Hi Emin

This is going into the right direction. Well done!
The certificates (X.509/p12) are far more enduser-friendly than just a
normal PoE hash.

Your site needs some UX love and i just tried to OR_RETURN a
Email-Address-Verification. But after creating a 0.0001 tx and waiting
for two confirmations it still said that the payment has not yet been
received. There is probably something broken regarding the bitcoin
payment verification.

The weather and real estate notarization definitively needs a „US
only“ badge somewhere.

Two ideas:
- - Maybe adding a way of decentralize your notary service log via a
opensource p2p daemon (obviously sensitive data should be somehow
encrypted)?
- - Adding a opensource UI app to examine certs (maybe offline capable
with p2p daemon chain as mentioned above). This could prove
independence from your website/service.

Hi everyone,

Given the recent discussions on projects that use the Bitcoin blockchain to
record factoids, people on this list might be interested in the Virtual
Notary project. Virtual Notary is essentially an online witness (aka
attestor) to online factoids. It can provide:

  * proof of Bitcoin funds (without revealing public addresses or fund
location on the blockchain)

  * proof of Bitcoin address ownership

  * proof of Tweet

  * proof of real estate value

  * proof of DNS ownership

  * proof of existence

  * proof of web page contents

  * proof of weather conditions

The factoids can be recorded on the blockchain (if you pay for the
transaction with Bitcoin or PayPal), or they can be part of a free
attestation chain that we maintain. The website provides a permanent URL to
the factoids it generates; it also provides an X.509 certificate that you
can download and keep safe in perpetuity, independent of the website.

The link to the website is here:
  http://virtual-notary.org

The link to the writeup describing the various factoids and their use cases
is here:
  http://hackingdistributed.com/2013/06/20/virtual-notary-intro/

We are actively looking for people who are interested in developing the
service further. Specifically, if you have suggestions for how to extend
the service, for new proof/factoid types, or for how to build a business
case around the core idea, please let us know.

Best,
- egs
