Side Chain

November 21, 2023 - Around 3 mins mins to read

Side chains are an integral component of blockchain technology that enable the creation of secondary blockchains linked to the main chain through a two-way peg. This peg allows for seamless transfer of tokens and digital assets between the main chain and the side chain, enhancing the overall functionality and scalability of the blockchain network.

To understand side chains better, imagine a decentralized network comprised of multiple independent blockchains, each serving specific purposes and enforcing unique rules. These blockchains, known as side chains, are interconnected, forming a cohesive ecosystem that offers various benefits to users and developers.

One prominent example of a side chain is the Liquid Network. It acts as a settlement layer for traders and trading platforms, facilitating faster and more private transactions compared to the main chain, Bitcoin, to which it is pegged. The Liquid Network also enables the creation of new digital assets, expanding the range of possibilities within the blockchain ecosystem.

The process of utilizing a side chain involves transferring coins or digital assets from the main chain to a specific output address, where they become locked and unspendable in other locations. Once the transaction is confirmed and a waiting period has passed to ensure security, the coins or assets are fully transferred to the side chain. This allows users to freely move and interact with them within the new network. If needed, the coins can be sent back to the main chain by reversing the process.

Side chains can serve different functions and purposes. For instance, both Liquid and Rootstock are side chains of Bitcoin; however, they have distinct roles within the ecosystem. Liquid primarily focuses on facilitating faster transactions and serving as a settlement layer, while Rootstock is specifically designed to execute smart contracts efficiently on the Bitcoin blockchain.

Ethereum 2.0, a major upgrade to the Ethereum blockchain, introduces its own version of side chains called shard chains. These shard chains are interconnected with the recently launched Beacon Chain, which aims to become the main chain for Ethereum’s proof-of-stake (PoS) consensus mechanism. The introduction of shard chains in Ethereum 2.0 is expected to greatly enhance the scalability and throughput of the Ethereum network, enabling it to handle a larger number of transactions and smart contracts.

The use of side chains provides several advantages to blockchain networks. By offloading certain transactions or computations to side chains, the main chain’s capacity can be preserved for more critical operations, improving overall network efficiency. Side chains also enable the development of specialized functionalities and applications tailored to specific use cases, thereby expanding the capabilities of the blockchain ecosystem.

In summary, side chains are secondary blockchains linked to the main chain through a two-way peg. They enhance the functionality, scalability, and flexibility of blockchain networks by enabling the seamless transfer of tokens and digital assets between different chains. Side chains serve various purposes, from facilitating faster transactions and settlement layers to executing smart contracts efficiently. As blockchain technology continues to evolve, the use of side chains is expected to play a crucial role in expanding the possibilities of decentralized networks.
