LF Digital Trust is a Linux Foundation hub that helps people find and connect open-source projects working on interoperable digital-trust infrastructure. Introduced on May 24, 2023, it addresses a practical problem: identity, provenance, confidential computing, wallets, ledgers and industry systems are often developed in separate communities, making duplicated work and integration harder.
What LF Digital Trust means
The Linux Foundation defines digital trust as open standards for technologies that issue, store and exchange digital assets in trusted computing environments, giving participants confidence in how those assets function. In practical terms, the assets can include credentials, identity data, records, content histories and transactions.
The hub is not a single software product or blockchain. It is a discovery and collaboration layer across Linux Foundation projects. Its organizing principle is interoperability: projects can remain technically independent while sharing standards, implementations and governance approaches that let their systems work together.
The Linux Foundation says collaboration on open source and open standards is the fastest path to interoperability. That matters because no one project supplies every part of a trust stack. A provenance standard may need identity credentials; a wallet may need credential formats; a regulated workload may need confidential-computing hardware and attestation.
#1 Best Overall
Which projects are part of the digital-trust ecosystem?
The projects below address different trust problems and therefore should not be treated as interchangeable products.
| Project | Primary trust problem or layer | What it contributes |
|---|---|---|
| C2PA | Content provenance | Standards that document the source and history of digital assets, helping people evaluate whether online media has been altered or misrepresented. |
| Confidential Computing Consortium | Data in use | Hardware-based Trusted Execution Environments and attestation approaches for protecting sensitive or regulated workloads while they are being processed. |
| Decentralized Identity Foundation | Identity and credentials | Open foundational elements, specifications and reference implementations for decentralized identity. |
| LF Decentralized Trust | Ledgers, identity, security and interoperability | A broad Linux Foundation home for decentralized technologies and standards supporting transparency, reliability, security and efficiency in digital economies. |
| Open Metaverse Foundation | Immersive digital environments | Open-source software and standards for scalable, vendor-neutral environments that can interoperate across providers. |
| OpenWallet Foundation | Wallet components | A community for interoperable, open-source wallet components. Its hub specifically states that OWF does not create standards or publish a wallet. |
| AgStack Foundation | Trusted information in food and agriculture | Vendor-neutral identity information for human, machine, animal and geographic assets used in agricultural systems. |
| FINOS | Financial-services and Web3 collaboration | Open-source collaboration aimed at trusted Web3 technologies in finance. |
How the pieces fit together
Provenance establishes where an asset came from
C2PA focuses on a digital asset’s origin and change history. That can make a photo, video or document’s provenance inspectable rather than relying solely on an author’s assertion.
Identity links people, organizations and machines to claims
The Decentralized Identity Foundation works on the specifications and building blocks that let entities control and exchange identity information without depending on one central identity provider. Those building blocks can support credentials used by wallets, applications and industry networks.
Wallets give users a place to manage credentials and assets
OpenWallet Foundation projects target reusable wallet components so applications and vendors can interoperate. The foundation is a component-community effort, not a publisher of one official wallet or a standards body.

Confidential computing protects processing
The Confidential Computing Consortium addresses a different point of exposure: data while it is being used by software. Trusted Execution Environments and attestation can help an organization verify that a sensitive workload is running in an expected protected environment.
Ledgers and governance provide shared records
LF Decentralized Trust brings together technologies for shared records, identity, security, interoperability and scale. Depending on the use case, a ledger can provide a common transaction history, while governance defines who may operate, update or rely on the network.
Industry projects apply the foundations
AgStack applies trusted identity information to agricultural assets and supply-chain contexts. FINOS brings open collaboration to financial-services use cases. The Open Metaverse Foundation applies interoperable standards and software to persistent immersive environments. These projects demonstrate why a common trust infrastructure needs domain-specific implementations.
LF Digital Trust versus LF Decentralized Trust
They are related but not the same.
| Aspect | LF Digital Trust | LF Decentralized Trust |
|---|---|---|
| Role | A cross-project hub and organizing concept for digital-trust work. | A Linux Foundation organization and project home focused on decentralized technologies and related standards. |
| Scope | Includes provenance, confidential computing, identity, wallets, immersive environments and sector projects. | Centers on ledger, identity, security, interoperability, implementation and related decentralized technologies. |
| Introduced or announced | Hub article published May 24, 2023. | Formation announced June 25, 2024. |
| Relationship | Helps readers understand how complementary projects connect. | Provides a more formal home for a major subset of decentralized-trust projects. |
The 2024 LF Decentralized Trust launch announcement described 17 projects and more than 100 founding members. It also reported more than 50 code bases in its labs pipeline and said the Trust over IP (ToIP) Foundation would participate as a pan-industry project providing a common standard and architecture for internet-scale digital trust. Those figures describe the 2024 launch announcement, not a permanent total.
What changed with LF Decentralized Trust?
The Linux Foundation’s June 2024 formation plan positioned LF Decentralized Trust as a neutral home for ledger, identity, security, interoperability, scale and implementation technologies, including Hyperledger projects. The announcement also described directed funding models for strategic project investment.
Rank #4
The launch announcement said professional certifications for individuals and service providers were forthcoming. It did not establish that every certification is currently available, so prospective learners should check the latest Linux Foundation program pages before relying on that pathway.

Choose the technical layer first
- For media and document history, start with C2PA.
- For decentralized identity specifications or reference implementations, examine the Decentralized Identity Foundation.
- For wallet interoperability, look at OpenWallet Foundation components.
- For protected processing and attestation, examine the Confidential Computing Consortium.
- For ledgers and broader decentralized infrastructure, review LF Decentralized Trust and its projects.
- For sector deployments, consider AgStack, FINOS or the Open Metaverse Foundation.
Use the project’s own contribution route
Participation can mean contributing code, reviewing specifications, joining working groups, testing implementations, documenting use cases, sponsoring infrastructure or taking part in governance. Each community sets its own repositories, meeting schedule, contribution rules and membership options; the LF Digital Trust hub’s “get involved” routes are the appropriate starting point.
Separate standards work from production deployment
A specification or reference implementation is not automatically a production-ready service. Before adopting a project, check its current documentation, release activity, security process, license, interoperability tests, operational requirements and support model. The hub brings projects together, but it does not make their maturity identical.
Why interoperability is the central objective
Digital trust fails when a credential cannot be read by a wallet, provenance cannot be verified by an application, or a shared record cannot be reconciled across organizations. Open standards reduce those translation barriers; open-source implementations let participants inspect, test and improve the resulting software.
That does not eliminate governance questions. Participants still need agreement on identifier control, credential issuance, revocation, privacy, key recovery, hardware assumptions, data retention and liability. LF Digital Trust’s value is providing a place to discover communities addressing those questions together rather than treating every project as an isolated technology.
Quick Recap
What LF Digital Trust is—and is not
- It is: a map of Linux Foundation communities working on complementary trust technologies, with interoperability as the connecting objective.
- It is not: one universal identity system, one wallet, one ledger, a guarantee that projects are production-ready, or a claim that all digital-trust challenges have been solved.
