According to a report by PANews, Polkadot founder Gavin Wood stated at the Web3 Summit event that Polkadot's NPoS is undermining its security model, with annual security costs reaching up to $500 million, accounting for 85% of inflation. Gavin believes this is an unsustainable financial structure and suggests an 80% reduction in security expenses in the short term, such as setting fixed salaries for validators, limiting self-staking and extremely high return expectations, and introducing mechanisms like KYC. In the medium term, he proposes introducing PoP and Individuality, starting an identity-driven security model, and supplementing tools to shut down ineffective resources and introduce native stablecoins. #HumaFinance
