World of Alchema
A dark fantasy RPG where your characters are truly yours. AI-generated portraits. Bitcoin Ordinals ownership. Free to play.
Blockchain-Native Game Engine
Alchema isn't just a game with NFTs bolted on. The entire world state lives on-chain, enabling mechanics impossible in traditional games.
On-Chain World Map
1:1 tile-based world where every location is a unique on-chain asset. Players can own, develop, and trade territory.
Blockchain Game Time
Dynamic time system driven by block height. Day/night cycles, seasons, and events all tied to the immutable ledger.
Pre-Ordained Events
Future game events inscribed on-chain before they occur. Provably fair, tamper-proof world progression.
Layered State
Character stats, inventory, and progress stored in composable on-chain layers. Portable across game versions.
AI Character Generation
Every character portrait is unique, generated by Google Imagen based on your choices. Select your race, faction, and appearance traits to forge a one-of-a-kind hero.
True Ownership on Bitcoin
Mint your characters as Bitcoin Ordinals. Your heroes exist permanently on the blockchain, owned by your wallet, not stored in a game database that can be wiped.
Explore a Living World
Navigate a 3D world map powered by Mapbox. Discover nine realms, each with unique locations, quests, and secrets waiting to be uncovered.
Built on bOpen Stack
Alchema demonstrates what's possible when you combine AI, blockchain, and modern web technologies. It's a reference implementation of the bOpen infrastructure—including content authenticity pipelines.
Every AI-generated portrait is cryptographically signed and inscribed as a Bitcoin Ordinal. Provenance from generation to ownership is immutable and verifiable—a model for any application handling AI-generated content.
