Raspberry Pi-Based Hardware Wallet Solves BSV Cold Storage Woes
Monte Ohrt, a seasoned developer with a history in PHP and cloud architecture, has introduced PiWalletSV - an open-source, air-gapped hardware signing device for Bitcoin Satoshi Vision (BSV). The project was born out of frustration with existing wallet infrastructure that often had issues with BSV support.
Ohrt's solution uses a Raspberry Pi Zero W, a display bonnet, and a camera to create a secure cold storage system. The companion web app runs on a phone or laptop and communicates with the blockchain, while the Pi only signs transactions after verifying the inputs' Merkle proofs against block headers.
Ohrt emphasizes that the device is not perfect, but its air-gapped design provides a significant level of security. He also notes that the project's software and hardware are open-source, allowing anyone to build their own PiWalletSV or modify the existing code.
