Research, release notes, and migration thinking.
Compact updates from the Quorum project: product notes, post-quantum signing research, and practical guidance for teams managing Solana treasuries.
Quantum threat timelines for blockchains
A sourced view of CRQC estimates, what they mean for ECC blockchains, and how different cryptographic primitives fare.
Migration options for quantum-ready multisigs
The long-form version of Quorum's migration path: start post-quantum now, or move in stages without changing the vault address.
Solana's quantum-readiness decisions
The Solana ecosystem conversation around Falcon, Winternitz, SIMDs, and why app-level vaults matter before a protocol-wide migration.
Falcon-512 on Solana
Why Quorum supports FN-DSA/Falcon, what agencies say about it, and why compact signatures make it the practical Solana PQ candidate.
Winternitz and hash-based approval
Why Quorum includes a conservative hash-based signer, and what stateful one-time signatures demand from wallets and operators.
Ed25519 in a post-quantum migration
Why Solana's default signature scheme remains operationally important, and why it cannot be the final security boundary for long-lived authority.
Secp256k1 and cross-chain governance
How Ethereum-style signing fits into a Solana multisig, and why compatibility should not be mistaken for quantum readiness.
Why multisigs are not automatically quantum-safe
Why a classical quorum can still fail under future public-key recovery, and how signer policy needs to evolve.
One mnemonic, four identities
Why Quorum can derive classical and post-quantum identities from one recovery phrase without making PQ security depend on classical private keys.
Quantum readiness for Solana
What changes before Q-Day and why Solana teams should start migration planning now.
Quantum-ready multisig without a new operating model
Why Quorum treats post-quantum signing as a governance upgrade path, not a separate wallet category.
What SIMD-0461 changes for Falcon approvals
A compact explanation of how a native Falcon syscall improves the cost profile for post-quantum Solana approvals.
Devnet notes: approval flow polish
A short product update covering Quorum's latest devnet wallet and docs improvements.
