Quantum-safe Settlement at Market Speed

Executive finding

The migration problem is architectural.

A network can ship a post-quantum signer and still remain exposed through consensus, networking, privacy, custody, bridges or rigid algorithm dependencies. The benchmark therefore makes cryptographic agility a first-class requirement.

Signature ≠ system

A PQ transaction signature does not prove PQ-safe consensus, networking, privacy, custody, bridges or governance.

Agility ≠ roadmap

Crypto-agility means governed algorithm and key replacement without forcing asset or application migration.

Institutional readiness is broader than a signature

Institutional readiness also requires custody, privacy, controls, deterministic settlement and usable performance.

Research universe

Networks selected by infrastructure function, not token category.

Included networks materially inform institutional payments, stablecoins, tokenization, privacy, custody, performance, cryptographic migration or post-quantum readiness.

Market infrastructure

Arc, Tempo, Canton, Stellar, XRP Ledger, Ethereum and Besu are included because they are relevant to institutional payments, stablecoins, tokenization, private workflows or regulated settlement.

Cryptographic transition

Algorand, Starknet, Sui, Aptos, NEAR, Solana, Ethereum, Zcash and others are included because they expose concrete differences in PQ deployment, account design, privacy, migration and cryptographic agility.

Methodology

Eight dimensions. Crypto-agility carries the largest weight.

The rubric is built for banks, custodians, issuers, market infrastructure, procurement and risk teams. It is not an investment score or legal-compliance certification.

18%

Full-stack PQ coverage

Authorization, consensus, networking/KEX, privacy and control-plane cryptography.

20%

Cryptographic agility

Replace algorithms, keys and parameters without asset or app migration.

15%

Regulatory & standards readiness

FIPS alignment, KEX coverage, migration governance and procurement validation.

10%

Institutional controls & privacy

Private workflows, disclosure, auditability, governance and regulated-asset controls.

12%

Custody & migration

MPC/HSM compatibility, legacy-key migration, rotation and recovery.

10%

Performance, finality & PQ overhead

Current throughput/finality plus PQ size, verification and overhead where a PQ path exists. Classical baselines are labelled and do not count as PQ deployment.

8%

Deployment evidence

Network maturity and PQ-capability maturity are separated. A production classical network is not treated as production PQ.

7%

Evidence quality

Primary sources, reproducibility, audits and explicit limitations.

Regulatory rule: finalized FIPS 203/204/205 receive more credit than candidate/custom schemes. FIPS 206 is not final. Algorithm use alone does not establish FIPS 140-3, EO 14412 or legal compliance.
Core benchmark

A common framework across institutional and public blockchain infrastructure.

The research universe includes networks relevant to stablecoin settlement, tokenization, institutional privacy, payments, high-performance execution and active post-quantum migration.

How to read this table: Green is reserved for demonstrated full-stack 3/3 PQ coverage in this comparison. A live PQ capability on only one surface is shown as partial, not as a green system-level result. “Not PQ-safe” means the cited production or upstream surface is not currently credited as post-quantum safe. Mainnet describes deployment maturity, not quantum safety. Detailed evidence and sources remain in the project profiles and source sections below.

* Post-Quantum Compliance Readiness in this table means PQ standards/procurement alignment based on disclosed evidence. It is not a blanket legal-compliance certification; FIPS 140-3/CMVP and jurisdiction-specific obligations depend on the deployed module, configuration and use case.

Scores are publisher-assigned under the disclosed rubric below, not an independent credit rating or security certification. Every total is the sum of eight visible subscores; evidence state and deployment state are reported separately.

Competitive interpretation: PQ Safety is intentionally stack-level: a wallet/account PQ signature alone does not receive system-level credit if consensus and privacy remain non-PQ. “Post-Quantum Compliance Readiness” measures NIST/FIPS, EO 14412 migration/procurement alignment and deployability; it is not a blanket legal-compliance certification.
* Standardized PQ payload stress model: Reference transaction = 500 bytes. Throughput retention = B / (B − classical-auth bytes + PQ-auth bytes), assuming fixed byte capacity, one authorization per transaction, and no batching, compression, caching or protocol redesign. Generic signature-only replacement gives ~55% loss for Falcon-512 (666B), ~87% for ML-DSA-65 (3,309B), and ~94% for SLH-DSA-SHA2-128s (7,856B). Where the protocol transmits the PQ public key in the authorization envelope, project-specific models include it: Sui/NEAR ML-DSA-65 are ~91% and Algorand Falcon-1024 ~86% under the 500B reference. These are byte-bound stress estimates, not observed chain TPS losses. EternaX’s ~2% figure is its separate architecture model. Tempo’s scenario TPS figures apply the generic retention ratios to its cited 22,004 TPS classical run.

