BIP-340 Schnorr Signatures & Taproot Script Trees in Silicon

Engineering custom ASIC coprocessors executing constant-time Schnorr signatures and Merkleized Alternative Script Trees (MAST).

Schnorr vs. ECDSA in Hardware Architecture

BIP-340 Schnorr signatures offer significant mathematical advantages over legacy ECDSA, including linearity, batch verification, and reduced signature size (64 bytes). BitHSM implements dedicated modular arithmetic units optimized for secp256k1, enabling sub-20 microsecond signing.

MuSig2 Multi-Signature Aggregation

BitHSM natively supports the MuSig2 protocol, allowing enterprise multi-signature signers to produce a single, privacy-preserving 64-byte on-chain signature that looks identical to a standard single-key Taproot transaction.

BIP-340 Schnorr Speed: Executing 64-byte Schnorr signatures in under 18 microseconds with zero timing leakage.
Batch Verification: Verifying up to 50,000 Schnorr signatures concurrently using linear combination algorithms.
Key Aggregation (MuSig2): Hardware execution of multi-party Schnorr key aggregation protocols.
Taproot Tweak Verification: Proving that internal public keys are correctly tweaked with Merkle root script commitments.
