chain_getBlock - Manta Atlantic RPC Method
Retrieve block data by hash on Manta Atlantic. Essential for accessing block headers and extrinsics on the ZK Layer 1 on Polkadot enabling private transactions and on-chain compliance identities.
Retrieves complete block information from Manta Atlantic, including the block header, extrinsics, and justifications.
Why Manta Atlantic? Build on the ZK Layer 1 on Polkadot enabling private transactions and on-chain compliance identities with zkSNARK-powered privacy, modular compliance identities, MANTA token staking hub, and end-to-end transaction privacy.
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 private asset transfers, zkNFTs, on-chain compliance identities, and private parachain asset swaps
- 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
