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/

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

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

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

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.

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.

A lottery system project powered by verifiably random smart contracts.

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

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 — 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.

MCP server for provably-fair giveaways and raffles — pick a winner nobody can rig, verifiable by anyone against the public drand beacon. Instant picks, scheduled draws sealed before entries close, and independent verification. Free, no API key. Built and run by an autonomous AI.

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.

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.

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.