Regulatory & standards readiness

Post-quantum readiness is becoming a procurement requirement.

This benchmark measures standards alignment and institutional deployability, not legal compliance.

United States

EO 14412 targets PQ key establishment for federal high-impact systems by 31 December 2030 and digital signatures by 31 December 2031; a proposed FAR rule targets applicable NIST PQ FIPS for covered contractors by 31 December 2030.

NIST baseline

Final PQ standards are ML-KEM (FIPS 203), ML-DSA (FIPS 204) and SLH-DSA (FIPS 205). FN-DSA/Falcon remains under FIPS 206 standardization.

Europe & UK

EU and UK roadmaps target staged PQ migration through 2030–2035, with earlier planning and highest-priority transitions.

Hybrid TLS baseline

RFC 10024 hybrid TLS 1.3 enables standardized PQ/T key establishment. X25519MLKEM768 is the practical default; SecP256r1MLKEM768 supports FIPS-oriented profiles.

Critical distinction: a blockchain can use a quantum-resistant algorithm and still be unsuitable for regulated procurement if the algorithm is not finalized/approved for the required use case, if networking/key establishment remains classical, if cryptographic modules are not validated where required, or if the system cannot rotate to a future approved scheme.

Why FIPS 140-3 matters: FIPS 203/204/205 standardize algorithms; they do not automatically validate a specific HSM, KMS, wallet, validator or software module. Where regulated procurement requires a validated cryptographic module, implementation-level CMVP evidence is a separate gate.
PQ performance evidence

Measured first; modelled stress where no chain benchmark exists.

Published network results are separated from transparent byte-bound stress models. A modelled payload penalty is never presented as an observed TPS loss.

Standardized authorization-payload model

  • Reference signed transaction: 500B.
  • Fixed byte capacity; one authorization per transaction.
  • No batching, compression, public-key caching or protocol redesign.
  • Where the transaction carries the public key, the PQ public key is included.
  • Sensitivity range uses 250B–1KB reference transactions.

Current PQ size anchors

  • Falcon-512: ~666B signature.
  • ML-DSA-65: 3,309B signature + 1,952B public key.
  • SLH-DSA-SHA2-128s: 7,856B signature + 32B public key.
  • Algorand Falcon-1024: ~1.2KB compressed signature (max 1,423B) + 1,793B public key.

AptosSLH-DSA-SHA2-128s transaction authenticatorAIP-137 and Aptos Core implement SLH-DSA-SHA2-128s transaction authentication behind a feature gate.

AlgorandNative Falcon-1024 post-quantum accountsAlgorand v5.0.0 adds native Falcon-1024 accounts. The pqsig envelope carries the PQ public key and signature; the public key is 1,793B and the compressed signature is roughly 1.2KB, up to 1,423B.~86% loss @ 500B; ~75–92% sensitivityLive scheme + auth-payload modelAlgorand also added larger transactions and per-byte pricing.

NEARML-DSA-65 transaction / access keysNEAR supports ML-DSA-65 account/access-key signing. The transaction contains the signing public key; ML-DSA-65 uses a 1,952B public key and 3,309B signature.~91% loss @ 500B; ~84–95% sensitivityLive account path + auth-payload modelAccount-level model only. Validator/staking keys remain classical and NEAR has not published a chain-level PQ TPS delta.S20 / S34 / S51 / S91
Important: the model estimates a byte-capacity stress case, not actual chain TPS. Real throughput also depends on verification cost, block/packet limits, parallelism, batching, transaction mix, networking, storage, public-key caching and consensus. Solana’s ~90% figure is different: it is a reported testnet result, not a size-only model.
Cryptographic concentration risk

Assumption diversity is a security control.

The question is not whether lattice cryptography is broken. It is whether institutions should concentrate post-quantum signatures in one mathematical family.

Research deduction SLH-DSA · FIPS 205

Two of NIST’s three selected PQ signature families are structured-lattice based; SLH-DSA provides the standardized hash-based alternative. NIST explicitly sought non-structured-lattice signatures to diversify the portfolio.

