• Create your first NFT Marketplace for selling cars in PHP Laravel and web3.js

    If you are into Crypto then chances are you have heard about NFT, especially after the incidents like Beeple sold his art for $69 million dollars or this friendship meme. NFT is usually considered is suitable for arts like pictures only but this is not true. NFT is all about uniqueness, authority, and the transfer of ownership. We are going to use NFT for selling cars. In this post, I will be discussing how to mint ERC721 NFT tokens and then integrate them with new or existing websites. The user who buys a car will pay the amount of the car being bought and the minting fee. I came across…

  • Build Your First Solidity Dapp With Web3.js and MetaMask

    Actually, I had planned another topic in Solidity Series for web3.js but then the post could go off tangent hence I am discussing the basics of web3.js and how to interact with a smart contract. I am going to use the same contract I had created here. Basically, it is the web3.js version of the last post. Unlike other posts about web3.js based frontends that use NodeJs and React, I am not going to use any such thing because it is not required to create the front-end of a decentralized app. You do not even need NodeJS at all. You can use your existing skillsets like PHP/Laravel, Django, Rails, etc…

    How to implement Stellar blockchain on existing ecommerce site

    In the last couple of posts, I had discussed the technical site of implementing Stellar blockchain in Python. Those posts stirred interest among many and I got emails about the implementation of it on existing web applications, especially e-commerce websites. Since the actual purpose got buried in lathe st two posts between the lines of code. So today, I am making an attempt to explain in a language that business people, the site owners or managers could understand. Keep reading!

  • How to create a custom token on Stellar network in Python

    A few months back I made a post about Stellar that how you can use it in your Python applications. In this post, I am going to discuss that how you can create your own custom token, a.k.a, a coin programmatically in Python. Before I get into the code, I’d like to discuss what are tokens and their background, how they are different from Alt-coins and some Stellar network concepts. This post is lengthy so read it when you have ample time to read. What are Tokens? The term token is not new and many of us would have experienced the application of it one way or other. Tokens are…

  • Getting started with Python and IPFS

    In this post I am going to discuss how you can use  decentralized IPFS in your Python apps for storing different kind of data. What is IPFS? From Wikipedia: InterPlanetary File System (IPFS) is a protocol and network designed to create a content-addressable, peer-to-peer method of storing and sharing hypermedia in a distributed file system. IPFS was initially designed by Juan Benet, and is now an open-source project developed with help from the community. In simple it’s Amazon S3 on Blockchain. All of your information is available on decentralized network across nodes thus not only make the system scaleable but reliable as well since data which is fed in it…

  • Develop your first python app integrated with decentralized Stellar network

    In this post I am going to discuss how to create a decentralized blockchain app aka dApp for Stellar Network. I will build a very simple web app, world’s simplest Ecommerce app, called it RocketCommerce where people can buy a single item by paying Lumens(XLM), stellar’s currency. The interface of the app looks like below: Before we get into the development of the application itself, allow me to discuss some background of Blockchain, decentralized apps and Stellar Network itself. What is Blockchain? From Wikipedia: A blockchain, originally block chain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[1][6] Each block typically contains a cryptographic hash of the previous block,[6] a timestamp and transaction data.[7] By design, a…
