Original Proposal Text

Replaces the unreviewed Cosmos SDK default liveness parameters (100-block window, 50% minimum signed, 1% downtime slash) with the Cosmos Hub values (10000-block window, 5% minimum signed, 0.01% downtime slash). At 6s blocks, a validator is jailed after about 15.8 hours of downtime instead of about 5 minutes. Double-sign slash (5%) and jail duration (600s) do not change. Parameters: signed_blocks_window: 10000 min_signed_per_window: 0.050000000000000000 downtime_jail_duration: 600s slash_fraction_double_sign: 0.050000000000000000 slash_fraction_downtime: 0.000100000000000000 More details: https://gist.githubusercontent.com/sovr-team/5a8769f4a840cfbdcdedde5ec5b5e8f1/raw/2f7d55179d7d257ce0741e3e4c46bffb01020a5d/slashing-liveness.sovr-1.metadata.md
