A deep dive into cryptocurrency history, the concept of privacy coins, and the three currencies accepted on the platform — with a focus on why Monero stands apart as the privacy standard.
The concept of digital cash predates Bitcoin by decades. In 1983, David Chaum proposed a cryptographic electronic money scheme in his paper "Blind Signatures for Untraceable Payments." His company DigiCash attempted commercialisation in the 1990s but failed. E-Gold, another early attempt, was eventually shut down by US authorities in 2008.
In October 2008, an anonymous individual or group publishing under the pseudonym Satoshi Nakamoto released the Bitcoin whitepaper: "Bitcoin: A Peer-to-Peer Electronic Cash System." This document described a decentralised ledger — the blockchain — secured by cryptographic proof-of-work. The first Bitcoin block (the "genesis block") was mined in January 2009.
Bitcoin demonstrated that trustless, permissionless digital money was technically achievable. However, its transparent blockchain meant that all transactions were permanently public and traceable. Researchers at universities and privacy advocates quickly identified this as a significant weakness for users who required financial privacy.
This gap gave birth to the privacy coin ecosystem. Bytecoin (2012) introduced ring signatures. Its fork, Monero (2014), refined the technology and became the gold standard for private transactions. Zcash (2016) took a different approach using zk-SNARKs (zero-knowledge proofs). Dash, Grin, and others followed with varying privacy models.
Today, Nexus Darknet and similar platforms increasingly mandate or strongly incentivise Monero as the payment method of choice — a direct response to blockchain analytics firms like Chainalysis successfully de-anonymising Bitcoin transactions used in earlier marketplace generations.
Privacy coins are cryptocurrencies that implement cryptographic techniques to obscure transaction metadata — specifically the sender address, recipient address, and transaction amount. Standard cryptocurrencies like Bitcoin record all three pieces of information permanently and publicly on a transparent ledger.
Ring Signatures: Used by Monero. When a transaction is signed, the real signer's key is mixed with a ring of other public keys from the blockchain. An observer cannot determine which member of the ring actually signed — providing sender anonymity with cryptographic deniability.
Stealth Addresses: Also used by Monero. Instead of publishing a static receiving address, each transaction generates a one-time address on the recipient's behalf. An outside observer cannot link multiple payments to the same recipient even if they know the recipient's public address.
RingCT (Ring Confidential Transactions): Monero's mechanism for hiding transaction amounts. Uses Pedersen commitments to prove that inputs equal outputs without revealing the actual values.
Zero-Knowledge Proofs (zk-SNARKs): Used by Zcash. Allows one party to prove knowledge of information without revealing the information itself. Computationally intensive but mathematically elegant.
CoinJoin: A Bitcoin privacy technique that mixes multiple transactions together. Less robust than Monero's native privacy since participation is voluntary and patterns can sometimes be traced.
| Feature | Monero (XMR) | Bitcoin (BTC) | Litecoin (LTC) |
|---|---|---|---|
| Sender privacy | ✔ Ring Signatures | ✘ Public | ✘ Public |
| Recipient privacy | ✔ Stealth Addresses | ✘ Public | ✘ Public |
| Amount privacy | ✔ RingCT | ✘ Public | ✘ Public |
| Privacy by default | ✔ Always on | ⚠ Optional (CoinJoin) | ✘ No |
| Chain analysis resistance | ✔ High | ✘ Low-Medium | ✘ Low |
| Nexus recommendation | ★ Strongly preferred | ✔ Accepted | ✔ Accepted |
The gold standard for private transactions. Ring signatures hide the sender, stealth addresses hide the recipient, and RingCT hides the amount. Every transaction is private by default — no optional privacy modes, no selective disclosure.

The original and most widely-used cryptocurrency. Bitcoin's transparent ledger means transactions are traceable by default. Advanced techniques like CoinJoin, Wasabi Wallet, and Lightning Network can improve privacy, but are not enabled by default.
BTC Privacy Guide →
A Bitcoin fork with faster block times and lower fees. Like Bitcoin, Litecoin uses a transparent blockchain — all transactions are publicly visible. MWEB (MimbleWimble Extension Blocks) introduced optional privacy features, though adoption is limited.
LTC Privacy Guide →Multiple independent academic studies have confirmed that Bitcoin transaction history can be de-anonymised using blockchain analysis — even when mixed. The 2021 publication "An Empirical Analysis of Traceability in the Monero Blockchain" (Princeton) found that while early Monero versions had weaknesses, the modern Monero protocol with mandatory RingCT is significantly more resistant to tracing than any Bitcoin privacy technique.
Blockchain analytics firms including Chainalysis, Elliptic, and CipherTrace have publicly stated that Monero presents far greater analytical challenges than Bitcoin. In 2020, the US Internal Revenue Service offered a $625,000 contract specifically to crack Monero tracing — a strong indicator of its effectiveness.
For users of Nexus Onion and similar platforms, the practical conclusion is clear: Monero offers the strongest default privacy guarantee available in a mature, widely-adopted cryptocurrency. Bitcoin can be made more private through additional steps — but those steps add complexity and failure points that Monero eliminates by design.
