Sybil Attack
When one person creates tons of fake accounts to trick a network or voting system into thinking they're many different people.
Blockchains fight Sybil attacks with staking requirements, proof-of-personhood, or reputation systems. It's a constant battle in decentralized projects.It's like one kid putting on a bunch of different costumes and trying to vote multiple times in a class election.
Real world: Someone creates hundreds of fake wallets to farm airdrops or manipulate governance votes on a DAO.
💡 If an airdrop or reward seems too easy to farm with multiple wallets, it's probably designed to catch Sybil attackers — don't risk it.
