Hello, I just wanted to comment that I have a question about BTC updates, those of the software itself, like segregated witness or Taproot. How do they schedule an update on all nodes and who are the "leaders" so to speak? Is it the miners themselves, together with whales and nodes, who decide that the nodes put: in block 12000392 a new type of transaction called "taproot" will be added or how are these decisions made? what is the process? as programs on a blockchain that is already working?
There's an earlier post, here on SN, that addresses this fairly comprehensively:

Oh man, this is a big discussion. I recommend reading this blog to understand bitcoin's security better: https://www.coindesk.com/markets/2016/11/13/bitcoins-security-model-a-deep-dive/
