A parachain is a specialized blockchain that operates alongside a main network, often referred to as a relay chain. Parachains are designed to leverage the security and scalability provided by the relay chain while allowing their own unique functionalities and governance.Each parachain can have its own consensus mechanism and can focus on specific use cases, such as decentralized finance (DeFi), identity management, or supply chain tracking. This flexibility enables developers to create and optimize applications tailored to their needs.Parachains connect to the relay chain through a process called “parachain slot auctions.” Projects bid for limited slots, which allows them to establish their parachain for a specific period. By sharing the security and resources of the relay chain, parachains can communicate and interact with one another, leading to increased interoperability and efficiency across the network. Overall, parachains enhance the ecosystem by offering diverse functionalities while benefiting from the strength of a central, secure infrastructure.
