Question

What is a sidechain?

Answer 1

A sidechain is a separate blockchain that is attached to a parent blockchain through a two-way peg, allowing for assets from the main chain to be used in the sidechain and vice versa. This enables additional functionality and scalability while maintaining a connection to the main blockchain.

Answer 2

A sidechain is a separate blockchain that runs in parallel to the main blockchain, allowing for the execution of smart contracts and the processing of transactions off the main blockchain. Sidechains can help improve scalability and provide additional functionality without congesting the main blockchain.