01 · Concentration

Two signature families share one assumption class.

ML-DSA and FN-DSA/Falcon are structured-lattice signatures. SLH-DSA is hash-based, providing a different security foundation.

02 · Cryptanalysis

Late-stage confidence can still change.

HAWK reached NIST Round 3, then was withdrawn in July 2026 after new cryptanalysis. NIST states this does not break ML-DSA or ML-KEM.

03 · Diversification

SLH-DSA is the conservative diversity anchor.

FIPS 205 gives institutions a standardized, stateless hash-based signature path. Its main trade-off is systems cost, not standards maturity.

Architecture implication The question is not whether SLH-DSA is too large. It is whether infrastructure can absorb its cost without sacrificing market performance.
Important nuance: “hash-based” is not automatically conservative. Ethereum's Poseidon precompile EIP is stagnant, and its own security discussion emphasizes Poseidon's relative youth and algebraic structure; Ethereum continues active Poseidon cryptanalysis. The preference is for mature standardized hash foundations, not hashes generically. S94 S95
Shareable thesis · #assumption-diversity
Critical requirement

Crypto-agility is the decisive differentiator.

The test is operational: can cryptography change safely without reissuing assets, rebuilding applications or breaking custody?

What qualifies as real cryptographic agility

  • Algorithms are policy-selectable or abstracted from business logic.
  • Changing a signing primitive does not require asset reissuance.
  • Custody semantics survive key/scheme rotation.
  • Old and new schemes can coexist with explicit retirement controls.
  • Consensus, networking, privacy and authorization can migrate independently.
  • Wallet, HSM, MPC and recovery workflows have defined migration paths.

What does not qualify

  • A roadmap to replace one algorithm later.
  • A hard fork with no coexistence or rollback path.
  • Adding a PQ wallet while consensus/networking stay fixed.
  • Calling a plugin architecture crypto-agile without governed key/scheme migration.
  • A roadmap with no activation, coexistence, rollback or retirement mechanism.
  • Marketing “quantum-proof” claims with no public evidence boundary.
Deep profiles

The claim boundary matters.

Profiles separate live capability, implementation evidence and design/roadmap claims across the cryptographic stack.

Post-quantum blockchain FAQ

What is the EternaX Institutional Post-Quantum Blockchain Readiness Benchmark?

It is an institutional-readiness benchmark that evaluates post-quantum coverage, cryptographic agility, custody migration, privacy, performance, deployment evidence and standards quality. It is not a token-price or market-cap ranking.

Why is crypto-agility weighted at 20%?

Because post-quantum migration is not a one-time algorithm swap. Institutions must be able to replace algorithms, parameters and keys again if standards, cryptanalysis, regulation or hardware support changes. Crypto-agility remains the benchmark's largest single weight at 20%.

Does a post-quantum transaction signature make an entire blockchain quantum-safe?

No. Transaction authorization is only one surface. Consensus signatures, validator identity, key establishment, networking, privacy encryption, bridges, custody, governance and existing exposed keys can remain classically vulnerable.

Is EternaX mainnet today?

No. Pluto is a public EVM-compatible testnet. The benchmark treats EternaX's scored core capabilities as testnet-demonstrated evidence, not production-mainnet deployment.

How should the EternaX score be interpreted?

The score reflects the disclosed methodology across post-quantum coverage, cryptographic agility, institutional controls, custody migration, performance, deployment and evidence quality. EternaX receives 4.8/8 for deployment because Pluto is a public testnet. The score is a publisher-assigned research result, not an independent security certification.

Is Algorand post-quantum safe?

Algorand v5.0.0 supports native Falcon-1024 post-quantum accounts on mainnet. That does not make every Algorand surface post-quantum: consensus/VRF migration remains separate roadmap work.

Is Starknet post-quantum safe?

Starknet has meaningful post-quantum building blocks but is not yet end-to-end post-quantum. Its STARK proving layer is PQ-friendly, it has demonstrated an experimental Falcon-512 account on Mainnet, and v0.14.3 moved selected OS/configuration hashing from Pedersen to a BLAKE2s-256-based construction. Falcon remains experimental/unaudited, FIPS 206 is not final, and trie/address plus other classical dependencies still require migration.

Is Ethereum post-quantum safe today?

No. The Ethereum Foundation has a dedicated multi-layer post-quantum program covering execution, consensus and data, but describes the transition as a coordinated migration over years. Current production consensus still uses classical cryptography.

