Abstract

Disclosed are computer-implemented methods, non-transitory computer-readable media, and systems for managing transactions in multiple blockchain networks. One computer-implemented method includes identifying a first transaction in a first blockchain network that is a first Hash Time Locked Contract (HTLC) transaction in the first blockchain network, identifying a second transaction in a second blockchain network that is a second HTLC transaction in the second blockchain network different from the first blockchain network, determining that a first transaction commit time of the first HTLC transaction is earlier than a second transaction commit time of the second HTLC transaction and a first secret hash of the first HTLC transaction has a same value as a second secret hash of the second HTLC transaction, and in response, determining that the first HTLC transaction and the second HTLC transaction are associated with each other and related to a cross-chain transaction.
