Abstract:
One or more implementations of the present specification provide cross-blockchain authentication. A subscribing client corresponding to a first blockchain and using a cross-chain client of a cross-blockchain interaction system, retrieves data from a second blockchain, where the data is published by a publishing client for use as an authentication data source, where the cross-blockchain interaction system comprises the subscribing client, the publishing client, and the cross-chain client, where the publishing client corresponds to the second blockchain, where the cross-chain client is separately interconnected with the subscribing client, and where the publishing client and the first blockchain are used as a sidechain that is anchored to the second blockchain, which is used as a main chain. Data to be authenticated is received from the second blockchain. The data to be authenticated is authenticated based on the authentication data source and a data authentication rule configured on the first blockchain.

Claim (Index 2):
The computer-implemented method of  claim 1 , wherein retrieving the data comprises:\n initiating, by the subscribing client and as a subscription, a subscription request to a cross-chain interaction end, wherein the subscription request is used to notify the cross-chain interaction end of a subscription condition; requesting, using the cross-chain interaction end and based on the subscription condition, data on the second blockchain that satisfies the subscription condition from the publishing client; and retrieving, by the subscription and for use as the authentication data source, the data on the second blockchain that is published by the publishing client and that satisfies the subscription condition.
