par Noir is an open-source protocol for sovereign identity, building a more secure and equitable foundation for the internet.
Your digital identity is broken. Here's why.
Your personal information is scattered across hundreds of platforms, each a potential point of failure.
You don't own your digital identity—you rent it from Big Tech platforms that can revoke it at will.
Your identity is fragmented across countless logins, passwords, and accounts—none of which truly belong to you.
One master key. Infinite possibilities.
Imagine having one cryptographic key that unlocks your entire digital life—without giving anyone else control. That's par Noir. A protocol that gives you sovereign ownership of your digital identity.
Your digital identity, your rules. Every time.
Scenario: You want to access an age-restricted platform
Three core functions that change everything.
Your identity lives with you—not on corporate servers. One key unlocks your entire digital life.
Prove facts about yourself without revealing the underlying data. Age verification, qualifications, and more—all without exposing personal information.
Lost your key? Your trusted network can help you recover—without anyone having control.
A world where identity serves humanity, not corporations.
Your data becomes truly portable, working seamlessly across any platform or service that respects your sovereignty.
Personal AI assistants that know you intimately but are controlled by you entirely—no corporate surveillance.
Every device, every interaction, every connection is authenticated and secure—without sacrificing privacy.
Everything you need to know about par Noir and sovereign identity
par Noir is an open-source protocol for sovereign digital identity. It gives you complete ownership and control of your digital identity through cryptographic keys, zero-knowledge proofs, and decentralized storage.
A pN (par Noir identity) is your sovereign digital identity file stored locally on your device. It contains your encrypted personal data and credentials, secured by three components: the pN file itself, your pN name, and your passcode.
Zero-knowledge proofs allow you to prove facts about yourself without revealing the underlying data. For example, you can prove you're over 18 without sharing your age or birthday.
You can store any personal information you choose: identity documents, qualifications, preferences, relationships, and more. Everything is encrypted and only you control access.
IPFS (InterPlanetary File System) is a decentralized storage network that par Noir uses to store your encrypted metadata. It's resilient, censorship-resistant, and doesn't rely on any single company or server.
Unlike centralized identity providers or blockchain-based solutions, par Noir gives you complete ownership with no single point of failure. Your data is encrypted locally, metadata is decentralized, and you control all access through zero-knowledge proofs.
Visit pn.parnoir.com to create your pN. You'll choose a unique name, set a secure passcode, and your encrypted identity file will be generated and stored locally on your device. Your encrypted metadata will be stored on IPFS.
Your pN requires three components to decrypt: the pN file (stored locally on your device), your pN name (you remember), and your passcode (you remember). These three components together encrypt your metadata stored on IPFS. Without all three, your data remains completely inaccessible.
When a service needs verification, you choose what to prove. The system generates a cryptographic proof that confirms the fact without revealing any underlying data.
If you lose access to your pN, your trusted network can help you recover it through a decentralized process. No single person has control—it requires consensus from your chosen guardians.
You can update your pN data anytime. Changes to your local pN file are encrypted along with your metadata, which is then stored on IPFS. You maintain full control over what information is current and accurate.
Your pN file should be backed up securely. If lost, you can use social recovery through your trusted network, or create a new pN and re-establish your credentials. The protocol is designed to be resilient to device loss.
Services will display the par Noir logo or mention "par Noir compatible" when they support the protocol. You can also look for the pN authentication option during login or verification processes.
Traditional identity systems put your data in the hands of corporations and governments. Sovereign identity gives you control, privacy, and portability across all platforms and services.
Open source ensures transparency, security, and community ownership. Anyone can audit the code, contribute improvements, and build on the protocol without vendor lock-in.
Zero-knowledge proofs enable verification without surveillance. You can prove qualifications, age, or other facts without giving away your personal information or creating data trails.
Centralized identity systems create single points of failure, surveillance, and control. Decentralization ensures your identity can't be taken away, monitored, or controlled by any single entity.
Your digital identity affects everything from banking to healthcare to social media. Taking control means better privacy, security, and freedom in your digital life.
par Noir is completely free and open source because true sovereignty requires no financial barriers. There are no subscription fees, no hidden costs, and no vendor lock-in. You own your identity and data completely without ongoing payments.
Web3 requires true ownership and portability of digital assets, including identity. par Noir provides the missing identity layer that enables seamless interaction across decentralized applications while maintaining privacy and user control.
par Noir bridges Web2 and Web3 by allowing you to prove your existing credentials (from social media, banks, employers) without sharing the underlying data. This enables gradual migration while maintaining your current digital relationships and gaining sovereignty.
The par Noir protocol is designed as a foundation for sovereign identity. These examples represent just the beginning—any application that requires identity verification, data sharing, or privacy-preserving authentication can be built on top of par Noir. The protocol's open-source nature and zero-knowledge proof capabilities make it infinitely extensible for developers and organizations worldwide.
Prove you're over 18 to access age-restricted content or services without revealing your exact age, birthday, or any other personal information.
Prove you have a degree, certification, or license without sharing transcripts, personal details, or creating permanent records with employers.
Securely share medical records, test results, or vaccination status with healthcare providers while maintaining complete control over your data.
Prove your identity and financial standing to banks, lenders, or investment platforms without creating permanent data trails or sharing unnecessary information.
Verify your identity on social platforms to reduce bots and fake accounts while keeping your personal information private and secure.
Access government services, vote, or prove citizenship without creating centralized databases of personal information.
Prove your work history, skills, or employment status to potential employers without sharing sensitive personal details or creating permanent records.
Securely delegate tasks to personal AI agents that can access your information and act on your behalf. Your AI can communicate with other AI agents, make appointments, handle transactions, and manage your digital life while maintaining complete privacy and control.
Create a uniform identity protocol for the Internet of Things. Your smart home devices, wearables, and connected appliances can securely authenticate and communicate with each other using your pN, eliminating the need for multiple proprietary systems.
Enable your devices and AI agents to automatically interact with services on your behalf. Your smart car can pay for parking, your home can order groceries, and your AI can book travel—all while proving necessary credentials without exposing your personal data.
Whether you're here to use, build, or understand—there's a place for you in the par Noir ecosystem.
