Where can I learn more about OP_RETURN?

...

I am interested in learning more about the rapidly growing subject of posting data on the blockchain via the OP_RETURN function, but I have been unable to find much information (even less that non-programmer OROBTC can understand).

I also understand that using OP_RETURN is controversial due to concerns about "blockchain bloat", and that the blockchain is mainly used for posting financial transactions.

Thank you and much obliged for any info (links) for us beginners!

You can start by looking at the Bitcoin.it wiki Script section: https://en.bitcoin.it/wiki/Script - Their is some information I saw here regarding OP_RETURN

This question probably would get better attention if you had asked it in the Development & Technical Discussion board.

Here is a stackexchange question about op_returns:

This is a very interesting subject, you can look at the https://github.com/coinspark/php-OP_RETURN project very interesting and pretty easy to setup.

I learnt a few things from this link: http://wlangiewicz.com/blog/2014/10/24/how-to-put-custom-messages-into-bitcoin-blockchain-op-return/

Thank you very much for the links.  Clearly I now have some work to do to learn more.

This is a subject worth keeping an eye on.  Someone will likely make a lot of money.
