How can I create a p2sh transaction with a scriptsig containing OP_TRUE only, removing the need for a digital signature, which will be broadcasted and mined?

Also could some one provide an example of such a transaction?

  • @Michael Folkson I see the tag bitcoin-core-development was added by you, but I don't understand how it's related to the question, can you explain?

  • @VojtěchStrnad: Not sure, it was a while back! Think I thought it was functional test related but removed now :)

Here you have an example of a transaction spending from a P2PKH output and creating a P2SH output with an OP_1.

And here you have the counterpart, a transaction spending from the first one (with an input script '0151') and generating a P2PKH output.

I've created both using a Python library i'm coauthor of. You can check it out here.

  • I've added new transactions including fees to ensure that they end up in a block.

  • Does the output script you use to fund the p2sh transaction always have to be OP_HAS160 (hash) OP_EQUAL ?

  • Yes, that's the structure of any P2SH output script.

  • Could a transaction like that be created on the mainnet?

  • Sure. However you should be careful, anyone will be able to redeem it.
