MultiversX Cryptography & Quantum Risk Profile
Verdict
Profile view: MultiversX is not quantum-proof. Account authentication uses classical public-key crypto; sharding architecture is orthogonal to PQC.
Overview
This is the Wave 7e network/profile page for MultiversX (l1).
MultiversX (formerly Elrond) uses a sharded architecture for scale. Quantum risk for users remains signature schemes on accounts and validators.
Inventory EGLD treasuries and staking operator keys separately.
Verdict hub: /is-quantum-proof/multiversx. Asset framing: /crypto/egld.
Cryptographic profile
- Signatures: Ed25519-class account signatures (verify), Validator keys
- Hash: Protocol transaction hashing
- Public-key exposure: Accounts public; sharding does not hide public keys from verifiers.
- Verify current MultiversX account crypto.
What breaks
- Classical signatures authorizing EGLD value under Shor-class adversaries once public keys are known
- Custodial hot wallets and exchange operational keys
- Bridges, issuers, or operator sets outside ordinary user wallets
Mitigations
- Inventory every key that can move EGLD (self-custody, exchange, multisig, protocol roles)
- Name the host chain and bridge path for every balance
- Document operator/admin sets for L2s and apps
- Track ecosystem PQC research; branding is not deployment
- Use /assessment and claims methodology pages for program framing
FAQ
Sharding quantum-safe?
Sharding is a scalability design, not a post-quantum algorithm.
Staking?
Delegation/validator keys need the same inventory discipline as other PoS chains.
