Abstract

A blockchain asset that is transferred from a second blockchain member is received at a first blockchain member in response to an asset transfer request for transferring an asset between a payer and a payee, where the first blockchain member and the second blockchain member associated with a blockchain. In response to receiving the blockchain asset, an off-chain asset transfer-out operation for the payee is performed by the first blockchain member. If the off-chain asset transfer-out operation fails, a transaction reversal application for an asset transfer transaction corresponding to the asset transfer request is written into the blockchain by the first blockchain member. In response to writing the transaction reversal application, an asset clearing with the second blockchain member for an off-chain asset corresponding to the off-chain asset transfer-out operation is performed by the first blockchain member.
