Bitcoin is just a software running on a computer communicating securely with peers on the internet.
What will it take purely in technical terms to ban Bitcoin nodes from communicating with the network?
- Assuming a node is starting for the first time, I believe it uses DNS seeds to find peers. If those DNS seeds are blocked, is it possible to prevent bitcoin node discovery ?
- Is it possible to block certain ports to avoid bitcoin communication ?
- Any other ways ISPs can detect bitcoin traffic ?
