Field	Type	Description
last_processed_evm_block	int	Last processed EVM block (scan for new checkpoints)
last_processed_zcash_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)
indexer_synced	boolean	Whether the latest SMT Root of the synced checkpoints of the Indexer is equal to the latest processed SMT Root by the Indexer. This doesn't mean that the node is fully synced. Always check latest validated root from the EVM contract to determine the full sync state.
domains_count	int	Total names registered
registrar_address	string	Address of the Registrar to process incoming TXes and escrow
registrar_viewing_key	string	Viewing key of the Registrar ZCash Address to get an access to Protocol history
last_checkpoint		Latest checkpoint information (latest SMT Root update)
smt_root	string	Latest Merkle tree root (hex)
block_id	int	ZCash block_id of the last checkpoint and SMT Root generation
evm_block_id	int	EVM block_id where last Proof is checked with SP1 smart contract
evm_tx_hash	string	EVM tx_hash where last Proof was checked with SP1 smart contract

warning

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