Just one month after its mainnet launch, Quantus has quickly gained traction on its quantum-resistant and privacy narrative, with backing from Zcash-circle investors like Balaji further boosting attention—but its high genesis allocation has also sparked controversy.
Zcash's strong rally has reignited market attention on the privacy narrative, heating up a privacy sector that had long been quiet.
Recently, Quantus, an L1 project whose mainnet launched not long ago, has become a hot topic in the market. With its "quantum-resistant + privacy" positioning, Quantus quickly gained market attention and is even seen as a quantum-resistant version of Zcash. At the same time, support from privacy-narrative advocates such as Balaji has added further topicality to this new public chain.
Over the past few days, the crypto industry's attention has been focused on the TOKEN2049 conference held in Singapore. Today, a side event called "Quantum & Privacy Day" was held, and in addition to the well-known veteran privacy project Zcash and the public chain NEAR, Quantus—which has recently drawn community attention—was also one of the organizers.
As quantum computing capabilities continue to develop, the potential threat they pose to existing network security systems is gradually moving from theoretical discussion toward reality, and the crypto industry's attention on post-quantum security is heating up accordingly.
Quantus is a PoW public chain designed from its underlying architecture to address future quantum computing threats. The project positions itself as "peer-to-peer electronic cash built for the quantum era," focusing on post-quantum cryptography, privacy, and zero-knowledge proofs, and attempting to solve the quantum security issues that traditional public chains may face in the future from the very beginning of blockchain design.
It argues that the elliptic curve signature schemes widely used by mainstream blockchains such as Bitcoin, Ethereum, and Solana could theoretically be attacked by Shor's algorithm once sufficiently powerful quantum computers emerge. Unlike traditional approaches, Quantus adopts ML-DSA (Dilithium) as its core signature scheme. This algorithm is one of the digital signature standards selected during the U.S. National Institute of Standards and Technology (NIST) post-quantum cryptography standardization process, designed to resist cryptographic attacks that future quantum computers may bring.
Quantus co-founder Christopher Smith said in a recent interview that the BIP-360 proposal currently being discussed for Bitcoin offers a possible quantum-resistant upgrade path for Bitcoin. One of the core ideas of the proposal is to introduce a new quantum-resistant address type, allowing users to proactively migrate their assets into the new security system. But in his view, this approach still faces a practical problem: it can only protect assets that are proactively migrated. This means that the Bitcoin held by Satoshi Nakamoto, as well as some Bitcoin that has been lost, forgotten, or left unmanaged after the holder's death, may never be able to complete the migration even if a quantum-resistant solution is eventually implemented. Once sufficiently powerful quantum computers emerge, this portion of assets could theoretically still be exposed to attack risk. Moreover, Smith believes that the entire crypto industry has been continuously stacking new cryptographic schemes over the past decade, ultimately forming a layered, extremely complex system that is difficult to upgrade as a whole. Therefore, Quantus chose to incorporate post-quantum security into its underlying architecture from the very beginning of blockchain design.
In addition to quantum-resistant security, privacy is another core narrative of Quantus. On this point, it bears some similarity to Zcash—both use zero-knowledge proofs to achieve privacy protection—but the specific privacy models are not entirely identical. Quantus's private transactions are mainly implemented through Wormhole addresses. After a user sends assets to an encrypted address, the assets are provably destroyed, and the holder then uses a locally generated zero-knowledge proof to re-mint the assets at any exit address, thereby severing the direct on-chain link between the sending address and the final receiving address. In comparison, Zcash's private transactions are based on zk-SNARKs, hiding the sender, receiver, and transaction amount through a shielded pool, while retaining transparent addresses so users can choose whether to enter the shielded pool.
However, post-quantum security also brings new engineering challenges, the most obvious of which is data size. The ML-DSA-87 signature size adopted by Quantus is far larger than traditional elliptic curve signatures. If every transaction writes the complete post-quantum signature directly onto the blockchain, the signature data could quickly occupy a large amount of block space, putting pressure on network throughput.
To solve this problem, Quantus further introduces a "ZK + signature aggregation" mechanism. It uses a STARK-based zero-knowledge proof system and leverages Plonky2 to generate and aggregate proofs for multiple transactions, compressing the large number of post-quantum signatures that would otherwise need to be verified and stored one by one into a more compact aggregated proof. In this way, the chain does not need to process all signatures individually—it only needs to verify the aggregated proof to confirm the validity of multiple transactions.
In terms of consensus mechanism and token design, Quantus adopts a PoW route similar to Bitcoin. The total supply of its native token QTC is capped at 21 million, but there is no halving mechanism. In terms of mining reward distribution, half of the private transfer fees are burned and re-injected into future mining rewards according to an exponential curve, to alleviate the security budget problem that PoW networks may face.
Quantus's mainnet officially launched on September 9, 2026. According to data disclosed on its official website, the network currently has more than 8,400 active accounts and a cumulative transaction count exceeding 260,000. Recently, Quantus also officially integrated with NEAR Intents, a cross-chain trading protocol that has been gaining significant market traction, becoming the first post-quantum asset on the platform, allowing users to swap multi-chain assets for QTC.
It can be said that, riding on the market heat brought by the rise of privacy assets such as ZEC and the ongoing intensification of discussions around quantum computing risks, Quantus—which has only just launched—quickly gained market attention.
In addition to the project's own "quantum-resistant + privacy" positioning, its highly topical funding lineup is also an important reason Quantus has drawn market attention.
According to public information, Quantus has completed two funding rounds, raising a cumulative total of about $2.42 million. The first round raised $1.65 million at a $40 million token valuation, and the second round raised $770,000 at a $100 million token valuation. Judging purely by funding size, $2.42 million is not high, but the investor lineup behind it is quite topical.
The second round was led by Balaji, with participation from AngelList co-founder Babak Nivi and Mert, founder of the Solana ecosystem infrastructure project Helius. Quantus co-founder Joseph Mattia previously revealed that Balaji also serves as a project advisor.
More notably, the core investors behind Quantus have quite close ties to the Zcash circle. Balaji is an early investor and long-term supporter of Zcash, having publicly expressed extreme bullishness on ZEC on multiple occasions, even proposing a $100,000 target price; Mert has also publicly expressed positive views on Zcash on multiple occasions; Naval, another AngelList co-founder, is also an early Zcash investor, having participated in its early funding as early as 2015, and has publicly stated that Bitcoin is insurance against fiat currency, while Zcash is insurance against Bitcoin.
Therefore, riding on Zcash's market heat, Quantus's investor lineup has also added more room for imagination. However, Quantus's token ec
