In this article, you will learn what is a Layer 1 blockchain. Scalability is the ability of a system to handle increased load or traffic. In the context of blockchains, it is the ability to process more transactions per second (TPS) in order to meet the growing demands of users, something that layer 1 networks really struggle with.
What is Layer 1 Blockchain?
"Layer 1" refers to the underlying protocol layer of a blockchain network, which defines the basic rules and mechanics of the network. In the context of blockchain technology, a "Layer 1" blockchain is a standalone blockchain protocol that operates independently without relying on any other blockchain networks.
Some examples of Layer 1 blockchains include Bitcoin, Ethereum, and Litecoin. These blockchain networks have their own unique consensus mechanisms, programming languages, and other features that differentiate them from each other.
In contrast, "Layer 2" solutions are built on top of existing Layer 1 blockchains and provide additional functionality and scalability to the underlying blockchain network. Examples of Layer 2 solutions include Lightning Network and Plasma, which aim to address the scalingr issues blockchains by allowing for faster and cheaper transactions.
How is Scaling a Problem in Layer 1 Blockchain?
Scaling is a problem in Layer 1 blockchain networks because of their inherent design and architecture. Most Layer 1 blockchains, such as Bitcoin and Ethereum, use a Proof-of-Work (PoW) consensus mechanism, which requires a large number of nodes to perform complex computations to validate transactions and create new blocks. This process is computationally intensive and requires a significant amount of energy to maintain, leading to slower transaction processing times and higher fees.
As more users and applications start using the blockchain network, the number of transactions and data on the blockchain also increases, leading to congestion and longer processing times. This issue is exacerbated by the limited block size and block interval of Layer 1 blockchains, which can only process a certain number of transactions per block and can only generate a new block at set intervals.
To address this issue, Layer 2 scaling solutions, such as sidechains and state channels, have been developed to enable faster and more efficient transactions by reducing the load on the main blockchain. These solutions can process transactions off-chain and only only periodically settle them the main blockchain, allowing for increased scalability and reduced fees.
Bottom Line
The two most obvious examples of a Layer 1 network are Bitcoin and Ethereum. These blockchains are base networks – they handle every aspect of every transaction on-chain and without assistance from any other network. This article is about what is a Layer 1 blockchain.
