Anza proposes to implement a penalty mechanism in Solana, and some of the tokens pledged by penalized validators will be destroyed

Anza has put forward two proposals to implement a slashing mechanism in the network, mainly to punish validators for so-called "duplicate blocks", that is, when the same block is created twice. Anza has not yet decided on the specific economic details of the punishment mechanism, but the authors of SIMD propose to destroy (or functionally abolish) the staked tokens that are punished. Anza's Ashwin Sekar also proposes a parabolic penalty curve: if 5% of the validators' staked tokens violate the rules, 1% of their staked tokens will be destroyed; if 33% of the staked tokens violate the rules, all staked tokens will be punished. Sekar explained in a validator session that Ethereum's penalty curve is linear. Sekar also said that the penalty proposal is still in its early stages and that such an update would not be available until late summer 2025 at the earliest.
