Parachain

Parachain is a shortened form from “parallel chain”. It is an additional parallel chain (chain) that works alongside the primary blockchain.
Polkadot and Kusama:
Parachains are often associated with the Polkadot and Kusama ecosystem. Polkadot is a multichain platform, and Kusama is its test network. Both projects were created by Dr. Gavin Wood, co-founder of Ethereum.
Layer 1 in the Multichain Ecosystem:
Parachains are considered Layer 1 in the multichain ecosystem, meaning that they operate directly at the level of the original blockchain, rather than being built as smart contracts on a layer above, as is the case with some other platforms.
Bridges and Relay Chains:
In Polkadot and Kusama networks, parachains are connected to the relay chain via bridges. The relay chain acts as the main chain, managing the consensus and security of the entire network.
Slot allocation:
Slot allocation (slot allocation) is the process by which parachains gain access to limited space on the main chain. Each slot is assigned for a specific period of time, allowing different parachains to use the main chain at specific intervals.
Sharing Security:
In the Polkadot and Kusama ecosystem, parachains share security with the relay chain, meaning they benefit from the computing power and security of the entire network.
Multilateral Interactions:
Unlike some other blockchains, where smart contracts operate on a single chain, parachains allow for multi-party interactions, which allows for more complex and extensive interchain interactions.
Flexibility and Scalability:
The concept of parachains increases the flexibility and scalability of the blockchain ecosystem, allowing multiple parallel chains to operate simultaneously.
Innovation and Specialization:
Each parachain can be designed with specific applications or innovations in mind, allowing for the development of different functions and services within the Polkadot and Kusama ecosystem.
Parachains are an important part of the development of the blockchain ecosystem, offering flexibility, scalability and the ability to collaborate between different parallel chains. Projects using this technology can adapt to different needs and applications, creating more advanced and diverse blockchain ecosystems.
