- 2. Antitrust Policy Notice Linux Foundation meetings involve participation by industry competitors, and it is the intention of the Linux Foundation to conduct all of its activities in accordance with applicable antitrust and competition laws. It is therefore extremely important that attendees adhere to meeting agendas, and be aware of, and not participate in, any activities that are prohibited under applicable US state, federal or foreign antitrust and competition laws. Examples of types of actions that are prohibited at Linux Foundation meetings and in connection with Linux Foundation activities are described in the Linux Foundation Antitrust Policy available at linuxfoundation.org/antitrust-policy If you have questions about these matters, please contact your company counsel, or if you are a member of the Linux Foundation, feel free to contact Andrew Updegrove of the firm of Gesmer Updegrove LLP, which provides legal counsel to the Linux Foundation. 2

- 8. 8 Web3 shifts power to users through self- sovereign identity, and open-source protocols that eliminate single points of failure.
- 10. 10 In Web2, trust relies on corporations and intermediaries.
- 11. 11 In Web3, trust is established through verifiable cryptographic proofs, smart contracts, and decentralized governance, ensuring transparency and security without needing a central authority.
- 12. Open Source that is openly developed is needed for decentralized technologies

- 25. Hiero is an open source, vendor-neutral distributed ledger technology used to build the Hedera public ledger.
- 26. 26 Hiero overview Hedera’s core network software, including the Hashgraph consensus mechanism, now operates as Hiero under Linux Foundation Decentralized Trust. Why LF Decentralized Trust? Promotes open collaboration, vendor-neutral governance, and interoperability through shared resources and global outreach. Key Features ● High Performance: Powered by Hedera’s aBFT Hashgraph for unmatched speed, security, and scalability. ● Developer Tools: Includes SDKs (Java, Go, Rust), JSON-RPC Relay, and an Explorer Interface for easy integration and access. ● Open Source: Apache 2.0 license for community-driven innovation and transparency. Benefits for Developers and Enterprises ● Collaboration: Engage with LF Decentralized Trust’s vast ecosystem ● Adoption: Bridging Web2 and Web3 with resources for diverse developer backgrounds.
- 27. a new open-source ecosystem focused on key management and digital signature protocols, including technologies like Multi-Party Computation (MPC), Threshold Signature Schemes (TSS) and other state-of-the-art protocols in public key cryptography
- 28. 28 Lockness overview Open-source ecosystem for key management and digital signature protocols. Focus areas: Multi-Party Computation (MPC), Threshold Signature Schemes (TSS), Zero-Knowledge Proofs (ZKP), and advanced cryptographic techniques. Challenges: Traditional key management faces vulnerabilities (e.g., key exposure/loss, centralized key storage makes for juicy attack targets); slow adoption of MPC in institutional finance due to lack of standards. Solutions: Secure key management via distributed cryptography; unified effort for trusted open-source development. Key Contributions ● Robust libraries for MPC, threshold cryptography, and ZKP: ● Round-based, generic-ec, fast-paillier, cggmp21, and more. ● Fully audited, Apache 2.0 licensed, and community-driven. Project Vision ● Democratize access to secure cryptographic protocols. ● Simplify implementation for developers and institutions. ● Establish global standards for cryptographic security.
- 29. CREDEBL is an open source Decentralized Identity & Verifiable Credentials Management Platform
- 30. 30 CREDBL overview CREDEBL is a cutting-edge, population-scale platform designed to simplify and secure the management of Decentralized Identity and Verifiable Credentials Key Attributes ● Multi-Tenant, Agent-Agnostic, and Ledger-Agnostic ● Supports diverse Verifiable Data Registries (VDRs), DID methods, and Verifiable Credential formats. ● End-to-End Credential Lifecycle Management ● Enables organizations to issue, verify, and manage digital credentials. ● Scalability for Population-Scale Implementations Optimized for use cases like: ● National Digital IDs ● Digital Travel Credentials ● Mobile Driver’s Licenses (mDLs) ● Academic Credentials ● And more… Recognized as a Digital Public Good (DPG)- Endorsed by the Digital Public Good Alliance (DPGA).

- 36. 36 Scope The scope of the proposed lab fits with the LF Decentralized Trust Mission Name The proposed name is appropriate (e.g., not too generic, confusing, or conflicting with other labs or projects, etc.) Proposers Proposers need to be active members of the our technical community (as defined by the charter)
- 37. 37 Propose the lab Fill out the proposal template and save it into the labs subdirectory under the name of your lab Pull request Submit a pull request Wait for review Lab stewards will then review your proposal Proposal process Fork the repo Fork the github repository and name the lab.
- 38. 38 What to do after starting a new lab or project Consistently engage with community members to find new users and contributors Projects & labs that haven’t engaged with community members have gone inactive! LF Decentralized Trust staff can help. There are a range of ways you can engage including: Host a workshop Speak at a Meetup (either in person or remotely) Communicate on public channels (mailing list, Discord, calls) Collaborate with the community Full Deck: Community Building Resources for Maintainers

- 43. 43 turning a lab into a project The FireFly code started in Labs to give the original developers time to adjust their internal development processes to fit an open source environment This also gave the developers the infrastructure to start engaging with community members through community calls, meetups and chat After a few months, the developers put a project proposal together and demonstrated they were following open source best practices and there was interest in the community in their work
- 44. 44 “Going open source, open governance enabled us to tap into the power of the community in a way that no other approach could touch. When we did the analysis, there were just too many benefits to going open source versus keeping the technology closed.” Case study The Hyperledger FireFly story Steve Cerveny, Founder and CEO of Kaleido Read case study ?
