A system for a shared and synchronous time series identification that matches a hardware clock-generating signal of a blockchain identified node device, with a generated data event time stamp and shared by all computing nodes participating in a complete system based on a blockchain design pattern and protocol. A blockchain cybersecurity system time signature is applied to synchronize the device level ID or device chain; this time sync is matched to the client master clocking time signal governing data transactions on the data event level or event chain. The combination of these two disparate blockchain mechanisms is termed as a multi-chain application. The matched time signals now provide referenced smart contract time sequencing. This matched time sequencing is unique and customized in its application to a multi-chain block chain cyber security application.
