Feature parity — and where we go further
Use NobleID alongside DOIs. You get everything you expect—global identifiers, resolvers, machine-readable metadata, OAI-PMH—and a set of verifiability and identity features that make research easier to trust.
| Capability | NobleID | Typical DOI ecosystem (Crossref/DataCite) |
|---|---|---|
| Free to mint | Yes — free to mint for individuals and organizations. Optional publisher tiers add quotas, tooling, and SLAs. | Often fee-based (membership and/or per-deposit), depending on registry and plan. |
| Blockchain-backed mirror | Yes — decentralized mirror and nightly fixity checks; optional public blockchain anchoring post-GA. No wallets or blockchain steps for users. | Not standard; typically centralized hosting with institutional redundancy. |
| Versioning model | Stable root + explicit v1…vN; resolver defaults to latest; all versions stay citable. | Versioning varies by publisher; not uniformly visible at the identifier layer. |
| Update badge | Tiny "Check for updates" widget (≤12 KB, SRI/CSP-ready) to keep readers on the latest. | Not standard at the registry layer. |
| Identity & attestations | NobleID-P (privacy-preserving). Authors claim works; co-authors and institutions attest (ROR). ORCID linking optional. | ORCID linking common; formal co-author/institution attestations not handled at registry layer. |
| Tamper-evident receipts | Signed receipts (content digests + storage pointers) on every version; verify in seconds. | Not standard at registry layer. |
| Machine-readable metadata | JSON-LD, CSL-JSON, BibTeX, RIS on each resolver. | Yes — strong support across registries/publishers. |
| Discovery & harvesters | Sitemaps + OAI-PMH; canonical + sameAs to reduce duplication. | Yes — sitemaps and OAI-PMH widely used. |
| Grants & outcomes | Grant NobleIDs (funders mint once); outputs aggregate on the grant resolver; CSV/JSON exports. | Funders register grant DOIs via dedicated programs; linkage appears when publishers include grant metadata. |
| Work type coverage | Broader coverage by default: books & chapters, proceedings & conference papers, dissertations, reports, standards, peer reviews, and components—first-class with versioning and relationships. | Primarily articles and datasets; other types supported but with varying metadata richness across registries. |
| Disputes & transparency | Visible resolver banners (Disputed/Withdrawn); audit lines persist. | Not standard at registry layer; handled by publishers/policies. |
| Exports & snapshots | Nightly snapshots or on-demand bundles (works, versions, receipts, Signals, grants). | Registry APIs available; bulk export varies by provider. |
| Governance & openness | NobleBlocks-led, open roadmap and policy registry; standards-first. | Non-profit registries with member governance. |
Notes: DOI program features and costs vary by registry and membership plan. Publishers may implement additional features independent of registries.
Individuals and organizations mint NobleIDs at no cost. Publisher plans add higher quotas, batch tooling, and SLAs when needed.
We maintain a decentralized mirror and run nightly fixity checks. Optional public blockchain anchoring (post-GA) adds a public timestamp—no wallets or tokens required.
NobleID plays nicely with DOIs. We include sameAs pointers in JSON-LD to avoid duplication and improve discovery.
