It has come to my attention that often times people in this sub forums make all sorts of claims but later have trouble proving it. After all, online forums can be hacked and these statements could easily be altered. Even the trusted third parties (escrow services) can become corrupt.
What is then recommended is storing the statement into the very block chain itself so that the whole Bitcoin network starts guarding the integrity of a given message. Additionally, the timestamp attached to the message can then be used to securely verify the date and time when the statement was created.
During the past 4 weeks I have been involved in the development of
http://CryptoGraffiti.info web service that allows to monitor the human readable messages stored into the block chain now and then. In addition, the service makes it easy to encode your own arbitrary message into Bitcoin addresses.
I created this topic here because I know personally that this issue has risen several times in this particular sub forum. The development thread is here:
