Abstract: Distributed systems and methods for encrypting data on a blockchain network are disclosed. One system comprises at least one injector coupled to a node on the blockchain, a controller coupled to the injector, and a generator coupled to the controller. The injector intercepts messages bound for the blockchain and encrypts data in the messages using encryption information received from the controller. The controller acquires encryption information from the generator, which generates encryption keys and derives encryption information from those encryption keys. The encryption information may be divided into multiple parts and distributed between a plurality of injectors. As a result, to assemble an encryption key for encrypting or decrypting data, an injector may have to cooperate with other injectors to acquire sufficient encryption information to re-assemble the encryption key.
