Manta Network is excited to announce its work with Cradles to launch the zkFrontier for both Cradles and Manta community members. Cradles zkFrontier offers users a decentralized, trustless, and private way to verify their real identities without compromising information or data leakage about their on-chain activity.

Through this partnership, Manta Network will provide the Cradles community members with the ability to mint a Zero-Knowledge Decentralized Identifier (zkDID) in the form of the zkFrontier, a private soul-bound token (zkSBT) that allow users to privately verify their on-chain activities related to Cradles without compromising any information or data leakage about their on-chain activity. By minting a Cradles zkFrontier, users gain the ability to utilize it within projects within the Manta ecosystem, all while maintaining privacy without disclosing their address. Leveraging Manta’s zk innovation-proof key, the integration of Manta’s zkSBT extends to both Web2 and Web3 mobile applications, seamlessly linking with various chains and ecosystems.

Eligibility & Minting a zkFrontier

To mint a zkFrontier, community members must have minted an OAT in the Cradles x Galxe WLs Campaign or hold a Manta Giant Squid NFT.

Cradles’ OAT holders and Giant Squid NFT holders are eligible to mint the zkFrontier as a privacy-enhanced on-chain representation of their accomplishment. To mint your zkFrontier, head over to the Manta Network NPO page. Users can mint the zkFrontier from June 9th at 9AM EST to June 18th at 9AM EST. For a step-by-step guide, follow our tutorial here.

How to Join the Cradles Public Beta

Manta Network will whitelist 1,000 zkFrontier holders to participate in the much-anticipated Cradles public beta, launching on June 25th. To be eligible for this opportunity, users must have successfully minted the zkFrontier. As a token of appreciation, Manta Network will airdrop an NFT to 1,000 randomly selected zkFrontier holders, granting them access to the public beta upon its release. Whitelist winners will be announced on June 20th.

The Existing On-Chain Identity Problem

The current state of public blockchains presents challenges where every on-chain action is recorded, immutable, and completely transparent. While this transparency was initially essential for trustless verification, it has led to issues such as surveillance, unauthorized data access, and a compromise in user safety and security during on-chain interactions. Manta Network’s implementation of zero-knowledge proofs offers a solution by enabling trustless verifiability without the need for complete on-chain transparency. As a result, users can enjoy a seamless, modular privacy experience.

Manta Network’s research into zero-knowledge proof circuits has been integrated into its flagship platform, the NPO, which allows users to mint zkSBTs. These on-chain, verifiable credentials provide a trustless layer of privacy. By combining them with proof keys, users can verify their ownership of zkSBTs without even connecting a wallet, ensuring a seamless and modular privacy experience when engaging with applications.
