Is Sign building a verification tool, or a common data language for Web3?
After reading the latest Sign Protocol docs, one line caught my eye: “Sign Protocol is the evidence layer used across sovereign and institutional workloads.”
Not a verification tool. Evidence layer. Big difference
A verification tool solves a specific problem with its own schema, format, and query method. It works in one context but is not composable, portable, or interoperable.
A data language is much bigger. It defines how information is described, structured, and shared across systems. HTTP isn’t a tool to access the web—it’s a language browsers and servers use to communicate. Sign aims to do the same for verification data in Web3.
The foundation is the schema registry. A schema specifies the structure of a claim: required fields, data types, validation rules, and verification logic. Once published, any system can understand exactly what a valid attestation looks like—without storing personal data. Widely adopted schemas create a shared vocabulary.
Attestations apply this language in practice: structured, schema-compliant data that smart contracts can parse and verify on-chain. Sign supports on-chain, off-chain, and hybrid attestations, and SignScan offers REST and GraphQL APIs. This is real infrastructure, not theory.
Schema hooks make the data language programmable. Custom Solidity code can run automatically when an attestation is created, updated, or revoked, turning passive claims into active components driving ecosystem logic.
Sign’s pivot is bigger than I expected. This is sovereign-grade infrastructure for national systems of money, identity, and capital:
TokenTable: allocation and distribution
EthSign: agreement and signature workflows
SignPass: identity verification
These products share the same primitives but operate independently. This is how a true data language works: multiple apps use the same standards instead of building isolated systems.
Sign has raised over $30M from YZi Labs and Sequoia Capital and is partnering with governments in Asia and the Middle East. The OBI program has a $100M $SIGN pool.
Token snapshot: as of 23/3/2026, SIGN trades at ~$0.034, down ~73% from its ATH of $0.1282 in Sept 2025. Circulating supply: 1.64B of 10B (16.4%).
The sovereign infrastructure pivot is double-edged. B2G is bigger than DeFi, but government sales cycles take years. TokenTable revenue is a positive signal, but real deployments need more than announcements.
Adoption is a network effect challenge. Sign competes with Ethereum’s EAS, which already has traction. Protocols need incentives to adopt Sign schemas, while users need enough adoption for attestations to hold value.
I currently hold ~14% of my airdropped SIGN and am considering OBI participation, but I’m waiting for two signals:
Live government deployments with citizen data
Smart contracts in production using schema hooks to automate decisions
Bottom line: Sign is building an evidence layer for the entire ecosystem, not just a verification tool. Its architecture shows a sovereign infrastructure vision, far beyond DeFi. That will determine SIGN’s long-term value.
