I don’t really see the problem here, even if your math is a off. (Statistics is difficult, I know). Connecting to many nodes to download faster is really not an issue and already happens. > Your proposal is also a lot less able to handle active adversaries: if > nodes are randomly dropping blocks, the probability that one block in > particular is dropped by everyone goes up significantly. You make the assumption that this new mode of pruning will be used by 100% of the network, this is not how distributed systems work. -- Tom Zander Blog: https://zander.github.io Vlog: https://vimeo.com/channels/tomscryptochannel _______________________________________________ bitcoin-dev mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
