According to PANews, PolkaWorld has announced the commencement of Coretime trading on Kusama, marking the end of the parallel chain era. This development follows the approval and implementation of Kusama's 373rd public proposal, which upgraded the Kusama relay chain runtime to v1.2.0 and introduced the Coretime feature. Subsequently, the community approved Kusama's 375th public proposal last Friday, allowing the Coretime chain to begin Coretime sales. Currently, Kusama is in the Renew Period, which involves the sale of bulk cores.

Following the Renew Period, the Sale period begins, which is a demand-based purchasing period. This includes price discovery (Dutch auction, price decreases over time) and fixed price stages. Agile Coretime introduces a more flexible and dynamic way of managing blockchain resources. With the launch of Agile Coretime sales, the resource allocation pattern on Kusama has changed. Parallel chain auctions have stopped, and existing parallel chains and future parallel chains will:

Existing parallel chain leases will automatically migrate to bulk coretime. Unstarted leases will be cancelled, and locked KSM will be refunded.

Existing parallel chains can use the coretime renewal feature to continue allocating bulk coretime to their cores without going through the regular purchase process.
