Logos Dev Update: February 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 will encompass all elements of the unified stack, including Storage, Messaging, and Blockchain, as well as other projects such as Logos Core and AnonComms.
We aim to provide developers with a brief snapshot of what has been built in the last month, the state of various projects, and highlight new initiatives with which they can become involved.
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 February 2026.
Preparing for Logos Testnet v0.1
The development of the Logos stack prioritised the initial launch of Logos Testnet v0.1, with the goal of delivering a public testing build to those interested in participating as node operators at Parallel Society - a collaboratively organised hackspace and cultural event hosted in Lisbon, Portugal.
The Logos Testnet v0.1 remains under active development and is designed to validate the core backend infrastructure rather than deliver a polished user or developer experience.
The primary focus is on testing the Blockchain implementation, including the Logos Execution Zone (LEZ), alongside foundational features of the Storage and the Messaging stack. UX and DevEx are intentionally limited, and developers can build and test applications on Logos Core using simple, alpha-stage interfaces.
Operators can run a Logos node and choose which modules they would like to install and manage, providing an opportunity for early adopters and supporters to build out the network.
Logos Testnet v0.1 ships with a set of sample applications in alpha, as well as modules for Blockchain, Storage, and Chat. These modules are independent but interoperable, communicating through well-defined interfaces exposed by Logos Core.
The newly released Logos Basecamp is a complete distribution designed to let users easily interact with simple apps built on the foundational modules. It bundles the kernel, the default modules, and UI packages into a usable product.
More information is available on the Logos Builders Hub.
Launch readiness of Logos Testnet v0.1 was the main focus of development in February, and contributors are also scoping out the features of the next version of the testnet, which will follow in the coming months.

Logos technology stack updates
Logos Core
Over the past month, work on Logos Core has focused on strengthening its modular architecture and improving packaging and portability.
A new logos-module library and supporting tools were introduced to standardise how modules are built, loaded, and accessed, and updates were made to logos-liblogos to improve module handling and support automatic dependency loading. Various modules and libraries were also updated to use the new tooling, and build issues across Linux and macOS were addressed.
Alongside this, the package manager was refactored into a reusable library and enhanced to better handle dependencies, request queuing, and distributed builds. The packaging and bundling process was improved, particularly for portable modules and Qt components on Linux and macOS.
In February, the UI of the Logos Core app was also updated according to the new design, and it continued its transition towards QML-based interfaces.
Storage
Last month, work on Logos Storage focused on improving file-sharing protocols and advancing research related to file-sharing over the anonymising Mix protocol.
The teams also refactored the Storage protocol’s archive and storage architecture to introduce clearer abstractions, improved lifecycle management, and cleaner separation between backends.
Progress was also made on the new block exchange protocol, including decoupling manifest fetching, enabling multi-download per CID, and laying the groundwork for manifest versioning. We released a new version of the testnet file-sharing client and made various fixes to improve stability.
The team also completed initial designs for anonymous downloading and publishing using the mix protocol, and continued ongoing work on RLN proofs and related privacy research. The Logos storage module was also finalised, now with support for headless mode, expanded SDK bindings, and a more polished UI with onboarding and dashboard improvements.
Messaging
Over the past month, work on Logos Messaging has focused on delivering the first developer preview of the Chat module, strengthening messaging delivery, and progressing general integration with Logos Core.
Various improvements were made to the Chat library, addressing everything from payload handling and conversation management to identity handling and the addition of new APIs. Safer FFI interfaces were also introduced, and bindings were expanded to support SDK integration.
Dedicated Chat and Chat UI modules were added to Logos Core ahead of the launch of Testnet v0.1, and several enhancements were made to simplify installation and improve documentation for these modules. Changes were made to support multiple conversations and improve chat history handling, and the messaging stack was updated to use the logos developer fleet for testing.
