State of Privacy

Full-stack privacy for Ethereum: shielded transactions, private reads, and mixnet-routed networking

Your private cloud. Built on top of Züs

The Rust-inspired language that makes it easy to build scalable dApps with the power of validity proofs. Cairo is the first Turing-complete language for creating provable programs for general computation. Cairo lets you write provable programs without requiring a deep understanding of the underlying ZK concepts. From onchain gaming to provable ML, Cairo makes building trustless applications possible. Cairo is also the smart-contract language of Starknet, an L2 blockchain that is verified over Ethereum.

Holochain is a protocol for local first truly distributed applications that have no servers. Holochain applications run on the users' computers. Because Holochain is a protocol there is no built in fee for data exchanges between Holochain nodes. Just like you don’t pay for using SMTP the email protocol. You just use it. Apps built on Holochain are infinitely scaleable. Each app brings its own resources, compute and storage, and then shares a bit of those resources for holographic back up across the network. Every Holochain app runs in a private encrypted network. Nobody except the users of that specific instance of the app even know it exists. Any hacker or government seeing the data stream would not know what it's for. Holochain is perfectly suited for DePIN projects beause it doesn't have the storage and computational overhead of blockchain. While at the same time Holochain apps can work with blockchain projects filling in the gaps where blockchain is lacking.

The first practical Universal Private Settlement (UPS) layer built, with love, for all EVM-compatible chains.

A new private digital currency that leverages the power of Web3 and DeFi without compromising the privacy and security of its users

A high-performance storage network powering limitless applications

Access and Verify user data from anywhere on the internet. Use Cases Our protocol enables various applications, including: - Education Verification - if you want to verify where and what the student is studying. Useful for marketing campaigns and background verifications. - Employment Verification - If you need to make sure the user works where they claim to work. Useful for lending and hiring. - Financial Background - if you need to verify financial background like credit score, accredited investor status etc. Particularly useful in lending and credit. - Shopping History - if you need to give deals and discounts based on users' loyalty to certain brands ... and many more!

Miden is a zero-knowledge rollup built for high-throughput, privacy-preserving applications. Transaction execution and state are pushed to the client side, so users generate ZK proofs locally on their own devices and the network only verifies proofs of correct execution and state updates. Accounts and notes can be public or private, giving applications a hybrid privacy model with programmable, selective disclosure. Miden runs a STARK-based virtual machine and targets onchain finance that needs confidentiality at scale.

ZecHub is the community-driven education hub for the Zcash cryptocurrency (ZEC). Zcash is a digital currency providing censorship resistant, secure & private payments. The Zcash Blockchain utilises highly advanced 'verifiable' zk-snarks that do not require Trusted Setup following the NU5 network upgrade in 2022.
