BIP39 • BINARY

How to read your SATONA plate

No proprietary code. Each line simply contains the position of a BIP39 word written in binary.

One word → one position → 11 bits

The English BIP39 list contains 2,048 words.

Each word has a fixed position from 0 to 2,047.

SATONA does not transform the word arbitrarily. It simply takes this position and writes it as an 11-bit binary number.

0 00000000000

1 00000000001

2 00000000010

3 00000000011

4 00000000100

ABOUT ↓ position 3 ↓ 00000000011

11 bits can represent 2,048 different values. That is exactly the number of entries in the BIP39 list.

2¹¹ = 2048

1 BIP39 word → 1 position (0–2047) → 11 bits → 1 SATONA line

A marked square represents 1. An empty square represents 0.

To recover the word position, simply add the values of the marked squares.

0 0 0 0 1 0 1 0 1 1 0

64 + 16 + 4 + 2 = 86

The resulting number is the word position in the BIP39 list.

11 squares ↓ binary number ↓ decimal number ↓ BIP39 position ↓ original word

Your plate does not depend on SATONA for decoding.

Binary is a universal mathematical notation. There is no SATONA key, proprietary algorithm or server required to interpret the 11 squares.

With the BIP39 list and the values below, you can recover every position manually, then find the corresponding word in the BIP39 list.

SATONA plate → word position → BIP39 list → recovery phrase

This local educational tool only converts a number or an 11-bit string. It never asks for a recovery phrase and sends no network request.
