Blockchain Security Researcher
Lev Menshchikov
Co-Founder at Protectorium.com
Over the years, I remain convinced that advanced cryptography and distributed systems can make a significant contribution to protecting private property in cyberspace. Moreover, I believe cryptography is the ultimate weapon in the fight against financial authoritarianism and mass surveillance.
For the last 4+ years, I have been designing, building, and ensuring the security of smart contracts, cryptographic and distributed applications as a Blockchain Security Researcher.
Besides work, I enjoy martial arts, hiking, rock climbing, parachuting, and firearms.
