This invention relates to the field of distributed storage technology and provides a data collaboration method and system for distributed transaction terminals. The method involves each transaction terminal performing erasure coding on its local ledger data to generate a set of data fragments consisting of original data fragments and verification data fragments. These data fragments are then distributed and stored across different transaction terminals according to distributed storage rules, and the terminals exchange online status and fragment integrity information. When a request to access the target ledger is received, the terminal storing its fragments is located based on the ledger identifier, and the fragments are retrieved in parallel to reconstruct the target ledger. When a terminal is detected to be offline or a fragment is corrupted, online terminals collaborate to reconstruct the original data using surviving fragments, re-encode new fragments, and distribute them to healthy terminals. This invention, through erasure coding and distributed collaborative storage, reduces storage overhead while improving system fault tolerance and data availability, achieving efficient and reliable distributed ledger data collaborative management.

An interceptor on the sending side intercepts an outgoing service request and attaches a unique identifier header that must be presented with the request and with any retries of the request. An interceptor on the receiving side sees the unique identifier and queries a private data store to see if the request has been processed previously. If the request has not been seen before on the receiving side, the application processes the request as usual, and the receiving side interceptor captures the return payload along with the unique identifier. If the request has been seen before, then the receiving side interceptor simply returns the captured payload from the successful processing by the application.
