Not sure why you uploaded a halving chart goof. That has nothing to do with input/outputs on chain.

You're relying on additional software by using (closed source Excel at that) to do this for you with it's own potential bugs or user error. That's not taking full advantage of Bitcoins transparency to audit.

Pressing a button and having software spit a number back at you is  no different than doing that with a Monero node 🤡
