Gavin Wood: PoS is dragging down the Polkadot security model and requires fundamental replacement and reconstruction

According to PolkaWorld, at yesterday's Web3 Summit event, Polkadot founder Gavin Wood pointed out that Polkadot's Proof of Stake (NPOS) is dragging down its security model and requires fundamental replacement and refactoring. Polkadot pays up to $500 million in security costs annually, mainly from Staking rewards. In the current structure, this fee is 85% of Polkadot's annual inflation, and this 85% fee is monetized by validators and nominators, flowing out of the ecosystem and not converted into network use or ecological activity. Gavin believes that this is an "unsustainable" fiscal structure that will undermine the discipline of online finance, weaken the accuracy and efficiency of ecological incentives. He proposes an alternative path called PoP (Proof of Personality), which uses "who are you" as the basis for power and trust on the chain. Gavin proposed a solution: to reduce security expenses by 80% in the short term, such as setting fixed salaries for validators, limiting self staking and ultra-high return expectations, introducing a "stable issuance model" for DOT, raising the threshold for validators, and introducing mechanisms such as KYC and interviews; Introduce PoP and Individuality in the mid-term, and activate an identity driven security model; Mid term supplementary tools include closing invalid resources and introducing native stablecoins.
