Filecoin Cryptography Profile (Quantum Risk)
Verdict
As a chain, Filecoin should be modeled via its authorization cryptography—not market narratives. Filecoin is not quantum-proof as a blanket statement. Payment/actor keys and storage proving systems must be inventoried separately; both need documentation.
Overview
Filecoin (FIL) is included in Wave 6a as a top-market-cap L1 / native smart-chain target. This page is the chain cryptography profile.
Filecoin combines a token ledger with storage proving. Quantum risk may touch payment keys and long-term assumptions in proving systems differently.
Practitioners should split “can someone steal FIL?” from “do storage proofs need algorithm upgrades?”—and read current specs for each.

Cryptographic profile
- Signatures: BLS / secp256k1 actor crypto in Filecoin stacks (verify current wallet defaults)
- Hash: Filecoin proving and ledger hashing
- Public-key exposure: Miner and client keys; storage proofs are a separate crypto domain from payment keys.
What breaks
- Classical signatures authorizing FIL value movement under Shor-class adversaries once public keys are known
- Custodial hot wallets and exchange operational keys
- Bridges or wrapped representations with concentrated signers (if used)
Mitigations
- Inventory every key that can move FIL (self-custody, exchange, multisig)
- Prefer multiparty / hardware policies for treasuries
- Document bridges and wrapped asset paths
- Track ecosystem PQC research; do not assume branding equals deployment
- Use /assessment and chain comparison hubs on this site for program framing
FAQ
Is Proof-of-Spacetime quantum-proof?
Evaluate the specific proving scheme assumptions; do not equate storage proofs with PQC payment signatures.
Priority for holders?
Wallet/custody keys for FIL first; storage operator crypto second.
