Introduction

In this article, we take an in-depth look at the most commonly used blockchain networks. After a brief overview of blockchain technology, we'll examine each blockchain network in this article. We'll begin with a general introduction to the blockchain networks we're examining, covering their basic statistics, pros and cons, popular applications on the network, and the ecosystem.

What is Blockchain?

Encrypted data blocks containing data composed of blocks are called "Blockchains." They are combined into a chain. The information on each block is stored as immutable records and verified by other stakeholders in the network. Discovered in 2008, these networks enable the creation of cryptocurrencies, smart contracts, and applications. There are thousands of Blockchain networks worldwide, and their number is increasing daily. They are divided into L1 (Layer 1) and L2 (Layer 2).

What is L1 (Layer 1) Blockchain Network?

The main chain (mainnet), which forms the foundation of the blockchain ecosystem, is called Layer 1 (L1). It contains two different consensus mechanisms, called Proof of Work and Proof of Stake. All transactions, including block generation and network security, operate at this layer. Layer 1 networks operate at the protocol level. This means that changing the network's transaction speed, block size, or security model requires a direct update to the chain.

L1 Blockchain networks include Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Cardano (ADA), Avalanche (AVAX), and Internet Computer (ICP). Regarding the characteristics of the L1 Blockchain network, L1 networks have their own native token (coin). They use an independent consensus mechanism. Transactions are recorded directly on the chain, and an advanced database mechanism is provided that allows for transparent information sharing. The blockchain database stores data in interconnected blocks on a chain. Because you cannot delete or modify the chain without network consensus, data is chronologically consistent. These ledgers make data immutable and immutable. This increases security and decentralization in the network but limits scalability. As a result, L1 Blockchain networks are highly efficient for tracking orders, payments, accounts, and other transactions.

What is L2 (Layer 2) Blockchain Network?

Layer 2 (L2) Blockchain networks are auxiliary networks built on L1 networks and aim to address the scalability and speed issues of these networks. L2 Blockchain networks perform transactions off-chain and write the results to Layer 1, both reducing transaction costs and increasing speed.

For example, Layer 2 Blockchain networks include the Polygon (MATIC) network, which provides a scaling solution for the Ethereum network. The Arbitrum (ARB) network is an Ethereum-based Optimistic Rollup network. The Lightning Network is a payment network solution for Bitcoin. L2 Blockchain networks operate on the L1 chain. They process transactions off the main chain and write the results back to the L1 network. L2 networks offer lower transaction fees, higher speed, and largely inherit security from the main chain (L1).

To help you better understand the situation, we've prepared a comparison table for L1 and L2 blockchain networks.

Feature Layer 1 (L1) Layer 2 (L2)
Definition Main blockchain protocol Scaling layer built on L1
Transaction Location On-chain (on-chain) Off-chain (off-chain, then committed to L1)
Examples Bitcoin, Ethereum, Solana Polygon, Arbitrum, Lightning Network
Advantage High security and decentralization High speed and low transaction costs

Introduction

Bitcoin was the first blockchain created in 2009 by an anonymous developer or group of developers nicknamed Satoshi Nakamoto. This network uses the Proof of Work (PoW) consensus mechanism and its primary goal is to provide a decentralized, censorship-resistant digital value transfer system. With a 21 million unit limit, Bitcoin is not only a digital currency but also considered "Digital Gold." Recently, it has been widely adopted as a reserve asset by institutional buyers and governments. The network is extremely robust in terms of security and integrity. High transaction costs and limited transaction capacity cause scalability issues. These issues can be addressed with L2 networks.

Ecosystem

Bitcoin is a Layer 1, or L1, network. The Lightning Network operates as an L2 network, integrated with the Bitcoin network for fast and low-cost payment processing. Ordinals Protocol creates and controls entries for Bitcoin-based NFT systems. Runes defines the fungible token standard on Bitcoin. Stacks (STX) operates as an L2 layer, providing smart contract capabilities to Bitcoin. Liquid Network is an enterprise-focused sidechain.

Pros
