Intro to Ethereum Dapps

– [Narrator] In this lesson, we’ll learn about buildingdecentralized applications or Dapps.But first, let’s take a minuteto appreciate the difference between Dappsand regular web applications.In traditional web application architecture,there is a Front End client, and a Backend server.The Front End is written using HTML, CSS, JavaScript,and the backend is written in a frameworkof your choice like Rails, Node, or Django.The Front and Backend interact with each otherby sending JSON messages…

How to Build an Ethereum Blockchain Explorer Dapp

How to Build an Ethereum Blockchain Explorer Dapp

– In this lesson, we’re going to builda very simple dapp using the Ethereum blockchainas our backend.We’re going to build a blockchain explorerkind of like Etherscan, but we’re only going to displaythe last 10 blocks on the chain.To do this, we’ll use an opensource frameworkcalled ethers.io to quickly develop and deploy our dapp.Ethers comes with command line tools,which are available as a node moduleand can be installed using npm install…

Decentralized Storage Explained

– In this lesson, we’ll learn about decentralized storageand some services that are available todaylike IPFS and Swarm.You can think of decentralized storage asa peer-to-peer network where memberspool together their disk space to createa shared global memory,kind of like Dropbox, but decentralized.Both IPFS and Swarm are similar in thatthey are open source, decentralized storage solutions,but they differ in implementation and approach.IPFS, which stands for InterPlanetary File System,is a protocol that…

Holochain vs Blockchain

Holochain vs Blockchain

HoloHolochain vs BlockchainSo Holochain has a bunch of advantages over blockchain, for one thingthere’s no bottlenecks at all because you are writing directly to your own local source chain andsharing to a distributed hash table which is a an eventual consistencyapproach so there’s no bottlenecks and being able to do the transaction and share the information.The other thing is really that there’s two core underlying fallacies that mostdistributed computing technologies…
