WHAT IS SCALLING ?
Scaling on Ethereum refers to various efforts to increase the capacity of the Ethereum network and enable it to process more transactions per second (TPS). There are two main types of âScallingâ solutions : Layer 1 and Layer 2.
In this case I took the example of Blockchain Layer 1 âETHERIUMâ
Layer 1 Scalling
Layer 1 Scaling involves changing the blockchain protocol (Layer 1) to increase its capacity. An example is Ethereum 2.0, a major upgrade to the Ethereum network that will replace proof-of-work (PoW) with proof-of-stake (PoS). This will enable the network to process transactions faster and with lower (maintenance, operation) costs.
Layer 2 Scalling
Layer 2 Scaling is a solution built on top of the Layer 1 (Ethereum) blockchain to increase its capacity. An example is Rollups technology.
Rollups is a layer 2 technology that enables off-chain transaction processing (leaving no trace on Layer 1 chain explorers like etherscan,binancescan), while still using the benefit the security of layer 1 blockchains and allowing large numbers of transactions to be ârolled upâ into a single transaction to reduce burden on the Ethereum network.
Project Crypto Layer 2 Scalling
Arbitrum is a Layer 2 solution designed to increase Ethereumâs scalability. Arbitrum increases transaction capacity and speed while maintaining the same security as Ethereum. It achieves this by leveraging Rollup technology which allows most of the computing and storage to occur off-chain, while retaining the security provided by the Ethereum network.

Optimism or Optimistic Ethereum is a Layer 2 solution for Ethereum which aims to increase scalability and reduce gas costs on Ethereum. The way to achieve this is to use Optimistic Rollup, which is a type of Layer 2 construction. With Optimistic Rollup, transactions are processed and executed outside of Ethereumâs main Layer 1 blockchain (off-chain), and only the final results are posted back to Ethereum. This allows more transactions to be processed in less time, at a much lower cost. But you can track the transcation in this Layer 2 explorer optimistics.etherscan
