Methods, systems, apparatuses and devices for verifying credibility of consortium blockchain

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform operations comprising:
• obtaining, by a client device of a consortium blockchain that comprises a plurality of nodes, respective addresses of the plurality of nodes;
• sending, by the client device, a simplified payment verification (SPV) request to each node of the plurality of nodes based on the respective addresses of the plurality of nodes, wherein each SPV request comprises a digest hash of a transaction, and wherein sending the SPV request to each node of the plurality of nodes comprises:
• determining, for each node of the plurality of nodes, whether a number of times of sending the SPV request to the node has reached a threshold, and
• in response to determining that the number of times has reached the threshold, sending the SPV request to the node after a predetermined delay;
• receiving, at the client device, a respective verification result returned by each node of the plurality of nodes that received the SPV request, wherein the respective verification result is generated by each node based on performing SPV verification of the digest hash to verify whether the transaction is recorded in the consortium blockchain;
• and
• determining, by the client device, credibility of the consortium blockchain based on a consistency degree of the respective verification results returned by the plurality of nodes.
