Ignoring prefixes the cost for each reusable address is only a small

I'd point out that regardless of how long the desired prefix is, the
encoded prefix should probably always be constant length in all
reusable addresses.
I might be misunderstanding, but I think prefix length must

Like any other mechanism that puts extra data in the blockchain, the

This mechanism is to improve privacy for static addresses (donation
links on websites and so on). I personally don't think it will be used
nearly as much as BIP0032 or the payment protocol (both of which
But I think it's great people can choose how to trade privacy for
computation/bandwidth however they want, and services can compete to
offer monitoring for 0+ bit prefixes.
Its not a decision with user localised effect. If most users use it with

I was meaning to comment on the SPV privacy properties.
For full-node use these unlinkable static addresses have quite nice
properties. It also nicely solves the problem of having to educate users
