#523·Encointer Runtime Upgrade v8

After Launching its first community in May 2022, The Encointer team was able to gather a lot of experience how the protocol can be improved for better growth possibilities and user experience. Moreover, a minor attack vector has been discovered and one critical bug needs fixing through runtime upgrade that has only been fixed through a workaround currently.

Please find the release notes along with the srtool build here: https://github.com/encointer/encointer-parachain/releases/tag/1.2.0

Update Process

As a common-good parachain, Encointer runtime can only be upgraded through Kusama governance. It is important that the runtime upgrade happens during the registering phase of Encointer's ceremony lifecycle. We will therefore submit a preimage later this week and propose a referendum to be timed with support of the Kusama's technical committee such that the enactment happens during the desired range of days.

• Best option: Enactment between Aug 4th and 9th
• Fallback: Enactment between 14th and 19th
