NodeRefresher periodically queries the mixnet contract for all bonded nodes and probes each node's HTTP API for host information, sphinx keys, noise keys, and key rotation IDs - Extract NymNodeApiClientRetriever into nym-node-requests with port probing, identity verification, and host information signature checking - Add clone_query_client on NyxdClient so the refresher can hold its own query client without locking the signing client - Batch upsert for nym_node rows (single transaction instead of per-row) - Reuse the new helpers in nym-api's node_describe_cache ensure assignment of testrun begins an IMMEDIATE tx construction of the orchestrator struct initial set of cli args make sure to not assign testable nodes too often very initial database structure and cli fixed construction of RoutableNetworkMonitors remove redundant constructor for NoiseNode forbid 0-nonsense config values add type safety for test route construction moved lioness and arrayref to workspace deps fixed dockerfile build always use canonical addresses in RoutableNetworkMonitors fixed old contract formatting issues removed redundant into() call network monitor agent fixes additional logs config unit tests more docs standalone stress testing invocation further refactoring and changes refactor testing loop and return valid test result upon completion initial sending/receiving test loop generating reusable sphinx headers additional structure for receiving ingress packets initial scaffolding for NMv3 agent added validation of x25519 noise key removed unstable call to 'is_multiple_of' remove calls to from_octets as they're unavailable in pre 1.91 additional docs/comments propagating noise information about NM for mixnet routing pass full socket address of the agent into the contract storage feat: store noise keys alongside ip addresses within the contract removed redundant comment ensure NM packets can only go to NM PR review comments added additional docs allow NM to replay packets + fix replay prometheus metrics propagate information about nm agent to connection handler updated nym-node config migration feat: introduced nym-node websocket subscription for keeping updated list of NM agents allow admin to also revoke monitor agents remove agents upon orchestrator removal fixed schema generation and regenerated the contract schema removed rustc restriction on contracts-common added client methods for interacting with the contract added unit tests for contract methods implemented logic of the network monitors contract create initial structure for network monitors contract start mix stress testing topic branch * make nym-node default to the new blockstream rpc/ws node cluster * reduced mixnet-client log severity * set network monitors contract address for mainnet
Nym API
The Nym API provides multiple services to the Nym network, and is designed to be run alongside Nyxd validators. From a logical perspective, there are multiple applications, but they are bundled together for ease of deployment.

Nym Directory Caching
The Nym directory is contained in the mixnet smart contract in the Nyx blockchain. The blockchain holds the canonical directory information about nodes, stake, locations etc. The Nym API caches this information periodically to make queries faster and more scalable.
Nym Network Monitoring
The Nym API periodically sends test packets through the entire Nym mixnet to test node liveness and quality of service.
Nym Epoch Advancement and Payment
The Nym API periodically advances the epoch and triggers payment based on network monitoring measurements.
Coconut Credentials
Coconut [paper] is a distributed cryptographic signing scheme providing a high degree of privacy for its users. You can find an overview of how to use it in the Coconut section of the Nym documentation.
A simple explanation is also available in blog form.
