Bitcoin Mempool Statistics
This is the code to create the mempool statistics for bitcoin that are online at https://jochen-hoenicke.de/queue/
Installation: Part 1 - Logging
You need to be running a bitcoin full node. It can be a pruned node or an archival node. I assume you have already set it up. You also need to support RPC to this node. Add rpcuser/rpcpassword to bitcoin.conf to enable this.
I recommend to create a new user mempool
. Checkout this repository into
his home directory:
sudo -H -u mempool bash
cd $HOME
git clone https://github.com/jhoenicke/mempool
Edit mempool.sh
to adapt paths as necessary, especially the path to
bitcoin-cli. Add a bitcoin.conf with rpcuser/rpcpassword settings to
/home/mempool/.bitcoin
, to be able to use bitcoin-cli. You can test your
setup by running
bitcoin-cli getinfo
Install sqlite3
and create a new empty database. Then you can test your
configuration by running mempool.sh
sudo apt install sqlite3
cd mempool
sqlite3 mempool.s3db < mempool-create.sql
./mempool.sh
You are almost ready now. Check that everything works. There should be a
file mempool.log
containing one line of statistics. There should be
newly created files in /dev/shm/mempool
that contain the dynamic date the
webserver should serve. If everything looks fine add the following crontab
entry (using crontab -e
):
* * * * * /home/mempool/mempool/mempool.sh
Installation: Part 2 - Web service
Install a web server of your choice. For refreshing/zooming you need
php and php-sqlite. Then link/copy the web subdirectory to the web
root. Finally link to the dynamic js files in /dev/shm/mempool
.
cd $HOME/mempool/web/queue
sudo ln -s $HOME/mempool/web/* /var/www/html
ln -s /dev/shm/mempool/*.js $HOME/mempool/web/queue/
