Loading the DB
Use Rusty's bitcoin-iterate to generate text records and process:
/usr/local/src/bitcoin-iterate/bitcoin-iterate \
--quiet \
--blockdir /mnt/t5/blocks \
--block=B:%bN \
--input=I:%ih:%ii \
--output=O:%th:%oN:%oa \
| ./load | tee output.log
The loader will create a list of root block hashes in roots.txt.
Generate a proof
The proof generator takes root_hash, txid and index as args:
./prove \
