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
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

At NYU, he works as an assistant professor exploring cryptography and security. His YouTube lessons teaching Bitcoin have hundreds of thousands of views. His material offers clear explanations of how Bitcoin works. Since Joseph has a clear understanding of the objective facts around Bitcoin, he is the perfect person to ask
http://traffic.libsyn.com/sedaily/2018_02_26_BitcoinTransactions.mp3Podcast: Play in new window | Download Bitcoin is an immutable, append-only blockchain ledger that reaches consensus through proof-of-work. The contents of the ledger are financial transactions–people sending and receiving Bitcoin currency to each other. Since Bitcoin, there have been other cryptocurrencies that have similar properties–like Ethereum and the IPFS/Filecoin system. Similar to Bitcoin, they use a decentralized, proof of work based system with a currency reward system–but the ledger
http://traffic.libsyn.com/sedaily/2018_02_07_MattLeising.mp3Podcast: Play in new window | Download Your friends from college are asking you how to buy Bitcoin. Your mom is emailing you articles about the benefits of decentralized peer-to-peer networks. Your shoe shiner is telling you to buy XRP. It is 2018, and cryptocurrencies have become a daily part of news headlines. The general public may not understand how this technology works, but everyone knows that changes are on
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
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
http://traffic.libsyn.com/sedaily/BlocksizeDebate.mp3Podcast: Play in new window | Download Visa processes 1,600 transactions per second. PayPal processes 193 transactions per second. Bitcoin processes only 3-4 transactions per second. In order to fulfill the dreams of financial programming–in order to get decentralized, peer-to-peer micropayments–Bitcoin needs a much higher transaction throughput. Bitcoin’s scalability issues have led to debates within the community and changes in the software. In this episode, Jordan Clifford gives an overview
http://traffic.libsyn.com/sedaily/CoinbaseSecurity.mp3Podcast: Play in new window | Download At Coinbase, security is more important than anything else. Coinbase is a company that allows for storage and exchange of cryptocurrencies. Protecting banking infrastructure is difficult, but in some ways the stakes are higher with Coinbase, because bitcoin is fundamentally unregulated. If a hacker were able to syphon all of the money out of Coinbase accounts, Coinbase would have no recourse–which means this
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
http://traffic.libsyn.com/sedaily/blockchainapps.mp3Podcast: Play in new window | Download Cryptocurrencies are not only a financial instrument–they are a new platform for building applications. The blockchain allows for new solutions to digital property management, micropayments, hedge fund incentives, and ad fraud. The cryptocurrency platforms with the most traction are Bitcoin and Ethereum. Bitcoin has no central leader and is going through some growing pains with governance issues. Ethereum is led by the charismatic
http://traffic.libsyn.com/sedaily/coincenter_edited.mp3Podcast: Play in new window | Download Blockchain technologies like Bitcoin and Ethereum have not impacted the lives of most consumers today. The theoretical breakthroughs that blockchain enables will eventually happen–I will be able to pay 1 cent to a knowledge worker in Africa without having to pay a 5 cent transaction fee. My servers will be able to pay other servers for small compute jobs. We will have decentralized
