IBM has filed a blockchain-based patent aimed at enhancing the security of blockchain networks to prevent a replay attack. The process entails the generation of a transaction with a signed security certificate and a unique once-only security value. This demonstrates that a network is allowed to conduct the transaction before it is transmitted. In this case, the protocol would be used by an organization called Blockstream in order to verify transactions on its network.

IBM and Alibaba are almost equal in terms of the number of blockchain-related patents filed up to August 2018.
