Octra is a Switzerland-based Layer 1 blockchain network founded in 2021 that focuses on privacy-preserving computation using its proprietary Hypergraph Fully Homomorphic Encryption (HFHE) scheme. The platform combines a blockchain, an encrypted compute layer, and isolated execution environments called Circles, allowing programs written in multiple languages to process encrypted data without decryption. Development milestones include an internal prototype released in October 2023, a public testnet launched in June 2025 that processed over 100 million transactions with a peak throughput of 17,000 tps, and a mainnet alpha released in December 2025, with further mainnet phases planned for 2026.
Octra uses HFHE, an in‑house hypergraph‑based fully homomorphic encryption scheme to enable encrypted computation.
The network supports isolated execution environments named Circles, which can host programs in AppliedML, Rust, C++, OCaml, or WASM.
Octra’s testnet, launched June 2025, processed more than 100 million transactions and achieved a peak of 17,000 transactions per second.
The native utility token, OCT, is used for transaction fees, payment for compute resources, and validator rewards, and is described as a non‑security token.
Octra’s codebase is primarily written in OCaml and C++, with public repositories and tooling progressively open‑sourced.
Octra was founded in 2021, with an internal prototype released in October 2023, a public testnet launched in June 2025, and a mainnet alpha launched in December 2025.
HFHE is Octra’s proprietary fully homomorphic encryption scheme that allows the network to compute on encrypted data without decrypting it, enabling privacy‑preserving smart contracts and data processing.
Applications can be built in AppliedML (the native language), as well as Rust, C++, OCaml, or WebAssembly (WASM).
Circles are isolated execution environments that host programs and encrypted data storage, ensuring that code and data remain confidential during processing.
The OCT token powers the network by facilitating transactions, paying for computational resources, and rewarding validators, and is characterized as a non‑security token.
