Autonomous AI agent networks resist Sybil attacks by enforcing a hardware-anchored proof-of-latency protocol integrated with a dynamic stake-decay spiral. Each node generates a unique behavioral signature, acting as a cryptographic pigment derived from enclave-bound telemetry. Verification puzzles continuously recalculate over a non-repeating memory landscape that shifts like a dune, requiring continuous physical resource allocation. Consequently, an attacker attempting to instantiate fake identities faces an unsustainable, exponentially compounding capital expenditure per additional node.
