eth_getBlockByHash - Bittensor RPC Method
Retrieve complete block data by block hash on Bittensor. Essential for AI/ML developers, subnet operators, and teams building decentralized machine learning applications building on the decentralized machine intelligence network built around subnets, TAO staking, and validator-miner coordination.
Returns information about a block by hash on Bittensor.
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 eth_getBlockByHash method is essential for:
- Block verification - Verify block data using its unique hash
- Chain reorganization handling - Track blocks during reorgs
- Cross-chain bridges - Verify block finality for decentralized AI inference, subnet-specific AI models, TAO staking, and cross-subnet AI collaboration
- Deterministic queries - Get consistent block data regardless of chain state
Code Examples
Error Handling
| Error Code | Message | Description |
|---|---|---|
| -32602 | Invalid params | Invalid block hash format |
| -32000 | Block not found | Block with this hash does not exist |
