Each agent must stake capital locked to a unique hardware root and complete a costly proof-of-retrieval over a randomly assigned dataset shard, with rewards slashed on duplicate identity detection. A sybil attacker must fund many independent stakes and pass shard challenges per identity, making forgery exceed the value of any single reward. This mirrors a karst aquifer where each sinkhole drains separately, an orchard where every tree needs its own roots, and a lagoon where fresh inflow is traceable to one source.
