I wanted to use<br/>GNU guile scheme to experiment with bitcoin. I initially started by<br/>creating a toy bitcoin miner but I&#39;ve run into some inconsistencies with<br/>the documentation found on<br/><a href="https://en.bitcoin.it/wiki/Getblocktemplate">https://en.bitcoin.it/wiki/Getblocktemplate</a>. Namely with creating the<br/>templates merkle root.<br/><br/>&gt;From my understanding a coinbase transaction should have the<br/>transactions data concatenated before creating the merkle root. But<br/>getblocktemplate does not have a json cointbasetxn field. So I&#39;m not<br/>sure how to create a coinbase transaction without that.<br/><br/>I have a test template response data found here.<br/><a href="https://raw.githubusercontent.com/mrosset/prospect/master/test-suite/data.json">https://raw.githubusercontent.com/mrosset/prospect/master/test-suite/data.json</a><br/>and using a modified version of the merkle python reference script found<br/>on the wiki page. see<br/><a href="https://github.com/mrosset/prospect/blob/master/scripts/merkle.py">https://github.com/mrosset/prospect/blob/master/scripts/merkle.py</a> . I&#39;m<br/>able to create a merkle root with the hash<br/>c5fff939f628a04428c080ed5bd7cd9bc0b4722b2522743049adb18213adf28a but<br/>that&#39;s minus the coinbase transaction.<br/><br/>So far I&#39;m able to replicate this hash using the test data in guile. But<br/>I&#39;d like to sanitize this so that I&#39;m using a coinbase transaction and<br/>making sure the python and guile merkle roots match.<br/><br/>In short how do I get the coinbase transaction without the coinbasetxn<br/>field existing?<br/><br/>Mike 2023-06-07T22:59:08Z
