You have it backwards.
Nodes decide if they will append your block to their chain.
A miner that decides to mine out of consensus blocks is just burning money, and will be on their own fork with their “100% votes” that nobody else uses.
Give it a try, spend a few million on mining equipment and then try forcing something on the network.
It’s not a democratic system, never was.
- lottin 5y agoNodes have zero decision power, as far as I understand. They just go with the chain that is the most expensive to produce.
- inter_netuser 5y agoThat’s incorrect. The proposed block must comply with the rules your node enforced, or it will not be accepted. It’s not just work, but also the entire consensus-set they must abide by. Miners cannot force new rules, if there is no consensus.
- lottin 5y agoNo, you're misunderstanding everything. The consensus mechanism is about agreeing about the contents of the blockchain, not about the rules that make up the bitcoin protocol.
- drdeca 5y agoEh? Can't miners refuse to include transactions that don't adhere to new conditions in addition to old ones? If 51% of miners decide to, after block #N, not include any transaction that doesn't satisfy the predicate P in any block they produce, nor mine on any chain which has a block after block #N which has a transaction that doesn't satisfy predicate P, then the longest chain will have all the transactions after block #N be ones which satisfy P, and furthermore, if the other 49% of miners are aware that this is happening, if they want their blocks to be in the longest chain, they have incentive to follow the same rules when mining. This is the logic behind soft forks, is it not?
