Analyzing the cryptographic requirements of Lightning Network infrastructure and implementing hardware-isolated channel management.
High-volume routing nodes process thousands of Hash Time Locked Contracts (HTLCs) per minute. Traditional offline cold storage cannot service this demand. BitHSM bridges high throughput with physical hardware protection by implementing the Lightning Network BOLT specifications inside an isolated hardware microkernel.
As payments hop across the network, routing nodes peel off layers of Sphinx encryption using ephemeral ECDH shared secrets. BitHSM hardware accelerators execute ChaCha20-Poly1305 and secp256k1 scalar multiplications at wire speed, ensuring routing latency remains imperceptible to network clients.
BitHSM maintains an encrypted, tamper-evident channel state database, automatically preparing justice transactions that can be broadcast immediately if a counterparty attempts to cheat by publishing a stale commitment state.
