Скачать или смотреть I Shared my 12-Word Seed Phrase BY HAND (Software Optional) - Schiavinato Sharing - Shamir 2-of-3

If you self-custody crypto, a single seed phrase is a single point of failure. But relying on digital tools for backups creates a long-term dependency on software and hardware that might not exist in years to come.

What is Schiavinato Sharing?
In this video, I demonstrate Schiavinato Sharing, the first truly "Dual-Mode" threshold scheme. It allows you to shard your BIP39 mnemonic using air-gapped software for convenience, OR by hand using school-grade arithmetic for total sovereignty.

What you will see in this video:
12-Word Seed to 2-of-3 Shares: I manually split a standard mnemonic into three shares where any two can recover the original.

The Schiavinato RNG: Generating true entropy manually using bottle caps (minimal rejection method).

The Arithmetic Lock: Watch how the row checksums and Global Integrity Check (GIC) catch my math mistakes in real-time.

Manual Recovery: A demonstration of how to recover your funds in just 30 minutes with nothing but a pen, paper, and a basic calculator.

Key Features:
Universal BIP39 Compatibility: Works with the wallet you already have (Ledger, Trezor, BlueWallet, etc.).

No Vendor Lock-In: The recovered secret is a standard mnemonic, immediately usable anywhere.

Information-Theoretic Security: Powered by Shamir Secret Sharing over the prime field GF(2053).

Triple-Lock Architecture: Built-in error detection for both manual and digital execution.

⚠️ EXPERIMENTAL PROJECT (Jan 2026)
This is an experimental protocol in the review phase. The code and method are open-source and currently undergoing peer review. Use with caution during this validation phase.
