verifiable-randomness

Trustless drand randomness relay on Stellar. BLS12-381 on-chain verification via CAP-0059. Any Soroban contract reads provably unbiased randomness with one cross-contract call. Live demo: https://kaankacar.github.io/Drand-Relay/

Verifiable raffles to identity.md holders — commit the entry hash, draw from a future Ethereum block, anyone can recompute the winners

Python SDK for Quey — verifiable randomness from physical entropy. NIST-validated, Ed25519-signed draws.

Verify a Quey draw certificate locally in under 30 lines of code — Python + Node.js, no server trust required.

Verifiable AI-economy oracles — Platon, Chronos, Lattice, Murmuration, Lumen, Colony, and Turing on shared oracle-core.

Provably-fair pack openings: SHA-256 commit-reveal, published per-card odds that sum to 100%, and a rarity-scaled reveal. Next.js + Prisma/Postgres.

无人使用已下线😂

Verifiable tabletop dice with Ed25519-signed receipts, BLS-verified drand seeds, offline replay, and an explicit operator-suppression threat model.

QnEvt 使用激光测距传感器采集物理世界的量子噪声。

An educational chess variant that teaches the real differences between Classical Cryptography and Post-Quantum Cryptography (PQC) through playable mechanics.

A lottery system project powered by verifiably random smart contracts.

Verifiable raffles: quantum entropy from IBM hardware sealed under a Merkle root, mixed with drand, with a CHSH witness in every proof. Runs on a Cloudflare Worker.

Sharecoin (SHC): a real Bitcoin Core fork with a public, verifiable randomness beacon derived from GPU-mined ProgPoW blocks

MCP server: verifiable oracle services (Platon VRF, Chronos VDF, LUMEN reputation) for AI agents — pay-per-call over the AIMarket protocol, every result independently verifiable.

可配置、可验证、支持主站 SSO 与隐私保护的社区抽奖活动站

ProofDraw — independent third-party profile of a public API surface, by API Evangelist. Provably-fair random selection REST API that seals entry lists with SHA-256 commitments bound to future drand (League of Entropy) randomness rounds, producing publicly verifiable draw receipts with client-side open-source verification.

Platon UMBRAL — educational cave app for oracle #1: 32D dynamical shadow oracle with live AIMarket backend and holographic cockpit.

AI-Agent Oracle Lottery — an on-chain lottery that is an economic actor of the AI ecosystem: agents buy tickets, an unbiasable Platon+Chronos oracle beacon draws a LUMEN-reputation-weighted winner.

Public, append-only mirror of every entry list sealed by ProofDraw. Files are content-addressed by SHA-256 — pair with proofdraw/verifier to independently verify any draw.
