Quantum source mix
Use independent sources such as vacuum fluctuation homodyne detection, photon arrival time systems, and Bell-test beacons where the deployment profile allows it.

Qandom
The vacuum is not a seed.
Not a formula. Not a hidden server seed. A measurement.
Most blockchain randomness is math with a secret attached. Qandom is built around the stranger primitive: physical entropy, including lasers sampling quantum vacuum fluctuations, photon arrival times, and Bell-test beacons, made available as public oracle infrastructure.
Current market Classical randomness dominates on-chain oracle infrastructure.
Public gap No widely adopted quantum entropy oracle is live for major chains.
Public mission Blockchain randomness should be inspectable public infrastructure.
QSol path A Solana-native implementation for programs that need public auditability.
Why this matters
The weak point is not always the math. It is who gets to choose the seed.
Blockchains are deterministic by design. Validators must arrive at the same state, so randomness has to be imported. VRFs, TEEs, hash chains, and validator beacons are useful tools, but their outputs still come from computational systems, hidden seeds, enclaves, or committees. For ordinary games that may be enough. For regulated gambling, high-value mints, lotteries, auctions, and dispute sortition, the source of chance becomes a material risk.
A fair-looking output is not the same as an unchosen output. Qandom exists for the cases where that distinction matters.
The on-chain randomness stack is mostly classical
Chainlink, Pyth, Switchboard, ORAO Production randomness infrastructure, but built on classical cryptography, TEEs, or commit-reveal.
API3 QRNG The former dedicated multichain QRNG oracle shut down on January 1, 2025.
CURBy and Krown Genuine quantum-adjacent systems exist, but not as open callable oracles for major smart-contract ecosystems.
Qandom / QSol Qandom is the public entropy mission. QSol is the Solana implementation path.
Method
Physical entropy first. Public accountability immediately after.
The design is deliberately plain: obtain entropy from independent physical sources, bind the operator before reveal, publish the evidence needed for review, and keep public access separate from commercial packaging.
Commit before reveal
The operator commits to a hash before the entropy is revealed. A later substitution fails on-chain verification.
XOR aggregation
Multiple sources can be mixed so no single compromised source determines the final value.
Public baseline
Free public access, source manifests, and audit material stay part of the nonprofit commons. Paid products fund uptime and integrations.
The oracle shape
Request
A smart contract asks for entropy and records the callback target.
Acquire
The operator draws from upstream physical entropy sources.
Commit
The hash is finalized on chain before the value is public.
Reveal
The value and nonce verify the commitment, then callback execution receives entropy.
Applied project
One implementation path is QSol.
QSol, available through qsol.app, is one Solana implementation of the research: quantum-sourced entropy, CPI callbacks, multi-source mixing, and a latency target measured in a few slots rather than minutes. It is for teams that need audit-defensible randomness more than same-transaction speed.
Open qsol.app- Solana-native request, commit, reveal, and callback accounts.
- Target fulfillment around 1.6 to 3.0 seconds under normal network conditions.
- Designed for casinos, NFT trait reveals, lotteries, raffles, liquidation auctions, and market dispute workflows.
- Clear limitation: existing classical oracles remain better where the fastest latency is the only requirement.
Where the source starts to matter
Gambling
Provable fairness often proves consistency, not honest seed selection. Regulators care about the difference.
NFT mints
A rare-trait reveal can transfer millions in value through one entropy call.
Lotteries and auctions
Public draws, raffles, liquidation queues, and tie-breakers need audit trails that survive hostile review.
Nonprofit stance
The commons should not disappear when the commercial product changes.
Qandom separates the public mission from any single product. The public layer documents sources, exposes free access where sustainable, and keeps the language precise: real quantum entropy, not quantum-inspired branding.
Public entropy endpoints where operation costs allow.
Source status, provenance, and certification notes published in human-readable form.
Commercial projects, including QSol, used to fund maintenance, audits, and hardware access.
No claim of perfect trust: source compromise, operator liveness, and decentralized verification remain explicit risks.
Randomness is infrastructure now.
When chance decides money, access, ownership, or governance on chain, the source of chance becomes a public concern. Qandom is building that concern into public infrastructure.
