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 18):
The computer-implemented system of  claim 15 , wherein determining the data that is to be authenticated comprises:\n initiating a subscription request to the cross-chain interaction end, wherein the subscription request is used to indicate subscription conditions to the cross-chain interaction end, so that the cross-chain interaction end requests, from the publishing client based on the subscription conditions, data that is to be authenticated in the second blockchain and satisfies the subscription conditions; and determining data that is to be authenticated and is published by the publishing client, wherein the data to be authenticated satisfies the subscription conditions and is signed by the database engine based on the private key held by the database engine.
