Secured event monitoring leveraging blockchain

A computer system for secure event monitoring using blockchain, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• broadcasting, by a primary monitor and a backup monitor to a plurality of monitors, event data, wherein the plurality of monitors include the primary monitor, the backup monitor and at least one other monitor, wherein the plurality of monitors are configured to identify consensus in a network of monitors, wherein each monitor in the plurality of monitors has a temporary log, wherein each monitor in the plurality of monitors shares a permanent log, wherein the plurality of monitors can write to the shared permanent log once a consensus is reached and a predetermined number of events have been logged;
• receiving and logging, by each monitor in the plurality of monitors in the temporary log of each monitor in the plurality of monitors, the primary monitor broadcasts of event data;
• receiving and marking, by each monitor in the plurality of monitors in the temporary log of each monitor in the plurality of monitors, the backup monitor broadcasts of event data;
• and marking, by the primary monitor, event data entries of data as confirmed entries, unconfirmed entries or conflicting entries in the temporary log of the primary monitor, wherein the primary monitor is a coordinator monitor, and wherein the coordinator monitor moves linearly to a next monitor in the plurality of monitors once a predetermined number of events have been logged and hashed.
