@cjmoles - Excellent link, appreciate reading all the wacky things people have done.

So does adding stuff slow down the transaction as well? I see it takes up more room but does it confirm slower!

Not possible. Anything can be cracked with enough motivation and know how.
There is evidence all over the internet you just have to know where to find it.

It can be done....and much more. But, my question would be: is there a more efficient way to send and preserve communications that wouldn't bloat the block chain ledger? There are several unnecessary messages already bloating the ledger (photos and quotes of Nelson Mandella, frivolous code...etc)1; however, there is some amount of utility to the practice such as; copyright posterity, identification verification, and such....

Short Question:
Alice and Bob want to tranfer a secret letter. How can they transfer the information with the use of the blockchain?
Thanks!

Why the need for the blockchain?
1) just a secret message transfer:
bob publishes his public key, alice encrypts the message to that key and sends to bob.
2) a secret message transfer with some deniability for both:
as in (1) except alice transfers encrypted message to a dropbox like mailinator
Use of a blockchain would be indicated if you wanted the message to remain around forever, immutable.
Do you really need this? Possibly you only need the hash of the message to be kept immutable forever?

this isnt the best method (mem limits), but yes, there are services like the aforementioned that can embed messages in the blockchain.
with that being said, much easier to publically blast a coded message (https://en.wikipedia.org/wiki/Numbers_station) or send an encrypted message. Hiding in plain site isn't the best choice for information that is highly sensitive.
as said above by odolvlobo and unamis76. but I think that's kind of impractical because Bob would have to know the transaction hash or having the transaction sent to his address. might as well go without the blockchain.
oh. and the "secret" letter can be seen by anyone that have the transaction hash. forever.

A small amount of information can be stored in the block chain using an OP_RETURN transaction.
And encrypting said message
One can use services like CryptoGraffiti to easily embed messages on the blockchain.
Is there any other token?
Other than Bitcoin, that's leveraging blockchain to transfer information?
