Tommy Liu

Blockchain Engineer

Summary

I was introduced to the Web 3.0 ecosystem during my time in Latin America. As I traveled, I connected with incredible people and witnessed firsthand how their institutions had chronically disenfranchised them. This experience inspired me to join the effort of building a new kind of institution, one governed by code, impartial and trustless. Seeing that western nations and central banks are headed towards a similar path, where hyperinflation and financial exploitation take precedent over meaningful reform, only reinforced my belief that this is where the most impactful and meaningful work lies.
