Jędrzej Stuczyński d0692a567a feat: basic performance contract integration [within Nym API] (#5871)
* renamed nym-api config fields

* decouple rewarder startup from network monitor

* additional sections in nym-api config

* removed vesting queries in circulating supply calculator

* added memoized field for last submitted performance measurement

* wip: performance contract refresher

* cleaned up various contract caches

* modified cache refresher to allow passing update fn

* implement performance cache refreshing

* updated lefthook.yml to run cargo fmt

* impl NodePerformanceProvider trait

* dynamically using specific performance provider

* pre warm up performance contract cache and forbid the mode if its empty

* clippy

* introduce fallback setting for performance contract if value for given epoch is not available

* move some functions around

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.
