We’re excited to announce the Kairos Protocol™— a new way to leverage the benefits of Kairos Face Biometrics, and the new standard in Identity Verification for dApps. (Links to code at the end of this article).


With just a few lines of code, developers can integrate state-of-the-art facial recognition with their dApps. Ensuring that face recognition technology remains inclusive, accessible, and accountable is our our priority and our mission. We’ve developed this protocol to improve our industry by making natural identity usable and safe— for everyone. This alpha release will expand greatly in the coming months. Our goal is to root Kairos Protocol™ as an identity standard to benefit the entire industry.

The Kairos Protocol™ consists of the following:

  • Open-sourced Human Identity Interface™
  • Kairos Face Recognition API endpoints

"Today more than ever people want access to trusted experiences, especially when it comes to making high-value transactions," said Brian Brackeen, CEO of Kairos. "And that access shouldn’t be exclusive to only the wealthy or priviledged. By democratizing our face recognition technology through the Kairos Protocol™, we hope to provide inclusive, frictionless identity options for all types of blockchain businesses. With the proliferation of decentralized services, it felt like the perfect community to launch into— the growth and passion of this industry is evidence that we can play a key role in accelerating the disruption of decades-old identity technology and corporate inertia."

Why we built the Kairos Protocol™

We built Kairos Protocol™ because legit digital transactions require legit digital identity solutions. Blockchain technology has enabled its users to securely and efficiently store value, without it being tied to a physical identity— which represents ownership without divulging the owner’s true identity. This is a powerful characteristic of blockchains that facilitates efficient and private economic activity. And who doesn’t want that?!

But here’s the catch… the pseudo-anonymous nature of these systems could be exploited by malicious users

The only requirement for a user to participate in a blockchain system is to obtain a public/private keypair— there is no other form of identity required. Malicious activity perpetrated within these systems can be extremely costly to track and respond to in the form of legal or other external actions. A malicious user could be a:

  • Hacker
  • Fraudulent market participant
  • Participant in a transaction for illicit goods or services

Kairos’ industry-leading face recognition software is optimizing, and democratizing, digital identity management on the blockchain— creating physical identification level confidence in digital identification processes. Basically, we’re proposing to introduce real world accountability to the decentralized, digital economy.

Kairos Protocol™. It’s an actual thing.

At Kairos, we like to go to market with products rather than ideas. So we built a demo that leverages the Kairos Protocol™. The result is a digital wallet initially conceived to manage our own digital token called the Kairos ID Token™.

Try the alpha release:

Let’s get technical...

The ID Wallet™ is a client-side wallet dApp that implements the Kairos Protocol™ (HII™ + Kairos Face Recognition API). Users have the ability to store, send, and receive ID Tokens™, as well as issue payment requests to other ID Wallet™ users.

Why is the Human Identity Interface™ important?

Because the HII™ is a smart contract interface that defines the standard by which Kairos, and other biometric identity verification providers, interact with contracts that implement it. The HII™ is an interface (similar to ERC20) that, when implemented by a smart contract, provides identity-providers (like Kairos) the ability to interact with that smart contract programmatically and autonomously. The initial implementation of this standard interface targets the Ethereum blockchain, but could be applied in other decentralized systems in the future.


Until existing wallets have the ability to cater to ID Token™ use cases, HII™ will lead as the primary client interface used for holding and transacting ID Token™. And… Because the ID Wallet™ is available for third-party integrations via an open source SDK, adoption by mobile and traditional web applications is entirely feasible.

Projects that would benefit from a biometrically verified token payment system, but don’t necessarily have the resources to create their own, are now able to get in the game by using system.

Use cases that inspire us

While we are defining standard methods for physical identity verification, we’re also working with partners on standardized, industry-specific implementations of the Kairos Protocol™.

For instance:

  • A philanthropic decentralized application (dApp) that uses the Kairos Protocol™ for KYC/AML compliance.
  • A voting platform that uses the Kairos Protocol™ to confirm each participant follows voting rules.
  • A supply chain dApp that requires “human oracles” (humans who enter data into a blockchain) to use Kairos Protocol™ in order to disincentivize fraudulent data entry and other malicious behavior.

A compelling future for Identity

If you’re reading this in consideration of using Kairos Protocol™, you know that you are at the starting gate to the biggest race in modern history— decentralized technologies.

We appreciate the shared vision of early adopters, so we’re giving hands on walkthroughs of the Kairos Protocol™ and can help you integrate with your dApp— This email address is being protected from spambots. You need JavaScript enabled to view it..
