The Sovereignty Showdown
(Which cold storage solution is truly best?)

Core Philosophy & Model

Feature	Paranoid Qrypto	Bitkey	BC Vault
Core Philosophy	Zero-Trust Sovereignty: Trust only yourself and open standards.	Assisted Self-Custody: A 2-of-3 multisig model that relies on a trusted third-party (Block, Inc.) for recovery.	Seedless Hardware Security: Eliminate the seed phrase as a point of failure. Trust the hardware and proprietary backup file.
2FA / TOTP Authenticator	YES: Uses Multi-Factor Encryption. Decryption requires Password + Pepper + a time-based 2FA/TOTP code. (2FA/TOTP only in Advanced and Ultimate version.)	NO: (Device has no such feature.)	NO: (Device has no such feature.)
Hardware/ Vendor Dependency	ZERO: Use, re-use, or upcycle any old phone or computer. No need to buy specific hardware, wait for delivery, or trust a vendor's supply chain. Your backup is timeless and independent of the company.	TOTAL: Requires their proprietary hardware, mobile app, and a constant connection to their server for the 3rd key.	TOTAL: Requires proprietary BC Vault hardware and their specific desktop app to function or restore.
Data Versatility	Any Text Data. Store passwords, private keys, bank data, seed phrases, etc. (over 2100 chars) in the form of an encrypted QR code.	Crypto Assets Only. Manages keys for a single 2-of-3 multisig wallet.	Crypto Assets Only. Can store up to 2000 separate wallets on one device.
Anonymity & Privacy	100% Anonymous. No personal information required.	LOW: Requires a phone number and account with Block, Inc., linking your identity to the wallet.	High. No KYC required for purchase or use.
Censorship risk by gov. and authorities	Extremely Low. No entity can be forced to block or restrict access. Only possible if the user chooses to comply and share the passwords.	High. The server-held key is a centralized point of control that can be targeted by authorities to block recovery or transactions.	Low. The device is offline, but the desktop app could be a point of censorship.
Cost Model	One-Time Purchase. Unlimited use.	Hardware Purchase. No recurring fees announced.	Hardware Purchase. For multiple locations multiple purchases needed.

Resilience & Disaster Recovery

Scenario	Paranoid Qrypto	Bitkey	BC Vault
Backup Redundancy	Simple & Cheap. Print or Laser engrave unlimited copies for different locations at minimal cost.	Service-Based. Relies on the third key held by the company's server. You do not control all your keys.	Digital Copy. Relies on making copies of the proprietary encrypted backup file to a microSD card or computer.
Data Redundancy (SSS)	Built-in Shamir's Secret Sharing: Split your backup into multiple pieces you control.	2-of-3 Multisig. A form of redundancy, but one of the three keys is always held by the company, not you.	None. The encrypted backup file is a single point of failure.
Fire & Flood Damage	Immune. A laser-engraved metal backup survives house fires and floods.	Vulnerable. Your phone and hardware device are both vulnerable. Recovery depends on the server.	Vulnerable. The electronic device and any microSD/computer backups are all vulnerable.
EMP / CME Event	Immune. A laser-engraved metal backup has no electronic components.	Vulnerable. Your phone and hardware device are both vulnerable. Recovery depends on the server.	Vulnerable. The device is electronic. Any digital backups are also vulnerable.
Long-Term Data Integrity (Bit Rot)	Immune. Physical laser engraving on metal does not degrade over time easily; it can last for centuries if properly stored.	Vulnerable. The device's flash memory is subject to data degradation. Relies on the company's server integrity.	Vulnerable. Claims FeRAM is more durable, but it is still an electronic component subject to failure over time.
Backup Method	Encrypted QR Code on a physical medium you control (paper, metal).	A server-held key controlled by a third party, used for recovery.	A proprietary encrypted file stored on a microSD card or computer.
Future-Proofing	Excellent. A QR code is a simple visual pattern. It will be readable for centuries on proper metal.	Very Poor. Entirely dependent on the survival and policies of Block, Inc. and its servers.	Poor. Relies on the company's survival to support its proprietary backup format and software.

Beyond Backups: Replace Your Hardware Wallet Entirely

While Paranoid Qrypto creates indestructible backups, its ultimate power lies in its ability to transform a device you already own into a sovereign signing device—making dedicated hardware wallets obsolete.

The Ultimate Paranoid Protocol:

1. Find Your Device: Take any old smartphone or laptop that you no longer use for daily tasks.
2. Create the Air-Gap: Perform a factory reset and ensure it never connects to the internet, Wi-Fi, or Bluetooth again. This is now your permanently offline air gapped signing device.
3. Install Paranoid Qrypto: Transfer the Paranoid Qrypto application file to the device via a trusted SD card or USB data device.
4. Create Your Indestructible Backup: Encrypt your seed phrase password or any text up to around 2100 characters into a QR code and transfer it out via SD card to be engraved on metal via direct capable Laser Engraver or Printer to print on paper, as many copies as you desire. This is your permanent backup.
5. Sign Transactions Securely: Use your air-gapped device with a compatible wallet app of your choice to sign transactions by scanning QR codes. Your private keys never touch an online machine.
6. Store or Destroy: For maximum security, you can power down and store your signing device in a safe place, or delete/format or even destroy it, knowing you can always recreate it on another old or new device using your indestructible QR code backup.

Why This Replaces a Hardware Wallet:

• Cost-Effective: It's free. You reuse hardware you already own instead of buying a new device.
• More Secure: A truly air-gapped, single-purpose device has a smaller attack surface than commercial hardware that must connect to online computers.
• Sustainable: Give your old electronics a new, high-security purpose instead of sending them to a landfill.
