chain_getBlock - Bifrost RPC Method
Retrieve block data by hash on Bifrost. Essential for accessing block headers and extrinsics on Polkadot's largest liquid staking appchain with 60% DOT LST market share and $125M+ TVL.
Retrieves complete block information from Bifrost, including the block header, extrinsics, and justifications.
Why Bifrost? Build on Polkadot's largest liquid staking appchain with 60% DOT LST market share and $125M+ TVL with first LST governance on OpenGov, 60% DOT market share, Hyperbridge ETH integration, and 500K DOT treasury support.
Use Cases
The chain_getBlock method is essential for:
- Block explorers - Display complete block information
- Chain analysis - Analyze block production patterns
- Transaction verification - Confirm extrinsic inclusion for omnichain liquid staking (vDOT, vKSM, vGLMR, vMOVR, vASTR), cross-chain vToken governance, and DOT/ETH liquidity bridging
- Data indexing - Build historical blockchain databases
Best Practices
- Cache block data by hash -- blocks are immutable once finalized on Substrate chains
- Use
chain_getBlockHashfirst to resolve block number to hash before calling this method - Handle
nullresults gracefully for non-existent blocks - Combine with
chain_getFinalizedHeadfor consensus-safe block retrieval
