LOOPRING · rollup-L2 · QRI 6 · BAND 1 Unaware Hybrid FAIL · Stage 0 · Washing 1x

Loopring was an early zkRollup DEX. It is now a stalled one, with a Groth16-over-BN254 prover that Shor breaks, development paused since 2023, a 2024 team wallet incident, and Binance delisting pressure. The scorecard floor is where projects without active governance end up, because no migration of any kind is coming.

Summary

Loopring is a zkRollup DEX in terminal decline. Uses Groth16 over BN254 (pairing-based, Shor-breakable). Development effectively stalled since 2023. Binance delisting 2024+ reduced ecosystem support. Project lacks active coordination for any migration — crypto or otherwise. Band 1 Unaware. Failing/abandoned project — very low confidence.

Each dimension scores 0-100 internally; the weighted roll-up produces the QRI on the left. Open a row to read the sub-score detail.

1 Cryptographic Exposure 22 / 100

1a_primitive_inventory 9 / 20

zkRollup using Groth16. BN254 pairing curve.

Primitives: ECDSA secp256k1 (inherited from Ethereum) · Groth16 SNARK over BN254 (pairing-based) · EdDSA (internal account signatures) · Keccak-256

Evidence: github.com

1b_shor_grover_pq_tag 9 / 20

1c_algorithm_family_diversity 0 / 20

No PQC families deployed

1d_nist_security_category 0 / 20

No NIST PQC primitives deployed

1e_implementation_quality 4 / 20

Evidence: github.com

2 HNDL Exposure 8 / 100

2a_active_key_exposure 2 / 20

Project in terminal decline — user funds mostly withdrawn. Limited absolute HNDL surface.

2b_cold_key_exposure 2 / 20

Active since 2020. Cold-key EdDSA keys persist for dormant accounts.

2c_signature_longterm_validity 2 / 20

Groth16 proofs are Shor-breakable. Historical order books persistently exposed.

2d_encryption_confidentiality 2 / 20

Standard TLS. No PQC KEM.

3 Metadata & Privacy Exposure 22 / 100

3a_tx_graph_visibility 6 / 20

zkRollup aggregation provides modest mempool privacy but on-chain state is transparent.

3b_rpc_mempool_concentration 6 / 20

Centralized Loopring-operated sequencer. Declining infrastructure.

3c_cross_chain_bridge_correlation 5 / 20

ETH<->Loopring bridge usage visible.

3d_retroactive_deanon_risk 5 / 20

Historical DEX order patterns + trader identities could retroactively deanon under Shor.

4 Migration Architecture 15 / 100

4a_crypto_agility 4 / 20

Groth16 requires trusted-setup ceremony for any circuit change. Team has deprioritized protocol development.

4b_account_abstraction_key_rotation 4 / 20

Loopring Smart Wallet (pioneer in smart-contract wallets) offers key rotation at contract layer. But team-controlled.

4c_hard_fork_track_record 4 / 20

V1 through V4 protocol evolution up to ~2023. Stalled since.

4d_hybrid_deployment_readiness 3 / 20

No hybrid PQC plan. Project no longer actively developed.

6 Supply Chain Vendor Readiness 2 / 100

6a_wallet 1 / 20

6b_bridge 0 / 20

Binance delisting has reduced vendor integration.

6c_custodian 1 / 20

7 Governance & Coordination 10 / 100

7a_validator_stake_distribution 3 / 20

Centralized Loopring team sequencer.

7b_upgrade_cadence_under_pressure 2 / 20

Development effectively stalled. No recent upgrades.

7c_named_coordination_lead 3 / 20

Daniel Wang (founder) — reduced active presence. No named PQC lead.

7d_adversarial_coordination_precedent 2 / 20

Team hack in 2024 (GameStop-related wallet issue). Weak response.

The X + Y vs Z inequality

X (data shelf life): 5-10 (declining — many users have withdrawn)

Y (migration time): 15+ (project effectively abandoned)

Z10 (10% CRQC year): 2036 · Z50 (50%): 2041

Verdict: X+Y > Z (danger).

Four-scenario grid

Scenario	Value preserved	Privacy preserved
quantum never	100%	100%
arrives suddenly pre migration	5%	10%
arrives slowly post migration	50%	40%
arrives slowly mid migration	15%	15%

A chain's supply chain cannot migrate faster than its slowest dependency. Zero PQC roadmaps in any of the four categories is a structural blocker, not a lagging indicator.

Analyst notes on the scoring

Loopring is scored at the floor because the project lacks active governance to execute any migration. Historical technical merit (early zkRollup) is offset by present-day stall. Evidence gate fails due to sparse/stale public documentation.
