Plebum Dominium

(PLAY-boom doh-MIN-ee-oom)

Absolute Ownership by the Common People

You make three Bitcoin keys at a table with no internet. Any two of them can move the coins. No hardware company has to exist for that to be true.

A computer that forgets the session. Dice you can see. Metal in three houses. Hardware signers are optional later — and only from more than one maker.

The whole job

Six stations. One table.

1

Why

One vendor, one phone, one house is the threat.

2

Two rooms

Online watches. Offline signs. Network stays off.

3

Check files

Real sites only. Two tools must agree.

4

Make keys

Keep 1–4. Three lists of 24 words.

5

Practice spend

Dust in. Two keys sign. Dust out.

6

Metal + map

Three plates. Three addresses.

One minute

Keys on your own terms

A quiet introduction. Play it at home. Then open the presentation when you are ready to work.

Pictures of the work

See it before you name it

The hard words live on the bench sheets. These drawings are what the homepage should lead with.

Two roomsThe seed never visits the internet. Only verified files and payment files cross on a USB.
Online watch-only desk and offline Tails signing desk with a data USB between them
DiceCasino dice. Keep 1–4. Throw 5 and 6 again. Do this three times for three keys.
Dice faces 1 through 4 kept, 5 and 6 thrown again
Two of threeAny two keys spend. One key alone cannot. Two keys in one drawer and the lock is gone.
Three keys around a vault that needs two signatures
Practice spendThe payment file walks. The seed stays seated. Full shutdown between Seed 1 and Seed 2.
Unsigned payment, first signature, second signature, broadcast
Three housesThree plates. Three addresses. The wallet map is not a third seed.
Three houses each holding one plate
House rulesFive walls. Everything else is furniture.

Tails with networking Disabled. 2-of-3 native SegWit (P2WSH), path m/48'/0'/0'/2'. Unsigned payment file = PSBT. Wallet map = output descriptor. Public watch key = xpub. Dice bits follow the unbiased 1–4 map; extra bits fold with SHA-256. Verify hashes and signatures before anything runs.
