Linux Foundation Decentralized Trust (LF Decentralized Trust) announced eight new general members and two associate members on April 21, 2026. The same announcement made the Open Tokenized Asset Standard (OTAS) an LF Decentralized Trust lab—an open development effort for smart-contract reference implementations, not a declaration that a finished standard has been adopted across the market.
Who joined LF Decentralized Trust?
The April 21, 2026 announcement named eight general members and two associate members. It listed the categories but did not detail or compare the rights attached to each membership type.
| Category | New members |
|---|---|
| General members | Affinidi; Espresso Systems; FairSquareLab; First Person Cooperative; Hashlock; Horizen; Innovation Labs by Identity Digital; Matter Labs |
| Associate members | Advanced AI Society; ERC-3643 Association |
The release also quoted Affinidi CEO Glenn Gore saying the company had contributed “over a million lines of open source code.” That is the company’s attributed statement in the announcement, not an independently audited code count. Read the April announcement.
What is OTAS, and what changed?
OTAS is described as open-source smart-contract reference implementations for tokenized financial instruments. OpenAssets proposed the project, with Sui Foundation/Mysten Labs as an initial sponsor. Its stated goal 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 setting hosted by the organization. LF Decentralized Trust’s remit spans blockchain, ledger, identity, cryptographic, and related technologies. The Linux Foundation described its formation in 2024 as an umbrella for Hyperledger projects and additional open-source software, communities, standards, and specifications for decentralized systems of distributed trust. See the Linux Foundation’s formation announcement.
Does the lab announcement mean OTAS is a finished or adopted standard?
No. The April release establishes that OTAS became a lab and describes its intended scope and goal. It does not establish that the work is finalized, independently validated, adopted across the market, or deployed broadly in production. “Standard” is part of the project’s name; the announcement is evidence of an open development milestone, not proof of universal implementation.

What else did the announcement signal?
Besu implementation support
LF Decentralized Trust said FairSquareLab was already a Besu Certified Service Provider (CSP), and ioBuilders had completed the requirements to become one. The organization describes CSPs as designated companies with proven proficiency and vetted capabilities to help enterprises adopt and deploy its projects. That offers a concrete lead for organizations seeking Besu deployment support, though the announcement does not provide referral terms or compare providers.
A public-service example using Hyperledger Fabric
The release presented Ligue 180, Brazil’s National Violence Against Women Hotline, as a Hyperledger Fabric case study. It said Fabric supports 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 said more than 2,000 women turn to the hotline each day; that figure is attributed to the organization’s release.
