Privacy-first consensus for decentralised applications and social institutions.
Key Repositories:
LOGOS-BLOCKCHAIN — Logos Blockchain main repository
LOGOS-EXECUTION-ZONE — Programmable blockchain with parallel private state
LEZ-PROGRAMS — Essential programs for the Logos Execution Zone
The Logos testnet is currently live. The testnet includes the LEZ sequencer, a block explorer, and demo applications for atomic swaps and ZK-multisig. It is designed for backend validation and developer experimentation.
Logos Blockchain is a proof-of-stake layer-1 with privacy built into the consensus mechanism itself, rather than added at the application layer. Block proposers are anonymous and transactions are private by default. The chain supports application-specific execution environments called Sovereign Zones, which will be connected for interoperability.
Most proof-of-stake systems reveal who proposed each block, creating a target for censorship, bribery, and coercion. Logos solves this with Cryptarchia, a private proof-of-stake mechanism in which block proposers are selected through a private lottery and anonymised through Blend, a mixnet-based protocol. Validators take part in consensus without revealing their identity during block proposal — a privacy guarantee most blockchains cannot offer.
The LEZ is the first Sovereign Zone, serving as the primary execution environment for applications on the Logos blockchain. Separate but interoperable public and private state allows applications to operate across both transparent and privacy-preserving accounts without changing their logic. Privacy is enforced by the protocol itself through zero-knowledge proofs (ZKPs).

The Logos technology stack is a unified ecosystem of distinct modules. The entire stack is modular so developers can assemble their own Logos-based platform with a different selection of modules.

LOGOS EXECUTION ZONE (LEZ)
PRIVATE PROOF-OF-STAKE CONSENSUS
Anyone can build pluggable modules that can communicate with each other over the same infrastructure.
This layer handles how Logos nodes find each other, establish connections, and communicate while preserving user privacy.
A runtime that handles the essential primitives every application needs: loading modules, managing their lifecycles, and letting them talk directly to each other in a secure way.
