We’re entering a new era of digital identity, when your network, reputation, and contributions can unlock real opportunities. But to get there, we need a better foundation: identity systems built on interoperable data.

The idea is simple: just as modern tools make it easy to plug into data, payments, or messaging, digital identity should be composable and portable. Your reputation shouldn't be trapped inside individual platforms, it should travel with you.

Today, most professional and social recognition is siloed. You might have:

• Endorsements on LinkedIn

• Membership in a founder Slack group

• Contributions in GitHub repos

• Event participation from Partiful and Luma

• Mutuals in an expert Discord community

• A large network of trusted contacts that exist outside of any of the above

Each of these signals something about who you are, but they’re scattered, hard to verify, and often invisible outside their original context. If someone wanted to know who trusts you, or what you’re known for, they’d have to piece together a fragmented picture.

That’s where interoperable attestations come in.

An attestation is just a structured statement: you were here, you built this, you know them, they trust you. When these claims are portable and verifiable, they become far more useful, not just for proving who you are, but for unlocking access to new communities, opportunities, or collaborators.

Not all credentials should look the same. Some recognitions are open, where anyone can vouch for anyone. Others are gated, where you can only endorse someone if you meet certain criteria (e.g. you're part of the same program, or you've worked together before).

This flexibility matters. A good attestation system should let people and organizations:

• Define their own rules for issuing or receiving credentials

• Set privacy boundaries, like whether recognitions are visible only to members

• Use custom logic, such as limiting how far endorsements can spread (e.g. only “2 degrees of separation” from a trusted referrer)

• Group or collapse equivalent credentials, so someone with experience at Stripe or Square can be treated similarly in relevant contexts

• Build reputation gradually, with recurring or progressive credentials, not just one-offs

These aren’t just theoretical ideas. We’ve already seen them unlock real behavior. Startup founders use credentials to show who they’ve collaborated with. Engineers use them to track who’s vouched for their skills across projects. Communities use them to create invite-only spaces based on attendance or membership without maintaining spreadsheets or Slack groups manually. These can seamlessly interoperate with other sources of open data like blockchain events and decentralized social.

When identity is built on flexible, interoperable data, it becomes more than just a profile. It becomes proof of participation, trust, and connection. And when that identity can move with you, doors open faster:

• Introductions get warmer

• Cold outreach becomes credible

• Invisible contributions become visible

• Communities can scale without losing trust

We're building toward a world where identity isn’t locked across platforms but can flow with you, whenever and wherever you choose.

Attestation systems are the infrastructure. Interoperability is the unlock.
