Scheduled Block Checker for Cardano Stakepool Operators

Lightweight and Portable Scheduled Blocks Checker for Current Epoch. No cardano-node Required, data is taken from blockfrost.io

Note: This is a reworking of old python script leaderLogs.py available on https://github.com/papacarp/pooltool.io.git

Prerequisites:

  • Python 3.8
  • pip (Python package installer)
  • libsodium library

Setup:

  • clone this repository using git: git clone https://github.com/adasnakepool/ScheduledBlocks.git
  • execute inside the newly cloned directory: pip install -r requirements.txt to install all needed python package requirements
  • get a project id on blockfrost.io
  • make sure you can access your vrf.skey file (you can copy in it a path of your choice) and remember to keep it as read only chmod 400 vrf.skey
  • copy the config.yaml.default into a new file and call it config.yaml (do not remove the default if you want to update the script via git pull in future)
  • open the newly created config.yaml and configure the settings accordingly:
    • timezone: your timezone (default: "Europe/Berlin")
    • blockfrost_id: project id from blockfrost
    • pool_id: your pool id. You can get it from adapools (it's the last part of the url)
    • pool_ticker: your pool ticker
    • vrf_key: "the path (relative or absolute) to the vrf.skey file

Usage:

python3 ScheduledBlocks.py

Output:

  • a console output with all the slots assigned for the latest available epoch
  • a SQLite database called: slotschedule.db which contains the slots assigned for every epoch the tool has been run.

  • false output when using next option

    false output when using next option

    Hi there, I use this fantastic tool as it's much lighter on my node, but recently when I use the next option it has given me false information. on 2 occasions the next option stated we had a block assigned but when I run it again during the epoch using the current option it states I dont have a block assigned.

    I'm not sure if this is updated anymore but id love if this tool could be maintained for the upcoming Vasil fork etc
