History has shown that the greatest discoveries and innovations can be used for purposes not intended by their creators. By extension, this statement also covers the rapidly evolving field of technology, where each year seems to come with its own crop of pioneers ready to challenge the status quo with their innovative solutions and approaches. Despite the groundbreaking potentials of artificial intelligence (AI), there are possibilities that bad actors can utilize it for malicious purposes.

That’s where Proof of Human (PoH) comes in, a consensus mechanism developed by Humans.ai to usher in a new era of trust in AI and blockchain. Although the intersection of blockchain with AI seems like a natural occurrence, Humans.ai is the first company to successfully deliver a clear use case that leverages the unique properties of both technologies.

At the center of the Humans.ai ecosystem is the PoH mechanism, a complex blockchain-based system that ensures that every AI NFT is backed by a human decision. Through PoH, humans leverage their biometric data to prove that a specific AI is still under close biological supervision. Humans.ai empowers people to participate in the governance and management of any AI, essentially making sure that the objective of the AI is aligned with the best ethical practices and human objectives.

Simply put, PoH is a complex and versatile mechanism that ensures three key functions related to AI NFTs, namely governance, consensus, and verification. To ensure the governance of an AI NFT, Humans.ai utilizes PoH to confirm that behind every request made towards an AI model, there have been multiple digital signatures of real people. These digital signatures are generated through a mix of different data such as private keys and biometric data — fingerprints, heartbeats, retina scans, face recognition, etc.

PoH ensures that requests made towards the AI NFT align with the governance rules outlined inside the NFT by its owner. For instance, Alex has integrated her voice inside an AI NFT. To protect how her voice is used by third parties, Alex can inscribe a set of rules inside her AI NFT that outline how her biometric data should be utilized. To illustrate, Alex can stipulate that her AI NFT must not be used to produce obscene content, hate speech, or anything politically incorrect. PoH ensures that Alex’s wishes are always respected.

In conclusion, just like other consensus mechanisms, PoH is designed to solve inherent flaws in distributed systems where actors do not know or trust each other. PoH takes this even further by ensuring that the massive power of AI is channeled to the greater good. By ensuring compliance through governance, consensus, and verification, PoH is truly redefining the use of AI for ethical good.
