About Firo
Firo is a privacy-preserving cryptocurrency and ecosystem. We stand out as one of a handful of projects that contribute independent research to blockchain privacy and decentralization technologies such as Zerocoin, Sigma, Lelantus, Lelantus Spark and FiroPoW. Our work has played a pivotal role in the space having influenced or been adopted in other projects.
Research
Lelantus Spark
Lelantus Spark greatly improves over its predecessor Lelantus with flexible Spark addresses that hide all transaction amounts while remaining undetectable on the blockchain. It supports threshold signatures, both incoming and outgoing view keys, with a modular design enabling future upgrades. No trusted setup required.

Extending Spark's privacy to tokenized assets, enabling private smart contracts and decentralized applications with built-in privacy.
Learn more →FiroPoW
FiroPoW is a modified version of ProgPoW 0.9.4 designed specifically for GPU mining. It includes a random sequence that changes every block to add further ASIC and FPGA resistance. Requires minimum 8GB VRAM, keeping older hardware off the network while remaining accessible to modern GPUs.
Technical details →Chainlocks
Our hybrid PoW and LLMQ Chainlocks system defends against 51% attacks while ensuring near-instant finality of blocks and transactions. This masternode-based consensus provides additional security without sacrificing decentralization, making Firo an ideal choice for secure and efficient payments.
How it works →Roadmap
Firo has come a long way since its inception as Zcoin, pioneering the use of modern zero-knowledge proofs in a privacy protocol. Over time, we have steadily iterated on our technology, developing some of the most robust privacy protocols in the space — protocols that have influenced many other projects.
Our updated roadmap focuses on usability, utility, and upgrades.
Usability
Enhancing the user experience, integrating with additional wallets, and supporting light clients.
Utility
Expanding use cases through private token issuance and implementing further privacy enhancements in preparation for future quantum computing challenges.
Upgrades
Continuously strengthening the protocol's core features to maintain Firo's position as a leader in privacy technology.
Near-term goals
Spark Names
Allow users to register human-readable addresses tied to their Spark addresses. This also enables storing and sharing metadata for potential use as a decentralized digital identity.
Spark Coinbase
Enable miners and masternodes to send rewards directly to private Spark addresses, further enhancing user privacy and Spark adoption.
View Key Tooling
Develop user-friendly methods for sharing and utilizing Spark view keys, enabling watch-only wallets and selectively disclosing Spark-based funds for compliance purposes.
Mid-term goals
Spark Assets
Allow users to issue their own privacy-preserving assets. These assets enjoy the same privacy features as Spark, including the ability to hide asset types. All assets (including Firo) contribute to a shared anonymity set, and the protocol can also support privacy-preserving NFTs.
Spark Swap
Enable atomic swaps between Spark assets and/or Firo, ensuring trustless and private exchanges.
Curve Trees
Adopt Curve Trees, an innovative technique for efficient membership proofs that supports a global anonymity set. This upgrade will substantially improve privacy, scalability, verification speed, and proof size.
Long-term goals
Improved Privacy-Preserving Light Wallet Infrastructure
Enhanced infrastructure to support privacy-preserving light wallets with better efficiency and security.
Quantum-Resistant Spark
Explore paths to transition Spark into a quantum-resistant protocol, as well as potential interim mitigations to safeguard against future quantum threats.
Tail Emission Consensus Mechanism
Firo's current hybrid masternode–Proof-of-Work model may evolve once tail emission is reached. We are investigating alternative incentive or consensus mechanisms to secure the chain in the long run.
Governance
Develop clear, decentralized governance structures to reduce reliance on Firo's core team. The aim is to align all project stakeholders without focusing solely on coin holdings.
Integrations
Enkrypt Wallet Integration
Integrate Firo into Enkrypt, a multi-asset Web3 browser extension wallet, with full support for Spark features.
Layerswap v8 Integration
Leverage Layerswap v8, a peer-to-peer protocol for bridging and swapping crypto assets across different blockchains. By using pre-HTLCs, it addresses many limitations of traditional atomic swaps (e.g., both parties needing to be online) and supports multi-hop transactions.
Serai Integration
Collaborate with Serai, a cross-chain DEX focusing on AMM liquidity for Bitcoin, Ethereum, DAI, and Monero. Integrating Firo expands its cross-chain liquidity options and user base.
Iterative Improvements
Campfire
Continue building out Campfire desktop and mobile wallets to provide full-featured support for masternodes, Spark Assets, and Spark Names.
FiroDEX
Rework FiroDEX to be more resilient, ensuring its infrastructure—both nodes and front ends—is operated by a decentralized network of volunteers and community members.
FAQ
What makes Firo different from other privacy coins?
Firo uses Lelantus Spark, a cutting-edge privacy protocol that provides high anonymity sets and flexible privacy options. It combines proven cryptography with practical usability.
How does Firo ensure transaction privacy?
Firo uses zero-knowledge proofs to break the transaction link between sender and receiver. When you anonymize your coins, they enter a privacy pool where they cannot be traced back to you.
Is Firo legal to use?
Yes, Firo is legal in most jurisdictions. Privacy is a fundamental human right. However, users should comply with local regulations regarding cryptocurrency use.
How can I contribute to Firo?
You can contribute by running a masternode, participating in community discussions, developing applications, reporting bugs, or supporting the project through various community initiatives.
