IBM to use Bitcoin blockchain technology to help companies monitor supply chains

IBM recently announced the launch of a platform for corporate users to test "blockchain" record-keeping technology in their supply chains.

The technology hopes to expand the use of blockchain technology, which already underlies bitcoin and is used by banks and exchanges to track financial transactions, beyond the financial services industry. While companies such as Nasdaq, Depository Trust & Clearing, JPMorgan Chase and Bank of America are experimenting with blockchain technology, only a few companies, including Toyota, are using it to monitor their supply chains.

Blockchain is a data structure that can be used to create and share a digital ledger of transactions. It uses cryptography so that anyone with permission can add information to the ledger in a secure manner without the use of a centralized system. Once a block of data is recorded in the blockchain ledger, it is difficult to change or delete.

Proponents say these features make blockchains well suited for recording and monitoring large amounts of data, such as short-term loans or the millions of parts in an airline supply chain.

IBM's new service allows supply chain clients to build and test blockchains using the company's LinuxOne operating system in a secure cloud. The service is aimed at companies that want to track high-value goods through complex supply chains.

IBM’s initial clients include Everledger, which helps companies trace the origins of diamonds, allowing buyers to identify which diamonds come from regions where forced labor is rife or where proceeds from previous sales have supported violence.

Everledger is developing a system to record the entire journey of diamonds from mines to jewelry stores, and has been using various blockchain tools, including Bitcoin's general ledger. Everledger CEO Leanne Kemp said Everledger is testing IBM's technology and is expected to launch it globally by the end of this year.

Kemp said that many diamond transactions today are recorded on paper, which is easy to modify or forge. "This 150-year-old industry relies on credit transactions."

Bill Fearnley, research director at market research firm IDC, said blockchain technology is well suited to tracking diamonds and other commodities that require information about their origins and previous owners because it creates a permanent record that cannot be altered.

“Any high-value asset can be better tracked and historical information cannot be tampered with,” he said.

IBM hopes to establish its position in the blockchain industry by developing code and building laboratories to make it easier for users to try blockchain software.

Jerry Cuomo, vice president of IBM Blockchain, said supply chain is second only to the financial industry as the most likely application area for this technology.

Suppliers are also likely to feel pressure from blockchain systems, Fearnley said.
