If you delve deep enough: the privacy of any cryptocurrency using Pedersen Commitments as cryptographic primitive is DOA because PCs are neither public key rerandomizable nor pk updatable. This forces UTXO & single use outputs downstream, which leak patterns even zero knowledge proofs can’t hide

TLDR: Any form of digital cash using Pedersen Commitments as cryptographic primitive is not private. Pedersen Commitments force some architectural decisions that make any form of digital cash that uses PCs as cryptographic primitive to hide amounts inherently traceable because PCs allow the construction of a transaction graph, despite hidden amounts.
