Privacy Coin Comparison: Zcash, Monero, Bitcoin and Dash

Compare evidence, not privacy scores

On small screens each project becomes a labeled row card. All values are qualitative source descriptions, not a measured anonymity ranking.

What counts as a privacy comparison

A meaningful comparison identifies the operation, observer and information disclosed. Receiving, spending, viewing records, crossing pools and using an intermediary are not interchangeable tasks.

An observer might see the public ledger, an endpoint, an exchange account or network metadata, and a protocol document does not automatically cover all of those views. We compare source-described mechanisms and evidence limits rather than a fabricated percentage of privacy.

Bitcoin is included as a public-ledger reference, not silently recategorized as an always-shielded privacy coin.

Zcash: receiver and pool scope must remain explicit

ZIP 316 distinguishes transfer-protocol receivers and Unified containers, and notes that a wallet can support the container while supporting only a subset of payment methods. ZIP 224 is an Orchard shielded protocol design reference, not a device test.

Ironwood and NU6.3 add newer deployment and wallet considerations that have their own source scope. A transparent transfer, a shielded transfer and a pool migration cannot share one unconditional anonymity statement.

Current support notices in the wallet directory remain important even when an older source mentions a capability.

Monero: separate the documented components

The saved Moneropedia stealth-address page describes one-time addresses created for recipients. The ring-signature page describes possible signers represented by public outputs, while RingCT is described as hiding transaction amounts.

These are different components rather than a single empirical assurance. The view-key documentation also states visibility limitations, including watch-only outgoing tracking.

This matrix reports the primary explanations, not an independently tested current protocol version or a reproduction of attack resistance. Historical dates within a glossary do not prove present implementation compatibility.

Bitcoin and Dash: transaction patterns are not shielded proofs

Bitcoin’s developer guide describes a public ledger and the risks of repeated public keys or addresses, along with practices such as CoinJoin and merge avoidance. Dash’s stable wallet page describes CoinJoin as a non-custodial sequence intended to make history reconstruction difficult.

These techniques must be represented on their own terms. Custody, traceability, public transaction visibility and endpoint disclosure are separate properties.

Neither a documented round count nor an address-reuse recommendation is a comparable numerical score against a shielded proof system.

How to use the matrix without overreading it

Start with the named mechanism and open its primary source. Check whether the passage is protocol-level, a mutable glossary, a developer guide or a platform-specific wallet statement.

Then inspect the source-check date and saved version. A missing capability in this small corpus is unverified, not universally unsupported.

If a current operational answer needs a particular app/firmware or activation block, this documentation matrix does not supply that test. The linked comparison guides explain each source pair in more detail without choosing an investment winner.
