Speaker: Gonçalo Sá of ConsenSys Diligence

Abstract: An intro to Ethereum from a security first perspective. Ethereum is hard, you are building entirely new infrastructure and technology from the ground up, and securing it requires a holistic approach that does more than find bugs in code. In this talk we will discuss why computation is consensual throughout the network, asynchronicity, why security is important, programmable money and how security is achieved in our space.

This talk was recorded Friday, February 14, 2020.

ETHDenver 2020’s content themes included DeFi; DAOs and Token Engineering (TE); Gaming and Usability; Protocols and Interoperability; and Public Good and Social Impact. 

Industry experts also weighed in on topics like decentralization, privacy, identity, non-fungible tokens, scaling, governance, diversity, and arts and culture in blockchain technology.

The 2020 event was February 14-16 in Denver, Colorado and hosted 2000+ blockchain enthusiasts, developers and community members from 50 countries and 50 U.S. states.
