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/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

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

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
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
“Nature, technology, and society ultimately will favor the more efficient, the better working systems.”
Ethereum is a decentralized platform for applications that are guaranteed to run exactly as expected via smart contracts.

http://traffic.libsyn.com/sedaily/melanie_blockchains.mp3Podcast: Play in new window | DownloadBlockchains are the distributed ledger technology underlying bitcoin and other cryptocurrencies. More broadly, a blockchain is a mechanism for updating truth states in distributed network computing, producing consensus trust and serving as a new form of general computational substrate. Melanie Swan is a science and technology innovator and philosopher at the MS Futures Group. She founded the Institute for Blockchain Studies, and is the
Bitcoin Week is the third theme of Software Engineering Daily. “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. From August 10-16, interviews with experts on blockchain, Bitcoin, Ripple, Ethereum, and payments will be featured. Fundamental questions: What technological breakthroughs does Bitcoin
