What Is a Layer-1 Blockchain?

When it comes to blockchain technology, there are two main types of layers: layer 1 and layer 2. These layers work together to create a decentralized digital ledger, which functions as a peer-to-peer and immutable public database. In this article, we will focus on layer-1 blockchain technology, which serves as the foundation for the entire blockchain network.

The purpose of layer-1 blockchain technology is to provide a secure, immutable, and trustless ledger that records transactions. It is the most basic form of blockchain technology and is responsible for maintaining the distributed ledger, validating transactions, and securing the network against malicious actors. Without layer-1 blockchain technology, it would be impossible for other applications and protocols to function effectively.

A key feature of layer-1 blockchain technology is the consensus mechanism used to validate and record transactions. Common consensus mechanisms include proof-of-work (PoW), proof-of-stake (PoS), and delegated proof-of-stake (DPoS). These mechanisms ensure that the ledger is immutable and can be trusted by all network participants.

Bitcoin and Ethereum are two examples of layer-1 blockchain networks. Bitcoin is a digital currency and payment system that operates in a decentralized manner, while Ethereum is an open-source public blockchain platform designed for building and deploying decentralized applications and smart contracts. Both of these networks rely on layer-1 blockchain technology as their foundation.

In contrast, layer-2 blockchains are designed as a scaling solution for layer-1 blockchains. These blockchains enhance scalability and efficiency and often rely on the underlying layer-1 blockchain as a foundation. By leveraging the capabilities of the layer-1 blockchain, layer-2 blockchains offer a practical solution to address the challenges associated with scalability.

In conclusion, layer-1 blockchain technology serves as the foundation for the entire blockchain network. Its purpose is to provide a secure, immutable, and trustless ledger that records transactions. With the ability to validate and record transactions and maintain the distributed ledger, layer-1 blockchain technology is a critical component of the blockchain ecosystem.
