I want to understand how the number of Cardano stake pools developed over time. I am running cardano-db-sync. I thought the pool_update
and pool_retire
tables would give me this information.
My idea was the following: Whenever I see a hash_id
for the first time in the pool_update
table I would count that as a stake pool being created. Whenever I would see a hash_id
in the pool_retire
table I would count this as a stake pool being removed.
However, I come up with a higher number of stake pools when compared to what I can see on https://adapools.org/ (~2,000 pools).
How can I get the correct numbers over time?
