All we hear is Ethereum 2.0…But what is it?


To leverage the operating efficiency of the layer 1 protocol blockchain which currently cannot function more than one transaction per second this new protocol of layer 2 was developed. 

Ethereum Layer 2 is the current ongoing one , these protocols are scaling solutions built on top of the Ethereum blockchain to improve the network’s performance and reduce transaction costs. Layer 2 protocols enable the execution of transactions off the main Ethereum chain while still maintaining the security and decentralization of the blockchain.

There are several Layer 2 solutions currently being developed and used by the Ethereum community. These include:

State channels – State channels enable users to transact directly with each other off-chain, only submitting the final state of the channel to the Ethereum network.

Sidechains – Sidechains are separate blockchains that are connected to the Ethereum main net. They enable users to transact on a faster and cheaper network, and then settle the final state on the main Ethereum chain.

Plasma – Plasma is a Layer 2 solution that creates a network of sidechains, allowing for faster and cheaper transactions. Plasma chains can also be connected to other Plasma chains, further increasing the scalability of the network.

Rollups – Rollups are Layer 2 solutions that bundle multiple transactions into a single transaction on the Ethereum mainnet, reducing gas fees and increasing transaction speed.

In summary , these Layer 2 protocols are essential to the future of Ethereum and other blockchain networks, as they enable the network to scale and meet the demands of a growing user base.

Advantages of layer 2 protocol

There are several advantages of using Layer 2 protocols on the Ethereum network, including:

Scalability: Layer 2 solutions can significantly increase the throughput of the Ethereum network, enabling it to process more transactions per second. This is achieved by moving some of the processing off-chain, which reduces the burden on the main Ethereum network.

Lower Fees: By moving transactions off-chain, Layer 2 solutions can significantly reduce transaction fees. This is because transactions on Layer 2 networks do not require as much computational power as transactions on the main Ethereum chain.

Faster Confirmation Times: Layer 2 solutions can also reduce confirmation times for transactions. This is because transactions on Layer 2 networks can be confirmed much faster than transactions on the main Ethereum chain.

Improved User Experience: Layer 2 protocols can provide a much better user experience for dApps and users, making it easier for them to interact with the Ethereum network.

Increased Privacy: Some Layer 2 protocols, such as state channels, can also provide increased privacy for users by enabling off-chain transactions that are not visible to the public.

Disadvantages of layer 2 protocol

While Layer 2 protocols offer significant advantages, there are also some potential disadvantages to consider. These include:

Centralization: Some Layer 2 solutions, such as sidechains, can introduce centralization to the network. This is because they rely on a small number of validators to confirm transactions, which can be vulnerable to attack or collusion.

Security Risks: Layer 2 solutions also introduce new security risks to the Ethereum network. For example, state channels require users to lock up funds in a smart contract, which could be vulnerable to hacking or exploitation.

Complexity: Implementing Layer 2 solutions can be complex and require significant development work. This could make it more difficult for developers to integrate with the Ethereum network.

Interoperability: Different Layer 2 solutions may not be interoperable with each other, which could create fragmentation in the Ethereum ecosystem.

User Experience: While Layer 2 protocols can improve the user experience for dApps and users, they may also introduce new complexities and challenges. For example, users may need to manage multiple wallets or accounts to interact with different Layer 2 solutions.

Of course these limitations may be vanished with a new invention of a third layer, but for now this is better than the present layer 1 blockchain which we are using.. So let’s see how Ethereum will function efficiently with this layer 2 protocol.
