...
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!
