Twin3 proposes proof of authenticity (PoA) to achieve computable humanity.

The protocol introduces a 256-dimensional vector identity model (Twin Matrix), transforming abstract human traits into verifiable on-chain assets, establishing a trust foundation for human-machine collaboration in the AI era.

In the current decentralized identity (DID) space, the vast majority of efforts are focused on solving a fundamental question: “Are you a human, and are you a unique individual?” From biometrics to social graph verification, the industry is building the foundational “Proof-of-Personhood (Proof-of-Personhood)” layer for the Web3 world. However, twin3's “Proof-of-Authenticity, PoA(” protocol is guiding us to think about a deeper question: after proving “who you are,” how do we prove “what kind of person you are”? The protocol aims to go beyond the existing DID 1D framework and provide a richer and more meaningful identity infrastructure for the upcoming AI-deeply involved “Agentic Economy )Agentic Economy(.”

The evolution of PoP, PoR to PoA in digital identity: From “existence” to “essence”: The dimensional upgrade of DID

Traditional 1D identity proof, whose core goal is to prevent Sybil attacks, ensures that one address corresponds to one real individual. This is crucial in scenarios such as DAO governance and airdrops, but it does not contain any information about individual traits. “It addresses the 'uniqueness' of identity, but overlooks the 'substance' of identity,” said Ming Wen, founder of twin3. “In an era where AI is about to become our digital extension, an identity lacking substance is insufficient. What an AI Agent needs is not only to know that it represents a real person, but also to deeply understand this person's tastes, skills, values, and preferences.”

To this end, twin3 introduces a revolutionary concept – “Computable Human )Computable Human(”. At its technological core is a proprietary protocol called Twin Matrix. This protocol engineers the intrinsic characteristics of each unique individual across four fundamental dimensions: physical, digital, social, and spiritual, into a 256-dimensional encrypted vector. This vector, known as “digital human DNA”, will ultimately be minted into a soulbound token fully owned by the user, )Soulbound Token, SBT(. It is no longer just an identity credential, but a verifiable, computable, AI-readable “digital body”, becoming a unique and contextually rich identity expression for users in the Web3 world.

“What we are doing is creating a vector space for 'human nature' itself,” Ming Wen explained. "This makes abstract human traits computable for the first time. This 256-dimensional Twin Matrix vector is not randomly set, but is based on a philosophical framework that encompasses the four fundamental aspects of human existence, with each dimension composed of 64 sub-vectors, ensuring the comprehensiveness and depth of the captured data.

Physical dimension: Capturing human sensory preferences (such as taste, smell), biological rhythms, and environmental interaction patterns as a physical existence. This forms the basis of all “experiences” and is the area that AI finds most challenging to simulate.

Digital Dimension: Integrating verifiable footprints of users in the digital world, such as GitHub contribution records connected through APIs (representing programming capabilities), on-chain transaction behaviors (representing risk preferences), as well as verifiable credentials like educational certificates.

Social Dimension: Capturing human cultural identity, language ability, roles, and influence within specific communities (such as Farcaster or Discord) as social animals.

Spiritual Dimension: Exploring the deepest inner world of humanity, including quantifying users' core values (such as the degree of emphasis on fairness and privacy) and decision-making tendencies in classic ethical dilemmas through a series of psychology-validated situational tests.

The SBT minted by Twin Matrix will become the user's “digital avatar” in the entire digital world. It not only proves “who you are”, but also in a credible and computable way, demonstrates “what kind of person you are”. This provides a reliable identity foundation for human-machine interaction and value exchange in the AI era.
