wherein a second block chain is included. The method is executed by the first block chain. The method comprises: a first account initiating a first transaction used for sending resources across chains, so that based on execution of the first transaction, reducing the first resource balance of the first account by a first number, storing consensus first data in a first block chain, and the first data comprising an authenticable message; and providing the first data and the first position information to the relay end so as to send the authenticable message to the second block chain, so that a second number of second resource balances of a second account in the second block chain isincreased.

Description

technical field [0001] The embodiment of this description relates to the field of blockchain technology, and more specifically, to a method and device for sending resources across chains. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is a decentralized distributed database technology, which is characterized by decentralization, openness and transparency, non-tamperable and trustworthy. Every piece of data in the blockchain will be broadcast to the blockchain nodes of the entire network, and each full node has a full amount of consistent data. With the popularity of blockchain technology, many different types of chains have emerged, which are applied in fields such as finance, health care, supply chain, asset management and traceability. However, most on-chain applications (cryptocurrency or smart contracts) cannot cross the boundaries of the current chain, and cannot cooperate with other chains to realize the circulation o...
