blob.GetCommitmentProof RPC

Parameters

height

integer

REQUIRED

Specifies the block height from which to retrieve the blob

namespace

string

REQUIRED

Identifies the namespace of the blob within the block

commitment

string

REQUIRED

A base64-encoded hash value that serves as a cryptographic commitment to the blob data, ensuring its integrity

Returns

result

object

The result object which contains the following fields:

subtree_roots

array

An array of base64-encoded strings representing the roots of subtrees within the Merkle tree. Each root is a cryptographic representation of the data in that subtree

subtree_root_proofs

array

An array of proof objects related to the subtree roots

start

integer

The starting index of the subtree root within the data structure

end

integer

The ending index of the subtree root within the data structure

nodes

string

An array of base64-encoded strings representing intermediary nodes within the Merkle proof path for this subtree

is_max_namespace_ignored

boolean

A boolean indicating whether the maximum namespace is ignored in this proof

namespace_id

string

A base64-encoded string that uniquely identifies the namespace for this blob or data group, linking it to its specific domain or category

row_proof

object

The row_proof object which contains the following fields:

row_roots

array

An array of base64-encoded strings representing root hashes for each row in the data structure

proofs

array

An array containing individual proof objects for the row

total

integer

An integer representing the total number of leaves in the row being proven

index

integer

The index of the specific leaf being proven within the row

leaf_hash

string

A base64-encoded hash of the specific leaf node being proven

aunts

string

An array of base64-encoded hashes representing sibling nodes in the Merkle path, used to reconstruct and verify the row's root hash

start_row

integer

The starting row index for this proof within the data structure

end_row

integer

The ending row index for this proof within the data structure

namespace_version

integer

An integer indicating the version of the namespace used, allowing backward compatibility with older namespace versions
