What is Sybil Attack?

A sybil attack is named after a case study of split identities. In crypto it means a single actor spins up dozens or thousands of wallets to look like a crowd, so they can farm more airdrop tokens or swing a governance vote in their favour.

This matters for honest reward seekers because projects fight back with sybil detection. If your wallet pattern looks like a farm, freshly funded from one source, repeating identical actions, you can be filtered out even if you meant well. Genuine, varied, human-looking usage tends to survive these filters.

Example: someone funds 500 wallets from the same exchange withdrawal, runs the same three transactions on each, then expects 500 airdrop allocations. Analysts cluster those wallets together and disqualify the batch.

Safety note: do not buy “pre-farmed” wallet bundles or join schemes promising guaranteed airdrops through mass accounts, as many are outright scams that harvest your funds. Focus on using products you actually find useful. Related concepts include eligibility criteria, snapshot, and airdrop.
