This threshold is typically defined as more than half (or a specific ratio) of the nodes agreeing to modify the information. In practical operations, the method of calculating the security threshold may vary depending on the blockchain protocol. However, generally speaking, the calculation of the security threshold is closely related to factors such as the number of nodes, node distribution, and the punishment mechanism for tampering with information. To ensure the security and stability of the blockchain network, developers will weigh various factors when designing the blockchain protocol to determine an appropriate security threshold. This threshold can protect the security of the blockchain network while allowing for timely adjustments to be made."}]}],"pr":"2ad4e9368e93012eed069f3cd8c939672062b06b3e161a34956e80f6ca19f217"}
