Recently, I’ve been quite curious about a concept that’s been popular in the blockchain community — Proof of Humanity, or PoH for short. So, what exactly is PoH? Simply put, it’s a way to verify that you are a real person through blockchain, not a bot or some automated system.

Unlike traditional Proof of Work or Proof of Stake, PoH focuses on proving the “humanity” of users. Its operation is quite interesting — users must submit their profiles and undergo a verification process carried out by the community. Other users will check whether the person in the profile is a real human, usually through videos, photos, or other identity verification methods.

I think the best part of Proof of Humanity is that it addresses issues of bots and network manipulation. Once verified, users gain access to mining rewards or governance rights. Some projects even distribute UBI tokens (Universal Basic Income) to verified individuals, essentially providing periodic cryptocurrency payments just to prove you are human.

There are a few notable projects applying PoH. The Proof of Humanity project on Ethereum is the most famous implementation, building a registry of verified people and distributing UBI tokens to them. After verification, you start receiving regular UBI tokens that you can hold or trade.

BrightID is another protocol focused on proving that each user is unique, helping to prevent sybil attacks. Idena also operates similarly, with its own blockchain where users are rewarded for verifying their human identity through challenges. Worldcoin has bigger ambitions — using biometric identification to ensure each participant is a real person, with the goal of distributing global cryptocurrency.

Looking into the future, Proof of Humanity has significant potential. As decentralized identity solutions develop strongly, we might see PoH being more widely adopted in DeFi, governance, and identity management. In the long run, it could contribute to greater financial inclusion, allowing more people to access UBI systems or other digital reward mechanisms.

If you’re considering participating in PoH-related projects, be cautious. Since many projects are still developing, it might be wise to start with small positions or use dollar-cost averaging strategies to diversify risk. The success of PoH heavily depends on user acceptance, which could take time. But as decentralized identity becomes more important, these projects could become increasingly valuable.

I’m curious to hear what you all think about Proof of Humanity. Has anyone tried participating in these projects yet?
