The reuse problem is, I think, better solved by the presentation of stealth address proposals, and would be handled by a stealth BIP (BIP 63) which has been recently re-discussed here: https://bitcointalk.org/index.php?topic=3D1083961.0 On 03/26/2015 02:44 PM, Gregory Maxwell wrote: > On Thu, Mar 26, 2015 at 9:26 PM, Tom Harding =20 > wrote: >> I should have been clearer that the motivation for address=20 >> expiration is to reduce the rate of increase of the massive pile=20 >> of bitcoin addresses out there which have to be monitored >> forever for future payments.
