Anza proposed two proposals to implement a punishment mechanism (slashing) in the network, mainly targeting validators for so-called "duplicate blocks", which refers to the situation where the same block is created twice. Anza has not yet decided on the specific economic details of the punishment mechanism, but the author of SIMD suggested destroying (or functionally abolishing) the punished stake tokens. Anza's Ashwin Sekar also proposed a parabolic punishment curve: if 5% of the validator's stake tokens are violated, 1% of their stake tokens will be destroyed; and if 33% of the stake tokens are violated, all stake tokens will be punished. Sekar explained at a validator discussion that Ethereum's punishment curve is linear. Sekar also said that the punishment proposal is still in the early stages, and such updates will not be launched until at least the end of summer 2025.
