Parallel Chain

A parallel chain, also known as a sidechain, is a separate blockchain that runs parallel to a main blockchain, and is connected to it through a two-way peg. The main blockchain is often referred to as the "parent" chain, while the parallel chain is referred to as the "sidechain".

The main advantage of a parallel chain is that it allows for greater flexibility and scalability. It allows for the creation of new blockchains that can have different consensus mechanisms, token economics, and governance models, while still being able to interact and transfer value with the main blockchain.

A parallel chain can also be used to offload certain types of transactions or smart contracts from the main chain, which can help to reduce congestion and improve the overall performance of the network.

Parallel chains can be used for various purposes, such as creating new decentralized applications, tokenizing assets, or creating new blockchains with different governance models.

It's important to note that parallel chains can run independently of the main chain, but they are still connected to it and rely on it to secure their transactions. Also, parallel chains may have different levels of security and decentralization, and they may have different rules and requirements to participate in their network, so users should carefully evaluate them before using or participating in them.
