We can better comprehend the architecture of various blockchains, projects, and development tools by using the terms layer 1 and layer 2. Understanding “What is Layer 1 blockchain?” will be useful if you've ever pondered how Polygon and Ethereum or Polkadot and its parachains are related.
What Is Layer 1 Blockchain?
A basic blockchain is also known as a layer-1 network. Layer-1 systems include BNB Smart Chain (BNB), Ethereum (ETH), Bitcoin (BTC), and Solana. Since these are the primary networks in their ecology, we refer to them as layer 1. We have off-chains and other layer-2 solutions that are constructed on top of the primary chains, in opposition to layer-1 solutions.
In other terms, when a protocol processes and completes transactions on its own blockchain, it is considered layer 1. Additionally, they have a native token that they use to cover trade costs.
The inability of layer-1 networks to scale is a prevalent issue. In periods of increased demand, Bitcoin and other large blockchains have had difficulty processing transactions. The Proof of Work (PoW) consensus method is used by Bitcoin.
Although PoW guarantees decentralization and security, PoW networks also have a tendency to sluggish down when there are too many operations. As a result, fees go up and transaction confirmation periods length.
Although blockchain developers have been focusing on scalability issues for a while, there is still much debate about the best options. Options for layer-1 scaling include:
-Increasing the block size will enable each block to handle more transactions.
- Altering the consensus process, as will be done with the forthcoming Ethereum 2.0 upgrade.
- Putting sharding into action. a technique for dividing databases.
Implementing improvements from Layer 1 takes a lot of effort. It's common for not all network consumers to accept changes. This might result in a hard fork or even group splits.
What Are The 5 Layers Of Blockchain?
Blockchain primarily consists of five layers: the application layer, the network layer, the consensus layer, and the hardware infrastructure layer. Every layer performs a specific purpose. Together, these layers enable user-facing apps on the front end and provide data management on the back end for the blockchain as a whole.
Summary
What is Layer 1 blockchain? It's simple to become confused, but once you understand the fundamental ideas, it gets simpler to comprehend the overall structure and design.
