And not even over the sidechain actually. I have yet to have had someone sucesfully describe how miners can control the sidechain. They just repeat the meme.

Nodes matter for different reasons, miners matter for different reasons. Bip300 is a soft fork, meaning backwards compatibility. It does not affect anyone not interested in sidechains. Miners often need to coordinate through softforks to respond to attacks or improvements that would take too long to get community consensus. They do not break bitcoin. They do not add more coins, they do not change difficulty adjustment, and other thinga that make bitcoin, bitcoin. Nodes matter for network affect, verification, ect.

Another thing, since it is miners not nodes confirming withdraws or merge mining a sidechain, this is also why bip300 could be activated without user consensus. If a majority of miners activate it, and users hardfork, they would temporarily be less secure than the miner backed chain. This balance of power is by design. Drivechain is just one person in a mexican standoff on hot day sipping some water and offering it to everyone else holding a gun at eachothers head.

I do not recall miners coordinating through softforks to respond to attacks. Do you have an example?

Nope that was mistaken. I think i had ordinals in mind when i said that, which obviously doesn't fit. The improvement part still applies :

Bitcoin Stack Exchange

How do we know which soft-forks were implemented using User-Activated Soft Fork or Miner-Activated Soft Fork?

This seems to be the most common definition

When a majority of miners upgrade to enforce new rules, it is called a miner-activated soft fo...

You wasted typing time on this reply instead of showing how. Drivechain utxo's are just like any other users utxo. What are nodes going to be blocking exactly ?
