A secure, distributed and scalable infrastructure for remote generation and use of cryptographic keys

This paper outlines an ad-hoc architectural design and a practical implementation of a secure, distributed, fault tolerant and scalable infrastructure comprised of a distributed network of electronics hardware systems that remotely generate cryptographic keys, store them, digitally sign cryptographic transactions based on such keys, and record the transactions on a blockchain. The proposed solution is suitable to service both crypto-finance and non-finance applications, and the physical infrastructure is designed to be implemented using off-the-shelf industrial electronics, which further sustains the already scalable-by-design infrastructure architecture.
