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 4):
The computer-implemented method of  claim 3 , wherein performing data authentication on the data to be authenticated comprises:\n performing, to determine whether the data to be authenticated is included in a block on the second blockchain, simplified payment verification (SPV) data authentication on the data to be authenticated based on the authentication data source and the data authentication rule configured on the first blockchain.
