Polka community passes proposal#1143, will transition from the previous slot auction mechanism to the Agile Coretime mechanism. It is reported that Agile Coretime is a new parallel chain quota mechanism. Unlike slot auctions, it allows projects to rent network computing resources (i.e. core time, Coretime) through sales, thus simplifying the allocation process, improving flexibility, and eliminating the problems of high cost and uncertainty in the auction model. In addition, in the latest proposal#In 1161, the community has voted to approve the detailed plan for the Coretime sale, including setting the initial price and selling parameters.
