If you have ever heard of on chain and off chain, you might also have heard of sidechain. So what is ETH sidechain and The potential of sidechains. If you are not familiar with ETH sidechain, this article is for you.
Does Ethereum have sidechains?
Bridges use smart contracts and sidechains deployed on the Ethereum mainnet to control the bridging of funds between them. While bridges help users transfer funds between Ethereum and sidechains, assets are not physically transferred between the two chains.
What is ETH sidechain?
Sidechains are separate Ethereum-compatible blockchains that employ their own consensus model and block parameters to efficiently process transactions. Public EVM sidechains are designed for interoperability with Ethereum. Contracts are usually portable, and assets and data can be transferred across chains. Public sidechains are useful in many different contexts, including microtransactions, stable transactions, and application-specific transactions (NFT-based art, DAO voting, community currencies, etc.).
Ethereum sidechains are independent blockchain networks that run in parallel with the Ethereum mainchain. Sidechains are connected to the main chain through a two-way peg system, allowing assets to be exchanged between chains.
There are two basic types of sidechains, one where one chain is dependent on another, and one where they are independent of each other. When a chain depends on another chain (such as Ethereum), it can be considered as a child chain of this parent chain. Typically, child chains do not create their own assets, but instead acquire any assets from transfers from the parent chain.
How Do Sidechains work?
Layer 2 sidechains are distributed ledgers that operate independently and in parallel with the Ethereum mainnet. Nodes in the sidechain network are responsible for confirming and processing transactions, writing transactions into blocks, and maintaining consensus across the network. Security is the responsibility of each sidechain; it is not directly inherited from Ethereum. Sidechains often include alternative validator selection and consensus mechanisms to provide faster transaction times.
The potential of sidechains
Sidechains have enormous potential to expand the scope, scale and dynamics of blockchain technology, allowing previously isolated blockchain networks to be integrated into a common ecosystem. From a macro perspective, imagine a general blockchain network consisting of numerous blockchains, each with its own consensus mechanism , governance rules, and vision, but they are all independent of each other.
The ability to move assets and data between chains is an important aspect of the sidechain environment. Applications use sidechains for fast and cheap transactions, but the results of these transactions should be easily transferable across chains. This is sometimes called a two-way peg.
I hope now you will understand what is ETH sidechain and the potential of sidechains. Sidechains have their own consensus protocols, which are usually designed for specific types of transactions, making them faster and more affordable. However, this also means that they generally do not inherit the security properties of Ethereum, and when using sidechains, you lose custody of your funds and rely solely on the sidechain's security, including participating in its own consensus protocol node.
