From the anonymous authors of The Federalist Papers laying the foundation for democratic debate to whistleblowers like WikiLeaks exposing global injustices, the practice of pseudonymity allows individuals to freely share thoughts and truths without fear of retaliation. Historically, figures such as Voltaire, Publius, Mark Twain (real name Samuel Clemens), George Eliot (real name Mary Ann Evans), and Satoshi Nakamoto have all advanced the dissemination of ideas through pseudonyms.

Zero Knowledge (ZK) Proofs

Zero Knowledge Proofs are a revolutionary cryptographic technology that allows one party to prove to another that they possess certain information without disclosing the specific details. For example, you can prove that you meet the age requirement to enter a venue without showing your full personal information on your ID. This technology ensures the confirmation of key facts (like age) while protecting other private data.

In traditional platforms, users typically need to submit personal data, which is stored centrally on servers, posing risks of leakage or misuse. Zero Knowledge Proofs change this model, allowing users to verify credentials or ownership of assets without exposing personal information, significantly enhancing privacy protection.

Genesis

Sealcaster is the first Zero Knowledge application built on the Farcaster protocol, developed by Big Whale Labs. The development team includes Nikita Kolmogorov (borodutch), Jason Kim, and other members. They utilize Circom, a programming language specifically designed for Zero Knowledge circuits, to generate proofs that enable users to complete identity verification without disclosing personal information. Through Circom's constraints and signaling mechanisms, Sealcaster can verify the authenticity of credentials while protecting user privacy.

Sealcaster is one of several Zero Knowledge products launched by Big Whale Labs, with other products including:

• SealCred: A platform that allows users to mint zk-NFTs based on NFT and email ownership.
• SealCred Echo: A tool that enables users to anonymously post content on Twitter along with verification credentials.
• Ketl: A tool for pseudonymous communication for venture capitalists and entrepreneurs.

As one of the first practical Zero Knowledge projects on the Farcaster protocol, Sealcaster demonstrates the immense potential of privacy protection and verifiable communication on decentralized platforms.

Superanon

As the Farcaster community continues to grow, a premium user client called supercast (developed by its founder woj, later renamed super) has gradually formed a user base, leading to the birth of superanon.

supercast is a currently paid client aimed at advanced users. It supports posting content from multiple accounts and allows users to operate anonymously using superanon.

ANON

In the Farcaster community, the AI-driven token launcher CLANKER has facilitated the creation of over 10,000 tokens, with a total trading volume of $1 billion, paying creators millions of dollars. One day, a superanon user anonymously created a token named $ANON using CLANKER while woj was asleep, embodying the characteristics of permissionless operation.

When woj woke up, he officially launched the $anon token (in lowercase) as a support tool for superanon accounts and distributed donated $ANON to all supercast users through an airdrop.

Subsequently, developer slokh (who previously developed the nook client) built a platform called anoncast.org, allowing users to anonymously post content while holding $ANON.

This platform combines Noir and Rust technologies, and its open-source code has attracted many developers for iteration and experimentation, opening new possibilities for anonymous social networks.

In addition to continuous feature updates and optimizations, such as allowing users to reveal themselves as the authors of popular content at a later time, Farcaster's features have attracted many well-known users, including Vitalik and Jesse Pollack. Notably, 0xLuo is the creator of the feature on the right.

33Bits

33bits.xyz is an experimental platform with access limited to users with FID numbers below 20,000, specifically early users of Farcaster. The tool was built by developers Kugusha and Sergey. To expand access, they later launched 66bits.xyz, which not only provided access to more users but also added extra features for token holders.

Rumours

Developed by Disky and Leovido, rumourcast.xyz is a client based on the Farcaster protocol. It builds on the popular Anon Cast but incorporates some unique innovative designs.

As long as users hold enough supporting tokens, they can post content as anonymous accounts. Future development plans include:

Frames V2 integration: Enhancing user interaction experience by creating unique frame features.

NFT minting: Supporting the minting of rumor content into collectible NFTs, potentially combined with prediction market features to add more interactivity and value to the content.

RumourAI agents: Using AI technology to expand and optimize rumor content, adding more depth and creativity to each post.

These feature iterations are ongoing, and the future looks promising.

Pseudonymous Economy

A complete shift towards a fully financialized pseudonymous framework may overlook the complexities of human social interactions. However, the true potential lies not in absolute anonymity, but in constructing diverse and complex identity models.

These online and on-chain social experiments provide users with a unique space. Here, individuals can build reputations, share insights, and collaborate without exposing their true identities, thereby alleviating the pressure of personal information exposure.

While a completely anonymous model may struggle to support complex social or governance structures, these verified digital identity models offer new possibilities. These identities can be trusted and used across platforms while protecting personal privacy. They pave the way for an online social environment characterized by voluntary participation and flexible identity movement, redefining the power dynamics of online communication.

Through these tools, we can better find a delicate balance between transparency and privacy protection, collective trust and individual freedom.
