Description

spec version 134

Note: Offset spec version by 1 due to initial testnet upgrade.

• Adds SenateMembers StorageMap, managed by sudo:
  • governanceModule.addSenateMember(senateMemberKey)
  • governanceModule.removeSenateMember(senateMemberKey)
• Updates Proposal voting logic:
  • Senate can instantly approve/reject Proposals with a 4/7 vote condition.
  • Proposals now no longer require 40 or 50 percent of all stake in the network to be approved. Instead, it tracks whether the total voter participant stake at the end of the Proposal expiry period is majority approval.
