IBM wants to secure blockchain-based contracts

IBM has applied for a patent for a method that ensures that a network of connected devices can securely execute blockchain-based “smart” contracts.

According to a report in Coindesk, the tech giant has said in its patent documents filed that “one example method of operation may include determining a proof-of-work via a device and using a predefined set of nonce values when determining the proof-of-work, storing the proof-of-work on a blockchain, and broadcasting the proof-of-work as a broadcast message.”
