The output address of a transaction could basically have the last 4 char= acters used to signal support for a p= articular proposal.

To generate an address with 4 consecutive case-insensitive characters shoul= d be roughly 34^4 which is just over a million attempts. On typical hardwar= e this should take less than a second.

An example bitcoin address that wanted to support the core roadmap might be= :

or to signal support for a big block proposal might be:

Popularity could be measured weighted by fee&nbs= p;paid per voting kb.

Despite the limitations, I believe this offers a very accessible way to = immediately allow the entire economic community to signal their support wit= hin transactions. The only cost is that of a tiny hashing PoW that should t= ie up a CPU for a barely noticeable amount of time, and could be implemented relatively easily into wallet sof= tware.

While it could just be used for signaling support and giving users a 'vo= ice' on chain, if considered effective it could also be used to activate ch= anges in the future.


Any thoughts welcome.
