- the basic chain can be used to establish a relationship between existing independent blockchains, so that the data interaction in the blockchain is no longer limited to a single blockchain, and the scope of value flow is no longer limited to A separate blockchain. That is, the basic chain can manage and supervise the operating parameters in the entire blockchain network.
- the basic chain transaction request may be a transaction request or other pending transaction request that occurs within a period of time in the basic chain network.
- Parachain is also a kind of blockchain, which is the opposite concept to the basic chain.

Data such as contracts or programmable currencies.
- a corresponding smart contract can also be written in the genesis block of the parallel chain, which is used for subsequent block generation nodes in the parallel chain to execute the smart contract.
- a smart contract in a parachain can provide that the parachain and the base chain jointly operate the chain account.
- a parachain smart contract stipulates that when a parachain network node finds that a set condition is met, it initiates a base chain transaction request to the base chain, requesting the base chain network node to process it.
- the basic chain transaction request may be a request for a basic chain network node to perform a transfer operation on a chain element of a chain account.
- the designated output account may be an account used to output a chain element in a chain account to other accounts.

- the deployment data such as the consensus mechanism, the incentive mechanism, the issued digital currency, and the template of the smart contract are written into the parallel chain.
- the genesis block of the parachain can control the later operation of the parachain. It can be seen that when creating a parachain, a parachain creation node can specify the incentive rules for the nodes participating in the establishment of the parachain in the underlying chain transaction request.
- S230 Execute the account smart contract to transfer the basic chain elements in the designated output account to the chain account.

- the chain elements can be transferred from the chain account to other accounts in the blockchain according to the rules stipulated in the account smart contract.
- a parachain creation node can transfer a certain amount of chain elements from the chain account according to the rules in the account smart contract to the account corresponding to the node participating in the parachain creation.
- a set number of chain elements in the chain account are evenly distributed to the accounts corresponding to the nodes participating in the creation of the parallel chain in an even distribution manner.
- the rules specified in the account smart contract may include at least one of the following:
- the set value chain elements are allocated according to the hash power contribution rules

- the set number may be a value set according to actual requirements, such as 10, 20, or 50, which is not limited in this embodiment.
- the computing power contribution rules can be artificially specified, and are used to measure the weight or ranking of the nodes that provide computing power. For example, in the first 5 block generation nodes, the weight of the hash power provided by each block generation node is 0.1, 0.2, 0.3, 0.2, and 0.2, or in the first 5 block generation nodes, each block generation The order of the computing power provided by the nodes from strong to weak is: block generation node 1, block generation node 3, block generation node 2, block generation node 5, and block generation node 4.

For example, if bitcoin is used as the basic chain element, and when the number of block generation nodes in the parallel chain network reaches 10, 100 bitcoins can be used to provide strong computing power based on 10 block generation nodes. Weakness is assigned.
- the 10 block generation nodes are assigned 5, 10, and 15, 10, 10, 20, 5, 10, 5, and 10 Bitcoins.
