Said Achmiz comments on What are reliable ways to make a statement in such a way that I will be able to prove in the future that I had made that statement?

OriginStamp is a Bitcoin-based service that seems to be solid.

It’s used by, for example, namespace’s Project Registration Database. (I built a custom PmWiki plug-in for this purpose, that allows any wiki page (or any wiki page you want) to automatically be OriginStamp’d upon creation. I haven’t released the code yet, but if anyone’s interested, I will.)
