The 12-Line Anti-Bot Trick That Saved Our Airdrop Snapshot From Sybil Farms
A new anti-bot technique successfully identified 94% of Sybil wallets during a testnet airdrop. The method utilized behavioral entropy analysis on RPC call patterns, proving more effective than traditional filters. This approach flagged 23,400 Sybil clusters while maintaining a low false positive rate of 6.3%.
- ▪The anti-bot trick involved a 12-line Python heuristic that analyzed wallet interactions.
- ▪The method processed 847,000 wallet interactions in just 4.2 hours.
- ▪It ran within an Intel TDX enclave, ensuring RPC logs remained unencrypted.
