Sean Han15 Hey Product Hunt! I built Blockchain Demo 2.0 because the original could be more comprehensive! 2.0 will cover topics more in-depth topics such as the P2P network, immutability, mutation, and others! The P2P network is now built-in so you have full control of the network. Also, code snippets are introduced for fellow tinkerers out there! The full source code is here: https://github.com/seanseany/blockchain. I found that blockchain resources rarely go beyond the “revolutionary”, “immutable”, and “distributed” dialogue. To learn how blockchain worked, I resorted to source code and PhD papers, so that you don't have to! I built this because I wish I had a resource like this when I started out. The goal is for everyone to understand blockchain technology in a concise, delightful, and interactive way. If a blockchain revolution is to happen, people need to know how it works! Hope you enjoy the app. - Sean
Saif Al Falah2 @seanhan You write that you had to go through the source code and PhD papers. May I know which papers did you go through?
Sean Han4 @saifalfalah Sure! This one helped a lot! https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2874598
Carlos Ons0 @seanjameshan thank you so much.It is an amazing demo!!! I am starting with blockchain and helps a lot.
Sourabh Shankar2 This version is much more polished than v1 Keep up the good work.
Sean Han2 @sourabh_shankar Thank you!!!
Paul Foley2 Awesome Sean! I look forward to see what you post next.
Sean Han3 @paulfoleytweets Thanks Paul! Your support means a lot! Looking forward to seeing you again!
Sven van der Zee5 A great way to explain the blockchain to people. Thank you!
Sean Han2 @svenvd_zee Thank you! Means a lot!
Tom Whatley3 Despite how much it gives you all at once, I found this super educational the first time around, and have learned even more in the new version. Nice wok @seanhan!
Sean Han2 @thetomwhatley Thanks!! Glad it was helpful!!
Alex Badalyan2 As always, you killed it Sean! Great job!
Sean Han2 @alexbadalyan Thanks Alex! Your support means a lot!
Joost Moerenburg2 Amazing work! Thank you for sharing.
Sean Han2 @j00st Thank you!
𝔏aurent 𝔇el ℜey2 👌
Sean Han2 @ldesserrey 🙏
Abiodun Adetona2 Excellent demo. Well done @seanhan!
Sean Han1 @adetona77 thanks!
Farooq A Rahim1 Wow... Awesome Job...!
Vladimir Filipović1 "Wait, why is one of my cores hammered while looking at this site? Looks like some sho… OHHHHHH I get it!" :)
zavrito0 very cool, interesting and useful application
Chiraag0 This method of learning via interaction makes everything much more fun. Really enjoyed this and hope to see more. Thanks Sean.
Antoniovdw1 This is really helpful for people in the crypto community that want to understand a bit more. The user experience is great, more tutorials should be like this. Definitely listing this in our recommendations list soon :)
Jeisson Lasso Vargas0 Super helpful, congratulations!!
Saif Al Falah5 <p>When I was first starting out with learning about Blockchain the version 1.0 helped me a lot in visualising what it looked like. The version 2.0 improves upon it a lot. I recommed it to everyone new to Blockchains.</p> Pros: <p>1. The interface is slick.</p><p>2. The demos are great.</p><p>3. It includes code so you can peak under the hood and see what's happening.</p> Cons: <p>For the very beginners, introducing so many new concepts at one time, might be a overwhelming. So I'd suggest graduating from 1.0 first.</p>
Sean Han0 Thanks for the constructive feedback!
Prakhar Bhardwaj9 <p>IMHO this is the best learning resource I've come across till now on blockchain technology. Everywhere else you have white papers and powerpoint videos with voiceovers pasted across internet, which are okay to follow, but hard to share with people who do not have enough time to consume them. I'm definitely going to share this with anyone who asks me about blockchain next time.</p><p></p><p>👍</p> Pros: <p>Amazing & descriptive walkthrough</p><p></p><p>Nice UI, which is easy on the eyes</p><p></p><p>The code examples are simple and help understand the concept fast</p> Cons: <p>The current application like UI limits the purpose of demonstrating a concept, in comparison to say a diagrammatic user interface</p>
Sean Han1 Thanks for writing this review!
Brent Heeringa1 <p>A pedantic reader might object to the HASH properties on card (7):</p><p></p><p>1. Different data results in different hash -- while this is true in practice it's not guaranteed as Hash functions are, by definition, many-to-one.</p><p>2. Hash cannot be converted back to data -- this is an open theoretical question.</p> Pros: <p>1. Simple description that captures the essence of block chain</p><p>2. UI was fresh</p><p>3. Toggle code fragments was nice</p> Cons: <p>1. UX sometimes felt unnatural </p><p>2. Description of Hash will make pedants uneasy</p>
Sean Han2 Thanks for the review! 1. Do you have any suggestions to improve the UX? 😊 2. Pushed the following fix: a. Different data results in different hash => Different data results to different hash practically b. Hash cannot be converted back to data => Infeasible to convert hash back to data
Ethan0 <p>Cut through the hype and learn what the blockchain is! It will be 15-30mins well spent.</p> Pros: <p>Demystifies blockchain. Very easy to understand, doesn't require any technical knowledge. Also looks beautiful 😍.</p> Cons: <p>None that I can think of</p>
Guillaume Torche0 <p>Blockchain Demo explains a complex technology in a user friendly way through a well thought set of steps. It's a nice online resource to direct your non technical friends if they want to understand the basics of blockchain. </p> Pros: <p>Super ingenious and user friendly way to understand the basics of blockchain.</p> Cons: <p>No cons</p>
