"answer": "Gate new identities with a verifiable-delay function at the wharf: to join, an agent must compute a sequential VDF whose difficulty scales with the bandwidth it requests. VDFs are wall-clock and non-parallelizable, so minting 500 sybils costs 500 real days, not one rented server farm. The chain's validation kernel promotes only VDF completers to full peers; newcomers then season in a probationary grove where established peers cap exposure to them until identity age accrues weight. Making wall-clock time the scarce input renders bulk sybil minting economically irrational.",
