Maersk, Moller Moller-Moller and IBM are using the blockchain-based digital tracking system to track cargo ships and containers. The three largest overseas shipping companies in the world are now using the same system. The system uses a shared governance system through which members hold others accountable for data added to the ledger. Members gain a comprehensive view of their data and can digitally collaborate as cargo moves around the world, helping create a transparent, secure, immutable record of transactions. More than 100 shipping and cargo firms have signed on.”]
