Architecture

The three-layer Quorum architecture: program, SDK/keyring, and wallet.

Architecture

Quorum has three layers: the on-chain program, the signing SDK/keyring, and the wallet interface.

Program layer

The program stores multisig membership, thresholds, proposal counters, and vote state. Authorization is verified from signed canonical preimages.

Multisig

Root account for thresholds, members, stale proposal index, and transaction counter.

Proposal

Records vault actions or settings actions and tracks approval state.

SDK layer

The SDK derives PDAs, builds instructions, and prepares signing payloads for the wallet.

derive-vault.ts
import { deriveVaultPda } from '@pq-msig/sdk'
 
const [vault] = deriveVaultPda(multisig, 0)

Wallet layer

The wallet coordinates fee payer transactions, member signatures, identity registration, and signing prompts. It should be replaceable without changing the program or SDK contract.

App approval flow

Follow the operator-facing state machine from proposal to execution.

Wallet signing model

Understand how wallet prompts map to canonical preimages and packet signatures.
