Proof of Time : Byzantine resilient temporal ordering in Untrusted network

Shannon’s channel coding theorem (1948) assumes a passive channel operator with no economic interest in message ordering. Modern internet infrastructure violates this assumption structurally: NTP servers, BGP routing authorities, AI agent coordinators, and transaction sequencers are strategic agents whose utility is strictly monotone in the ordering they control. We formalize this as the Strategic Channel Controller Problem (SCCP)—a formal gap absent from classical information theory encompassing NTP manipulation, BGP hijacking, DNS poisoning, and autonomous agent ordering. We introduce Proof-of-Time (PoT), the first cryptographic primitive for SCCP, comprising multi-source temporal synthesis, a GRG integrity pipeline (Golomb-Rice→Reed-Solomon→Golay(23,12,7)) whose stage ordering is mathematically necessary (Theorems 1–3), and AdaptiveSwitch enforcement with equilibrium threshold V∗ derived in closed form (Theorem 4). We calibrate λ from 151,423 Timeboost express-lane auctions, yielding λ ∈ [$0.11, $1.13] ms−1 and V∗ ∈ [$8.67, $87.13], below which PoT eliminates ordering manipulation entirely. Deployment produces 70,000+ verified records; autonomous AI agents generate 55%—an unanticipated finding with structural implications for agent-to-agent economies.
