Parachains are a type of blockchain technology built on top of a shared infrastructure or mainchain.
The mainchain provides a backbone for these parachains to function and acts as a secure, centralized platform for transactions and data storage.
Each parachain is a separate, independent blockchain operating on the main chain. They have their unique features and functions but still rely on the mainchain for security and interchain communication.
This allows for more scalability and efficiency compared to traditional blockchains, as multiple transactions can occur simultaneously on different parachains without interfering with each other.
Parachains can be used for various applications, such as decentralized finance (DeFi), gaming, and data storage. They also provide a more efficient solution for tokenizing assets and creating decentralized exchanges (DEXs).
