Thus, the innovation revolves around gathering customer data analytics, such as spending trends, which Amex will use to offer incentivized rewards. According to the patent, certain account holders would be eligible for "value added offers" which may involve "virtual currency."

As for the use of a blockchain system, the document implies that the databases that would be utilized to deliver this system might be blockchain-backed.

The blockchain structure may include a distributed database that maintains a growing list of data records. The blockchain may provide enhanced security because each block may hold individual transactions and the results of any blockchain executables. Each block may contain a timestamp and a link to a previous block. Blocks may be linked because each block may include the hash of the prior block in the blockchain. The linked blocks form a chain, with only one successor block allowed to link to one other predecessor block.

This move by Amex might be yet another strong signal that major corporations are actively seeking to integrate the technology into their infrastructures for providing goods and services.

Cobalt & Lithium Supplies to be Tracked With DLT

The platform will be created by the Everledger together with Circulor using Hyperledger Fabric

Everledger, a British startup, has partnered with Circulor to develop a platform based on the Hyperledger Fabric blockchain to track supply chains of cobalt and lithium.

Everledger specializes in using blockchain to combat counterfeiting of precious stones, in particular diamonds. The company’s management said it intends to expand its business using blockchain to control the supply of rare minerals used in the production of batteries.

Well-known carmaker Mercedes Benz is already using Circulor technology to track its supply of cobalt and its carbon footprint. Circulor and Everledger share a similar concept - with the help of the blockchain they control the observance of social and environmental standards in mining. Therefore, startups decided to develop a joint product.

Everledger co-founder Leanne Kemp and Circulor CEO Doug Johnson-Poensgen said their solution will work on the Hyperledger Fabric blockchain. The possibility of interacting with IBM is also being discussed.

Poensgen added that the platform will be used not only to track cobalt production in the Democratic Republic of Congo, but in different regions of the world. For example, lithium mining in the Atacama desert leads to water pollution, so the solution on the blockchain is aimed at preventing environmental disasters.
