Decentralized no, but free and scriptable yes<p>E.g. <a href="https:&#x2F;&#x2F;startssl.com&#x2F;?app=25#61" rel="nofollow">https:&#x2F;&#x2F;startssl.com&#x2F;?app=25#61</a><p>Decentralized not usable in a legal context in any jurisdiction I can think of, and why do you timestamp if not to cover your ass?
