Bitcoin is fungible
as much as ice is warm
My node values all sats equally
which is math. that does not make it fungible
If a business doesn’t accept certain denominations of bills does that make all cash non fungible ?
They are interchangeable therefore they are fungible
your own coins are interchangeable with each other. that does not make bitcoin fungible. i give you an example: you could own a bitcoin in your utxo which was used by another person for buying a fake id on onion and it is marked. in some situations it would be treated differently than a freshly mined or bought btc because it is clearly trackable and traceable. the good thing with bitcoin and any other decentralized coin is that it cannot be confiscated or stolen (if you self-custody and know how to protect it). but it is not fungible and as such it is not interchangeable and not treated equally, you could face some problems in acceptance in certain places. a fungible coin can fix this
Bitcoin is fungible on the protocol level, but is not fungible in practice in the real world because it's history is not private. Public history is an attack surface.
We can have pockets of fungibility within Whirlpool, but as a whole it is not fungible.
Is our goal p2p digital cash?
If I hand you a $100 bill, you only see our immediate transaction. Unless I choose to reveal where I got it from (default privacy) and even then I can only reveal my own history with the bill (view key).
