Think it's covered in these comments and the blog post... but, think this is misunderstooding...

This is a single isolated experiment:
- NOT to fragment or hardfork
- TO VERIFY that the chain can be considered DECENTRALISED

The point is to remove the argument that "Deso is not decentralised".

If the nodes can be isolated and continue to mint, it proves that the chain is not reliant upon core nodes (i.e. Locked to centralised nodes as it has been previously... before POS)
