Post-Quantum Encryption Layer for Decentralized Protocols

C5/10March 12, 2026

WhatA drop-in cryptographic library and protocol extension that adds quantum-resistant encryption to decentralized identity and messaging protocols like Nostr, AT Protocol, and similar systems.

SignalTechnical users flag that current decentralized protocols storing encrypted data publicly are dangerously vulnerable to harvest-now-decrypt-later attacks, and no existing project is seriously addressing post-quantum readiness for the decentralized social stack.

Why NowQuantum computing timelines are compressing (Google Willow, IBM roadmaps), NIST finalized post-quantum standards (ML-KEM, ML-DSA) in 2024, and governments are mandating quantum-readiness transitions — but decentralized protocol teams are ignoring this entirely.

MarketProtocol foundations, enterprise adopters of decentralized identity (Bluesky, Nostr ecosystem), and security-conscious organizations; competitors are traditional PKI vendors who don't serve decentralized use cases; TAM follows the broader post-quantum migration market ($2B+ by 2030).

MoatDeep cryptographic expertise and first-mover integration with major decentralized protocols creates switching costs — once a protocol adopts your PQ extension, ripping it out is extremely painful.
