<p>I am facing two problems below,</p>

<p>First is that I am trying to broadcast transaction which have OP_RETURN but blockchain.info continuously rejecting it, though I have broadcast it using bitcoind.</p>

<p>Second is that what is the best way to insert an OP_RETURN data into the raw transaction. Currently I am following this method ---> <a href="https://bitcoin.stackexchange.com/questions/25224/what-is-a-step-by-step-way-to-insert-data-in-op-return/36439#36439">What is a step by step way to insert data in OP_RETURN?</a></p>

<p>but i know this is not a standard way.</p>

Blockchain.info doesn't know how to understand OP_RETURN outputs. Just because one website isn't showing it doesn't mean it hasn't made it around the network.

I'm the guy who wrote the answer that you're linking to. I'm having trouble understanding your second question. Are you asking if it's still a good method?

@Bitcoin I think he means that blockchain.info/pushtx didn't work.

@NickODell Same response really, blockchain.info doesn't understand OP_RETURN transactions and won't relay them through that interface as a result.

# Broadcasting an OP_RETURN transaction

(Asked by: username_0 on 2015-07-11)

I am facing two problems below,

First is that I am trying to broadcast transaction which have OP\_RETURN but blockchain.info continuously rejecting it, though I have broadcast it using bitcoind.

Second is that what is the best way to insert an OP\_RETURN data into the raw transaction. Currently I am following this method ---> [What is a step by step way to insert data in OP\_RETURN?](https://bitcoin.stackexchange.com/questions/25224/what-is-a-step-by-step-way-to-insert-data-in-op-return/36439#36439)

but i know this is not a standard way.

I am using php and bitcoind server!

Any help would be appreciated :)

Thanks

Blockchain.info does not display transactions with OP\_RETURNs until they are confirmed on the blockchain.

You can view all recent OP\_RETURN transactions on [Coin Secrets](http://coinsecrets.org/), and there's a link from there to a simple PHP library for working with OP\_RETURNs.
