Gitcoin: Open Source Bounties with Kevin Owocki

http://traffic.libsyn.com/sedaily/2018_04_03_Gitcoin.mp3Podcast: Play in new window | Download Most technology companies rely on open source software projects. But open source software projects are often maintained by a group of people that is not affiliated with any particular company. When an open source project develops too much technical debt, it can become a tragedy of the commons. Who is responsible for maintaining these open source projects? This is the motivation for open

Enterprise Smart Contracts with Marley Gray

http://traffic.libsyn.com/sedaily/2018_03_29_EnterpriseBlockchains.mp3Podcast: Play in new window | Download We sign many different types of contracts throughout our lives. We sign a mortgage to get a loan for a house. When we go to the hospital, we sign a piece of paper that defines how our medical data can be shared between organizations. These pieces of paper represent our opting into an agreement that will be mediated and enforced by computer interactions.

Plasma: Smart Contract Scalability with Christian Reitwiessner

http://traffic.libsyn.com/sedaily/2018_03_28_Plasma.mp3Podcast: Play in new window | Download Ethereum is a system for running decentralized smart contracts. In the current implementation of Ethereum, every smart contract gets deployed to every full node. Whenever a user wants to call a smart contract, that smart contract gets executed on each full node–across the entire network. The current model for smart contract execution needs to be made more scalable. In today’s episode, Christian Reitwiessner

ShapeShift Operations with Jon ShapeShift

http://traffic.libsyn.com/sedaily/2018_03_19_ShapeshiftOperations.mp3Podcast: Play in new window | Download A financial exchange is an operationally intensive business. You have customers making a high volume of transactions, your service has to be low latency and highly available, and you are dealing with a lot of money. A cryptocurrency exchange has all of the complexity of a typical financial exchange–and then some additional complexity. ShapeShift is a cryptocurrency exchange that allows users to buy

Web3 with Fabian Vogelsteller

http://traffic.libsyn.com/sedaily/2018_03_14_Web3.mp3Podcast: Play in new window | Download Most applications today run on a cloud provider like AWS. They are built with a framework like Ruby on Rails. They use a set of APIs like Stripe and Twilio for middleware services. This is the era of “web 2.0.” With decentralized systems, we are starting to get a feel for what “web 3.0” might feel like. The futuristic idea of “web 3.0”

Monopolies and Proof of Stake with Karl Floersh

http://traffic.libsyn.com/sedaily/2018_03_12_MonopoliesandProofofStake.mp3Podcast: Play in new window | Download Decentralized applications might someday offer alternatives to modern monopolies. Uber, Airbnb, Facebook, Amazon—all of these services could be recreated on a decentralized stack of technologies like Ethereum, IPFS, and Golem. Fully decentralized services could be more transparent, cheaper, and more efficient. But let’s be realistic. Today, even the simplest applications of fully decentralized blockchains don’t work as well as we need them to.

Proof of Stake with Subhan Nadeem

http://traffic.libsyn.com/sedaily/2018_03_09_ProofofStake.mp3Podcast: Play in new window | Download For a decade, Bitcoin’s proof-of-work system has run without disruption. In a proof-of-work scheme, Bitcoin miners compete to solve a cryptographic puzzle associated with a block of transactions. Every ten minutes, all the Bitcoin miner nodes race to be the first to solve a block of transactions. Only one miner wins each block, meaning the other nodes’ time was ultimately wasted. There is

Cryptoeconomics with Vlad Zamfir

http://traffic.libsyn.com/sedaily/VladZamfir.mp3Podcast: Play in new window | Download A cryptocurrency has a distributed ledger called a blockchain. The blockchain keeps track of every transaction that occurs across the cryptocurrency. This blockchain must stay up-to-date and verified–which requires someone in the network to do that validation. Bitcoin and Ethereum use the proof-of-work algorithm. Miners do computational work to validate the legitimacy of transactions across the network, and in return they are given

Ethereum Platform with Preethi Kasireddy

http://traffic.libsyn.com/sedaily/EthereumBasics.mp3Podcast: Play in new window | Download Ethereum is a decentralized transaction-based state machine. Ethereum was designed to make smart contracts more usable for developers. Smart contracts are decentralized programs that usually allow for some a transaction between the owner of the contract and anyone who would want to purchase something from the contract owner. For example, I could set up a smart contract where a listener sends my smart

DAO Hack with Matt Leising

http://traffic.libsyn.com/sedaily/DAOHack.mp3Podcast: Play in new window | Download The Decentralized Autonomous Organization (DAO) was a digital form of venture capital. It was an ambitious idea–to provide a new decentralized business model for organizing corporations on top of the Ethereum blockchain. Few people in the crypto community were opposed to this premise–but the timeline was short, the code requirements were tremendous, and in retrospect, a vulnerability was inevitable. The DAO launched in

Bitcoin: Fundamental Answers

Bitcoin was underestimated at the start of the week: “Bitcoin” is the naive marketing envoy, the minimum viable decentralized application, the introductory transaction vehicle for distributed, decentralized databases. The revolutionary technology is blockchain. This revolution is rooted in our global culture’s dissatisfaction with centralized, exploitative institutions and software. My belief was that Bitcoin is overrated, blockchain is underrated. This belief has been inverted. Bitcoin is the story of JavaScript all over
