Privacy Coins Beyond Monero: Zcash Shielded, Pirate Chain and Beam in the Darknet Settlement Economy

The tradecraft of darknet settlement is a moving target. For years, the playbook was simple: tumble your Bitcoin, pray the mixer wasn’t a honeypot, and move on. Those days are gone. The collapse of major mixing services and the increasing sophistication of chain analytics firms have pushed the ecosystem toward privacy-native assets. Monero XMR is the undisputed standard, but it is no longer the only game in town. For researchers and operators tracking the settlement economy, the interesting action is now in the alternatives-specifically Zcash Shielded transactions, Pirate Chain, and Beam. These protocols offer different trade-offs in privacy, liquidity, and operational security, and understanding those differences is critical for anyone assessing the long-term viability of the darknet financial infrastructure.

The Monero Baseline: Why It Still Dominates

To understand the alternatives, you have to understand the incumbent. Monero’s rise to dominance wasn’t accidental. Its architecture, rooted in the CryptoNote protocol, was designed from the ground up to obscure transaction details. Unlike Bitcoin, where every address and amount is broadcast on a public ledger, Monero uses ring signatures to mix a sender’s output with decoy outputs, ring confidential transactions (RingCT) to hide amounts, and stealth addresses to protect recipients. These features are enabled by default, meaning users don’t have to make a choice to be private-it’s just how the network works.

The data backs up its adoption. On-chain data from 2024 and 2025 shows Monero transaction volumes remained significantly higher than in the 2020-2021 period, stabilizing at an elevated baseline. This isn’t speculative hype; it’s sustained, regular demand. Even after a wave of exchange delistings in 2024-2025, trading migrated to decentralized and peer-to-peer platforms, which actually reinforced its utility for darknet purposes. Analysts tracking the now-defunct Abacus market noted that excluding Monero, total sales volume was estimated at $300 million to $400 million, with the platform’s heavy reliance on the coin reflecting a broader trend. Nearly half of all newly launched darknet markets in 2024 accepted only Monero, up from roughly one-third in 2023. The logic is simple: its untraceable design forces law enforcement to rely on operational security failures rather than on-chain analysis.

But Monero isn’t perfect. The April 2017 research highlighting threats related to zero ring size outputs and amount disclosure showed that even the strongest privacy coin requires careful usage. And there’s a centralization of risk: when everyone uses the same asset, the entire ecosystem’s liquidity is tied to that asset’s stability and acceptance. That’s where the alternatives come in.

Zcash Shielded: The Untapped Utility

Zcash is frequently mentioned in the same breath as Monero, but its privacy model is fundamentally different. Instead of hiding everything by default, Zcash offers a transparent ledger and an optional shielded pool. The shielded transactions rely on zk-SNARKs, a zero-knowledge proof method that allows a transaction to be verified without revealing its origin, destination, or amount. This was a direct evolution of the Zerocash protocol announced by Matthew Green in 2013, which reduced transaction sizes by 98% compared to the earlier Zerocoin protocol, though it was significantly more computationally expensive-initially taking up to 3.2 GB of memory to generate proofs, later reduced to 40 MB.

In the darknet context, Zcash shielded transactions (using a z-address) offer several distinct advantages. First, the succinct proofs are under 300 bytes and can be verified in milliseconds, making them technically efficient. Second, because the transparent pool exists, liquidity flows are less constrained than in fully-private networks. A vendor can accept Zcash transparently from a payment processor and then sweep funds into a shielded z-address for cold storage, breaking the chain of custody at a specific, deliberate point.

The catch is the trusted setup. Unlike Monero, which never required a ceremonial parameter generation, Zcash relies on a initial setup by a trusted entity. The original ceremony was multi-party, but the cryptographic foundation is a point of theoretical vulnerability. For high-stakes operators, the question is whether the risk is acceptable. In practice, the shielded pool has failed to achieve the same critical mass as Monero on darknet markets, but that doesn’t mean it’s absent. It’s often used as a secondary layer-a way to convert value from a Bitcoin or Litecoin payment rail into a private asset without touching Monero directly, creating a more complex trail for investigators to untangle.

