The world's three largest overseas shipping companies are now using the same blockchain-based digital tracking system: TradeLens. Developed by Maersk and IBM, TradeLens is a platform based on the Hyperledger blockchain that allows competing shipping companies to share information while tracking cargo ships and containers in near real time. As the #1 patent holder in the Cryptocurrency sector, IBM owns numerous patent documents directed to blockchain technology, their applications ranging from managing energy purchase agreements to tracking various assets. The company's vast IP portfolio reflects the strength of its platform TradeLens, and why it was adopted by not only the three largest shipping companies, but also more than 100 other shipping and cargo firms.
