Ethereum is the most popular platform for smart contracts and decentralized applications (dapps), but it also has its limitations. One of them is scalability, that is, the ability to process a large number of transactions per second (TPS) with low costs and high security. Currently, Ethereum can process around 15 TPS, which is insufficient for the growing demand and competition in the market.

To solve this problem, many have developed different solutions for scaling the Ethereum network, which can be divided into two categories: layer 1 and layer 2. Layer 1 solutions are those that change the very architecture of the Ethereum network, such as Ethereum 2.0,  (PoS ) consensus mechanism and sharding. Layer 2 solutions are those that are built on top of the existing Ethereum network, such as plasma, state channels, optimistic rollups and zk rollups.

In this blog post, we will focus on one of the newest and most innovative layer 2 solutions for scaling the Ethereum network, which is called the Linea Network. Linea Network is a zkEVM network, which means it uses zero-knowledge proofs (ZKP) to verify transactions on the Ethereum Virtual Machine (EVM). CPCs are cryptographic techniques that make it possible to prove that a statement is true, without revealing any additional information. For example, you can prove that you are over 18 without revealing your exact date of birth.

Linea Network is one of the first networks to implement zkEVM, which gives it several advantages over other layer 2 solutions. Some of them are:

• Compatibility. Linea Network is fully Ethereum compatible, meaning it supports all Ethereum smart contracts and dapps, without the need for any code changes. This makes migration and integration easier for developers and users.
• Performance. Linea Network can achieve up to 3000 TPS on a single network, with an average transaction confirmation time of 10 seconds. It is significantly faster and cheaper than the Ethereum network, which has an average confirmation time of 15 minutes and high gas costs. Linea Network also plans to increase its throughput and reduce its confirmation time through interoperability with other zkEVM networks, such as ZKSwap and zkTube.
• Security. The Linea Network is as secure as the Ethereum network, because it uses the same consensus mechanism, proof-of-work (PoW). This means that the Linea Network is resistant to attacks and manipulations, as an attacker would have to have more than 50% of the computing power of the Ethereum network to succeed. Linea Network also uses ZKP to prove the correctness of transactions, which eliminates the need to trust any third party or intermediary.

Conclusion

Linea Network is one of the most promising solutions for scaling the Ethereum network, offering compatibility, performance and security at a high level. Linea Network is still in the early stages of development, but it already has some very interesting projects and I would say that it plays the role of a favorite.
