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