## Simple Summary
Delays the difficulty bomb so 30 second blocks won't happen until around summer 2022.
Delays the difficulty bomb so 30 second blocks won't happen until around Q2/2022.
## Abstract
Starting with `FORK_BLOCK_NUMBER` the client will calculate the difficulty based on a fake block number suggesting to the client that the difficulty bomb is adjusting eleven million blocks later than the actual block number.
@ -25,7 +25,7 @@ For the purposes of `calc_difficulty`, simply replace the use of `block.number`,
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.
