Decentralized Objects with Martin Kleppman

http://traffic.libsyn.com/sedaily/CRDTs_Decentralized_Files.mp3Podcast: Play in new window | DownloadThe Internet was designed as a decentralized system. Theoretically, if Alice wants to send an email to Bob, she can set up an email client on her computer and send that email to Bob’s email server on his computer. In reality, very few people run their own email servers. We all send our emails to centralized services like Gmail, and connect to those centralized

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

Blockchain Building with Daniel van Flymen

http://traffic.libsyn.com/sedaily/BuildaBlockchain.mp3Podcast: Play in new window | Download A blockchain is a data structure that provides decentralized, peer-to-peer data distribution. Bitcoin is the most well-known blockchain, but in the next decade we will see many more blockchains. Most listeners probably know that you could just fork the code of Bitcoin to start your own blockchain–but wouldn’t it be nice to know how to build a blockchain from scratch? Daniel van Flymen

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

Coinbase Antifraud with Soups Ranjan

http://traffic.libsyn.com/sedaily/CoinbaseAntifraud.mp3Podcast: Play in new window | Download Coinbase is a platform for buying and selling digital currency: bitcoin, ethereum, and litecoin. Every payments company deals with fraud, but a cryptocurrency company has a harder job than most payments companies, because bitcoin transactions are anonymous and non-reversible. This is in contrast to a bank, which deals with a regulated, reversible transaction system. Soups Ranjan is the director of data science at

Fighting Fraud at Coinbase with Soups Ranjan

http://traffic.libsyn.com/sedaily/SoupsPresentation.mp3Podcast: Play in new window | Download A cryptocurrency exchange faces a uniquely difficult fraud problem. A hacker who steals my credentials can initiate a transfer of all my bitcoin to another wallet, and it is a non-reversible, non-identifiable payment. So it is really important to prevent those kinds of fraudulent transactions. At the third Software Engineering Daily Meetup, Coinbase director of data science Soups Ranjan explained how Coinbase stays

Computer Logic with Chris Dixon

http://traffic.libsyn.com/sedaily/ChrisDixon.mp3Podcast: Play in new window | Download The history of computing can be thought of as a series of ideas rather than objects. From Aristotle’s formalization of the syllogism, to Alan Turing’s model for an all-purpose computing machine, to Satoshi Nakamoto’s distributed transaction ledger–these breakthroughs did not come in the form of polished, tangible objects. In fact, the objects which end up changing computing fundamentally are often built from ideas

21 with Balaji Srinivasan

http://traffic.libsyn.com/sedaily/twentyone_edited.mp3Podcast: Play in new window | Download Bitcoin is underappreciated even to this day. The public focus is usually on the speculative value, but Bitcoin has functional value as a technology platform. If I want to make 100 transactions with my bank for 1 cent, the bank won’t allow it. Our current financial infrastructure is not set up for micropayments. Bitcoin is built with micropayments in mind. As Bitcoin works
