QUORUM

2 of 3 Bitcoin
Multisignature Wallet

One physical device. Three independent hardware lanes.

Inside a single Quorum chassis, three separately isolated signer lanes generate and protect three independent keys. You carry, connect, unlock, and operate one device, while the hardware underneath preserves true 2-of-3 multisig robustness. It feels like a familiar single-signature wallet without collapsing security into one key or one hardware path.

THE PROBLEM

Bitcoin security still asks people to choose between simplicity and resilience.

WHY TODAY'S OPTIONS FALL SHORT

A single-key wallet is easy to operate, but one lost, stolen, or compromised key can become a total failure. Traditional multisig removes that single point of failure, yet often replaces it with several devices, disconnected interfaces, complicated backups, and a recovery process users may never confidently test.

HOW QUORUM ADDRESSES IT

Quorum puts a genuine 2-of-3 policy inside one purpose-built device. Three independent signer paths protect three independent keys while one coordinator guides setup, verification, signing, and recovery. No single key or signer can spend alone, but the user operates one coherent system.

THREE SIGNERS · THREE TRUST MODELS

Designed not to fail.

Three copies of the same hardware would repeat the same vulnerabilities three times. Quorum combines a transparent signer with two different defenses against physical extraction: Signer B hardens its persistent key, while Signer C retains no wallet seed after its session is cleared. Extracting Signer A alone still does not provide the two keys required to spend.

ASIGNER A

Transparent

Transparent verification lane

Signer A favors inspectability over tamper-resistant secrecy. Its open microcontroller and reviewable firmware make it the lane you can independently understand, audit, rebuild, and verify.

WHY THIS SIGNER EARNS A PLACE
  • Minimizes opaque hardware and vendor trust
  • Makes firmware behavior and key handling auditable
  • Provides a transparent counterweight to Signer B’s secure element
BSIGNER B

Hardened

Physical defense lane

Signer B is deliberately hardened for the attack Signer A does not optimize for: hands-on key extraction. Secure boot and protected key storage raise the cost of stealing a seed from a captured device.

WHY THIS SIGNER EARNS A PLACE
  • Resists physical probing and offline key extraction
  • Uses verified boot to reject unauthorized firmware
  • Keeps a persistent signer convenient without leaving raw seed material exposed
CSIGNER C

Stateless

Stateless recovery lane

Signer C stores no seed between sessions. It is loaded only when needed and communicates visually, so a dormant device has no persistent wallet secret to extract and no wired signing path to share with A or B.

WHY THIS SIGNER EARNS A PLACE
  • Leaves no seed at rest after power-down
  • Can sign only during an intentionally loaded session
  • Locking triggers a measured erase and verified empty reboot
SIMPLE ON GOOD DAYS · READY FOR BAD ONES

Security that survives
a bad day.

Most days, Quorum simply feels like one wallet. When something goes wrong, the 2-of-3 design gives you a clear way forward without turning recovery into an emergency.

01

A signer seed is lost

Choose the other two signers and keep using the wallet. Quorum guides you through moving funds to a fresh policy when you are ready.

No funds stranded.
02

One key is exposed

That key cannot spend alone. Use the two safe signers to authorize a move and replace the compromised signer.

One breach stays one breach—not a wallet takeover.
03

One entropy path is weak

The other seeds were created independently through different hardware paths. A problem in one generator is not repeated across the quorum.

Two independent approvals are still required.
04

No Trusted Third Party

Quorum is built around open-source software and open Bitcoin standards. All three keys are generated and held inside hardware lanes you control—no company, server, custodian, or outside co-signer owns a key or sits inside your spending policy.

You own every key. Any two under your control can sign.
ONE DEVICE · ONE GUIDED FLOW

Use it like
one wallet.

Quorum coordinates the signers for you. The interface shows the next useful action, keeps each key isolated, and guides both required approvals through one coherent flow.

1

Set up onceCreate or import three independent signers through one guided sequence.

2

Pick any twoChoose the available signers; Quorum handles the pairing.

3

Review one transactionSee the amount and destination clearly before either key approves.

4

Let Quorum finishThe device collects both signatures and returns one completed result.

ROBUST WITHOUT THE ROUTINE FRICTION

The hard parts stay underneath.

One place to operate

Create, unlock, review, sign, and recover from the same device instead of coordinating separate wallets and screens.

A clear next step

The interface tells you which signers are available, what needs approval, and when the quorum is complete.

Safety checks built in

Independent keys, visible transaction details, and two required approvals remain enforced even when the workflow feels simple.

Recovery ready from day one

Standard backups and inspectable wallet information are prepared before you need them—not after something goes wrong.

INTERACTION PROTOTYPE

Try multisig without
the multisig friction.

Walk through the same clear interface for setup, everyday signing, and recovery—while three independent keys remain protected underneath.
