Native Polkadot Capabilities

Leverage the full power of the Polkadot ecosystem

Shared Security

Leverage the Polkadot relay chainRelay ChainCentral chain of Polkadot that provides shared security and cross-chain messaging. Docs for validatorValidatorNode that validates parachain proofs and secures the relay chain. Docs -backed security without running your own validator set.

XCM Messaging

Native cross-chain interoperability with other parachainsParachainApplication-specific blockchain connected to the relay chain for shared security. Docs through the XCMXCMCross-Consensus Messaging format for communication between chains. Docs protocol.

Smart Contracts

Deploy Solidity smart contracts on Polkadot.

Forkless Upgrades

Upgrade runtimeRuntimeState transition function compiled to WASM that defines chain logic. Docs logic without hard forks through on-chain governance.

Deterministic Finality

6-second block times with guaranteed finality through GRANDPAGRANDPAGHOST-based Recursive ANcestor Deriving Prefix Agreement. Polkadot's finality gadget. Docs .

Async Backing

Increased throughput and reduced latency with asynchronous block validationAsync BackingAsynchronous collation pipeline that increases throughput and reduces latency. Docs .
