Privacy Coins, Explained in 6 Minutes

Added: 2026-05-13

[00:00:00]Imagine your bank statement was public by  design. Searchable by anyone. What you paid, who you paid, when you paid them,  and where that money went next.

[00:00:13]That’s basically how many major public  blockchains work. The ledger is open, so anyone can verify transactions. You don’t  need a bank to vouch for what happened, because the rules are enforced publicly. But transparency comes with a tradeoff… Your name usually isn’t on-chain, but your wallet  address is. And once that address gets linked to you, even once, a lot of your activity can  become readable. Not just a single payment, but patterns across time. If you want privacy, that’s the problem privacy coins were built to solve. Privacy coins are cryptocurrencies designed to hide some of what public blockchains normally  reveal, like who paid who, how much was sent, or how funds moved over time. There are plenty  of projects in this category and they don’t all work the same way, but the goal is  consistent: make everyday transactions less traceable to the public internet. To see why that’s a big deal, it helps to contrast it with how Bitcoin-style transparency works. On a typical public blockchain, you usually see wallet addresses, amounts, and  the path funds take from one address to the next. That’s why Bitcoin is  sometimes described as pseudonymous, not anonymous. Identities aren’t shown  by default, but if an address ever gets linked to a person or company, the  history attached to it can reveal a lot.

[00:01:25]So privacy-focused designs try to reduce that  linkability. Most aim to hide at least one of four things: the sender, the receiver, the amount,  or the ability to follow the trail over time.

[00:01:39]Now, privacy isn’t automatically about wrongdoing.  In normal finance, confidentiality is expected.

[00:01:46]Most people simply don’t want strangers  tracking their personal spending and payments.

[00:01:51]But regulators draw a line at anonymity that makes  transactions extremely hard to trace. Not because they want everyone’s finances public, but because  financial systems can be abused. Think scams, ransomware, or fraud. When tracing gets  harder, enforcement gets harder too.

[00:02:14]That’s where anti-money laundering rules come  in. In traditional finance, banks and payment firms are required to verify customers, monitor  suspicious activity, and keep records. As crypto becomes more mainstream, those expectations  land on regulated crypto businesses too, like exchanges and other service providers.  So if a coin’s design makes meeting their obligations challenging, it’s common to see  restrictions and even delistings in some regions.

[00:02:44]For example, Kraken ended support for  Monero in the European Economic Area due to regulatory changes. And from 2027,  the EU’s Anti-Money Laundering Regulations will restrict anonymous crypto-asset accounts,  or those that allow anonymisation, including through what it calls ‘anonymity-enhancing coins.’ So how can privacy coins fit into a world where people want confidentiality, but authorities  still need to investigate serious wrongdoing?

[00:03:16]Two of the most well-known examples, Monero  and Zcash, show two different philosophies.

[00:03:22]Monero is privacy by default. Privacy  is baked into standard transactions.

[00:03:28]Zcash takes a different approach. It  says privacy can be a choice. It supports transparent transactions, where details are  visible on-chain like any public ledger. But it also supports shielded transactions,  where sensitive details are protected.

[00:03:46]And that “choice” matters for two reasons. First, it’s practical. Not every payment needs maximum privacy, and sometimes  transparency is actually useful, like public reporting, donations, or when you  just want transactions to be easy to verify.

[00:04:05]Second, it opens the door to privacy with proof.  Zcash supports selective disclosure through viewing keys, which let you share visibility  into shielded transactions with a trusted party without giving them control of your funds. Private  from the public internet, but still possible to show receipts when you genuinely need to. And if you’re wondering how a network can validate a shielded transaction  if the details aren’t public, that’s where zero-knowledge proofs come in. In simple terms, they let the network confirm a transaction is valid without  revealing the private details behind it.

[00:04:43]The rules can still be enforced, like making  sure the funds exist and aren’t double-spent, without turning the transaction into public data. It's like an age check. Normally, you show your ID, but that reveals far more than  necessary. A zero-knowledge proof is like proving "I'm over 21" without revealing  your name, address, or exact birthdate.

[00:05:06]And that’s the real battle here. People want  digital money that doesn’t turn their financial life into a public record, while regulators  want a system where users can be protected and wrongdoing can still be investigated. But these don't have to be opposing goals.

[00:05:24]The answer likely isn't absolute anonymity,  but something that respects user privacy by default, with the possibility  of accountability when needed.

[00:05:35]It’s a fine line. Too much transparency and  you lose the financial privacy most people expect. Too little, and you end up with systems  that struggle to operate in regulated markets.

[00:05:48]So where do you stand? Is  selective disclosure the answer, or is privacy ‘all or nothing’?  Drop your thoughts in the comments, and let us know if any privacy-focused  projects are on your radar for 2026.
