Sovereign: A Prove/Pull Protocol for Thermodynamically Correct Digital Communication

Abstract

Sovereign is a Prove/Pull communication protocol designed to address the structural imbalance of modern digital communication, where senders can impose cognitive and computational costs on recipients without corresponding friction. The protocol requires messages to carry a cryptographic proof of intent through one of three mechanisms: adaptive Proof-of-Work, private zero-knowledge proximity credentials, or registry-attested clearance tokens. Verification is performed by a decentralized Sovereign Audit Network (SAN), which attests that messages satisfy recipient-defined acceptance policies before delivery. This document presents the complete architectural specification of Sovereign, including the MessageEnvelope format, federated attestation protocol, dual Sparse Merkle Tree issuer registry with revocation support, Groth16 zero-knowledge proximity credential circuit, identity hierarchy, security assumptions, economic model, limitations, and phased deployment strategy. This release is Version 1.0 of the design specification. It is an unimplemented protocol proposal; all performance figures are engineering targets based on primitive benchmarks and require validation through future reference implementation. The work is published to establish a public technical record, invite peer review, and support future research, collaboration, and implementation efforts.
