state_getStorage

Returns a storage entry at a specific key on Bittensor.

Why Bittensor? Build on the decentralized AI network with $3.9B+ market cap powering 80+ AI subnets with Yuma Consensus for AI model evaluation, subnet-based specialization, dual Substrate+EVM support, and incentivized AI compute marketplace.

Use Cases

• State queries - Read on-chain storage values
• Account balances - Query account data for decentralized AI inference, subnet-specific AI models, TAO staking, and cross-subnet AI collaboration
• Pallet storage - Access runtime storage items
• Historical state - Query state at specific blocks

Parameters

Parameter	Type	Required	Description
key	String	Yes	Storage key (hex-encoded)
blockHash	String	No	Block hash for historical query
