CapTP enables distributed object programming with capability security, allowing objects to reside anywhere on the network while interactions are governed by unforgeable references.
Create a small vat, spawn an actor, and perform a simple message exchange using CapTP primitives.

CapTP is a capability-based protocol that enables remote object invocation across networks. It allows objects to reside anywhere while interactions remain governed by unforgeable capability references, supporting heterogeneous transports like TCP, WebSocket, and Tor.
Promise pipelining chains multiple remote calls without waiting for intermediate results, reducing round-trips. CapTP implements this by allowing promises to be passed as arguments, so dependent operations queue locally and execute on the remote end in sequence.
Vats are isolated containers where distributed objects and actors reside. CapTP manages lifecycle semantics for vats, ensuring capability references remain unforgeable and interactions occur only through authorized channels, preventing unauthorized cross-vat access.
Yes, CapTP abstracts transport through pluggable layers. It supports TCP, WebSocket, NATS, Tor onion services, and Tailscale, allowing distributed objects to communicate using the most appropriate transport for each network segment.
Sturdy references are persistent, unforgeable capabilities that survive vat restarts and enable reconnection. CapTP uses them for long-lived distributed relationships; live references are ephemeral and work within active vat sessions.
CapTP implements Principle of Least Authority by allowing capabilities to be attenuated—restricted to a subset of operations before delegation. This ensures distributed objects receive only the minimal authority needed, reducing security risk across trust boundaries.
