Renewed interest in privacy tokens has pushed Quantus, a recently launched layer-1 blockchain, into the market spotlight. The project has been framed by some market participants as a post-quantum version of Zcash, with attention boosted by support from figures such as Balaji and by a broader rise in discussion around quantum-related security risks.
Quantus gains traction one month after mainnet launch
Crypto attention this week has centered on TOKEN2049 in Singapore. On Thursday, a side event called Quantum and Privacy Day was held, with Zcash, NEAR and Quantus listed among the organizers.
As quantum computing capabilities continue to advance, concerns about how they could affect existing network security models have moved beyond theory. That shift has brought more focus to post-quantum security across the crypto sector.
Quantus is a proof-of-work blockchain built from the base layer with future quantum threats in mind. The project describes itself as peer-to-peer electronic cash for the quantum era, with post-quantum cryptography, privacy and zero-knowledge proofs at the center of its design. Its stated goal is to address quantum security issues at the blockchain architecture level rather than retrofit them later.
The project argues that elliptic curve signature schemes used widely by major blockchains including Bitcoin, Ethereum and Solana could, in theory, be vulnerable to Shor’s algorithm once sufficiently powerful quantum computers emerge. Instead of relying on those schemes, Quantus uses ML-DSA, also known as Dilithium, as its core signature system. ML-DSA is one of the digital signature standards selected during the National Institute of Standards and Technology’s post-quantum cryptography standardization process.
In a recent interview, Quantus co-founder Christopher Smith said Bitcoin’s proposed BIP-360 offers one possible path toward a post-quantum upgrade by introducing new address types and allowing users to move funds into a new security model. Smith said that approach still leaves a practical problem: it only protects coins that are actively migrated.
By his account, that would leave holdings such as Satoshi Nakamoto’s bitcoin, along with coins that have been lost, forgotten or left unmanaged after a holder’s death, potentially unable to move into a new system even if a post-quantum upgrade is eventually adopted. Smith also said the crypto industry has spent the past decade layering new cryptographic systems on top of old ones, creating a stack that is highly complex and difficult to upgrade as a whole. That, he said, is why Quantus chose to build post-quantum security into the chain from the start.
Privacy is part of the pitch, but the model differs from Zcash
Privacy is the project’s other core narrative. On that front, Quantus shares some common ground with Zcash in that both use zero-knowledge proofs, but the privacy models are not the same.
Quantus says its private transfers work through Wormhole addresses. A user sends assets to an encrypted address, where the assets are provably burned. The holder then uses a locally generated zero-knowledge proof to remint the assets at any exit address, breaking the direct on-chain link between the sending address and the final receiving address.
Zcash, by contrast, uses zk-SNARKs and shielded pools to hide the sender, receiver and transaction amount while still keeping transparent addresses available, allowing users to choose whether to enter the shielded pool.
Large post-quantum signatures create an engineering challenge
Post-quantum security also comes with a clear engineering tradeoff: data size. Quantus uses ML-DSA-87 signatures, which are much larger than traditional elliptic curve signatures. If every transaction wrote a full post-quantum signature directly to the blockchain, signature data could quickly consume block space and weigh on throughput.
To address that issue, Quantus uses what it calls a ZK-plus-signature-aggregation mechanism. The system is built on STARK-based zero-knowledge proofs and uses Plonky2 to generate and aggregate proofs across multiple transactions. The aim is to compress what would otherwise be a large set of post-quantum signatures that need to be verified and stored one by one into a more compact aggregated proof.
Under that design, the chain does not need to process every signature individually. It only needs to verify the aggregated proof to confirm the validity of multiple transactions.
QTC has a 21 million cap and no halving schedule
On consensus and token design, Quantus follows a Bitcoin-like proof-of-work route. Its native token, QTC, has a maximum supply of 21 million, but the network does not include a halving mechanism.
For mining rewards, half of the fees from private transfers are burned and then reintroduced into future mining rewards on an exponential curve, according to the project’s design. The stated purpose is to ease the security budget problem that proof-of-work networks can face over time.
Quantus launched its mainnet on Sept. 9, 2026. According to data disclosed on its website, the network has more than 8,400 active accounts and more than 260,000 cumulative transactions. More recently, Quantus integrated with NEAR Intents, becoming the first post-quantum asset on the cross-chain trading protocol. Users can swap into QTC through multi-chain asset routing.
The project’s rise in visibility has coincided with gains in privacy assets such as ZEC and with a broader increase in discussion around quantum computing risks.
$2.42 million raised across two rounds, with Balaji leading the second
Beyond the project’s technical positioning, Quantus has drawn attention for its backers. Public information shows the project has completed two funding rounds totaling about $2.42 million.
The first round raised $1.65 million at a $40 million token valuation. The second raised $770,000 at a $100 million token valuation. The total is modest by market standards, but the investor list has become part of the story.
The second round was led by Balaji, with participation from AngelList co-founder Babak Nivi and Mert, founder of Solana infrastructure project Helius. Quantus co-founder Joseph Mattia previously said Balaji also serves as an adviser to the project.
Several of the names tied to Quantus also have close links to the Zcash community. Balaji is an early Zcash investor and long-time supporter who has repeatedly expressed strong bullish views on ZEC and at one point floated a $100,000 target price. Mert has also made positive public comments about Zcash. Another AngelList co-founder, Naval, was an early Zcash investor as well, participating in its early financing in 2015 and publicly saying that Bitcoin is insurance against fiat currency while Zcash is insurance against Bitcoin.
Genesis allocation becomes a flashpoint in community debate
That attention has not come without criticism. Quantus’ tokenomics have triggered debate, especially around the size of its genesis allocation. One community comment mocked the setup by saying, 「The quantum threat is still on the way, but the large genesis allocation is already in the bag.」
According to the project’s disclosed tokenomics, 27% of QTC’s total supply was minted at genesis. Of that, 23% was allocated to investors, founders and the team. Those tokens are locked for one year after mainnet launch and then released linearly over 36 months. Another 4% was allocated to the company.
Within that 4%, 1% was liquid at genesis and earmarked mainly for initial liquidity. The remaining roughly 3% is intended for later company operations and is also locked for one year before being released linearly over 36 months.
That structure has become the center of community criticism. The argument from critics is that Quantus leans on Bitcoin-like messaging around fixed supply, scarcity and proof-of-work, which can evoke ideas of digital gold and fair issuance. Unlike Bitcoin, however, which was issued gradually through mining in its early years, Quantus allocated a relatively large share of QTC to investors, founders, the team and the company at genesis. In the view of those critics, that creates the prospect of continued unlock-related sell pressure over the coming years.
For now, Quantus has used a mix of privacy and post-quantum technology narratives, along with capital backing, to enter a market window that is drawing attention. Whether its post-quantum design stands up over time, whether its privacy model translates into durable user demand, and whether network scale, liquidity and ecosystem activity keep growing remain open questions for the market.
