storeBatchInAnchor

Stores a summary hash (typically a Merkle root, batchRoot) representing a large batch of commitments or data into the Anchor program. This is used for efficiently managing large, potentially periodic, datasets.

It's similar to storeMerkleRootInAnchor but often includes additional identifiers like batchId to distinguish different batches (e.g., "weekly data batch").

Parameters

Parameter	Type	Description
privateKeyBase58	const String&	The private key of the account's authority.
authorityPubkey	const String&	The public key of the authority.
programId	const String&	The ID of the Anchor program to interact with.
batchId	const String&	A unique identifier for this batch of data (e.g., "batch_10102025").
batchRoot	const String&	The Merkle root hash representing the entire batch.
batchSize	uint32_t	The total number of data items (commitments) included in this batch.
metadata	const String&	Metadata string to store alongside the batch root.
outTxSignature	String&	Output: If successful, the signature of the transaction.

Return Value

• bool: Returns true if the batch data was stored successfully.
