Embodiment 1

[0059] refer to figure 1 and figure 2 , figure 1 It is a schematic diagram of the principle of the blockchain information cross-chain interaction method in Embodiment 1 of the present invention, figure 2 It is a schematic flow chart of the blockchain information cross-chain interaction method in Embodiment 1 of the present invention, including the following steps:

[0060] S1. The t1 node of the blockchain T judges whether the blockchain A meets the first feedback condition, and if so, the t1 node of the blockchain T obtains and verifies the first data information of the blockchain A;

[0061] If the verification is passed, the block producing node of the blockchain T receives the t1 node verification signal and stores the first data information on the local chain to generate a block; the t2 node of the blockchain T receives the block and sends it to the blockchain B send transaction;

[0062] If the verification fails, the block producing node receives a signal that the...

Embodiment 2

[0107] participate Figure 4 , Figure 4 It is a schematic flow diagram of the blockchain information cross-chain interaction method applied to the t1 node in Embodiment 2 of the present invention, a blockchain information cross-chain interaction method applied to the t1 node of the blockchain T, and the t1 node is Any node in the blockchain T (can be configured in advance), including the following steps:

[0108] S200, the t1 node judges whether the blockchain A meets the first feedback condition, and if so, the t1 node of the blockchain T obtains and verifies the first data information of the blockchain A;

[0109] In step S200, the first feedback condition is preset on the blockchain T.

[0110] In step S200, also include:

[0111] S2001. After the blockchain A meets the first feedback condition, the t1 node of the blockchain T reads the first data information of an arbitrary node a1 on the blockchain A, and sends the first data information of the node a1 Converted into...

Embodiment 3

[0126] participate Figure 5 , Figure 5 It is a schematic flow diagram of the blockchain information cross-chain interaction method applied to the block generation node in Embodiment 3 of the present invention, a blockchain information cross-chain interaction method applied to the block generation node of the blockchain T, including the following steps :

[0127] S300. If the block producing node receives the t1 node verification pass signal, store the first data information on the local chain to generate a block;

[0128] If the block producing node receives the signal that the t1 node has not passed the verification, it discards the first data information;

[0129] Among them, the block producing node stores the first data information on the local chain, that is, the block producing node of the blockchain T packs the block chain A information and generates a block, and the t2 node converts the block produced by the block producing node and Send to blockchain B; and send ...

Abstract

The invention provides a blockchain information cross-blockchain interaction method and system applied to a t2 node, and a device. The method comprises the steps that the t2 node of a blockchain T receives a block and sends a transaction to a blockchain B; the node t2 of the blockchain T starts a monitoring operation to read the block information of the blockchain B, determines whether the blockchain B successfully gives a block; if so, the node t2 reads the data of the blockchain B, and verifies whether the read data of the blockchain B meets a threshold condition, or if not, determines that cross-blockchain information copying fails; if it is verified that the read data of the blockchain B meets the threshold condition, the cross-blockchain copy value condition is determined, the cross-blockchain copy information is successful, and the t2 node sends a packaging instruction to a block output node; and if the threshold condition is not met, cross-blockchain information copying fails. According to the method, the information on the blockchain A is stored on the blockchain B through the additional blockchain T, so that information copying of an isomorphic blockchain can be supported, and cross-blockchain information copying of a heterogeneous blockchain can also be supported.

Description

technical field [0001] The present invention relates to the field of block chain technology and the field of data processing technology, and in particular to a method, system, and device for cross-chain interaction of block chain information applied to t2 nodes. Background technique [0002] With the continuous advancement and development of science and technology, the blockchain has swept the world with an unstoppable trend. The benefits of the blockchain are extended to various fields, and the benefits of the blockchain are brought into full play as much as possible. Compared with the traditional development path, the technical development path of the blockchain is faster, more convenient, safe and reliable. The development of this technology has won the development of various fields and the recognition and use of more and more people. [0003] With the rapid development of blockchain, it also faces many problems. The interoperability between blockchains greatly limits th...
