title: How do I mine LBRY credits?
category: mining
---
Library Credits (LBC) are mined over a 20-year Proof of Work period.
Block rewards increase every 100 blocks by 1LBC, peak at 500, and decline slowly.

For GPU mining, please see our list of [pools](https://lbry.io/faq/mining-pools). Each pool has a slightly different setup so please check their Getting Started page.

For CPU mining, LBRY binaries are out for OS X and Ubuntu. Others may try compiling from source.

## Mining on Ubuntu

1. `wget https://s3.amazonaws.com/files.lbry.io/bins.zip`
1. `unzip bins.zip`
1. `./lbrycrdd -server -printtoconsole -gen`
1. If you need to start over, run `rm -rf bins.zip lbry* ~/.lbry*`. **Note:** this will delete your wallet and any credits you may have.

## Mining on macOS

1. `wget https://s3.amazonaws.com/files.lbry.io/osxbins.zip`
1. `unzip osxbins.zip`
1. `mkdir ~/Library/Application\ Support/lbrycrd`
1. `sudo chown -R "$(whoami)" ~/Library/Application\ Support/lbrycrd`
1. `echo -e "rpcuser=lbryrpc\nrpcpassword=$(env LC_CTYPE=C LC_ALL=C tr -dc A-Za-z0-9 < /dev/urandom | head -c 16 | xargs)" > ~/Library/Application\ Support/lbrycrd/lbrycrd.conf`
1. `./lbrycrdd -server -printtoconsole -gen`
1. If you need to start over, run `rm -rf bins.zip lbry* ~/.lbry ~/Library/Application\ Support/lbrycrd`. **Note:** this will delete your wallet and any credits you may have.
