v1.1.3

Spec Version

Spec Version: 153

Description

This release fixes a bug that occurs when registrations are turn off . Currently the epoch does not run. This PR fixes it by running the epoch , but setting the subnet's emissions to 0

PR: #602

v1.2.1-pre-release

Spec Version

Spec Version : 187

Highlights

Consensus Based Bonds(Liquid Alpha):

• PR: #552

This change introduces bond calculations based on the consensus values of neurons/ uids. It makes weight setting by validators more speculative.

Safe Mode:

• PR #553

This allows the chain to be put into Safe mode

Prevent Accidental changes to storage structs:

• PR : #533

Increase reliability our of development flow by making it harder to make trivial changes to struct (e.g the order of mappings), which can have severe consequences upstream.

Fix - adjust senate call

• PR : #537

Fixes an bug in the Senate/ Root module preventing new users from joining the senate.

Full Changelog: v1.1.2...v1.2.1-pre-release

v1.1.2

v1.1.2

Spec Version: 152

Description

This is release fixes a bug that occurred when setting root weights .

The function now checks the hotkey as opposed to the coldkey to assert they have enough stake to set weights.

v1.1.1

Spec Version

Spec Version : 151

Highlights

Commit Reveal

• PR: #396
• In order to mitigate the effects of weight copying , we have implemented a commit reveal scheme. Validators are now able to conceal their weights by submitting hashing to the chain , and then later revealing them. This reduces the chances of weight copiers performing better than honest validaor

No emissions for subnets with registrations turned off

• PR: #474
• From this release onwards , subnets will only earn emissions if they have their registration turned on.