Pirate Chain (ARRR): The Hardcore Option

If Monero is the default and Zcash is the nuanced utility, Pirate Chain represents the ideological fringes of privacy. Pirate Chain is a fork of Komodo (which itself is a fork of Zcash), and it enforces privacy at the protocol level. Unlike Zcash, where shielded transactions are optional, Pirate Chain makes all transactions shielded. There is no transparent pool. If you want to use ARRR, you are using z-addresses or you aren’t using the network at all.

This all-or-nothing approach has a certain appeal in the darknet settlement economy. It eliminates the risk of a user accidentally sending funds to a transparent address-a common OPSEC failure that plagues Zcash users who sometimes get careless with address types. The trade-off is liquidity. Pirate Chain is a smaller network with thinner order books and fewer merchant integrations. That makes it less practical for high-volume settlement but potentially more suitable for specific, value-dense transfers where the sender and receiver have established a direct relationship outside the marketplaces.

It’s worth noting the historical context here. The Zerocoin protocol, which preceded Zerocash, was designed with a simpler privacy model but suffered from cryptographic flaws discovered in April 2018 that could allow an attacker to destroy coins, create coins out of thin air, or steal user funds. The Zcoin team acknowledged the flaw but downplayed the economic incentive to exploit it. This history underscores a general principle: privacy coins built on complex cryptographic assumptions carry implementation risk. Pirate Chain’s lineage traces back to that same zk-SNARK family, so despite its hardened posture, it inherits the same theoretical scrutiny.

Beam: The MimbleWimble Contender

Beam takes yet another approach, built on the MimbleWimble protocol. MimbleWimble is distinct from the CryptoNote and zk-SNARK families in that it doesn’t use ring signatures or zk-proofs in the traditional sense. Instead, it relies on transaction aggregation and cut-through, where intermediate transactions are removed from the blockchain, leaving only the net effect of all transactions. This inherently hides amounts and makes the blockchain far smaller and more scalable. Beam also uses a Dandelion++ propagation protocol, similar to Monero, to obscure the IP addresses of transaction originators.

From a darknet perspective, Beam’s strength is its compactness and speed. The lack of a massive, complex ledger means faster sync times and lower fees. Its weakness is network effect. Acceptance of Beam on major markets is virtually nonexistent compared to Monero. It exists on the periphery, used by privacy enthusiasts and some vendors who prefer its specific operational characteristics. For a buyer, the friction of acquiring Beam-which typically involves swapping from Bitcoin or Monero through a decentralized exchange-might not be worth the effort unless there is a specific reason to avoid the more mainstream privacy assets.

Practical Considerations for the Darknet Economy

So how do these assets actually fit into the settlement economy in 2026? Based on market trajectories and the collapse of platforms like Abacus, a few patterns emerge.

• Monero XMR is the settlement layer. The sheer volume and liquidity make it the default. If a market only accepts one currency, it’s Monero. If a market accepts two, the second is usually a stablecoin for fiat-denominated transactions, with Monero serving as the privacy buffer.
• Zcash shielded is the bridging tool. Use it when you need to move value from a transparent rail (like Bitcoin exchanged via a P2P service) into a private context. The ability to selectively disclose is a double-edged sword: it can be used to prove payment to a third-party arbitrator, but it can also be a liability if you accidentally disclose the wrong view key.
• Pirate Chain and Beam are niche instruments. They are unlikely to replace Monero in the near term, but they serve as a hedge against the theoretical risk of a Monero-specific cryptographic break or regulatory ban that goes beyond exchange delistings. In the event of an existential threat to Monero, these networks are the likely beneficiaries of a migration wave.

There is also the law enforcement angle. The Abacus collapse highlighted how markets fail: withdrawal delays, DDoS attacks, and exit scams. But the use of Monero forced LE to shift their focus from blockchain tracing to infiltrating operations and seizing servers. For the alt-privacy coins, the same rule applies. The chain isn’t the vulnerability-the user’s behavior is. The market’s reliance on Monero has created a monoculture, but the alternatives provide an escape hatch, not a replacement.

Researchers should track the shielded pool usage on Zcash and the transaction count on Pirate Chain and Beam. A sudden uptick in either would signal a significant shift in confidence away from Monero. Until then, treat these assets as what they are: important components of a diversified privacy toolkit, each with its own strengths and operational quirks. The key takeaway is that privacy is not a feature-it’s a discipline, and the choice of coin is only the first decision in a long chain of OPSEC-relevant actions.
