affinidi-did-resolver-cache-server

A standalone network service for resolving and caching DID Documents at scale. Uses WebSockets for transport and operates a service-wide cache backed by a pool of parallel resolvers.

Requests from clients can be multiplexed and may be responded to out of order. The client SDK handles matching results to requests.
