The economic engine
for sovereign computing
Zenith completes Urbit's decentralized stack with native consensus and economic primitives, enabling truly sovereign applications that were never possible before.
Testnet launching Q2 2026
Web3 hasn't delivered its promise
Fragmented Stack
Building decentralized apps requires stitching together 7+ incompatible systems: compute, storage, identity, consensus, and more.
Centralized Dependencies
Applications claiming to be "decentralized" run primarily on centralized infrastructure. Less than 5% of the stack is genuinely decentralized.
No Shared Truth
Without protocol-level global state, applications fragment across multiple systems with no unified view of truth.
One integrated platform
Zenith + Urbit combines identity, computation, storage, and consensus into a single developer platform, making arbitrary decentralized applications actually viable.
Azimuth PKI
4.3 billion unique, on-chain identities
Arvo OS
Networked, deterministic personal servers
Zenith
Native consensus & economic primitives
Built for the sovereign future
Scry Oracle
Adds Byzantine Fault Tolerance to Urbit's native data namespace. Stores cryptographic hashes on-chain while keeping data off-chain, enabling 3,840x cost advantage vs. Ethereum for state updates.
Three-Tier Consensus
Maps Urbit's address space to blockchain roles: Galaxies (256) validate blocks, Stars (65K) build transactions, Planets (4.3B) are Sybil-resistant user identities. Natural decentralization from launch.
Guaranteed Blockspace
Every Galaxy receives fixed blockspace allocation for their Stars through enshrined Proposer-Builder Separation. No more gas wars or unpredictable fees. MEV is transparent and fairly distributed.
Light Contracts
Edge computation model that separates consensus from execution. On-chain: cryptographic commitments. Off-chain: deterministic logic runs locally. Enables applications impossible on traditional chains.
Own your digital life
Not your keys, not your compute. Truly own your data and applications.
One identity across all applications, both financial and social.
Control your community's algorithms and interfaces.
Can't be deplatformed, censored, or have your data sold.
Monetize your own data selectively, not the platforms you use.
Ship features, not infrastructure
Build full-stack decentralized applications in one unified environment. No more wrestling with incompatible systems.
Unified Environment
From consensus engine to server to OS to interface, everything in one integrated platform.
Native Identity
Never worry about Sybil attacks or bot spam. Every user has a costly, verifiable identity.
Free Deployment
Don't pay anything to deploy a smart contract. Light contracts run at the edge with no gas.
Value Capture
Capture the economic value of your creations without any platform intermediating.
