Adversarial Clock Problem

Time

The adversarial clock problem describes the challenge of establishing a reliable, unmanipulable time source within a decentralized network, where participants may have incentives to distort time for financial gain. In options trading and derivatives, accurate timekeeping is critical for determining expiration, settlement, and other time-dependent contract conditions. The integrity of a decentralized financial system relies heavily on preventing adversaries from manipulating timestamps to execute trades or liquidations at favorable, yet illegitimate, moments.
