Finding the longest attestation slot gap
Find the best slot gap to avoid missing any validator duties.
Find the best slot gap to avoid missing any validator duties.
The following steps align with our mainnet guide. You may need to adjust file names and directory locations where appropriate. The core concepts remain the same.
Your validators are assigned duties to attest and propose blocks.
Understanding the schedule of your validator's duties better, you can find the best time to plan consensus/execution client updates, system reboots or outages.
Since the Altair Hard Fork, checking sync committee membership is a must before performing any maintenance. This will give you up to ~27 hours of advanced notice in case your validators have been selected for sync committee duties.
python3
validator index number(s) -- Lookup on https://beaconcha.in/ or https://beaconscan.com/
Works with Lighthouse / Teku / Prysm currently
Kudos to pietjepuk2 on Discord for authoring this process.
1. Install python3
2. Download pietjepuk2's get_validator_duties.py
python script.
3. Enter your validator index numbers as parameters to the python script.
Sample Output showing the longest gap in seconds, # of slots and time range.
Longest gap (first):
120.0 seconds (10 slots), from 13:37:35 until 13:39:35
The python script calls the http API
on port 5052.
Ensure the http API
is enabled for your consensus layer client.
teku: --rest-api-enabled=true
Teku by default uses port 5051, rather than 5052. Search and replace the port number before using.
This version does not include block proposals, although the odds of having one scheduled are really low of course.
Block proposal duties are only known for the current epoch, whereas attestation duties are known for the current and next one.
Nice work. Now you now the best gap to avoid missing any validator duties.
Congrats on completing the guide. ✨
