Zero Knowledge

In this episode, we sit down with Howard Wu to explore zkSNARKs, the challenges in the application of this awesome technology, the new ideas emerging for how to scale them and his latest work on DIZK.This is the 2nd in our ongoing series about Zero Knowledge technologies. To get a good sense of Zero Knowledge Proofs, please listen to our introduction to the topic in Episode 21. Howard Wu is an early member of Blockchain at Berkeley, the co-author of Libsnark, and a managing partner of Dekrypt Capital.

In this episode, we dig into what the term smart contract means with our guest James Prestwich. First introduced in 1994 by Nick Szabo, smart contracts have inspired whole ecosystems of companies and projects to start thinking about blockchain in much bigger terms. We explore what the term 'smart contract' means, where it comes from, some use cases and some of the new challenges that come along with it.Follow James on twitter @_prestwich

In this episode we sit down with Ele and Alexis from OSCoin to talk about what they are building and the general problem of open source incentivization. We dig into the incentivization and governance models they imagine for the Open Source world as well as some technical aspects of the platform they intend to build.Links:OScoinSocial Architecture - Building On-line CommunitiesRoads and Bridges: The Unseen Labor Behind Our Digital InfrastructureElinor OstromRadical Markets Uprooting Capitalism and Democracy for a Just SocietyOpen Source Without Maintainers

In this episode, we explore the zcash community and projects implementing zero knowledge proofs at the Zcon0 conference. We discuss exciting ideas generated at the event and cover topics such as bulletproofs and the challenges of network upgrades. Check out the talks and highlights from the conference!

In this introductory episode, we discuss what makes up blocks and block headers. We also cover a bit about state vs history, what exactly makes up a transaction and do a quick intro to a Merkle Tree.

In this episode, we speak with Jack du Rose and Aron Fischer from Colony about governance and open organizations. Colony is building an infrastructure based on the Ethereum blockchain that aims to revamp the way projects and organizations collaborate, promising to make HR and project management more open, fair and efficient.We discuss different ways in which the ideas around colony could be used to created shared and open organisations, how reputation is built as well as discuss their thougths around the general ideas of governance and some of the biggest challenges this creates. For more about Colony - have a look at their site or follow them on twitter!

In this episode, Griff Green shares his experience of working through The DAO hack, the white hat hacker group & Giveth.Through his telling of this story, we are given a front row seat to one of the most exciting events in ethereum and general blockchain history. These events also set the stage for a lot of the decisions, attitudes, rifts and relationships that have since taken hold - from the emergence of the white hat hacker group, the currency split, to the attitude towards governance and immutibility and the community's attitude towards the very concept of a DAO. The story leads us to Griff's latest project Giveth, an ethereum-based project that aims to bring back some of the most inspiring ideas from the era of the DAO, and applies them towards charitable giving.
