Web3 Privacy Revolution: COTI, Zama, Fhenix, Aleo Lead with 57% Funding Boost

Privacy in the digital world is a growing concern, with users seeking more control over their personal data. The web3 landscape is experiencing a privacy renaissance, transitioning from slow and non-compliant networks to more efficient and legitimate solutions. These advancements are designed to meet the needs of the next wave of blockchain users, offering selective data sharing and opt-in private transactions without compromising transaction speeds or regulatory compliance.

Several companies are at the forefront of this privacy revolution, each bringing unique technologies to the table. COTI, for instance, has launched its v2 mainnet, an EVM-compatible and privacy-focused Layer 2 chain. This technology, powered by Garbled Circuits, allows smart contracts to process encrypted data without revealing its contents. This capability is already being utilized by COTI perps exchange PriveX to protect trader behavior and strategy from exploitation. COTI's deep enterprise connections enable businesses to keep company data secret while maintaining full compliance, making it a frontrunner for everyday web3 adoption.

Zama is another key player in the privacy space, focusing on Fully Homomorphic Encryption (FHE). This technology allows encrypted data to be computed without decrypting it, making it ideal for sensitive operations like running analytics on private health records or placing financial trades on a public ledger. With a recent $57 million Series B funding round, Zama has achieved unicorn status and is poised to make FHE a working reality. Its confidential blockchain protocol is already live on a public testnet, with the mainnet scheduled for late 2025. This approach ensures a privacy-friendly environment capable of supercharging institutional inflows.

Fhenix is another advocate of FHE, having built a dedicated blockchain powered by this privacy technology. Fhenix's confidential infrastructure ensures data stays encrypted from start to finish, enabling private smart contracts, secure AI training, and fair gaming. Their CoFHE tool simplifies the integration of privacy into any EVM-compatible dapp, with heavy lifting handled by an off-chain FHE Coprocessor for speed and scalability. Fhenix's mainnet went live in January, following a $15 million raise and a strategic partnership with Offchain Labs to integrate with Arbitrum. Their technology addresses web3’s Achilles’ heel: public data that scares off enterprises, proving FHE can be developer-friendly without needing a cryptography PhD.

Aleo is building zero-knowledge solutions from the ground up, showing that this versatile technology can deliver onchain privacy without losing scalability. As a Layer 1 network, Aleo uses ZK proofs to let users run computations privately while verifying results publicly. Their Leo language simplifies ZK development, and tools like snarkOS and snarkVM make it scalable for everything from private payments to decentralized identity. Aleo's partnership with Google Cloud in February boosted its validator network and integrated its data into Google's web3 portal, signaling institutional-grade readiness. Founder Howard Wu emphasizes “decentralized private computation” (DPC) as the most scalable way to shield user data without compromising speed.

As these companies continue to innovate, opt-in privacy is on course to become universally available across every network, dapp, and wallet. This rollout will enhance the onchain landscape, enabling web3 users to interact with the assets and services they love while keeping their sensitive data under wraps. The future of web3 privacy looks promising, with these companies leading the charge towards a more secure and private digital world.
