We propose increasing `slashing.signed_blocks_window` from 100 to 5000.
Currently `slashing.signed_blocks_window` is 100 and `slashing.min_signed_per_window` is 50%.
Therefore validators must sign at least 50 blocks out of the last 100 blocks to prevent being slashed because of downtime.
With the current block time of 5.76 seconds, validators cannot be offline for more than 4m48s.
If this proposal will pass:
Validators will be able to sign at least 2500 blocks out of the last 5000 blocks to prevent being slashed because of downtime.
Validators will be able to be offline for 4 hours at a time without being slashed, which will give more time for maintenance and chain updates.
