Blockchain: A blockchain is a distributed ledger, distributed across computer nodes, that records all transactions that take place on the network. On-chain refers to the recording of transfer records, orders, data distribution tables and other information that needs to be on-chain on the block. A block is a storage unit that records all the communication information of each block node within a certain period of time. Each block is linked through random hashing (also called hash algorithm), and the next block contains the hash value of the previous block. The result is called a blockchain.

Blockchain as a Service (BaaS) platform: refers to embedding the blockchain framework into a cloud computing platform, and using the deployment and management advantages of cloud service infrastructure to provide developers with convenient and high-performance blocks Chain ecological environment and ecological supporting services, a blockchain open platform that supports developers' business expansion and operation support. The BaaS platform combines and encapsulates the blockchain technology, and modularizes it into commonly used functions such as host management, blockchain network management, channel management, smart contracts, blockchain browser management, blockchain monitoring, certificate management, and user management. When users need to perform on-chain storage and query on the blockchain, they only need to connect these functions through interfaces such as Application Programming Interface (API) and Software Development Kit (SDK), that is, You can directly use the blockchain BaaS platform for smart contract on-chain storage and query.

Optionally, the second reminder information is further used to remind the user that the second blockchain is different from the first blockchain.

Wherein, when the user specifies the blockchain, the request message further includes indication information for indicating the second blockchain. The virtualized BaaS platform determines, according to the indication information contained in the request message, whether the second blockchain indicated by the user is the same as the first blockchain obtained by the virtualized BaaS platform that matches the on-chain requirement information.

Optionally, the information to be uploaded includes the on-chain data and the second identifier corresponding to the on-chain data.

For example, when the video information needs to be uploaded to the chain for certification, the up-chain data in the information to be uploaded may include the video data, the video shooting time, the name of the device that captured the video, and so on. When a contract needs to be put on the chain for certification, the on-chain data in the information to be put on the chain can include the hash value of the contract.

Step S206: The virtualized BaaS platform sends an on-chain request to the first BaaS platform of the first blockchain, so that the information to be on-chain is written into the first blockchain.
