Answer

Sidechain anchoring is a blockchain technology that refers to the technology of creating a sidechain after the main chain and anchoring the sidechain to the main chain. The sidechain can verify the authenticity of transactions, blocks or other information occurring on the main chain.

In cross-chain authentication, the subscribing client is responsible for initiating cross-chain requests, receiving blockchain data from the publishing client, and verifying the authenticity of the data on the local blockchain.

The publishing client is responsible for publishing the data that needs to be cross-chain verified on the target blockchain and providing the data proof to the subscribing client.

The cross-chain interaction endpoint acts as a bridge to connect different blockchains, is responsible for receiving cross-chain requests from the subscribing client, forwarding the request to the publishing client, and finally returning the verification result to the subscribing client.

The cross-chain authentication system proposed in this patent does not require modification of the existing blockchain, but is connected through an independent cross-chain interaction endpoint, so it is called "non-intrusive".

"Proof" refers to information used to verify the authenticity of a transaction, such as a block header, Merkle tree path, etc. In this patent, the proof is used to verify whether the transaction on the target blockchain actually exists.

Simplified Payment Verification (SPV) is a lightweight blockchain verification method. The subscribing client only needs to download the block header and the Merkle tree path of the relevant transaction to verify the authenticity of the transaction.

The Merkle tree is a data structure that can compress a large number of data blocks into a unique hash value. During the SPV verification process, the subscribing client uses the Merkle tree path to quickly verify whether the transaction is included in the block.

The cross-chain authentication system proposed in this patent can be applied to cross-chain asset transfer, cross-chain identity authentication, cross-chain data exchange and other scenarios.

In addition to software implementation, the cross-chain authentication system proposed in this patent can also be implemented by hardware, firmware or a combination of hardware and software.
