BLOCKCHAIN-BASED MESSAGE SERVICES FOR TIME-SENSITIVE EVENTS

摘要

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing blockchain-based message services. One of the methods includes: receiving shipping data and shipping insurance order data associated with a purchase order; determining whether a shipping insurance order corresponding to the shipping insurance order data is valid; initiating a consensus algorithm to record the shipping data and the shipping insurance order data on a blockchain; generating a first event message including a notification that a shipping insurance of the purchase order is effective; receiving shipping insurance premium distribution data indicating a distribution of shipping insurance premium associated with the shipping insurance order to one or more service providers; determining that the distribution of the shipping insurance premium is legal; initiating the consensus algorithm of the blockchain network to record the shipping insurance premium distribution data on a blockchain; and generating a second event message notifying that the shipping insurance premium is distributed according to the shipping insurance premium distribution data.
