Optional config file setting for linearize-hashes:

• RPC: host, port
• Block chain: min_height, max_height

Step 2: Copy local block data

$ ./linearize-data.py linearize.cfg

Required configuration file settings:

• "input": bitcoind blocks/ directory containing blkNNNNN.dat
• "hashlist": text file containing list of block hashes, linearized-hashes.py output.
• "output_file" for bootstrap.dat or "output" for output directory for linearized blocks/blkNNNNN.dat output

Optional config file setting for linearize-data:

• "netmagic": network magic number (default is 'cee2caff', testnet)
• "genesis": genesis block hash (default is '00000bafbc94add76cb75e2ec92894837288a481e5c005f6563d91623bf8bc2c', testnet)
• "max_out_sz": maximum output file size (default 100 * 1000 * 1000)
• "split_timestamp": Split files when a new month is first seen, in addition to reaching a maximum file size.
• "file_timestamp": Set each file's last-modified time to that of the most recent block in that file.
