chain_getBlock - Bittensor RPC Method
Retrieve block data by hash on Bittensor. Essential for accessing block headers and extrinsics on the decentralized machine intelligence network built around subnets, TAO staking, and validator-miner coordination.
Retrieves complete block information from Bittensor, including the block header, extrinsics, and justifications.
Why Bittensor? Build on the decentralized machine intelligence network built around subnets, TAO staking, and validator-miner coordination with Yuma Consensus, subnet-based specialization, dual Substrate and EVM surfaces, and onchain incentive coordination.
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 decentralized AI inference, subnet-specific AI models, TAO staking, and cross-subnet AI collaboration
- 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
