Pirate Chain (ARRR) is a privacy-focused proof-of-work cryptocurrency launched on August 29, 2018, within the Komodo ecosystem, that mandates 100% shielded (private) transactions using zk-SNARKs derived from Zcash’s Sapling protocol — meaning all transaction amounts, sender addresses, and receiver addresses are cryptographically hidden on-chain — with additional security provided by delayed Proof-of-Work (dPoW) checkpointing to the Bitcoin blockchain.
| Stat | Value |

| Ticker | ARRR |
| Price | $0.19 |
| Market Cap | $37.71M |

| Circulating Supply | 196.21M ARRR |
| Max Supply | 200.00M ARRR |
| All-Time High | $16.76 |
How It Works
- Mandatory shielded transactions — Unlike Zcash, where transparent transactions are possible, Pirate Chain enforces that all transactions use the shielded (z-address) pool. There are no transparent t-addresses in normal use.
- zk-SNARKs (Sapling) — Pirate Chain implements Zcash’s Sapling zk-SNARK protocol, which proves transaction validity without revealing amounts, sender, or receiver.
- Equihash mining — The coin uses the Equihash proof-of-work algorithm (same as Zcash), allowing GPU mining.
- Delayed Proof-of-Work (dPoW) — Inherited from the Komodo ecosystem, dPoW notarizes Pirate Chain block hashes onto the Bitcoin blockchain periodically, making deep reorganization attacks economically infeasible since an attacker would also need to rewrite Bitcoin’s chain.
- KomodoOceanQT wallet — Pirate Chain uses a custom desktop wallet with a built-in shielded address UI to ease the user experience for mandatory shielded transactions.

Use Cases
- Mandatory-private value transfer — All transactions are shielded; no option for transparent on-chain history.
- Mining — Equihash GPU mining for new ARRR.
- Store of value with privacy — Designed for users who require assured on-chain privacy without opt-in complexity.
History
- 2018-08-29 — Pirate Chain launched by a pseudonymous team within the Komodo ecosystem. No ICO, no premine. Mined from genesis block.
- 2018 — dPoW integration with Bitcoin provides additional 51% attack resistance by notarizing checkpoints on Bitcoin.
- 2020–2021 — ARRR gains attention in privacy coin communities as listings expand. Emphasized as having stronger privacy guarantees than Zcash due to mandatory shielded transactions.
- 2021 — ARRR reaches all-time high of approximately $13 in November 2021 during the broader bull market.
- 2022 — Listed on additional exchanges. Privacy coin regulatory scrutiny globally affects market positioning.
- 2023–2025 — Community-driven development continues. Pirate Chain is delisted from some centralized exchanges citing regulatory compliance concerns around privacy coins.
Common Misconceptions
“Pirate Chain is the same as Zcash.”
Pirate Chain uses Zcash’s Sapling zk-SNARK code but is a separate chain with key differences: all transactions are mandatory shielded (Zcash allows transparent transactions), there was no premine or founder’s reward (Zcash had a “Founder’s Reward”), and it uses dPoW for additional security.
“100% shielded means no traceability at all.”
zk-SNARKs hide on-chain data. However, network-layer surveillance (IP leaks, exchange KYC) and metadata analysis remain potential privacy leaks. Chain-layer privacy is complete; network-layer privacy requires additional measures (e.g., Tor).
Social Media Sentiment
Pirate Chain has a strong, ideologically motivated community that emphasizes financial privacy as a human right. It is regularly cited in privacy coin comparisons. It is controversial due to regulatory pressure — exchanges worldwide have delisted various privacy coins, and ARRR is often in that category. Supporters argue mandatory privacy is the only real privacy.
