Abstract:
Implementations of the present specification provide for cross-blockchain authentication. A public key of a database engine comprising a trusted node of a second blockchain is determined by a subscribing client included in a system for cross-chain interaction. The public key is used as an authentication data source. The system comprises the subscribing client (corresponding to a first blockchain), a publishing client (corresponding to the second blockchain), and a cross-chain interaction end separately connected to the subscribing client and publishing client. Data that is to be authenticated in the second blockchain is determined using the cross-chain interaction end. The data is published by the publishing client. The data to be authenticated is signed by the database engine using a private key of the database engine. The data authentication performed on the data uses the authentication data source and a signature of the data to be authenticated.

Claim (Index 8):
A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:\n determining, by a subscribing client included in a system for cross-chain interaction, a public key of a database engine comprising a trusted node of a second blockchain, wherein the public key is used as an authentication data source, wherein the system comprises the subscribing client, a publishing client, and a cross-chain interaction end, wherein the subscribing client corresponds to a first blockchain, wherein the publishing client corresponds to the second blockchain, and wherein the cross-chain interaction end is separately connected to the subscribing client and the publishing client; determining, by using the cross-chain interaction end, data that is to be authenticated in the second blockchain and is published by the publishing client, wherein the data to be authenticated is signed by the database engine based on a private key held by the database engine; and performing, based on the authentication data source and a signature of the data to be authenticated, data authentication on the data to be authenticated.
