POSE Network Technical Briefing

Document Classification: Technical Documentation

Network: Testnet (Base Sepolia, Chain ID: 84532)

Last Updated: 2026-01-14

Version: v0.7

1. Executive Summary

The POSE (Proof of Self and Existence) Network is a Layer 0 + Layer 1 identity protocol that combines off-chain human-state verification with on-chain proof verification, staking, and validator networks. The protocol aims to provide human-proof security through continuous human verification requirements for consensus participation.

This document provides a comprehensive technical overview of the POSE network testnet deployment, including architecture, protocol specifications, implementation status, and operational infrastructure.
