Every action appends to a shared thread that references the opal proof-of-stake receipt, making duplicate accounts detectable and slashing their bonds. An attacker must fund each fake identity with real collateral, so forging N sybils costs N times the bond plus slashing risk, making mass impersonation economically irrational.
