CROSS-CHAIN TRADING METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2019/042101

Kind Code:

A1

Abstract:

A cross-chain trading method and apparatus. In the method, for any node over a first blockchain in blockchains to which a plurality of connected transactions belongs, after receiving connected transactions sent by a consensus node, the node needs to determine, according to identifiers of anchoring transactions comprised in the connected transactions, whether the anchoring transactions are valid transactions; if the anchoring transactions are valid transactions, transactions which belong to the first blockchain are written in the first blockchain according to the identifiers of the blockchains to which the plurality of transactions belongs, so that the plurality of connected transactions over the plurality of blockchains can be ensured to be submitted successfully and synchronously, thereby effectively avoiding the problem in the prior art that transactions that are submitted successfully may not be able to be canceled when multiple transactions fail to be submitted synchronously. Moreover, because multiple transactions possess atomicity, there is no need to relate to an intermediate state and pull back transactions according to specific service types.
