getConfirmedBlock

Deprecated: This method is deprecated. Use getBlock instead.

Returns identity and transaction information about a confirmed block in the ledger. This method has been deprecated in favor of getBlock, which provides the same functionality with improved API consistency and support for versioned transactions. Existing integrations should migrate to getBlock as this endpoint may be removed in future validator releases.
