The Signal
When the internet was first built in the 1970s, it was designed simply to connect computers together. The question of identifying who was actually on the other end of a connection was never part of the plan. That missing piece set off a chain reaction that still defines how we live online today. Everything we now use to prove who we are, from passwords to “with Google” to blockchain IDs, which are genuinely impressive in their own right, has been built to patch that original gap. We have been retrofitting a structural problem ever since.
Digital identity is now required for nearly everything online: logging into apps, proving asset ownership, and accessing financial services. The systems in place have improved considerably. They still carry the same structural limitations from the original design oversight.
This is why a free course the Cardano Foundation recently released through the Cardano Academy caught my attention. It covers a protocol called KERI, and not just because of what it teaches. KERI approaches the identity problem differently from every existing solution.
Why KERI and the New Course Matter
Three major workarounds define how digital identity works today, and each one requires handing trust over to a third party.
1. The Big Tech Problem: Federated Identity
“with Google” is convenient. It is also a single point of failure. If a corporation suspends your account, or a platform goes offline, you lose access to every service ever connected to that login.
2. The Hacker Problem: Administrative Trust
For general web security, we rely on organizations called Certificate Authorities to verify who is legitimate online. Certificate Authorities are high value targets. If one is breached, an attacker can issue fraudulent certificates that trick the internet into trusting fake versions of any domain.
3. The Blockchain Problem: Algorithmic Trust
Blockchain removes the central corporation but brings its own complications. Rotating a security key means paying transaction fees. Permanent ledgers conflict with privacy laws like GDPR. Depending on a specific network creates a new form of vendor lock-in, trading one dependency for another.
KERI removes the middleman entirely. Whether that middleman is a corporation, a certificate authority, or a public blockchain, KERI cuts it out. You certify yourself. You become the authority over your own digital identity.
Already Working in the Real World
KERI is not theoretical. It is already in production through the verifiable Legal Entity Identifier system, vLEI. Organizations managing millions of corporate identities are using it. The European Banking Authority has piloted it for banking regulation.
The Cardano Academy course is free, takes about an hour, and requires no cryptography background.
If you want to understand where digital identity is headed, it is a good use of an afternoon.