Why is Zcash included?

Because PQ readiness includes confidentiality and recoverability, not only signatures. Ironwood adds quantum recoverability, but Zcash's own ZIPs explicitly state that this does not by itself make Zcash secure against quantum attacks. Project Tachyon targets future post-quantum privacy.

How are native post-quantum networks treated?

Native post-quantum signatures are important evidence, but the benchmark evaluates institutional readiness across multiple dimensions. A live PQ signature can score strongly on authorization while custody, privacy, performance, migration and institutional controls are assessed separately.

How should readers interpret EternaX performance figures?

EternaX throughput, finality and PQ-overhead figures are treated as project-reported targets or modelled/testnet claims unless independently reproduced. The benchmark never treats a target as production mainnet evidence.

How are evidence grades defined?

A = live mainnet/on-chain or official release evidence; B = public testnet, reproducible code or formal technical implementation; C = official roadmap/proposal; D = third-party pilot or secondary technical evidence; E = marketing-only claim. Mixed grades indicate different surfaces have different evidence maturity.

Which blockchains are included in the benchmark?

The benchmark includes EternaX, Arc, Tempo, Canton Network, Zcash, Algorand, Starknet, Sui, NEAR, XRP Ledger, Hedera, Ethereum, Solana, Aptos, Stellar, Hyperledger Besu and Bitcoin. They are selected because they illuminate different institutional requirements including payments, tokenization, privacy, custody, performance and cryptographic migration.

Why are Arc and Tempo included in a post-quantum readiness benchmark?

The benchmark is an institutional blockchain readiness study with post-quantum security as a critical dimension, not a list of quantum-resistant coins. Arc and Tempo are relevant because they are purpose-built financial infrastructure for stablecoins, payments and settlement; their current cryptographic posture provides an important baseline for migration analysis.

Why is Canton Network included?

Canton is included because institutional privacy, regulated workflows and cryptographic extensibility are central to market-infrastructure readiness. Its production architecture provides a useful comparison for how cryptographic migration interacts with real institutional operating requirements.

Is Arc post-quantum safe?

No post-quantum transaction, validator or key-establishment scheme is credited to Arc in this benchmark. Arc is included because its stablecoin-finance, privacy and institutional-settlement architecture provides an important migration baseline.

Is Tempo post-quantum safe?

No PQ signature or KEX is currently credited. Tempo’s TIP-1020 is live on Mainnet and provides a stable verifier interface for secp256k1, P-256 and WebAuthn, which is useful for future agility but is not itself post-quantum. Tempo also documents opt-in privacy for balances/transfers.

Is Canton Network post-quantum safe?

No. Digital Asset’s CISO states that Canton currently uses ECC. The planned migration is to add native PQC through Canton’s existing extensible cryptographic API; ML-DSA is one candidate and hybrid schemes are also being considered.

Is Sui post-quantum safe?

Sui has built ML-DSA-65 account support and an SLH-DSA vault path, with staged activation. The benchmark does not treat Sui as fully post-quantum across consensus, networking and privacy.

Is NEAR post-quantum safe?

NEAR has stable protocol support for ML-DSA-65 transaction and access keys. That is meaningful account-layer progress, but consensus, networking, custody and privacy remain separate cryptographic surfaces.

Is Solana post-quantum safe?

Not protocol-wide today. Solana has Winternitz-vault usage and Falcon research, and Anza has published Quantumglow, a post-quantum research redesign of Alpenglow consensus. Quantumglow is research-stage rather than deployed, and wallet/account/networking migration remains separate work.

Is Aptos post-quantum safe?

Not as a live Mainnet capability in this benchmark. AIP-137 specifies SLH-DSA-SHA2-128s post-quantum accounts and Aptos Core contains feature-gated support, but the VM rejects the scheme unless the feature is enabled. The implementation path is real; production activation remains a separate milestone.

Is XRP Ledger post-quantum safe?

Not in production today. Ripple targets full PQ readiness by 2028 and has published a phased program including NIST-scheme testing, an ML-DSA AlphaNet proof of concept, validator testing, Devnet work and an early PQ custody-wallet prototype. Current production signing remains secp256k1/Ed25519.

Is Hedera post-quantum safe?

