Mummai is an independent public file registry — a sovereign space for inscribing and preserving digital artifacts on the blockchain. It is an instance of the Metarium chain, deployed and maintained by Onemai Foundation.
Where digital objects are fragile and easily erased, Mummai provides a persistent, trustless record. Each file registered on Mummai receives a KURI — a permanent inscription that serves as its proof of existence, its marker in time. The registry operates as a public good: open, verifiable, and independent of any single authority.
Mummai draws from the Metarium principle that digital exploration deserves the same organic trails found in the physical world. Sketches, drafts, prototypes, discarded attempts — these artifacts of process gain significance over time. Mummai ensures they endure.
How It Works
Mummai is a single Metarium deployment set on its own path. When a file is registered, its cryptographic fingerprint is inscribed on-chain as a KURI — creating an immutable, timestamped proof of the file's existence. The registry does not store the file itself; it preserves the proof that the file existed at a specific moment in time.
This separation of content from proof is deliberate. The file may live anywhere — on IPFS, on a server, on a local drive. The KURI on Mummai is the sovereign anchor, the trustless attestation that persists regardless of where the file resides.
Principles
- Sovereignty — No central authority controls the registry. Proofs are self-validating and trustless.
- Persistence — Once inscribed, a KURI endures. The blockchain's continuity ensures the record outlasts any single system.
- Openness — The registry is public. Anyone can verify a file's proof of existence.
- Simplicity — The protocol is reduced to its essentials. A file, a hash, a timestamp, a KURI.
Context
Mummai is part of the broader ecosystem of Onemai Foundation, a Singapore-based non-profit that works to facilitate collaborative art and technology projects. The Foundation develops technological infrastructure on the blockchain to arrange experiential deliberations as a shared library.
The Metarium framework that powers Mummai was authored by Vignesh Sundaresan (Metakovan), a blockchain technologist exploring the extended and alternative possibilities of decentralized technology.
