It should allow miners sealing new blocks every 13~15 seconds on average for another ten months and allow both Ethereum 1.x and Ethereum 2.0 developers to conclude the merge. + +## Specification +#### Relax Difficulty with Fake Block Number +For the purposes of `calc_difficulty`, simply replace the use of `block.number`, as used in the exponential ice age component, with the formula: + + fake_block_number = max(0, block.number - 11_000_000) if block.number >= FORK_BLOCK_NUMBER else block.number + +## Rationale +This will delay the ice age by another ~26 million seconds (approximately ~9.89 months), so the chain would be back at ~30 second block times in summer 2022. Hopefully, by then the Eth1-to-Eth2 merge will be concluded and the ice age fulfilled its task. + +## Backwards Compatibility +This EIP is not forward compatible and introduces backwards incompatibilities in the difficulty calculation. Therefore, it should be included in a scheduled hardfork at a certain block number. It's suggested to consider this EIP either with or shortly after the Berlin hard-fork but not later than July 2021. + +Alternatively, in order to maintain stability of the system, a it can be considered to activate this EIP along with EIP-1559 fee market changes in a bundle. With the delay of the ice age, there is a desire to no further increase inflation and rather incentivize users to participate in proof-of-stake consensus instead. + +## Security Considerations +There are no known security issues with this proposal. + +## Copyright +Copyright and related rights waived via [CC0](https://creativecommons.org/publicdomain/zero/1.0/).