Not today. Hedera currently uses ECDSA secp256k1 and Ed25519 for accounts/transactions and classical TLS. Its published roadmap sequences PQ TLS for nodes and clients, hybrid event signing, and then a new PQ user-key type after FIPS 206 finalization, with ML-DSA as fallback if needed.

Is Stellar post-quantum safe?

No. Classic Stellar accounts still use Ed25519. Soroban contract accounts now provide custom authentication, including passkey/P-256 and arbitrary contract-verified policies, which improves crypto-agility, but no production PQ key type or PQ verifier is credited.

Is Hyperledger Besu post-quantum safe?

Upstream Besu is not credited with native post-quantum transaction or QBFT validator signatures. Enterprise deployments can add custom controls or overlays, but those should be assessed separately from base Besu.

What is the difference between post-quantum security and crypto-agility?

Post-quantum security describes resistance to known quantum attacks. Crypto-agility describes the operational ability to replace algorithms, parameters and keys when cryptography changes. A system can support a PQ algorithm and still have weak crypto-agility.

What does regulatory and standards readiness mean in this benchmark?

It measures whether a network's published cryptography aligns with finalized post-quantum standards, whether key establishment and signatures are both addressed, whether algorithms can be rotated as standards change, and whether implementation/validation evidence exists for institutional procurement. It is not a legal-compliance certification.

Does using a NIST FIPS algorithm make a blockchain compliant with Executive Order 14412?

No. EO 14412 applies to federal systems and related procurement requirements. Using FIPS 204 or FIPS 205 can improve standards alignment for digital signatures, but EO readiness also involves key establishment, migration planning, inventories/CBOM, implementation validation and the specific system's procurement context.

Which NIST post-quantum standards are finalized?

As of 24 August 2026, FIPS 203 standardizes ML-KEM for key establishment, FIPS 204 standardizes ML-DSA for digital signatures, and FIPS 205 standardizes SLH-DSA for digital signatures. FN-DSA/Falcon is still being standardized as FIPS 206 and is not treated as a finalized FIPS signature in this benchmark.

Why is FIPS 140-3 or CMVP separate from FIPS 204 and FIPS 205?

FIPS 204 and FIPS 205 specify algorithms. FIPS 140-3 and the Cryptographic Module Validation Program concern validation of concrete cryptographic modules. An institution may therefore need both an approved algorithm and an implementation that satisfies the applicable module-validation or procurement requirement.

How are post-quantum performance numbers classified?

Measured numbers come from published implementation, testnet or mainnet observations. Derived numbers come from standardized signature/key sizes or protocol limits. Modelled numbers use disclosed assumptions. Modelled payload penalties are explicitly labelled and are never presented as observed chain TPS losses.

How does EternaX make blockchain networking post-quantum safe?

EternaX uses standardized hybrid TLS 1.3 rather than proprietary networking cryptography. Its networking profile uses IETF RFC 10024 PQ/T key-establishment groups backed by ML-KEM from NIST FIPS 203, with X25519MLKEM768 as the practical default and SecP256r1MLKEM768 available for FIPS-oriented institutional deployments. Because TLS groups are negotiated and policy-selectable, the networking layer can move to future approved groups without redesigning the chain or applications.

What is EternaX's target throughput and settlement speed?

EternaX targets 50,000–200,000 transactions per second with approximately 2% modelled post-quantum throughput overhead, 20–50ms soft finality and 400–520ms hard finality. The design also targets transaction fees below $0.001 and 24/7/365 settlement. These are published EternaX design targets rather than independently measured production-mainnet results.

Is EternaX consensus post-quantum?

Yes. Post-quantum consensus capability is demonstrated on the Pluto public testnet and is scored as testnet evidence (B), not as an architecture-only claim.

Does EternaX provide institutional privacy?

Yes. Institutional privacy, privacy between participants, selective disclosure and auditable regulatory access are demonstrated on the Pluto public testnet and scored as testnet evidence (B).

Is EternaX fully crypto-agile?

Yes at the current testnet evidence level. Pluto demonstrates crypto-agility across authorization, consensus, networking/key establishment, privacy and custody, so these surfaces are scored as testnet evidence (B).

Why does the benchmark treat SLH-DSA as a diversification anchor?

Because ML-DSA and FN-DSA/Falcon rely on structured-lattice assumptions, while SLH-DSA is standardized under FIPS 205 on a different, hash-based foundation. NIST explicitly sought non-structured-lattice signatures to diversify the PQ portfolio. The trade-off is larger signatures and systems cost.
