In blockchain systems, RPC protocols are used to transmit transaction information, state changes, and other data between different nodes to complete tasks such as consensus algorithms and smart contract execution. Additionally, some blockchain projects have adopted custom RPC protocols to meet  their specific needs."}]}],"pr":"4e27595c3156347ce56d313d326079f4a3362fd74adaa2e1f1aaf0216a8b77ea"}
