 - **`network_config.peer_key`**: Specifies the keyring service's P2P identity information. If not filled, it will be generated randomly.
 
-- **`key_server_config.version`**: The version number necessary for keyring service registration is a collaborative effort between BOOLNetwork official and the community. It increments as the functionality of the keyring software is enhanced or altered. Users should refrain from making arbitrary changes, as it may lead to software malfunctions. The exact software version number and registration version can be obtained from official information.
-
 - **`key_server_config.attestation_style`**: The mode of SGX remote attestation for the keyring service, where `1` represents `EPID` and `2` represents `DCAP`.
 
 - **`key_server_config.seal_policy`**: The data encryption method for the keyring service, supporting `MRSIGNER` and `MRENCLAVE`. It has the same meaning as [Intel SGX sealing](https://www.intel.com/content/www/us/en/developer/articles/technical/introduction-to-intel-sgx-sealing.html). `MRSIGNER` trusts the software publisher, and the advantage is that it is compatible with historical data after software upgrades. `MRENCLAVE` only trusts the code, and the disadvantage is that it cannot read historical data after software upgrades.
