Ethereum 2.0: What It Is and How It Will Change the Network

by Sonal Shukla

As the world of blockchain continues to evolve, the Ethereumnetwork has announced a major upgrade that has been in the works for several years. Ethereum 2.0, also known as Eth2 or Serenity, is a significant upgrade that aims to address the scalability, security, and sustainability issues faced by the current Ethereum network. In this article, we will dive deep into what Ethereum 2.0 is and how it will change the network. You can go for crypto trading and investment by logging into The Tesler App

Understanding Ethereum 2.0

To understand Ethereum 2.0, we need to first understand the current Ethereum network. Ethereum is a decentralized platform that enables developers to build decentralized applications (Dapps) using smart contracts. These smart contracts are self-executing contracts that are coded on the blockchain and automatically execute when certain conditions are met.

However, the current Ethereum network is facing several challenges, mainly scalability, security, and sustainability. The current network can only handle around 15 transactions per second, which is significantly lower than other payment networks such as Visa, which can handle thousands of transactions per second. Additionally, the current network is prone to congestion and high gas fees, making it expensive for users to interact with Dapps.

Ethereum 2.0 aims to solve these issues by introducing several new features, including Proof of Stake (PoS), sharding, and a new virtual machine called eWASM.

Proof of Stake (PoS)

One of the biggest changes in Ethereum 2.0 is the switch from Proof of Work (PoW) to Proof of Stake (PoS) consensus mechanism. PoW requires miners to solve complex mathematical problems to validate transactions and add new blocks to the blockchain. This process requires significant computational power and consumes a lot of energy.

On the other hand, PoS is a more energy-efficient and sustainable mechanism that requires validators to hold a certain amount of Ethereum as a stake to participate in the network. Validators are selected to create new blocks based on their stake, and they are incentivized to act in the best interest of the network. This reduces the energy consumption and increases the security of the network.


Another key feature of Ethereum 2.0 is sharding, which is a scaling solution that enables the network to process more transactions in parallel. Sharding divides the network into smaller groups of nodes called shards, each of which can process transactions independently. This increases the network’s capacity to process transactions and reduces congestion and gas fees.


Ethereum 2.0 also introduces a new virtual machine called eWASM, which is a more efficient and scalable version of the current Ethereum Virtual Machine (EVM). eWASM is designed to execute smart contracts faster and with less gas consumption, making it more cost-effective for users to interact with Dapps.

Benefits of Ethereum 2.0

Ethereum 2.0 brings several benefits to the network, including:

Increased scalability: With sharding and other improvements, Ethereum 2.0 can handle significantly more transactions per second than the current network.
Improved security: Proof of Stake is a more secure and sustainable consensus mechanism than Proof of Work, reducing the risk of 51% attacks.
Lower gas fees: With the increased capacity and efficiency of the network, gas fees are expected to decrease, making it more cost-effective for users to interact with Dapps.
Improved developer experience: With eWASM, developers can write smart contracts in a more familiar programming language, increasing the accessibility and ease of use of the platform.


In conclusion, Ethereum 2.0 is a significant upgrade that seeks to address the scalability, security, and sustainability issues that the current Ethereum network faces. With the introduction of Proof of Stake and sharding, Ethereum 2.0 can handle more transactions per second, reduce gas fees, and improve the overall user experience. The transition to Ethereum 2.0 is expected to be gradual, with the first phase already launched in December 2020, and the community is working on mitigating the risks associated with the transition.

Despite the challenges associated with the transition, Ethereum2.0 has the potential to significantly improve the scalability, security, and sustainability of the Ethereum network. The Ethereum community is working on improving education and awareness around the transition to ensure that users are well-informed and can make informed decisions. As the blockchainindustry continues to evolve, Ethereum 2.0 will play a crucial role in shaping the future of decentralized applications and the blockchain ecosystem as a whole.
