On April 21, 2026, Linux Foundation Decentralized Trust (LF Decentralized Trust) announced eight new general members and two associate members. The same announcement said the Open Tokenized Asset Standard (OTAS) had joined LF Decentralized Trust as a lab—an open development effort for smart-contract reference implementations, not a finished or universally adopted standard.
Who joined LF Decentralized Trust?
The April 21 announcement grouped the ten organizations by membership category:

| Category | New members |
|---|---|
| General members | Affinidi, Espresso Systems, FairSquareLab, First Person Cooperative, Hashlock, Horizen, Innovation Labs by Identity Digital, and Matter Labs |
| Associate members | Advanced AI Society and ERC-3643 Association |
The release identifies the categories but does not detail their respective membership rights, so the labels should not be treated as evidence that the two categories have identical participation terms. LF Decentralized Trust’s announcement also included statements from organization leaders about the ecosystem’s scope and the growing importance of trust in decentralized systems; those are attributed perspectives, not independent evidence of adoption or performance.

OTAS is described as an effort to develop open-source smart-contract reference implementations for tokenized financial instruments. OpenAssets proposed the project, with Sui Foundation/Mysten Labs named as an initial sponsor. Its stated aim is to provide a neutral, auditable onchain foundation that institutions can build on or integrate with production platforms.
Becoming an LF Decentralized Trust lab places OTAS within an open development organization. It is a project and standards-development milestone, not proof that a final specification has been approved, that institutions have deployed it, or that the market has adopted it broadly. The April announcement does not establish independent validation, comparative performance, or adoption figures for OTAS.
What LF Decentralized Trust does
LF Decentralized Trust hosts open development across blockchain, ledger, identity, cryptographic, and related technologies. When the Linux Foundation announced its intent to form the organization in 2024, it described an umbrella for Hyperledger projects and additional open-source software, communities, standards, and specifications for decentralized systems of distributed trust. The formation announcement provides that organizational context.
Practical signals for enterprise readers
Besu deployment support
The April release says FairSquareLab was already a Besu Certified Service Provider (CSP), and ioBuilders had completed the requirements to become one. LF Decentralized Trust describes CSPs as designated companies with proven proficiency and vetted capabilities to help enterprises adopt and deploy its projects. This is the announcement’s clearest practical lead for organizations seeking Besu implementation support; it does not establish referral terms or guarantee a particular provider’s suitability for a project.

A Fabric case study in Brazil
The release points to Ligue 180, Brazil’s National Violence Against Women Hotline, as a Hyperledger Fabric case study. It says Fabric provides tamper-resistant complaint records while protecting victims’ privacy and enabling auditability for authorities. The system is operated by a BrBPO–Metasix Tecnologia consortium for Brazil’s Ministry of Women. LF Decentralized Trust’s announcement says more than 2,000 women turn to the hotline each day; that figure is attributed to the announcement, not independently verified here.

How the announcement fits the later timeline
LF Decentralized Trust’s membership and project landscape continued to change after April. In a September 24, 2026 update, the organization announced 15 further members, including Swift, Wells Fargo, Sui Foundation, and Interchain Foundation. That update also described Panurus as a token-infrastructure project, CLPR as a cross-ledger messaging protocol lab, and Hyperledger Cacti 3.0 as cross-chain infrastructure. Those later additions are separate from the ten organizations named in April. Read the September update.
