We're joined by Igor Barinov, the tech lead of the POA Network. The POA Network achieves a reduction in transaction costs by many orders of magnitude by having a set of trusted validators. All validators must be US public notaries, so their identities are known and legal recourse against them can be taken in the offchain world. We also talk about the xDai network, which enables Dai transactions on a POA chain: Dai are transferred into a smart contract on the mainnet and then become available to be transferred at much lower cost on the POA Network. Similarly, they can be transferred out of the xDai network and become available again on the mainchain. We talk about use cases, governance, and limitations. Topics covered in this episode: Igor's background and how he got into blockchain The POA network setup and how to become a validator What informs design decisions and how to find suitable notaries The consensus mechanism on the POA Network The role of the POA token The xDai network and its purpose The role of the DPOS token Use cases of POA and xDai Networks Episode links: POA Network website POA products overview xDAI Chain POSDAO White paper Ocean Protocol releases own POA network Beginners guide: What's the POA network Sponsors: StarkWare Sessions: September 16th in Tel Aviv – 20% off with the code EPICENTER - https://epicenter.rocks/starkware Trail of Bits: Trust the team at the forefront of blockchain security research - https://trailofbits.com Vaultoro: Trade gold to Bitcoin instantly and securely starting at just 1mg - http://vaultoro.com This episode is hosted by Meher Roy & Friederike Ernst.

We’re joined by Ameen Soleimani, Co-founder and CEO of SpankChan. From his humble beginnings at ConsenSys, he went on to create SpankChain in 2017 at the height of the ICO boom. The project aims to create a better and safer environment for sex workers by removing the intermediaries who take significant commissions on their revenues. SpankChain’s initial product, an adult cam platform, allows users to pay performers in crypto with a native asset over sophisticated payment channels. More recently, Ameen headed a project called Moloch DAO, a decentralized autonomous organization with the goal to fund Ethereum 2.0 development. Moloch has but few simple functions: making proposals, voting on proposals, and exiting. This simple design, heavily inspired on “The DAO” of 2016 has attracted funding from Vitalik Buterin, Joe Lubin and other prominent community members. Topics covered in this episode: Ameen’s background as an early ConsenSys employee working on payment channels Why Ameen decided to found SpankChain and how the project has evolved since its inception What is Moloch DAO and why he decided to launch it The mechanism behind Moloch and how it compares to other DAOs How one becomes a member of Moloch and participates in governance The simplicity of Moloch DAO and its essential functions How Moloch DAO scales and its intended lack of a smart contract upgrade mechanism The attention and funding the project has already received Proposals already made on Moloch, including YangDAO, and their utility to the ecosystem Ameen’s views on the broader Ethereum space, his outlook on Eth 2.0 and the future of the project Episode links: Moloch DAO Moloch Ventures · GitHub Moloch DAO white paper Moloch Summoning Guide The State of Ethereum 2.0 report A Study of Libp2p and ETH2 A Call for a Temporary Moratorium on The DAO YangDAO Ameen Soleimani on Twitter Moloch DAO on Twitter SpankChain DappCon – 20% off with the code “EpicenterDappcon2019” Epicenter Meetup at Berlin Blockchain Week – Thu 22 Aug 2019 Berlin Blockchain Week 2019 Sponsors: Azure: Deploy enterprise-ready consortium blockchain networks that scale in just a few clicks - http://aka.ms/epicenter Trail of Bits: Trust the team at the forefront of blockchain security research - https://trailofbits.com This episode is hosted by Sebastien Couture & Friederike Ernst.
