This version cancels the recent BKS grant by rejecting the current block 1183900, so it basically makes the node forget all the blocks made during the last week. It will fork the network between 5.x and 6.0 nodes. All nodes will stay connected to each other but on different chains, until the 6.0 chain eventually becomes the best chain for all nodes (it will take some time even if all the shareholders switch now).
If the grant is actually wanted by the majority shareholders they must just keep running version 5.x. This version exists to allow them to revert it if they want to. If there’s no consensus the two chains will coexist.
The 6.0 chain starts when the grant had 43% of the votes. Shareholders must upgrade quickly and mint if they don’t want the grant to still pass on the new chain. And they must make sure they mint continuously in the future to prevent this kind of problem.
After the upgrade shareholders who minted during last week must run this RPC command to clear all their orphaned transactions, otherwise most of their shares won’t be available to mint:
The command can take several minutes to process.
