The term ‘Blockchain’ is no longer novel. Asides from been around for while, it has been embraced by numerous industries and its footprint can be seen even from a distance in various industries including the health, environmental and finance sectors. Cost reduction, removal of middlemen, efficiency increase, transparency and high security are some of the perks of the blockchain technology. There has been an increase in the number of blockchain users and in order to manage this increase and other data, blockchain technology has to be incredibly $$scalable$$. The need for scalability while maintaining a high level of security gave birth to the different layers of the blockchain, each with its own distinct features and uses. The blockchain technology is made up of interwoven layers with each layer built on the previous layer and with its own unique purpose. Having an understanding of these layers is important when it comes to getting a picture of how the entire blockchain system functions. There are four layers of the blockchain technology; Layer 0,Layer 1, Layer 2, Layer 3 and Layer 4. Layer 0Layer -0 BlockchainLayer 0 aims at creating a blockchain network that is not only functional and accessible but also with the ability of interacting with each other. This brings about innovation and helps expand the utility of blockchain based tokens. This layer depends on physical infrastructures like hardware, electricity and internet. The protocols of Layer 0 improves communication within blockchain by allowing different blockchains work together and share resources. This is crucial for transferring data and assets between blockchains that are incompatible. Layer 1Layer -1 BlockchainLayer-1 blockchain can be said to be the foundational framework for a decentralized network. It is a distributed ledger technology that securely records transactions on a public and immutable system. This core structure sustains all other blockchain layers, providing them with the infrastructure for disparate applications and protocols. Layer-1 blockchains are solely responsible for managing the distributed ledger, validating transactions, and safeguarding the network from attacks. A consensus mechanism, such as proof-of-work, proof-of-stake, or delegated proof-of-stake, verifies and records transactions, ensuring ledger integrity and network trust. Leading public blockchains like Bitcoin and Ethereum, along with numerous decentralized applications and protocols, rely on layer-1 blockchain technology.Layer 1 Challenges and their Solutions.Despite the benefits of layer-1, the foundation blockchain network faces pressure. The current proof-of-work consensus mechanism, although prioritizing security, is slow and computationally intensive. This energy-consuming process becomes more burdensome as user numbers increase. Consequently, the layer-1 network experiences congestion, hindering transaction speeds and overall capacity. To address these challenges, Ethereum 2.0 introduced proof-of-stake, a more efficient consensus method validating transactions based on participants' staked assets. Additionally, sharding offers a parallel processing approach, dividing the network's workload into manageable segments. By distributing tasks across multiple nodes, sharding accelerates transaction processing and enhances network capacity.
