-A lightweight C++17 Distributed Hash Table implementation.
+A lightweight C++11 Distributed Hash Table implementation originally based on https://github.com/jech/dht by Juliusz Chroboczek.
 
-OpenDHT provides an easy to use distributed in-memory data store.
-Every node in the network can read and write values to the store.
-Values are distributed over the network, with redundancy.
-
- * Lightweight and scalable, designed for large networks and small devices
- * High resilience to network disruption
- * Public key cryptography layer providing optional data signature and encryption (using GnuTLS)
- * IPv4 and IPv6 support
- * Clean and powerful **C++17** map API
- * Bindings for **C, Rust & Python 3**
- * REST API with optional HTTP client+server with push notification support
+ * Light and fast C++11 Kademlia DHT library.
+ * Distributed shared key->value data-store
+ * Clean and powerful distributed map API with storage of arbitrary binary values of up to 56 KB.
+ * Optional public key cryptography layer providing data signature and encryption (using GnuTLS).
+ * IPv4 and IPv6 support.
+ * Python binding.
