Motion #15 (#14): Runtime upgrade to fix issue 527 (fixed point precision) and prep for issue 500 (locked stake) fix

[hangyin]

This Motion brings an external proposal to Democracy. The council and the technical committee will jointly put a on-chain runtime upgrade v1080.

The new runtime version 1080 mainly addresses the fixed point precision problem that preventing the reconciliation of issue 500. Once the upgrade is done, I will make another motion to trigger the issue 500 fix on the blockchain.

Bug Fixes and Improvements

• Cap the removing stake by user locked amount

Oops, Motion 14 was not successfully executed because I’ve incorrectly execute ParachainSystem.authorizeUpdate() by a Motion directly. I intended to create a Democracy proposal and propose a Motion to speed up it.

Therefore I’m preparing Motion 15 again with the correct configuration:

1. democracy.note_preimate: Subscan | Substrate based blockchain explorer
   • encoded_proposal: 15032b020a8495507d85ac06b1b37d2d3c149ebe6ae5c544f92780f10b58eaee3afc

2. Create Motion 15 with the call democracy.external_propose_majority
