On October 25th, PolkaWorld announced on the X platform that the ideal staking rate for DOT has increased from 51% to 59%. It is expected that the staking reward for DOT will decrease by about 7% (from 1 DOT to 0.93 DOT). In addition, PolkaWorld stated that this is to leave enough space for the unlocked DOT for leasing 6-13 crowd loans, ensuring that the reward will not decrease significantly. If the DOT for crowd loans is staked at the previous ideal rate of 51%, the reward will decrease significantly. Setting the ideal rate to 59% provides a buffer for these additional DOT, avoiding a sharp decrease in rewards before the staking rate exceeds 59%.

It is reported that after the block height reaches 17856000 (on October 24th), the first batch of 113 million DOTs participating in crowd loans in the Polkadot ecosystem will be unlocked, accounting for about 7.4% of the total issuance.
