List of Layer 1 Blockchains 2024: The foundation of decentralized networks

1. What are Layer 1 Blockchains?

Layer 1 blockchains, often referred to as the base layer or the mainnet, are the core architecture of blockchain networks. They are responsible for the primary functions such as consensus mechanisms, transaction validation, and the overall security of the network. Unlike Layer 2 solutions, which are built on top of Layer 1 to enhance scalability and performance, Layer 1 blockchains operate independently and have their own unique protocols.

2. Key features of Layer 1 Blockchains

Key characteristics of Layer 1 blockchains include:

Decentralization: Layer 1 blockchains aim to distribute control across a wide network of nodes to prevent centralization.
Security: They are designed to resist attacks and ensure the integrity and immutability of the blockchain.
Consensus mechanisms: They employ various methods to achieve consensus among nodes, such as Proof of Work (PoW), Proof of Stake (PoS), and their derivatives.
Scalability solutions: Layer 1 blockchains incorporate techniques like sharding and on-chain upgrades to enhance transaction throughput.
Interoperability: They facilitate communication and interaction with other blockchains.

Now, let's explore some of the most prominent Layer 1 blockchains.

3. List of Layer 1 Blockchains

3.1. Bitcoin (BTC)
