This implementation is a high-performance Interledger Connector that supports many incoming and outgoing connections that are tied together by an ILPv4 packet-switching fabric.

This implementation supports the following features:

  • ILPv4: Interledger Protocol version for as defined in IL-RFC-27.

  • ILDCP: Interledger Dynamic Configuration Protocol as specified in IL-RFC-31.

  • ILP-over-HTTP: Allows for sending and receiving ILPv4 packets over HTTP as defined in IL-RFC-30.

  • Route Broadcast Protocol: Defines how Connectors can exchange routing table updates as defined in Route Broadcast Protocol.

  • Balance Tracking: Durably tracks account balance updates in a high-performance manner using Redis.

  • Persistent Data Storage: Account and other data can be stored using Postgres, MySQL, Oracle, MSSQL, and more.

To learn more about how this implementation is designed, see Connector Design.
