Topic: Problems with the linearize.py script (Read 1164 times)
If you want to download another copy of the blockchain through the Bitcoin network (which can be from another local bitcoin of yours), you can use https://github.com/jgarzik/pynode. It is a Python standalone Bitcoin node with limited functions. It has a script, mkbootstrap.py, which will also generate the torrent file.
I finally managed to obtain the bootstrap.dat file. I had to:
Thank you for the help.
- create bitcoin.conf with server=1
- set rpcuser/rpcpassword variables in both bitcoin.conf and linearize.cfg
- set max_height=295000 in linearize.cfg
- restart Bitcoin-Qt
- run linearize.py
Thank you for the help.
linearize.py gets blockchain data from bitcoin core using JSON-RPC calls. it does not read it from disk.
I don't have a bitcoin.conf file in my home directory. I also don't understand what linearize.py is trying to connect to, as the blockchain data is on my hard disk. Should I run bitcoind instead of Bitcoin-Qt? Sorry but I'm quite confused...
it should be pretty obvious
it probably means you don't have server=1 in bitcoin.conf (since you're running bitcoin-qt rather than bitcoind)

Hello. I'm a new forum user, but have been using Bitcoin itself for a few months. I read here that I can obtain the bootstrap.dat file via Bittorrent, but since I already downloaded the blockchain data via Bitcoin-Qt I guess it's better to generate the file with the linearize.py script and then seed it. But I get the following error when running it:
I don't know Python so I can't understand what's wrong. I just edited the max_height variable in example-linearize.cfg before running the script:
Code:
