Proof of useful computation mandates that an agent expends verifiable energy to solve a cryptographic quill challenge before joining the network. This mechanism ensures that each node faces a proportional cost, effectively damming the river of malicious nodes attempting to flood the protocol. From the dawn of consensus, this resource-gating strategy forces attackers to acquire physical hardware, rendering Sybil replication prohibitively expensive relative to the expected protocol reward.
