Why not checking it now?

You can read it offline using (slightly modified) bitcoin-tools (patch included):

$ bitcoind stop
$ mkdir -p /tmp/bitcoin-block-snapshot
$ cp ~/.bitcoin/blk* /tmp/bitcoin-block-snapshot
$ wget
$ tar xfz msgdump.tgz
$ cd btcmsg-tools
$ python –datadir=/tmp/bitcoin-block-snapshot –transaction=72e78a410caf245e18ec9ee04d2e478c1e68f5eb8503d34ff69589a07aaa3cd1
In the beginning God created the heavens and the earth. Now the earth
was formless and empty, darkness was over the surface of the deep, and
the Spirit of God was hovering over the waters.
And God said, “Let there be light”.

[ANNOUNCE] Bitcoin message service v1.0 (within block-chain)

There are great news today!

Now you canย write your message into the bitcoin block chain.

The procedure is:

  1. Write your message.
  2. Click the “send email” button that creates a request. Send this request.
  3. Pay the _exact_ amount of BTC to the given account.

Your message will be part of the block-chain within few blocks, which means instantly thousands of copies all around the globe forever.

  • No registration required.
  • Totally anonymous if wanted.
  • Open protocol and basic python tools are included.
  • Offline option.
  • Client is signed to verify authenticity.

Basic technical details:
The clients are html+css+javascript only, and they are enough to read the messages forever (you can save the client locally for offline use).
The service for writing new messages requires the availability of an appropriate server, but the already processed messages are accessible forever, and some are already present on your copy of the block chain.
In order to write a new message, the clients create an email request which the server then processes.
The server is a special customised bitcoin setup behind tor.
