Answer

The "final state" of a blockchain refers to the summary of the latest status of all assets in the blockchain. It is closely related to the practicality of a blockchain because the final state can be used as a starting point for generating a new blockchain, thereby reducing the size of the existing blockchain and improving its performance.

"Parent blockchain" refers to the original blockchain, while "child blockchain" is a new blockchain generated from a portion of transactions selected from the parent blockchain. A child blockchain can adopt different rules, policies, and structures than the parent blockchain.

"Selecting transactions" refers to selecting a portion of transactions from the parent blockchain to build a new child blockchain. The criteria for selecting transactions can be set according to actual needs.

"Migration blocks" are new blocks that contain transactions that migrate from the parent blockchain to the child blockchain. It contains information about the migration transactions, a machine-readable link to the relevant previous block in the parent blockchain, and information about the final state.

The purpose of the "anti-block" is to explain the reason why the final state migrated from the parent blockchain to the child blockchain. It contains an explanation of the migration transaction and links to the relevant previous block in the parent blockchain.

The purpose of "re-migrating" new transactions to the child blockchain is to ensure that all subsequent transactions are added to the child blockchain instead of the parent blockchain.

Splitting a blockchain into multiple child blockchains can improve the management efficiency and performance of the blockchain. Each child blockchain can focus on a specific type of transaction or asset and can adopt different rules and policies.

In some cases, it is necessary to include "history blocks" in the new blockchain to provide some contextual information to the new blockchain before it starts processing all new transactions.

To ensure that the connection between the parent blockchain and the new blockchain is accurate, the state of the new blockchain needs to contain a link to the archived historical blockchain. For example, a reference to the final block of the parent blockchain can be included in the seed block of the new blockchain.

The main advantages of the system and method described in this patent application are the ability to reduce the size of the blockchain without sacrificing the cryptographic security of any blockchain, and to improve the uptime, practicality, and performance of large blockchains.
