Custom software that redefines when a block is valid is _an attack on bitcoin_
People don’t decide what a valid block is — consensus rules do.
If half of the full-nodes and miners are rejecting these valid blocks and the other half aren't, there will be two conflicting chains if the two chains are growing at the same pace. 🤦♂️ This is effectively a 51% attack/fork on the longest bitcoin chain.
Refute the central point instead of dancing around it like an ETH maxi, or I’m just going to ignore & deem you as a bad actor. Thought you were better than this!
