Orbinum is a Substrate-based blockchain that combines Zero-Knowledge proofs (Groth16/BN254) with EVM compatibility (Frontier) to enable private transactions through a UTXO-based shielded pool.
Core Components
UTXO-based privacy pool using Merkle trees of note commitments. Supports shield, private transfer, and unshield operations.
On-chain Groth16 proof verification over BN254 curve. Poseidon hash for commitments and nullifiers.
Full Ethereum compatibility via Frontier. EIP-1559 fees, standard precompiles, and custom ZK precompiles.
Native Rust CLI for privacy operations. Arkworks-based proof generation without Node.js dependencies.
