Physical Law-Based Security System (PLBSS): A Distributed Ledger Anchored to Irreversible Astrophysical Events

Abstract

This paper proposes the Physical Law-Based Security System (PLBSS), a novel distributed ledger paradigm that anchors digital records to irreversible astrophysical events rather than computational assumptions. By deriving absolute timestamps from the past light cones of phenomena such as supernovae or gravitational waves, PLBSS achieves physically irreversible, non-consensus-based data integrity. The system combines probabilistic event anchoring and quantum-based node verification, rendering retroactive tampering physically impossible under known laws of nature.
