Logos Dev Update: March 2026
Your monthly update on the development of the Logos technology stack.
Logos
Logos provides monthly updates on the state of the technology stack and the development of its various modules.
These updates cover all elements of the unified stack, including Storage, Messaging, and Blockchain, as well as related efforts such as Logos Core and AnonComms.
The aim is to give developers a clear snapshot of what has been built over the past month, the current state of key projects, and highlight new initiatives they can get involved in.
For developer-focused highlights on X, please follow Logos Tech. For broader updates on the Logos movement as a whole, stay tuned to the main Logos account.
Below is the Logos Developer Update for March 2026.
Logos Testnet v0.1 Launched
The biggest highlight from March was the launch of Logos Testnet v0.1, marking the first time the full Logos stack has been brought together into a unified, modular system.
Testnet v0.1 is an early release aimed at testing its underlying infrastructure, allowing the core layers — including the Logos Core runtime, networking, and modular services such as blockchain, messaging, and storage — to operate together in a live environment. The testnet provides an early yet functional foundation for testing end-to-end behaviour, validating protocol integration, and exposing APIs under real network conditions.
Developers can now begin actively engaging with the stack through the newly introduced Builder Hub. Via this portal, developers can also contribute via RFPs or idea submissions.
Users can also download Logos Basecamp to run a node and interact with modules, or to experiment with sample applications such as Atomic Swaps and Multisig.
The aim at this stage is to encourage hands-on exploration, surface integration issues, and gather feedback that will inform subsequent testnet iterations, as the system progresses towards improved usability and eventual mainnet readiness.
Logos Privacy Builders Bootcamp
March saw Logos partner with Encode Club to announce the Privacy Builders Bootcamp.
A four-week programme for developers who want to build tools that are private by default and designed for real-world use, the bootcamp will begin on 13 April and will equip developers to create:
• private messaging systems that don’t expose users by design
• peer-to-peer applications that operate without central control
• real tools on a modular, privacy-first stack built for resilience
Participants will have direct support from the Logos team throughout, offering an important first step for those who want to build something new that works for everyone.
Apply now for the Logos Privacy Builders Bootcamp.
𝜆Prize Programme
To encourage developers to get started building on Logos, we have launched the 𝜆Prize initiative, which offers competitive prizes for building applications and tools on top of the Logos stack.
Open challenges range from a censorship-resistant whistleblower app to the development of an anonymous forum with threshold moderation and membership revocation.
Prizes currently range from $400 to $1,200, with the amount for each determined by the scope of the work required.
Browse all the prizes on the Logos Builder Hub.
Logos technology stack updates
Logos Core
During March, work on Logos Core focused on strengthening the platform’s foundations while improving reliability across the stack.
Significant progress was made on architectural refactoring, particularly the abstraction of connection and transport layers and the clearer separation of Qt remote and local implementations. This has been carried through both the core libraries and SDKs, alongside ongoing efforts to simplify dependencies.
A dedicated Nix layer was introduced, which has helped untangle previously cyclical dependencies, making the system easier to reason about and build. Workspace tooling has also been expanded with better multi-repo support, dependency diagnostics, caching, and improved CI behaviour, all of which contribute to a more stable and scalable development environment.
Steady progress is being made on packaging, testing, and application-level polish. End-to-end and async test coverage has increased significantly, supported by new test modules and CI integration. Packaging workflows were refined with better handling of portable versus development variants, improved bundle generation (including macOS), and more robust module and plugin management.
Storage
Work on Logos Storage in March focused on bringing core integration and protocol improvements close to completion while also laying important groundwork for privacy features. Integration with Status reached what is effectively its final stage, with the main pull requests consolidated and rebased.
The team also improved build separation, lifecycle management, and test stability, helping to streamline development and integration. On the block exchange protocol, manifest fetching was decoupled, support was added for multiple downloads per CID, and work started on manifest versioning to support the future evolution of the protocol.
