Buantum is the Layer 1 where privacy is the protocol, post-quantum cryptography is the foundation, and randomness comes from physics. Four co-equal pillars — Privacy, PQC, QRNG, QKD — locked in from genesis. No opt-in. No migration window. No exceptions.
Buantum's design rests on four properties, each independent and each enforced at the protocol layer. Privacy is not a feature. Quantum resistance is not a roadmap item. Quantum entropy is not optional. QKD is not theoretical. All four are architectural from block zero.
Every transaction is shielded. Sender, recipient, amount, and contract state are protected by ZK-STARKs — hash-based, no elliptic-curve assumptions, quantum-resistant by construction. Confidential execution via TEE or FHE depending on the trust model. Auditors get view keys, never spending power. REF · STARKWARE / STARKNET · OASIS SAPPHIRE · FHENIX
ML-DSA-65 for signatures. ML-KEM-768 for key encapsulation. SLH-DSA for long-term identity. AES-256-GCM for symmetric. SHAKE-256 throughout. No ECDSA. No EdDSA. No Schnorr. No BLS. No fallback to anything Shor's algorithm can touch. REF · NIST FIPS 203 / 204 / 205 · AUG 2024
Every cryptographic seed carries quantum entropy. Hardware QRNG from certified chips, decentralized API entropy via vacuum fluctuations, mixed with jitter and conditioned through SHAKE-256. Classical PRNGs are banned as primary sources. On-chain randomness via threshold-aggregated QRNG plus VDF. REF · ID QUANTIQUE QUANTIS · ANU QRNG · BSI AIS31
Core validators exchange session keys over QKD fiber. Eavesdropping disturbs the quantum state and is physically detectable. Always hybrid with ML-KEM: an adversary must break the channel and the lattice simultaneously. BB84, TF-QKD, MDI-QKD by distance and topology. REF · ID QUANTIQUE CLAVIS XG · ETSI QKD STANDARDS
What Buantum is depends on what you need from it. The protocol is dense underneath — but the guarantees translate cleanly to three audiences who all want the same thing: assets that stay theirs.
Build apps without hand-rolling shielded pools, MPC, or trust assumptions. The protocol handles it.
Settle real value with privacy that doesn't preclude regulated audit. View keys for auditors. Spend keys for you.
Balance, transactions, and counterparties are private by default. Keys are post-quantum. Randomness is real.
Every choice is named, sourced, and traceable to a published standard or a production reference. No proprietary primitives. No hidden trust assumptions. If it isn't in the spec sheet, it isn't in the protocol.
Every smart contract deployed on Buantum must commit to a behavioral specification at deploy time. Execution that deviates from the committed spec is rejected by the protocol — silently, automatically, before any state changes. Behavior becomes provably detectable, even when the contract code itself is encrypted.
Define entry points, state transitions, admin paths, and fund-movement conditions in a machine-checkable language (TLA+ / Lean / Buantum DSL).
A SHAKE-256 commitment of the spec is published to the on-chain registry, signed by the deployer's ML-DSA key. Immutable. Publicly readable.
Each transaction generates a ZK-STARK proof that execution followed a valid path defined in the committed spec — without revealing inputs or state.
Proofs that don't verify against the committed spec fail at consensus. Hidden behavior cannot execute silently. Upgrades require new commitments — old ones stay in history.
This system detects deviation from the committed spec — not whether the spec itself is fair or safe. A developer can commit to a malicious spec; the protocol can't prevent that. What it prevents is hidden behavior that contradicts the public commitment. The trust shifts from "read the bytecode you can't read" to "read the spec everyone can read." This is an architectural pattern; the toolchain ships as part of the Buantum SDK.
The applications where the ability to be watched, front-run, or decrypted later is a non-starter. Buantum is built for that threshold.
Move value without revealing sender, recipient, amount, or pattern. Default behavior, not a feature toggle.
Lending, AMMs, perps where positions stay private and execution can't be front-run. MEV bots see only encrypted blobs.
Bonds, deeds, funds, and equity with cryptographic privacy and ZK-based jurisdiction proofs. Compliance without surveillance.
App-chains where business data is FHE- or TEE-encrypted at execution and committed under Buantum's finality.
Prove jurisdiction, age, sanction status, or accreditation via ZK-STARKs over SLH-DSA-anchored credentials. No raw identity on-chain.
Run inference inside TEE / FHE with ZK-STARK proofs that the committed model was used. Input, output, and weights stay private.
Account security on Buantum is a protocol mode, not a contract you deploy. The dual-key structure separates spending from viewing — so an auditor never has the ability to move funds, and a leaked key isn't a leaked balance.
ML-DSA spend key signs transactions. ML-KEM view key decrypts transaction data for the holder or a designated auditor. The view key cannot spend; the spend key cannot reveal historical state to a third party.
Require M-of-N ML-DSA signatures to authorize a transaction. Built into the protocol — no third-party contract, no per-app integration. Multisig accounts are indistinguishable from single-sig accounts on-chain.
Attach sandboxed policy that runs on every transaction: spend limits, time locks, allow-listed recipients, social recovery, tiered authorization. Opt-in. Simple accounts stay simple.
Everything to ship on the private, post-quantum L1 — architecture specs, RPC references, integration guides, and the spec-commitment toolchain.
