|
|
|
Construct a linear, no-fork, best version of the blockchain.
|
|
|
|
|
|
|
|
|
|
## 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": bootstrap.dat
|
|
|
|
|
or
|
|
|
|
|
* "output": output directory for linearized blocks/blkNNNNN.dat output
|
|
|
|
|
|
|
|
|
|
Optional config file setting for linearize-data:
|
|
|
|
|
* "netmagic": network magic number
|
|
|
|
|
* "max_out_sz": maximum output file size (default 1000*1000*1000)
|
|
|
|
|
* "split_year": Split files when a new year is first seen, in addition to
|
|
|
