Quantum-resistant coins are already sitting at $23.3 billion. By 2030, many of these coins could do 50x. → Quantum Resistant Ledger ( $QRL) → Qubic ( $QUBIC) → Quantus ( $QTC) Here are 3 projects building native post-quantum alternatives and how their token designs compare. 🟡Quantum Resistant Ledger ( $QRL): The Post-Quantum Pioneer ✦ Tech Used → XMSS + Hash-Based Security • Uses XMSS, a hash-based signature scheme covered by NIST SP 800-208. • Post-quantum signatures have been mandatory since its June 2018 mainnet launch. • Stateful signing requires careful tracking of one-time signature keys. QRL’s security approach starts with its signature system. Users have relied on post-quantum transaction signing since genesis, giving the project years of operational experience. That history matters. Deploying cryptography means maintaining wallets, managing keys, and keeping a network running over time. ✦ Network Design → Established Chain + Smart-Contract Expansion • Built around Proof-of-Work, with a planned transition toward Proof-of-Stake through Project Zond. • QRL 2.0 targets smart contracts and broader developer tooling. • Its roadmap aims to expand utility while preserving post-quantum protection. QRL’s next challenge is turning its security foundation into a broader application ecosystem. Smart contracts could give developers more reasons to build on the network. Execution, tooling, and adoption will determine whether that expansion creates lasting activity. ✦ Token → $QRL • Maximum supply of 105 million QRL. • Approximately 65 million allocated at genesis. • Remaining issuance follows a declining emission schedule. QRL combines capped supply with a security-focused network. Its longer-term economic case depends on whether users and developers create demand for blockspace and network services. A supply cap provides predictability. Adoption gives that scarcity economic relevance. My take: QRL is the established security contender, pairing a long production history with ambitions to support a broader developer ecosystem. 🔵Qubic ( $QUBIC): The Decentralized AI Compute Network ✦ Tech Used → Useful Proof-of-Work + Quorum Consensus + Aigarth Useful Proof-of-Work directs mining toward AI-related computational tasks. Aigarth is the project’s experimental AI initiative. Quorum consensus handles agreement over network execution. Qubic connects computational work with an AI research ambition. Its thesis is that distributed hardware can contribute useful outputs while supporting participation in the network. However, useful computation and quantum-resistant signatures address different problems. Qubic’s documented SchnorrQ signature system does not put it in the same native post-quantum category as QRL and Quantus. ✦ Network Design → Computors + AI Miners A set of 676 Computors executes transactions and smart contracts. Agreement requires a quorum of 451 Computors. Mining performance contributes to selection for the Computor set. The network separates computational competition from agreement over execution. Miners compete through computational work, while Computors maintain the shared network state. This makes participation, hardware requirements, and the distribution of influence important parts of the decentralization assessment. ✦ Token → $QUBIC Native asset used within the Qubic ecosystem. Rewards connect network participation with computational performance. Its economic thesis depends on demand for useful compute and applications. QUBIC’s value proposition centers on whether the network can turn distributed computation into services people use. Emission reductions and burns can affect supply, but they cannot establish product demand. The key test is whether computational outputs and applications develop sustainable economic value. My take: Qubic is the experimental AI compute contender, with potential tied to execution and adoption. It belongs in a decentralized computation comparison rather than being described as quantum-safe. ⚫Quantus ( $QTC): The Lattice-Based Privacy Contender ✦ Tech Used → ML-DSA + Post-Quantum Networking • Uses ML-DSA-87, the high-security signature parameter set under NIST FIPS 204. • Extends its post-quantum approach to peer-to-peer networking through ML-KEM. • Uses zero-knowledge aggregation to address the overhead of larger signatures. Quantus takes a lattice-based approach to transaction signing. Its design also addresses a practical problem: post-quantum signatures can be large. Aggregation aims to make that security more usable without allowing signature size to overwhelm network capacity. ✦ Network Design → Proof-of-Work + Privacy • Uses a custom Proof-of-Work design built around Poseidon2 hashing. • Targets approximately 12-second blocks. • Focuses on encrypted payments, wormhole addresses, and zero-knowledge infrastructure. Quantus combines post-quantum signing with a privacy-oriented payments design. That creates an ambitious technical proposition. Its younger network has had less time to demonstrate reliability, decentralization, and sustained usage than the two 2018 projects. ✦ Token → $QTC • Maximum supply of 21 million QTC. • Genesis allocation represents 27% of supply. • The remaining 73% is allocated to mining through declining emissions without discrete halvings. QTC has the clearest headline scarcity narrative of the three. But the cap is only one part of the picture. Genesis allocations, vesting, miner emissions, and available liquidity all influence how supply reaches the market. My take: QTC is the newer technical contender, combining lattice-based signatures, privacy ambitions, and capped supply—with greater uncertainty around execution and adoption. Conclusion: The Post-Quantum Edge Here’s how I see the three approaches: QRL → Established post-quantum security with a smart-contract expansion path. MCM → Payments-focused infrastructure with enforced key rotation and lightweight nodes. QTC → Lattice-based security combined with privacy and a strict supply cap. Final Rankings → These are qualitative assessments of the supplied project profiles, rather than security audit results. Operational Track Record: $QRL ≈ $MCM > $QTC QRL and Mochimo have operated since 2018. Quantus has a much shorter production history. Longevity provides evidence of operation, though it cannot guarantee future security. Application Expansion Ambition $QRL > $QTC > $MCM QRL targets a broader smart-contract ecosystem. Quantus emphasizes privacy and cryptographic infrastructure. Mochimo maintains a more focused payments proposition. Supply-Cap Simplicity: $QTC > $QRL > $MCM QTC’s 21-million cap is straightforward to communicate. QRL also has a defined cap. Mochimo’s continuing reward tail requires more explanation. This ranking says nothing about expected returns. My Takeaway: If your priority is an established post-quantum network with broader application ambitions → QRL. If your priority is lightweight payments with enforced one-time key handling → Mochimo. If your priority is lattice-based security, privacy, and capped supply → QTC. All three address the quantum-signature problem at the protocol level. Their long-term success still depends on implementation quality, usable wallets, economic security, and adoption. Post-quantum protection is the starting point. Building a network people use is the next test.

Most proof-of-work mining spends its computing power on guesses that are thrown away. Qubic’s mining algorithm, BPP-9000, puts that power to work. It searches for small neural networks instead. 🧵
