but it's still an interesting metric that you can roughly infer network security from (eg 51% attack difficulty)

- viraptor 13y agoWouldn't that depend on the cumulative hashing rate rather than number of nodes? I.e. I don't think it matters if 1k new nodes join if they're not doing any hashing.
- bdcs 13y agoYou are correct that a 51% attack depends on hashing. Other attacks, Sybil, etc. depend on gaining network access to the (a) real bitcoin node with the latest blocks -- more nodes, I guess, helps prevent people from being unable to find the true network. Hence jgarzik's push to put bitcoin nodes into space to beam the latest blocks to earth, à la GPS.
