Blockchain Release

The core developers have tagged a new 2021.10.07.0 Hotspot firmware release which includes several updates. This is a mandatory update for manufacturers as it contains updates to PoCv11 code that will be required when we are ready to activate those chain variables and updates to how we will be doing block gossip in the near future. There are several updates in this release and more details are available in the blog but here are some highlights.

Improvements to Hotspot bandwidth utilization and Block Gossip

We have found that as the network expands, bandwidth expectations of individual Hotspots have gone up significantly and want to address this sooner than the Light Hotspot code is available. This release includes preparatory work to enable lower bandwidth gossip. Details are available in the PR listed below but at a high level, this change introduces a new protocol to gossip that dramatically reduces bandwidth utilization.

Critical Bug Fixes in PoCv11

This release also fixes critical bugs that would prevent activation of PoCv11. Once this blockchain release is on all Hotpots, Validators, ETLs, Routers and Node operators, we believe we can safely activate PoCv11. https://engineering.helium.com/2021/10/08/blockchain-release-block-gossip-state-channels-and-poc-v11-fixes.html