A new testnet file-sharing client was released, introducing fixes and interface improvements, and the team began exploring end-to-end testing approaches, including a prototype JavaScript-based test harness.
Collaboration with the AnonComms team led to initial designs for anonymous file download and publishing via the mix protocol, alongside ongoing work on RLN and related security components.
Integration with Logos Core continued with added support for instance IDs, expanded testing, and UI refinements, contributing to a more stable and flexible foundation for future development.
Messaging
Logos Messaging focused on iterating Logos Chat and laying the groundwork for broader integration. A Rust client for Logos Chat was implemented, and the embedded legacy Waku module was replaced with the Delivery module for message transport.
Initial versions of the Health API and debug API were completed, alongside enhancements to configuration and security, particularly around node management. A hotfix release (v0.37.2) was shipped and deployed, while preparation for the next release (v0.38.0) continued, including updates to bindings and interoperability tests.
The team also resolved significant technical issues last month and introduced new features such as the ListConversations API, improved chat history handling, and the first Chat SDK Developer Preview.
Documentation and developer experience also improved, with API docs, readme updates, and initial code examples underway. Exploratory work began on group conversations, MLS integration, and longer-term architecture, including proposals for project restructuring and state persistence.
Blockchain
In March, the Logos Blockchain team made steady progress on developing core components beyond the launch of testnet v0.1.
The team formalised adversarial models for data availability, including recoverability thresholds and failure probabilities, and validated these against simulations. Total stake inference was improved through integrating a mathematically derived model for honest slot utilisation, which provides a more rigorous basis for analysing network behaviour. Ongoing development on Cryptarchia saw bootstrapping and synchronisation protocols being refined, as well as ongoing specification work and fast bootstrapping proposals.
The Blend Protocol received several reliability upgrades, making it better able to handle duplicate messages and improving both session stability and peer management. The testing framework was expanded and refactored into a reusable library, supported by stress testing and profiling work to identify bottlenecks such as memory growth issues.
The team also optimised the sequencer and indexer for the Logos Execution Zone (LEZ) architecture and enabled state caching for greater efficiency. Early work has begun on delivering a distributed sequencer and the tokenomics implementation.
AnonComms
March saw the AnonComms team focus on advancing core protocols. The biggest highlight was the release of Zerokit v2.0.0, which introduced support for burning multiple message IDs within a single RLN proof alongside optimised proof generation. This builds on earlier work to implement multi-burn RLN functionality and associated slashing mechanisms, bringing the feature close to full integration.
When it comes to the network and discovery infrastructure, the team has implemented a capability discovery module and protocol, which it is integrating and testing internally within Logos Delivery.
Work on the libp2p mixnet, group messaging, and de-MLS is ongoing and evolving. AnonComms has also begun work on oracle systems, RLN membership allocation services, and service incentivisation.
Research and DST
Over the past month, the DST team focused on strengthening core systems, advancing key research streams, and improving operational visibility. Notable progress was made in DHT observability and diagnostics, delivering deeper insight into Kademlia DHT behaviour, expanding blockchain devnet tooling, and carrying out detailed memory analysis.
This was supported by the rollout of new monitoring dashboards and health tooling, helping to improve reliability and performance across distributed environments. A security audit of the Logos Execution Zone (LEZ) was also initiated.
Tokenomics work saw the digital twin reimplementation completed alongside a dedicated dashboard. The first version of the LEZ fee-market model was defined, and work continued on the stablecoin RFP and other token-related activity.
Additionally, new AMM research was published, and the exact-output swap implementation was finalised. The team also launched a dedicated repository for programs essential to the Logos Execution Zone.
Documentation
With the rollout of Logos Testnet v0.1, much of the documentation around the Logos stack has been updated to onboard developers to this early initial version of the network.
Documentation that provides an overview of the Logos stack and explains the various avenues for developers and users to get involved can be found on GitHub. This documentation is under development and evolving, so expect further updates in the future.
