Proof-of-Identity
Ayrıca şöyle anılır PoI, identity-anchored validator eligibility
Origin:
composes. The phrase was in public use roughly a decade before this project, in seventy-seven repositories, the oldest from 2016. Solidus narrows an existing idea to validator admission. Solidus status:roadmap, designed and named, not yet enforced by the running code.
Proof-of-Identity (PoI) is a proposed rule for deciding who is allowed to become a validator on a blockchain: not just "whoever posts enough stake," but "whoever posts enough stake and can prove they are a distinct, verified human being." Ordinary stake-based validator sets (see Validator) resist Sybil attacks, one entity pretending to be many, purely through capital: running ten validators costs roughly ten times the stake of running one. That works, but it means a sufficiently well-capitalized actor can still accumulate outsized influence. Proof-of-Identity adds a second, independent cost: each validator slot must also be backed by a unique, verified human identity, so accumulating influence requires acquiring both capital and distinct verified identities, a qualitatively different, harder problem.
It is important to say clearly what this is not: it is not a new way of reaching Byzantine agreement. The actual block-by-block consensus mechanics are ordinary HotStuff BFT, leader election, voting, quorum certificates, all of it. Proof-of-Identity is a gate on the guest list for that consensus, not a replacement for the consensus itself. An earlier internal design used "Proof of Identity" as if it named the whole consensus algorithm; Solidus's own architecture documentation now explicitly corrects that framing.
Why this is the one invented term here
Nearly every other entry in this Lexicon exists to make a point: Solidus composes roughly forty-plus open standards and cryptographic primitives that other people built, and says so plainly. Proof-of-Identity is the deliberate exception: the one place Solidus is not borrowing. That makes it the highest-scrutiny term in the entire Lexicon, and the one most tempting to oversell. So: it is not oversold here.
The honest state of it today
Solidus's own architecture documentation says it directly: the KYC-Level-2 credential requirement, an 800-point reputation floor, and a 95% uptime requirement for validator admission are "part of the roadmap validator-admission model, not enforced on the current testnet." Today, the live validator set is admitted on a stake minimum alone: the identity-verification half of "Proof of Identity" is specified but not yet checked by any running code. There is a real difference between "we designed a rule that binds validator eligibility to verified personhood" (true) and "our network currently enforces that rule" (not yet true), and this entry exists to keep that difference visible rather than let the name do the talking.
Worth naming honestly, too: Solidus is not the first project to try binding personhood to a network mechanism. Proof of Humanity uses video submission and social vouching to build a registry of unique humans for a universal-basic-income-style token distribution. Worldcoin uses iris biometrics to issue a unique proof-of-personhood credential, primarily for Sybil-resistant airdrops and access. Solidus's proposed use is narrower than either: it targets validator eligibility specifically, using the KYC credential its own Verify product would issue, rather than a new biometric enrollment step.
Check it yourself
You can't, yet, and that's the point of saying so rather than hiding it. No external party has been through a KYC-gated validator-admission flow on Solidus; the requirement exists in the protocol specification and the validator guide, not in enforced, running code. When that changes, this entry should change with it.

Nereden geliyor
Bunu başkası belirtti. Solidus bir araya getiriyor.
Solidus did not coin this term and does not claim to. A public code search for the hyphenated phrase returns seventy-seven repositories in this same field, the oldest visible one dating to 2016, so the phrase was in circulation roughly a decade before this project existed. That establishes prior public use; it does not establish who coined it, and we are not awarding that to anybody including ourselves. Binding a verified person to network participation is likewise prior art: Proof of Humanity, BrightID, Idena and Worldcoin each attempt it. What Solidus proposes is narrower, that validator admission require a verified-human credential as well as a stake bond, so one operator cannot cheaply run many validators by splitting capital across addresses. That is a scoping decision inside a known design space, not a new mechanism. This entry previously carried `origin: invented` and called itself Solidus's one original contribution. The claim is withdrawn, and the estate had already retracted it in the explorer article on this term while this entry still asserted it.

None yet. No external, independently-onboarded validator has gone through a KYC-gated admission flow: the requirement is written into the protocol specification and the validator guide, but has not been exercised end-to-end outside the founding team's own nodes. There is no command a stranger can run to verify this property holds today, because it does not yet hold.
