In case of a hard fork voting, the decred code does not allow the existence of 2 blockchains. The "defeated" blockchain "dies".
Hard fork happens automatically and takes everyone in the same direction.
It is impossible for a group to continue on the old blockchain and keep it alive.
It's impossible to happen at Decred what happened to ETH and BTC.
The devs took great care in developing this.
It is one of the main differentials of decred.
This is misleading, imo. If there's a contentious hardfork, the losing party can modify the codebase to allow their chain to continue. They're going to hardfork anyway. There's no magic protection against people making a one off or permanent change to the rules of the system to allow their form to live.
That's my point. There's nothing that can stop a determined minority from splitting away from the main chain. But with Decred, it might be the true community majority made up of small HODLERS who delegate their votes to pools.
