IBM, a technology giant, has a set of gold flow services in the supply chain. The original process was mostly manual and interlocking, from order establishment, order amount input, packaging, and delivery. Until the invoice is sent, as long as any link goes wrong, you must wait. According to IBM statistics, an average of 2.2 million disputed orders take an average of 44 days to process each, and these kidnapped accounts cost up to $1 billion. Therefore, IBM has built a supplier platform to use smart contracts to master the golden flow operation of every job. When a smart contract receives two shipping notices from the manufacturer and the transportation industry at the same time, the terms of the contract will be automatically fulfilled and allocated to both parties according to the order. IBM only entrusted the verification errands to the blockchain, reducing the dispute resolution time from 44 days to 10 days, and the early release of $1 billion of money.
