Octra is a privacy-preserving Layer-1 blockchain built from the ground up to execute encrypted computation on-chain. Unlike traditional blockchains, where data is either fully public or hidden using external techniques (ZK proofs, MPC, or trusted hardware), Octra allows:
  • Transactions
  • Smart contract logic
  • Onchain state
to remain encrypted at all times, while still being executed and verified by the network.
In short: Octra computes on data it cannot see.
0xio is designed specifically to expose this capability safely to end users.

​
Fully Homomorphic Encryption (FHE)

Fully Homomorphic Encryption (FHE) is a cryptographic primitive that allows arbitrary computation to be performed directly on encrypted data, without decryption. On Octra, this enables:
  • Validators to process transactions without seeing balances or inputs
  • Smart contracts to execute logic over private state
  • Verifiable outputs with no data leakage
  • User data privacy enforced by cryptography, not trust
This is not privacy through obfuscation or offchain assumptions. It is privacy enforced at the execution layer.

​
Hypergraph FHE (HFHE)

Traditional FHE is prohibitively slow. Octra addresses this with HFHE (Hypergraph Fully Homomorphic Encryption). HFHE differs fundamentally from lattice-based FHE approaches by:
  • Mapping encrypted data onto hypergraph incidence structures
  • Keeping encryption noise localized, not global
  • Enabling massive parallel execution and bootstrapping
  • Remaining CPU-friendly without specialized hardware

​
What This Unlocks

  • Parallel encrypted logic gate evaluation (AND / OR / XOR)
  • Sub-10ms encrypted bootstrapping
  • Practical encrypted throughput at Layer-1 scale
0xio abstracts these mechanics so users and developers benefit from encrypted execution without interacting with cryptography directly.

​
Validator Work: Real Computation, Not Waste

Octra does not rely on hash-based mining. Validators are rewarded for performing the actual encrypted computation required by the network:
  • Executing encrypted transactions
  • Running encrypted application logic
  • Maintaining encrypted state
  • Participating in validation and key management tasks
There is no expendable work.
Execution itself is the work being secured.

​
Circles: Encrypted Execution Environments

Octra introduces Circles, isolated, on-chain execution environments that function like encrypted backend services. Within a Circle, developers can:
  • Deploy complex application logic
  • Run code written in Rust, C++, or WASM
  • Store and compute over encrypted state
  • Control access without exposing raw data
Circles are best understood as: Private, verifiable, on-chain compute containers They scale independently, remain isolated, and inherit encrypted execution by default.

​
Networks

Octra currently operates two public networks: Devnet is the primary testing ground for FHE-powered features: encrypted balances, private transfers, smart contract development, and the full encrypt/decrypt/claim flow. All 0xio products (extension, mobile app, desktop) support switching between networks.

How 0xio Fits In

0xio sits above Octra’s execution layer.
  • Octra provides encrypted computation
  • 0xio provides usable interfaces, wallets, SDKs, and applications
The 0xio product suite includes:
  • Browser Extension: Primary gateway for web-based interaction
  • Mobile Wallet: Privacy on the go with biometric security
  • Desktop Wallet: Native PVAC engine that accelerates FHE operations
  • DEX: Cross-chain swaps and same-chain CLMM pools
  • Bridge: Trustless OCT to wOCT bridge between Octra and Ethereum
  • SDK: TypeScript SDK for DApp integration
Users interact with 0xio. 0xio securely interfaces with Octra.
