I ran into this inside Sign Network while trying to wire attestations into a compliance flow that looked simple on paper. A verifier issues a credential, a schema defines what counts, and downstream apps read it. Clean. Until you try to make that system hold up under real-world constraints like revocation, jurisdiction rules, and audit trails that actually need to survive scrutiny. The friction shows up in who gets to verify, not how verification works.
At first I assumed governance here was about token voting or parameter tuning somewhere in the background. It is not. It is about deciding which verifier is allowed to write truth into the system, and what happens when that truth later becomes inconvenient. The moment you connect Sign to anything resembling compliance, verifier authorization stops being a technical detail and starts acting like a liability surface.
The system does not break when data is wrong. It breaks when the wrong party is allowed to make it right.
One setup I worked through used a reusable schema for KYC-style attestations across two apps. Same schema, same format, different verifier sets. In theory that should create portability. In practice it created drift. One verifier was issuing attestations with a 24-hour review window, another with effectively instant issuance. Both valid. Both readable. But downstream, one class of users started passing checks faster simply because their verifier had lower latency and looser review thresholds.
Nothing in the protocol flagged this as inconsistent. From the system’s perspective, both attestations satisfied the schema. From a compliance perspective, they were not equivalent at all. Governance here was not a vote. It was embedded in verifier selection, and that selection quietly shaped who moved faster through the system.
Another case was revocation. Sign allows attestations to be updated or revoked, but the responsibility sits with the original issuer. Sounds reasonable until you hit a real scenario. A verifier goes inactive. Not malicious, just gone. Now you have stale attestations that still pass schema checks but no longer reflect reality. To patch this, we had to introduce a secondary verifier layer with override permissions. That reduced one risk but introduced another. You now have a class of actors who can effectively rewrite trust signals after the fact.
The workflow changed immediately. Instead of asking “is this attestation valid,” we started asking “which verifier issued this, and who can override it.” Two extra steps. More cognitive load. Slower decisions.
There is a tradeoff sitting right in the middle of this. Tightening verifier authorization improves reliability but reduces openness. You can require staking, reputation thresholds, or governance approval before someone can issue attestations, and that does filter out noise. But it also slows onboarding and concentrates power. In one internal test, adding a stake requirement cut low-quality attestations by a noticeable margin, but it also reduced new verifier participation enough that schema coverage became patchy. Some regions simply had no active verifiers.
That is where I start to feel slightly biased. I lean toward stricter verifier gating because the failure modes of loose systems are harder to unwind later. But I also know this biases the network toward fewer, more centralized actors. Not ideal for something that wants to stay composable.
If you want to test this yourself, try mapping three verifiers issuing the same schema and see how quickly their behaviors diverge under load. Or take a schema that depends on off-chain data and simulate what happens when one verifier updates their data source and another does not. The protocol will not stop either of them. It will happily carry both forward.
Another small test. Introduce a delay between attestation issuance and acceptance in your app layer. Even a few minutes. Watch how it changes user expectations and verifier behavior. Some will adapt. Others will drop off. That delay becomes a governance tool, even though it lives outside the protocol.
Eventually the token layer shows up, but not where I expected. It does not just coordinate incentives. It defines who can afford to participate as a verifier and who can absorb the cost of being wrong. If staking is involved, then governance is partially priced. Not in a speculative sense, but in terms of who can lock capital to gain authority. That changes the shape of the verifier set before any vote ever happens.
What surprised me most is how little of this is visible at the surface. From the outside, Sign looks like a clean attestation system with flexible schemas and cheap storage patterns. Underneath, governance is happening through small, compounding decisions about verifier admission, revocation authority, and how much inconsistency the system tolerates before someone intervenes.
I am still not sure where the right balance sits. Too open and you get noisy, uneven trust signals that leak into every downstream app. Too strict and you end up recreating the same gatekeeping structures this was supposed to avoid. The protocol does not resolve this for you. It just makes the tradeoffs programmable.
And once those choices are encoded into schemas and verifier sets, they are harder to unwind than they look.
