I want to build a services that allows people to perform OP_RETURN for proof of existence. Do I need to run a full node to do this (then e.g. using the OP_RETURN PHP scripts from https://github.com/coinspark/php-OP_RETURN)? I have found no API that allows to do this.

Thanks Chris

You do not need to run a full node in order to submit a transaction, regardless of which OP codes that transaction contains. Any node that can submit transactions to the Bitcoin network will do.

What you should look for instead, is a library in your chosen language that allows you to construct transactions manually, rather than using templates for typical payment transactions. Once you have a transaction constructed, you can broadcast it to the network via whichever type of node you feel like.

  • thanks! So is there a predefined list of bootstrap IP addresses or do I have to define a node to connect to? – Chris Oct 3 '16 at 17:48

    @Chris, this may help: bitcoin.stackexchange.com/questions/14371/… Also, you may want to run a full node anyways, if you are trying to start a service on top of Bitcoin. It's best to rely on your own node of the network, rather than someone else's. – Jestin Oct 3 '16 at 17:58
