I've always wondered why blockchains always assume all nodes are equal in trust. Why I can't add special trust to certain nodes? I mean this is what makes a 50% attack possible. Most people can trust their family members, close friends and neighbors, while only anonymous nodes can lead to a 50% attack.
- WillDaSilva 6y agoAllowing users to assign different levels of trust to different nodes complicates things. If nothing else it requires that the user be able to accurately identify which node is which. This typically requires exchanging keys through a secure external service. I agree it's a worthwhile goal, but more work needs to be done to figure out how to avoid the problems found in systems like the PGP web of trust.
