Relay Chain: A main chain that provides security to Parachains. Parachains: special blockchains that are connected to the Relay Chain and communicate with each other. Bridges: Bridges to external blockchains like Ethereum and Bitcoin.
Parachains in action
Acala: Polkadot’s DeFi Hub with Stablecoin (aUSD). Moonbeam: EVM-compliant Parachain that enables migration of DApps from Ethereum. Astar: Smart Contracts + EVM + WebAssembly. Phala: Private computing services.

Agile Coretime – a new model in 2024 that replaces the Parachain Auction. Instead of “forever” a Slot, projects rent “Core Time” as needed. It lowers entry and increases flexibility.
Competition
Cosmos (IBC) and LayerZero are competitors in the field of interoperability. In 2025, the range of solutions continues to grow. Read about Avalanche.
