Fractional NFT is a feasible technique to represent the co-ownership of properties. The second part of this series of articles describes how fractional owners are ensured of their rights to their shares of the property when the NFT is transferred to a new owner.

Fractional NFT is a feasible technique to represent the co-ownership of properties. This article demonstrates how the combined use of ERC721 and ERC20 tokens may do so.

A Decentralized App for minting, viewing, and transferring ownerships of NFT-based Certificates of Authenticity for Luxury Watches. In this part, I will walk through the codes to store pin NFT's metadata and photo to IPFS using Pinata.

In the third part of the Freelancer Smart Contract series, I will walk through the Solidity codes beyond the Freelancer Smart Contract.

How does one trade Non-Fungible Tokens (NFTs) or a physical asset that comes with an NFT-based certificate and ensures payment and delivery? This article proposes how a Smart Contract can make peer-to-peer trading of NFTs or physical goods such as luxury watches safe and secure.

Paper-based Certificates of Authenticity for Watches are great candidates to be replaced with Non-Fungible Tokens (NFTs). In this article, I demonstrate how a Decentralized App on the Ethereum Blockchain will allow the creation and transference of NFT-based Watch certificates.

In the 2nd part of this tutorial series, I will demonstrate how to build and deploy my Ethereum-based Freelancer Decentralized App.

In the 1st part of this tutorial series, I will walk through the tools that I use in my Ethereum development environment and demonstrate how to use them to compile and deployed a Solidity Smart Contract.

Luxury products such as watches, diamonds, and bags ship with Certificates of Authenticity that have traditionally been printed on paper. In this article, I demonstrate how it may be possible to replace paper-based certs with Non-Fungible Tokens (NFTs) on the Ethereum Blockchain.

In the second part of the Freelancer Smart Contract series, I will walk through the Decentralized Application that lets the programmer and his client arrange payments, pay, and get paid in ETHs.

Freelancers often need to negotiate with clients on progressive payments and monitoring them while working on the project. In this article, I explain how it may be possible to manage this process using an Ethereum Smart Contract.

My implementation of a Ethereum Faucet on the Ropsten Testnet. In this fourth part, I explain how the Faucet Web App works.

My implementation of a Ethereum Faucet on the Ropsten Testnet. In this third part, I explain how the JSON Web Service that gives out the free ETH works.

A demonstration of a Blockchain-based Voting system in this 3rd out of 5 articles to explore the development of an end-to-end Balloting system on Ethereum.

A walk-through of the voting system's Smart Contract in this 2nd out of 5 articles to explore the development of an end-to-end Balloting system on Ethereum.

This is the 1st of a 5 part tutorial on developing an end-to-end Balloting system on Ethereum. In this part, I demonstrate how voting works on the Blockchain.

In this tutorial, we will walk through the process of building a React Native-based minimum viable Ethereum Mobile Wallet that also runs a smart contract.

A tutorial to run Remix IDE on a cloud server via an external IP address with a username and password

This is the first of a 2-part article that explains the codes behind Smart Contract Explained by Demonstration. This article explains how the seller Dapp works.

This step-by-step guide explains what Smart Contract does by walking you through a real example that you can try.

A demonstration of a Dapp that stores a file on IPFS and referenced in a Solidity Smart Contract on the Ethereum Blockchain.

An emit in Solidity triggers an event. This is a tutorial of how you emit an event in Solidity and watch for it in a DApp.

The underscores _; that are found littered in Smart Contract source codes have invited questions from developers all over who are just beginning to code Smart Contracts. Here, I attempt to demystify it.

Using Safe Remote Purchase as an example, I illustrate how a Smart Contract can execute and manage multiple Smart Contracts at different addresses.

Infura is a convenient tool for Smart Contract developers who do not want to run their own nodes. This is a process of using Infura to deploy a Smart Contract on the Ethereum Blockchain.

This is the final part of the Lottery Smart Contract series whereI will be walking through the codes of the Lottery Smart Contract to explain what some of the more important lines of codes do. 

I built a Sigfox button that when pressed, sends a message to my mobile phone to tell me that its been pressed.

For a few years, I have dreamt of building my own arcade console. It has remained a dream because where I live, there's no space to build nor store one. So I built a handheld one instead.

I wish to build a Bluetooth-based pulse sensor. Imagine a Fitbit that takes your pulse rate as you exercise and send this data real-time to your mobile phone.

With the Go Dutch Smart Contract, bill splitting on supper dates now becomes immutable
