Field	Type	Description
last_processed_coin_block	int	Latest processed block on chain (usually last checkpoint's block_id)
indexer_smt_root	string	The latest point of Indexer's sync (SMT Root of the Indexer)
anchored_smt_root	string	The root the anchor contract currently attests to, read directly from its state
indexer_synced	boolean	Whether this node’s independently computed root equals the root the anchor contract attests to. This is the full sync check — it is measured against the contract, not against a local table
checkpoints_behind	boolean	True when this node’s newest checkpoint is older than the root the contract attests to — i.e. discovery is lagging
domains_count	int	Total names registered
registrar_address	string	Address of the Registrar to process incoming TXes and escrow
registrar_viewing_key	string	Full viewing key of the Registrar ZCash Address, giving access to the whole Protocol history — incoming commands and outgoing payouts alike
last_checkpoint		Latest checkpoint information (latest SMT Root update)
idx	int	Position in the anchor contract’s rootChain array; the resume cursor for checkpoint discovery
smt_root	string	Latest Merkle tree root (hex)
block_id	int	ZCash block_id of the last checkpoint and SMT Root generation

warning

If last_processed_coin_block is significantly behind last_checkpoint.block_id, recent registrations may not be reflected yet.
