Abstract

A system for recording and playback of electronic event sequence utilizing a distributed ledger may be configured for: monitoring a source system; recording data regarding the source system onto a distributed ledger, the data including event data regarding electronic events occurring within the source system; constructing, from the event data of the distributed ledger, a testing dataset including event data regarding simulated electronic events; and simulating, in a testing environment, the simulated electronic events using the testing dataset. The system may be further configured for selectively cloning a section of the distributed ledger, wherein the section includes event data regarding a subset of the electronic events occurring within the source system; and reconstructing the section of the distributed ledger in the testing environment.
