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.

Hello again, I get this error when executing the script:

Traceback (most recent call last):
  File "ScheduledBlocks.py", line 258, in <module>
    firstSlotOfEpoch = (firstSlot) + (epoch - 211)*epochLength
NameError: name 'epoch' is not defined

Hope you find some time - again, thx you for your efforts.

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

Some Python Modules missing

Hello Snake, first of all, thx you so much for your efforts of (re)writing this script. I run into the following issue:

These modules need to be installed manually: pip install pytz pip install readchar
