This article begins with the basics—simple blockchain concepts and essential terminology. From there, the series delves into how companies, foundations, and tokens are created and organized in this digital asset landscape. We’ll explore the different roles that organizations and entities play, how tokens are issued to interact with these platforms, and the way governance and incentives are designed. Finally, we will break down the ecosystem into the main market segments, exploring the current landscape and the direction each is headed. These segments are then analyzed in detail, focusing on factors like viability, adoption, and how competitors compare, offering a clear understanding of the key players.
The objective of this series is to explain blockchain as simply as possible, using everyday examples and terms that are easy to relate to. This is not intended as a deep dive into the technology; instead, the focus is on avoiding unnecessary complexities. Advanced ideas will be revisited in future articles, but for now, the focus remains on straightforward explanations, ensuring the reader can grasp the basic concepts in a way that makes sense in everyday life. The terms and examples introduced here will be built upon throughout the rest of the series.
Blockchain
To begin, it's essential to understand the underlying technology of digital assets, The Blockchain, which was created to solve the problem of trust and centralization in traditional financial systems.
Traditionally, financial transactions have been recorded using double-entry accounting, a system that dates back to ancient empires, churches, and eventually, modern banks. This method allowed merchants and institutions to track both debits and credits, ensuring accurate records of money owed and money paid. Over time, centralized entities, like banks, adopted this system to maintain financial ledgers, being the single authority responsible for controlling and updating the records.
In centralized systems, trust is placed entirely in this one entity to manage, verify, and secure the ledger. While double-entry accounting revolutionized financial record-keeping, centralizing all power in one institution introduces risks. If the bank’s system is compromised, manipulated, or goes offline, the entire ledger becomes vulnerable, potentially affecting everyone who relies on it.
Blockchain set out to solve this issue by decentralizing the ledger. Instead of having a single organization in charge, a blockchain is like a shared Google spreadsheet that anyone can view, but no one can change without consensus from the entire group. Even more powerful is the permissionless nature of blockchain—anyone can participate in the network without needing approval from a central authority.
Imagine this spreadsheet is continuously updated with transactional data—every time someone makes a transaction, a new entry is added. Unlike traditional systems, where a central authority controls the ledger, this shared spreadsheet is maintained by a network of independent participants, all with equal access to the information. Once a transaction is added, it becomes immutable—meaning it cannot be changed or deleted—ensuring transparency, security, and trust among all participants.
Understanding the Blockchain Layers
Terms like 'Layer 1 Blockchain,' 'Layer 1 Smart Contract Chain,' or 'L2s' are often mentioned but rarely fully explained. To clarify, the Google Sheets analogy can help break down what these layers are, how they interact, and how they differ from each other.
Layer 1: The Foundation of the Blockchain
Layer 1 is the core system where all transactions and data are processed directly. Think of Layer 1 as a public, shared Google spreadsheet that acts as a ledger for financial transactions between a group of participants in a decentralized system. This spreadsheet replaces the need for a traditional bank’s ledger by allowing anyone in the network to record and view transactions in real-time. Because it’s public, every transaction—whether it’s sending money, transferring assets, or recording other financial data—is visible to all participants, ensuring transparency and trust within the system.
The need for such a public ledger arises from the decentralized nature of the system, where no single entity, controls the records. Instead, the entire network collectively verifies and updates the spreadsheet, making it tamper-proof and secure.
However, since all activity occurs on this shared spreadsheet, there are limitations on how many transactions can be processed at once. When too many users attempt to write or update data simultaneously, the system slows down due to limited processing capacity. This creates a bottleneck, where the network can only handle a certain number of transactions at a time. As a result, transactions take longer to process, leading to delays in updating the blockchain.
Bitcoin and Ethereum are examples of Layer 1 blockchains that process all data directly on the network.
Layer 2: Extending the Spreadsheet's Capabilities
Layer 2 is like a separate tool that helps the main spreadsheet work more efficiently. Instead of writing every transaction directly to the Layer 1 spreadsheet, we use this additional tool (Layer 2) to temporarily handle some transactions and only add the final results to the main spreadsheet. This reduces the load on Layer 1, making it faster to manage large amounts of transactions.
Think of Layer 2 as a temporary spreadsheet. You perform many calculations or actions there, and once you’re done, you summarize the results and send just the important updates back to the main shared spreadsheet. The main spreadsheet (Layer 1) still holds the final, authoritative version of the data, but Layer 2 helps manage and process the workload more efficiently.
For example, imagine a public transportation system. When passengers take multiple trips during the day using a transit card, the system doesn’t need to log each trip individually in real-time to the main database. Instead, all trip data is collected on a secondary system (Layer 2), and at the end of the day, the total fare and trip data are uploaded to the main system (Layer 1) for final record-keeping. This reduces the need to frequently update the core system with every single trip.
The Lightning Network for Bitcoin and Optimistic Rollups for Ethereum are examples of Layer 2 solutions.
Layer 3: Interface and Tools for Users
Layer 3 is the user-friendly software that interacts with the shared spreadsheet and its extensions. While Layers 1 and 2 handle the underlying transaction data, Layer 3 is the interface that allows different applications or systems to easily communicate with the blockchain. If you imagine that Layer 1 is the Google spreadsheet and Layer 2 is an extension that makes it faster, then Layer 3 would be like the programs or apps that give people easy ways to access and work with the data.
Instead of interacting directly with the shared spreadsheet, users might use an application that presents the information in a clearer or more helpful way, but underneath, that application is still updating or pulling from the main shared spreadsheet. Layer 3 ties everything together for seamless interaction but relies on the underlying layers to handle the real processing.
A decentralized ride-sharing app is an example of how Layer 3 can provide a seamless, user-friendly interface, allowing users to book rides and pay drivers without realizing they are interacting with blockchain technology. While the app handles the front-end experience, Layer 2 processes payments quickly and efficiently behind the scenes, and Layer 1 securely stores the final ride and payment records, ensuring transparency and security.
Layer 3 provides seamless interaction for users, while relying on the underlying blockchain layers for performance, scalability, and security.
Uniswap, MetaMask, OpenSea, and Axie Infinity are examples of Layer 3 technologies that provide user-friendly interfaces for decentralized finance, digital wallets, NFT trading, and blockchain gaming, respectively.
Key Concepts Simplified
As this section concludes, it's important to revisit a few key terms fundamental to understanding blockchain. First, immutability refers to the fact that once a transaction is added to the blockchain (or the shared Google Sheet), it cannot be changed or deleted, ensuring the data is reliable and tamper-proof. Next, permissionless means that anyone can join the network and participate without needing approval from a central authority, similar to how anyone can access and view the shared sheet. Finally, decentralization indicates that no single entity is in control; instead, power is distributed among all participants, ensuring transparency and fairness, unlike traditional systems where a centralized authority manages the ledger.
In the context of these terms, Layer 1 is the foundational blockchain itself, where all transactions are recorded and secured, ensuring immutability and decentralization. Layer 2 solutions build on this by helping the blockchain scale more efficiently, allowing for faster and cheaper transactions while still relying on the security of Layer 1. Finally, Layer 3 represents the user-facing applications that interact with the blockchain, making it easier for everyday users to access and work with the data stored on Layers 1 and 2.
By understanding these key terms and the different layers, you're better equipped to grasp how blockchain fundamentally differs from traditional systems and why it’s considered such a revolutionary technology.
