# gRPC: obtaining node configuration parameters¶

To get the node configuration parameters, the method and request NodeConfig is used. This method is packed in the util_node_info_service.proto protobuf file.

The NodeConfig query does not require any additional parameters. The following configuration parameters for the node that was queried are displayed in the response:

• version - version of the blockchain platform in use;

• crypto_type - cryptographic algorithm in use;

• chain_id - identifying byte of the network;

• consensus - consensus algorithm in use;

• minimum_fee - minimum transaction fee;

• minimum_fee - additional transaction fee;

• max-transactions-in-micro-block - a maximum number of transactions in a microblock;

• min_micro_block_age - minimum time of microblock existence (in seconds);

• micro-block-interval - interval between microblocks (in seconds);

• pos_round info: when using the PoS consensus algorithm, the average_block_delay parameter is displayed (the average block creation delay time, in seconds);

• poa_round_info: when using the PoA consensus algorithm, the parameters round_duration (block mining round length, in seconds) and sync_duration (block mining synchronization period, in seconds) are displayed.
