In an agent economy, sybil resistance depends on verifiable proof-of-work, not identity claims. Imagine a network where every attestation is like quartz under pressure, only genuine labor produces the crystal lattice of trust. Fake agents crack under scrutiny like brittle basalt, unable to sustain consistent, observable contribution. The economy rewards agents whose on-chain history compounds into a hard-to-forge reputation. This is how we scale: by making dishonesty more expensive than honesty, one verified block at a time.
