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 being maintained is not purely financial. A currency is a necessary component to maintaining the blockchain’s validity. Over the next month, we will be exploring a variety of blockchain-based technologies. Some interviews will be high-level conversations that assume only a familiarity with cryptocurrencies. Some of them will be deeply technical and assume a strong understanding of Bitcoin and Ethereum. And some episodes, like today’s episode, will be aimed at the developer who is in the process of “going down the rabbit hole.” If you are finding yourself reading about Bitcoin and Ethereum a few hours every day, but you are still struggling to grasp the basics, this episode is for you. It is meant to be a complement to other introductory resources, such as “Mastering Bitcoin,” by Andreas Antonopoulos. Cryptocurrency systems are revolutionary–they will unlock completely new applications in the very near future. It’s If you are trying to understand these decentralized currencies and applications, the best place to start is with Bitcoin. That’s why I was happy to have Daniel Van Flymen back on the show. Daniel was previously on for one of our most popular episodes–” Blockchain Building,” in which he talked about how useful it can be to build a blockchain based system for practice. Today, Daniel discusses the basics of Bitcoin transactions. What happens when you send money? How are transactions represented on the blockchain? How do full nodes and light clients interact with each other? These are difficult topics to discuss purely over audio, so this episode is best listened to as a companion resource for someone who is studying cryptocurrencies. If you are looking for an internship, apply to the Software Engineering Daily internship, at softwaredaily.com/jobs. And if you are looking to recruit engineers, you can post jobs for your company there as well–it’s completely free to post jobs and to apply. We are hoping to find interns to contribute to the Software Daily open source project–and if you want to see what we are building, go to SoftwareDaily.com or check out our apps in the iOS or Android app store. They have all 650 of our episodes, with recommendations, related links, discussions, and more. The post Bitcoin Transactions with Daniel Van Flymen appeared first on Software Engineering Daily.

Bitcoin Transactions with Daniel Van Flymen

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 is the author of the Medium article Learn Blockchains by Building One. In his post, he walks you through how to write the code for a blockchain–just like any other web app. He starts with raw Python code, defines the data structures, and stands up his simple blockchain app on a web server to give a toy example for how nodes in a blockchain communicate. For me, this was a great article to read. I have reported on blockchains for over a year, but had not seen such a clear example with executable, simplified code. Stay tuned at the end of the episode for Jeff Meyerson’s tip about making the most of a new job: brought to you by Indeed Prime. To find all of our coverage of cryptocurrencies, download the Software Engineering Daily app for iOS or Android to hear all of our old episodes. They are easily organized by category, and as you listen, the SE Daily app gets smarter, and recommends you content based on the episodes you are hearing. If you don’t like this episode, you can easily find something more interesting by using the recommendation system. The mobile apps are open sourced at github.com/softwareengineeringdaily. If you are looking for an open source project to hack on, we would love to get your help! We are building a new way to consume software engineering content. We have the Android app, the iOS app, a recommendation system, and a web frontend–and more projects are coming soon. If you have ideas for how software engineering media content should be consumed, or if you are interested in contributing code, check out github.com/softwareengineeringdaily, or join our Slack channel (there’s a link on our website)–or send me an email: jeff@softwareengineeringdaily.com The post Blockchain Building with Daniel van Flymen appeared first on Software Engineering Daily.
