Is Islamic Coin Quantum Safe?

Is Islamic Coin quantum safe? It is a question that deserves a rigorous technical answer, not a marketing deflection. ISLM runs on the Haqq Network, an EVM-compatible chain whose wallet security ultimately rests on the same elliptic-curve cryptography underpinning Ethereum. That means ISLM holders face the same Q-day exposure as every standard Ethereum wallet. This article unpacks the cryptographic stack ISLM relies on, models what a sufficiently powerful quantum computer could do to it, surveys any known migration plans, and explains how lattice-based post-quantum alternatives differ in practice.

What Cryptography Does Islamic Coin Use?

Islamic Coin (ISLM) is the native asset of the Haqq Network, a Cosmos SDK and EVM-compatible blockchain launched in 2022. Understanding its quantum-safety profile starts with understanding its cryptographic primitives.

The Haqq / Ethereum Address Model

Haqq Network inherits Ethereum's account model. To create a wallet address, the protocol:

1. Generates a 256-bit private key using a cryptographically secure random-number generator.
2. Derives a public key using secp256k1, the same elliptic-curve group used by Ethereum and Bitcoin.
3. Hashes the public key with Keccak-256 and takes the last 20 bytes to produce the familiar `0x…` address.

This is the Elliptic Curve Digital Signature Algorithm (ECDSA) over secp256k1. Every transaction a holder broadcasts is signed with this scheme. The security guarantee is that deriving a private key from a public key is computationally infeasible for a classical computer, because solving the elliptic-curve discrete logarithm problem (ECDLP) requires sub-exponential but still enormous classical effort.

Cosmos SDK Layer

Haqq is built on the Cosmos SDK, which by default supports two key types:

• secp256k1 (used for Ethereum-style accounts, which Haqq uses for EVM compatibility)
• ed25519 (used for validator consensus signatures)

Both secp256k1 and ed25519 are classical elliptic-curve schemes. Neither has been designed with quantum adversaries in mind.

Hashing Algorithms

Haqq uses SHA-256 and Keccak-256 for transaction hashing and Merkle tree construction. Grover's algorithm can theoretically halve the effective security of a hash function on a quantum computer, reducing 256-bit security to roughly 128-bit equivalent. That is a meaningful reduction but not an immediate existential threat, because Grover's attack is considerably harder to parallelise than Shor's algorithm and requires enormous quantum resources to run at speed.

The critical vulnerability is therefore not in the hash functions. It is in ECDSA and ed25519.

The Q-Day Threat: What Shor's Algorithm Actually Does

Q-day refers to the point at which a cryptographically relevant quantum computer (CRQC) can run Shor's algorithm at scale. Shor's algorithm solves the integer factorisation problem and the discrete logarithm problem in polynomial time. That directly breaks:

• ECDSA / secp256k1 (used by ISLM wallets and all Ethereum-compatible chains)
• EdDSA / ed25519 (used by Haqq validators)
• RSA (used in much of traditional internet infrastructure)

How the Attack Works Against ISLM Wallets

The attack path against an ISLM holder proceeds in two stages.

Stage 1: Public key exposure. Every time a wallet sends a transaction, the public key is broadcast to the network. A blockchain explorer reveals it permanently. An adversary with a CRQC could run Shor's algorithm against that public key and derive the corresponding private key in hours or days, depending on the quantum hardware's qubit count and error-correction capability.

Stage 2: Funds drain. With the private key recovered, the adversary signs a transaction sending all funds to a wallet they control. The network has no way to distinguish this from a legitimate transaction.

Wallets that have *never* sent a transaction have an additional layer of protection: the public key is not publicly known. The address itself is a hash of the public key, and Grover's attack on Keccak-256 is far less tractable than Shor's attack on ECDSA. However, the moment such a wallet transacts, the public key becomes exposed and the same vulnerability applies.

How Many Qubits Would It Take?

A 2022 paper from Mark Webber et al. (University of Sussex) estimated that breaking a 256-bit elliptic curve key in one hour would require approximately 317 million physical qubits with current error-correction overhead assumptions. Breaking it within a day would need roughly 13 million physical qubits. The largest publicly announced quantum processors as of 2024 (IBM Condor, Google Willow) sit in the range of hundreds to a few thousand physical qubits with limited error correction.

The timeline is uncertain. Most credible estimates from NIST and academic groups place a CRQC capable of breaking ECDSA somewhere in the 2030–2050 range, though the distribution is wide and a breakthrough could compress that window.

The core point: Q-day is not tomorrow, but it is not science fiction, and blockchain assets are permanent and addressable targets.

Does Islamic Coin Have a Quantum Migration Plan?

As of mid-2025, the Haqq Network's published documentation and roadmap do not reference a post-quantum cryptography (PQC) migration plan. This is not unusual. The majority of EVM-compatible chains, including Ethereum mainnet itself, are still in early research stages regarding PQC migration.

Ethereum's PQC Research as a Proxy

Because Haqq is EVM-compatible and tracks Ethereum tooling closely, Ethereum's approach sets a practical ceiling for what ISLM holders can reasonably expect:

• Ethereum's Vitalik Buterin published a post in 2024 outlining a potential hard-fork path to quantum-resistant addresses using STARKs (Scalable Transparent ARguments of Knowledge) and hash-based signature schemes.
• The proposal involves an account abstraction layer (EIP-7702 direction) where wallets can be upgraded to use quantum-resistant signing schemes without changing the base layer immediately.
• No firm Ethereum PQC hard-fork date has been announced.

