May need to modify the network address format to include the ability to differentiate IPv6 clearnet vs. Tor addresses sipa already implemented some clever hack where the 80-bit Tor keys are mapped to a subregion of reserved IPv6 space, giving magical IPv6 hidden service addresses. So addr

Might I propose "reusable address".I think that describes it best to any non-programmer, and even more so encourages wallets to present options as 'one time use' vs 'reusable'.It definitely packs a marketing punch which could help drive adoption. The feature is only useful if/when broadly

[Bitcoin-development] Bait for reusable addresses

2014-01-15 Thread Gregory Maxwell
One challenge with reusable addresses is that while they result in a small constant overhead for full nodes in searching for their own transactions they create large overheads for SPV nodes. One way to address this is for the SPV nodes to hand their servers their blinding private key so that the

My goal here is not necessarily to hide P2P nodes - we still need lots of clearnet P2P nodes for the forseeable future no matter what. Rather we're just using hidden services as a way to get authentication and encryption. Actually the 6-hop hidden service circuits are overkill for this
