According to Foresight News, voting has started on a proposal to increase Polkadot's ideal staking rate to cope with the approximately 100 million DOTs that will be unlocked on the 23rd of this month. The tokens unlocked this time come from the DOTs locked by the first batch of users participating in crowd lending. Increasing the ideal staking rate aims to increase DOT staking rewards to encourage unlocked DOTs to participate in staking.
