Is there network split risk for Taproot activation with two releases (Bitcoin Core and Bitcoin Taproot)? In this article from Aaron van Wirdum he states there is a risk of a network split with two releases (Bitcoin Core and Bitcoin Taproot) not following exactly the same activation mechanism(s)? Is this true?
This question was asked by Andrew Asmakov and has been paraphrased.
No. With a softfork, a network split is only possible if miners create invalid blocks. This is something they can do with or without a softfork, so it is not an issue specific to softforks.
It is important for the economy to use their own full nodes to avoid the risk of being led off by a miner attack in the form of invalid blocks. This remains true with softforks, where upgrading is necessary to retain full node security.
