# Linearize
Construct a linear, no-fork, best version of the blockchain.

## Step 0: Install neobytes_hash

https://github.com/neobytes-project/neobytes_hash

## Step 1: Download hash list

    $ ./linearize-hashes.py linearize.cfg > hashlist.txt

Required configuration file settings for linearize-hashes:
* RPC: rpcuser, rpcpassword

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.
Update linearize scripts. Break into two steps: * Generate hash list * Build data file(s) from local bitcoind blocks/ directory. This supports building one large bootstrap.dat, or multiple smaller blocks/blkNNNNN.dat files. 2014-08-24 03:46:12 +02:00			`# Linearize`
