I though OP_RETURN looks something like this: https://blockchain.info/address/1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

As I mentioned you, avowal will be available as long as is bitcoin blockchain. Thank you Satoshi !

That is a common misconception. The public note displayed by blockchain.info is not part of the transaction. When you send bitcoins from blockchain.info, you can also attach a public note. This note is stored by the site and displayed along with the transaction. It is not stored in the block chain, so you can only see it on blockchain.info (unless another site scrapes the site).

There are various ways to store arbitrary data in a transaction. The best way is to use the OP_RETURN instruction, which is specifically designed for that purpose.

btw, it is better to link to the transaction rather than the address because subsequent transactions will eventually push the transaction (and the public note) off the first page.

If you use an OP_RETURN instruction does it show up on blockchain.info?
