Joseph has been developing cryptographic algorithms for secure peer-to-peer transactions since 2004. He played a role in creating the Linkable Ring Signature, which Monero, a cryptocurrency similar to Bitcoin, used to add a layer of privacy to the transaction process.
As cryptocurrencies proliferate and become more mainstream, Joseph is staying on the cutting edge. He is part of a team developing a new cryptocurrency system called Hcash that will enable secure transactions between different cryptocurrencies.
