🧗 Can you find the drop in ETH issuance per day?
New ETH is created and issued continuously as rewards to incentivize miners(validators) to secure the network.
Since validators use staked ETH to secure the network instead of mining, they no longer need to run expensive hardware. Hence, the rewards in PoS are lower than in PoW.

ETH issuance
Net ETH issuance = PoW Rewards (before merge) + Validator Rewards - ETH burnt
The validator rewards are stored in Beacon state. Since beacon state is not available in Dune analytics, we can approximate the daily PoS ETH issuance by computing the upper bound using the below formula:
Daily PoS issuance(upper bound) = no_of_epocs_per_day * ( effective_balance * base_factor * num_validators / sqrt(effective_balance * base_factor * num_validators)) where no_of_epocs_per_day = 225, effective_balance = 32ETH, base_factor = 64
