Protocol Physics Security

Protocol physics security refers to the inherent robustness of the blockchain's consensus rules and cryptographic foundations against adversarial behavior. It focuses on how the underlying code prevents exploits like double spending, unauthorized state changes, or chain manipulation.

By modeling the network as a system of interacting agents and rules, researchers can identify vulnerabilities in the incentive structure or the consensus logic. This field examines how changes in the protocol, such as a hard fork, affect the overall stability and security of the financial assets involved.

It combines game theory with computer science to ensure that the system remains trustless and resistant to failure. Maintaining protocol physics security is the primary defense against systemic risks.