A Haqq-specific PQC migration would likely require a similar hard-fork process, community governance vote, and substantial engineering work. The chain would need to support new key types natively, allow existing secp256k1 accounts to migrate to new PQC addresses, and maintain backward compatibility during a transition period. None of this has been announced for Haqq as of this writing.

What Would a Quantum-Safe Migration for ISLM Look Like?

Regardless of whether Haqq implements PQC at the protocol level, it is useful to understand what a genuine migration involves. There are several candidate approaches, each with trade-offs.

NIST PQC Standardised Algorithms

In August 2024, NIST finalised its first set of post-quantum cryptographic standards:

For a blockchain replacing ECDSA wallet signatures, ML-DSA (Dilithium) and FN-DSA (Falcon) are the primary candidates. Both are based on the hardness of lattice problems, specifically the Module Learning With Errors (MLWE) and NTRU lattice problems respectively. These are believed to be hard for both classical and quantum computers.

Hash-Based Signatures

XMSS (eXtended Merkle Signature Scheme) and SPHINCS+ use only hash function security, making their quantum resistance relatively easy to reason about. The downside is significantly larger signature sizes and, for XMSS, statefulness requirements that are operationally complex for a public blockchain.

Hybrid Schemes

A practical intermediate step many projects are exploring is hybrid signing, where a transaction requires both a classical ECDSA signature and a PQC signature. This preserves backward compatibility while adding quantum resistance. An attacker would need to break both schemes simultaneously to forge a transaction. The downside is increased transaction size and gas costs.

How Lattice-Based Post-Quantum Wallets Differ in Practice

For ISLM holders trying to understand the practical difference between their current Haqq wallet and a purpose-built post-quantum wallet, the contrast comes down to three dimensions.

Key Generation

A secp256k1 key pair involves 256-bit private and public keys, compact and fast to generate. A lattice-based key pair (e.g., Dilithium3) involves a private key of roughly 4,000 bytes and a public key of approximately 1,952 bytes. That is larger, but still manageable on modern hardware.

Signature Size and Verification

ECDSA produces a signature of roughly 64 bytes. A Dilithium3 signature is approximately 3,293 bytes. Falcon-512 produces about 666 bytes, making it the most compact viable lattice option. On a high-throughput chain, signature size matters for block space and fees.

Security Assumptions

ECDSA security rests on the ECDLP, which Shor's algorithm breaks. Lattice-based schemes rest on the hardness of problems like MLWE and NTRU, for which no known quantum algorithm provides a polynomial-time solution. NIST spent over six years evaluating these candidates before standardising them.

Projects building natively on NIST PQC standards, rather than retrofitting classical chains after the fact, inherit a stronger security posture from day one. BMIC.ai, for example, is a quantum-resistant wallet and token built on lattice-based, NIST PQC-aligned cryptography, designed explicitly to protect holdings against the Q-day scenario that threatens ECDSA-based assets like ISLM.

Risk Assessment: Practical Implications for ISLM Holders

Given the analysis above, here is a structured risk framework for current and prospective ISLM holders.

Near-Term (Now to 2029)

• Risk level: Low to moderate. No CRQC capable of breaking secp256k1 is expected in this window based on current public knowledge.
• Action: Standard security hygiene applies. Hardware wallets, seed phrase security, and avoiding address reuse reduce classical attack vectors.

Medium-Term (2030–2040)

• Risk level: Moderate to high and rising. The probability of a CRQC increases meaningfully in this window according to most academic threat models.
• Action: Monitor Haqq Network and Ethereum PQC roadmap announcements. If a migration mechanism is offered, prioritise migrating to a PQC-secured address.

Long-Term (Post-2040)

• Risk level: High if no migration has occurred. A CRQC in this window against secp256k1 is widely considered plausible.
• Action: Any ISLM holdings on un-migrated classical addresses would be at material risk. Migration to a PQC-native chain or wallet would be essential.

Structural Consideration: "Harvest Now, Decrypt Later"

Nation-state adversaries and sophisticated actors may already be archiving blockchain transaction data. If a CRQC becomes available in 2035, an adversary could retroactively derive private keys from public keys that were exposed in 2024 transactions. For high-value wallets, this harvest-now-decrypt-later strategy means the clock on quantum risk may already be running, even if a CRQC does not exist today.

Conclusion

Islamic Coin and the Haqq Network rely on secp256k1 ECDSA and ed25519, the same classical elliptic-curve cryptography used across virtually all major blockchains. Shor's algorithm, running on a sufficiently powerful quantum computer, would break both schemes. There is no publicly announced PQC migration plan for Haqq as of mid-2025. The near-term risk is low but the structural exposure is real, and Q-day timelines are compressing as quantum hardware investment accelerates.

Holders who take a long-term view of their ISLM position should track Haqq governance for any PQC migration proposals, understand the NIST-standardised lattice-based alternatives now under consideration across the industry, and evaluate whether a portion of their portfolio warrants migration to a natively quantum-resistant custody solution before Q-day arrives.
