Abstract:

   The Hash-Chain Context Transfer Protocol (HCTP) is a payload format
   and synchronization protocol for incrementally transferring an
   ordered, append-only sequence of conversational context between two
   endpoints over a bandwidth-constrained channel.  Acknowledged history
   is represented by a single fixed-size rolling hash commitment (the
   "static root"); only not-yet-acknowledged context blocks (the
   "dynamic window") are transmitted.  As a result, the per-message wire
   overhead attributable to history is constant and independent of the
   total number of previously acknowledged turns.  HCTP is transport-
   agnostic and carries no confidentiality or peer authentication of its
   own; it is intended to run over a secure transport.  This document
   specifies the HCTP data model, wire format, rolling-root computation,
   and synchronization state machine.
