Subject: Montana — post-quantum blockchain reference paper I've been working on a new blockchain whose security rests entirely on post-quantum cryptographic primitives, with no transaction fees and time as the scarce resource in place of money. The paper is available at: https://github.com/efir369999/Montana/blob/main/Whitepaper Montana.md The main properties: Post-quantum signatures (ML-DSA-65) and key encapsulation (ML-KEM-768) from primitives up. No ECDSA, no curve25519, no RSA in the protocol. Consensus is a verifiable delay function over SHA-256 producing a globally ordered chain of windows of approximately 60 seconds each. Anti-spam operates on time, not on fees: per-identity per-window rates, account chain-length thresholds, seniority gating. No mint, no premine, no transaction fee. The single emission is 13 base units of Ɉ to the operator who completed each window's VDF. Architecturally targets one billion active accounts as the design baseline.
