Answer

The operating environment and requirements of the blockchain are dynamically changing. In order to adapt to these changes, such as the expansion of network scale and increase in transaction volume, the consensus mechanism needs to be changed dynamically to ensure the performance and security of the blockchain.

The indicators proposed by patent US11082291B2 to trigger the change of consensus mechanism include: number of nodes, network resource utilization, cryptocurrency balance, CPU utilization, memory utilization and network bandwidth utilization, etc.

First, establish a network of validators who can vote on existing and new consensus mechanisms. Then, collect and record the votes of each validator, and determine whether to switch to a new consensus mechanism based on the voting results.

"Trust module" refers to the part of the blockchain system responsible for security and operation, such as consensus mechanism, encryption algorithm, etc. In the dynamic change of blockchain trust configuration, the trust module is responsible for executing the new consensus mechanism and ensuring the security and consistency of blockchain data.

The performance of the consensus mechanism can be evaluated by evaluating indicators such as transaction throughput, transaction confirmation time, resource consumption, etc.

The "feedback registry" is a record maintained by each validator to record the voting behavior of other validators during the consensus process. If a validator's vote is often inconsistent with the majority of validators, it will be recorded in the "Feedback Registry" and may be punished, such as reducing its voting weight or being removed from the network.

"Service Level Agreement" (SLA) defines the performance and reliability standards that a blockchain system should provide. In the consensus mechanism, SLA can be used to define thresholds for indicators such as transaction confirmation time and transaction throughput. When these indicators exceed the threshold, changes in the consensus mechanism can be triggered.

"Temporary consensus procedure" refers to a consensus mechanism temporarily used in a specific transaction. For example, when the source or content of a transaction is at risk, a more secure consensus mechanism can be used to process the transaction.

The technical solution proposed in this patent mainly solves the problem of dynamically changing the consensus mechanism according to actual needs without interrupting the operation of the blockchain, thereby improving the flexibility and adaptability of the blockchain.

Taking supply chain finance as an example, as the number of participants increases and the scale of transactions expands, the consensus mechanism initially adopted may not meet the needs. By dynamically changing the consensus mechanism, transaction processing speed can be increased, costs can be reduced, and security can be enhanced, thereby better supporting the development of supply chain finance.
