According to Odaily, Anza has introduced two proposals aimed at implementing a penalty mechanism within the network, specifically targeting validators involved in creating 'duplicate blocks,' where the same block is generated twice. While the exact economic details of the penalty mechanism have not been finalized, the author of SIMD has suggested the destruction or functional abolition of the staked tokens of penalized validators.
Ashwin Sekar from Anza has proposed a parabolic penalty curve. Under this proposal, if 5% of a validator's staked tokens are found to be in violation, 1% of their staked tokens would be destroyed. In cases where 33% of the staked tokens are in violation, all staked tokens would be penalized. Sekar explained during a validator discussion that Ethereum's penalty curve is linear. He also noted that this penalty proposal is still in its early stages and such updates are not expected to be implemented until late summer 2025.
