BIP39
Each word has a defined position in the standardized English BIP39 word list, from 0 to 2047. SATONA converts this position into an 11-bit binary code. These 11 bits are then recorded on one line of the plate.
This mapping also makes the reverse operation possible: the 11 bits marked on the plate identify a position in the BIP39 list, which identifies the corresponding word.
BIP39 → 11 BITS

Download the complete BIP39 listThe English BIP39 list contains 2048 words in a defined order.
A word’s position in this list is its index.
Because 2048 = 2¹¹, 11 bits are enough to represent all 2048 possible positions.
SATONA uses this binary representation to record each word on one line of 11 positions.
In the standardized English BIP39 list, each word occupies a defined position.
This word → position → binary mapping is deterministic: the same word corresponds to the same index and the same 11-bit binary code within this list.
This principle makes it possible to recover the word from the binary code stored on SATONA.
2¹¹ = 2048
Eleven bits can therefore represent exactly the 2048 possible positions in the BIP39 list.
