Introduction to Blockchain, Crypto, Metaverse and Web3: Beyond the Hype
Navigating Web3, Crypto, Metaverse and Blockchain

Foundation - Blockchain and Web 3.0

If you are new to crypto, getting a big picture of why Bitcoin is created, its underlying Blockchain technology, and how it evolves to Ethereum and Smart Contracts will lay an essential foundation for understanding a vast majority of the rest of crypto.

A gentle introduction to Blockchain - from Bitcoin cryptocurrency to Ethereum Smart Contracts
The Bitcoin system creates a decentralized platform that disrupts financial payment. This article introduces why Bitcoin is created, what its underlying blockchain technology is, and how the follow-up Ethereum blockchain with the smart contract could extend the disruption to the real economy.

What is Web 3.0? What is its relationship with Blockchain? We explain the history and the different scopes of the Web3/Web 3.0 concept.

What is Web 3.0, after all?
This article helps you understand what the most important technologies in Web 3.0 are, such as Blockchain, Artificial Intelligence (AI), Internet of Things (IoT), Virtual and Augmented Reality (VR/AR). We illustrate how they are evolving and shaping our next-generation web.

Framework - Metaverse and Crypto

With the base knowledge in blockchain and Web 3.0, you are in a great position to start exploring diverse topics of the crypto ecosystem. The figure below illustrates a simple framework I adapted based on my earlier work in 2018.

Metaverse, Crypto, and Blockchain

The outer triangle consists of the three pillars of blockchain systems (Distributed Consensus, Token Economics, and Smart Contracts). The inner circles show the major crypto applications (DeFi, NFT, DAO). Together, crypto and blockchain form the infrastructure for the Metaverse economy.

A full-fledged Metaverse will also signal the arrival of the Web 3.0 era. In addition to the blockchain and crypto infrastructure, hybrid reality technologies that drive the convergences of the physical and the virtual world is the other key propeller for the Metaverse.

What is the Metaverse and where are we in the journey?
We present the two critical aspects of a matured Metaverse: convergence of the physical and the virtual world, and a self-sustainable social-economic ecosystem. We also explain why 2021 is a milestone year for Metaverse and how crypto and blockchain provide the foundation for the Metaverse economy.

Prominent Crypto Applications - DeFi, NFT and DAO

The three most notable crypto use cases as we enter 2022 are Decentralized Finance (DeFi), Non-Fungible Token (NFT), Decentralized Autonomous Organizations (DAO). You can find an overview for each of them below:

Blockchain in finance - from Initial Coin Offering (ICO) to Decentralized Finance (DeFi)
Financial services use cases have been in the forefront of blockchain applications since Bitcoin was born. We will introduce the two major milestones for blockchain in finance, from the ICO boom in 2017 to the DeFi movement today, and help you understand how they are changing the financial industry.
What is Decentralized Finance (DeFi)
What is NFT and where is it heading?
The year 2021 witnesses the explosion of NFT. In this article, we briefly introduce what NFT is and examine what are the factors behind the success of the top NFT projects. Then we discuss the possible future directions NFTs are heading to.
What is a Non-Fungible Token (NFT)
Is DAO the next big thing in crypto and beyond?
We present a big picture of the DAOs (Decentralized Autonomous Organizations) and explain why they could be a central pillar for future social coordination. We also discuss the process of forming a DAO and the challenges ahead in this space.

Blockchain for the Real Economy

If you wonder whether all the crypto stuff is too detached from everyday life, you may find comfort in how blockchain can be applied in diverse real economy sectors.

Blockchain in the real economy: an overview of use cases and sustainability goals
This article provides a brief overview of potential blockchain usage in major real economy sectors and their relationship to the four pillars of urban sustainability.

Diving Deeper

If you have completed most of the above articles, you already obtained a solid base for more in-depth quests into crypto. We provide some selected topics below for your further enjoyment.

How will blockchain transform the creator economy?
The rapidly expanding communities of creators and fans are fueling a burgeoning creator economy. How will blockchain transform the creator economy? How will these transformations impact the challenges faced by today’s creator economy?

Bridging blockchain and the real world - from Oracle to Hybrid Smart Contracts
Blockchain itself forms a separate digital space. But whether in finance or real economy sectors, a blockchain use case often needs to interact with the external world. How can this be accomplished? We introduce how oracle helps bridge the on-chain and off-chain worlds of blockchain.
How does blockchain communicate with the external world using Oracle?
Web 3.0 will be an Autonomous Spatial Web
We review the existing three-layer architecture for the evolution of the Web and discuss ways it can be expanded to further reflect the entire picture. We then present our adapted architecture for the Autonomous Spatial Web 3.0.

Blockchain in the real economy - use case analysis framework
This article introduces an analysis framework for general blockchain use cases. It looks at the assets the use case is handling, the different parties conducting transactions, and the smart contract, distributed consensus, and crypto token models of the underlying blockchain infrastructure.

Blockchain in the real economy - use case classification methods
This article introduces two classification methods that enable us to analyze blockchain use cases from a cross-sector perspective. One method is based on the blockchain’s role as Improver, Transformer, or Enabler; and the other method is based on the use case’s business model.
