LinkedIn is a self-attested reputation system. You write your own resume. You list your own skills. You describe your own experience. Anyone can claim anything. The “endorsements” feature — where connections click a button to confirm your skills — adds social signal but not verification. Nobody checks whether the endorser actually worked with you, or whether they have the standing to evaluate the skill they are endorsing.
Strip LinkedIn’s trust model to its operational content and it is: “this person claims these things about themselves, and some other people clicked a button.” The correspondence between the profile and reality is unverified. The system works because humans apply their own judgment on top of it — checking references, conducting interviews, reading between the lines. The profile is a starting point, not evidence.
Agents cannot read between the lines. When an agent is tasked with finding a contractor, evaluating a hire, or assembling a team, it needs verifiable claims, not self-attestations. The LinkedIn model does not survive agent mediation.
What replaces it.
The EU is building the substrate with EUDI wallets and the eIDAS 2.0 framework. By 2027, every EU citizen will have access to a digital identity wallet that can hold verifiable credentials — signed attestations from third parties about the holder’s attributes. A university signs a credential attesting to a degree. An employer signs a credential attesting to employment dates and role. A professional body signs a credential attesting to certification.
These are not self-attestations. They are third-party verified claims, cryptographically signed, revocable, and machine-checkable. An agent evaluating a contractor can verify the credential chain without calling references, checking websites, or relying on social proof. The verification is automatic, instant, and cryptographically sound.
Combine EUDI wallets with A2A Agent Cards and you get something that looks like the professional profile of 2032: a verifiable credential portfolio, machine-readable, agent-queryable, and structurally incapable of the kind of inflation that makes LinkedIn profiles unreliable.
The transition.
The transition from self-attested to verified professional identity will not happen all at once. It will happen credential by credential, as institutions begin issuing verifiable credentials alongside their traditional paper certificates.
Universities are already piloting this. The European Blockchain Services Infrastructure (EBSI) has a credential framework. Several professional bodies are exploring digital certification. The bottleneck is not technology — it is institutional adoption. Each institution that begins issuing verifiable credentials adds to the network’s value. The network is currently small. But it is growing, and the EUDI wallet mandate will accelerate it.
The design challenge is the transition period: when some credentials are verifiable and others are self-attested, how does an agent weigh the mix? A contractor with three verified credentials and two self-attested claims is more credible than one with five self-attested claims. But how much more? The weighting model does not exist yet.
What does seem clear is the direction. Self-attestation is a stopgap from an era when verification was expensive. Verification is becoming cheap. The profiles that survive agent mediation will be the ones with the deepest attestation chains. The ones that do not will look like the used car without the CarFax: maybe fine, but why take the risk when verified alternatives exist?