A new version of the Logos Delivery module was deployed, as was the first version of a Health API to monitor node status and connectivity. The supporting infrastructure and repositories have also been reorganised appropriately, and improved build tooling, such as Nix flakes and Nimble integration, was introduced.
Blockchain
Logos Blockchain made significant progress last month, from improving its core protocol components to introducing better deployment tooling, monitoring endpoints, and Docker-based workflows in its latest release version.
The testing framework was also expanded with stronger integration tests, live network connection modes, and improved cluster tooling to support more realistic devnet environments.
Development continued on Bedrock and the Cryptarchia implementation, and the Blend networking layer was integrated with real proofs and optimised for stability. Research also progressed on permissionless participation and data availability sampling, with analysis showing that under the current parameters, the probability of the network accepting blocks built on unavailable data is effectively negligible.
The team also worked to integrate the Logos Execution Zone (LEZ) sequencer, indexer, and block explorer with the Bedrock node to enable end-to-end testing. A SQLite-based demo zone and REPL were built to demonstrate the functionality of the execution environment.
Blockchain documentation was expanded with updated READMEs, tutorials for the LEZ testnet, and guides for running a node on the Logos Testnet v0.1.
AnonComms
February saw the AnonComms team make significant progress in the development of an anonymous messaging layer underpinning the infrastructure of the Logos technology stack.
An RLN prover module was developed that enables gasless L2 transactions and leverages a decentralised slashing model. RLN infrastructure was also enhanced to deliver multi-burn RLN proofs, improvements to membership allocation and identity management, and authenticated connections between provers and slashing services.
The team also specified and implemented a p2p capability discovery protocol for Logos Core, along with test coverage and metrics. The development of the mixnet continued with the deployment of DoS and Sybil protection mechanisms, and a demo chat application built on this infrastructure is being dogfooded internally. The AnonComms team also made progress on protocols to enable secure group p2p communication, implementing the first version of a de-MLS API, which will be available as a module for Logos Core.
Research
Research at Logos has focused, amongst other work, on strengthening analytics. Business intelligence work expanded monitoring and reporting through new dashboards for website analytics, network activity, and testnet metrics, while improvements to financial reporting introduced automated validation and resolved missing transaction data.
Infrastructure and developer tooling also progressed. Updates to large-scale simulation and deployment tools improved testing environments for distributed systems, while networking work stabilised key components in nim-libp2p and expanded Logos networking modules with better cross-platform support.
Infrastructure updates improved validator and node operations, monitoring, and CI automation, while security work encompassed an audit of Keycard firmware and broader vulnerability triage. In addition, tokenomics research advanced the Logos digital twin model and contributed to the tokenomics section of an early internal draft of the blockchain litepaper.
Documentation
Work continued this month on improving the developer experience by bringing scattered documentation into a clearer, more unified structure. The goal of this ongoing effort is to make the Logos technology stack easier to understand and navigate, while establishing consistent terminology and improving how the different protocol layers fit together.
An evolving index of documentation is currently available on GitHub. It is still under active development and continues to be refined. A list of open issues and regular highlights can also be found at roadmap.logos.co.
As part of this work, the team has migrated the existing RFC collection to the new Logos Improvement Proposals (LIPs) repository. The LIPs site provides a central and reviewable index of specifications across the messaging, storage, and blockchain layers.
Documentation will continue to be released and optimised throughout 2026. Upcoming updates will include developer guides designed to support onboarding and better reflect the current state of the Logos ecosystem.

Logos Broadcast Network and Circles
February saw Logos contributors continue to host online and IRL Circles around the world, expanding community engagement and solving real-world problems with sovereign technology.
We have also continued to publish live content and engagements through the Logos Broadcast Network.
The Broadcast Network delivers regular programming, including Dev Club sessions, Weekly Technical Updates, and live discussions on movement-focused topics. The Logos team has also begun to host regular office hours every Friday at 14:00 to interact with developers and help them build tools and apps using the technology stack.
