0xMiden Epoch: ZK Time-Locked Notes Interface

Video.Project.2.mp4

0xMiden Epoch is a minimalist, fully client-side interface designed to experiment with Miden Assembly (MASM) and native Account Abstraction on the 0xMiden network. It demonstrates how to issue cryptographic Time-Locked Notes without relying on heavy EVM smart contracts.

⚡ The Architecture

Instead of utilizing global state variables like Ethereum's block.timestamp, Miden Epoch leverages Miden's unique UTXO-based Note model. When a user initiates a lock, the interface dynamically constructs a MASM constraint script that asserts the push.env.block_number. The Heavy ZK-STARK proving algorithm is intended to be executed entirely locally via the @miden-sdk/miden-sdk WebWorker, ensuring total privacy until the exact unlock epoch is breached.

Core MASM Logic Implemented:

begin
    push.{target_block}
    push.env.block_number
    gte assert
    # ... asset transfer logic ...
end

🛠️ Built With

• Frontend: React + Vite + TypeScript
• Styling: Tailwind CSS (Vercel-Brutalist Aesthetic)
• Blockchain SDK: @miden-sdk/miden-sdk (Simulation Mode enabled for V1 UI demo)

💡 Core Use Cases

By pushing the time-lock execution to the edge (client-side STARK proofs), this architecture immediately powers:

1. Trustless Token Vesting: Team members / investors receive locked notes that mathematically cannot be consumed until the unlock epoch, entirely bypassing expensive EVM vesting contracts.
2. OTC Escrows: Over-the-counter trades where assets are locked for a specific dispute or clearing period.
3. Inheritance & Delayed Transfers: Programmable dead-man switches where funds unlock for specific beneficiaries in the future automatically.

🚀 Getting Started

Run locally for development:

npm install
npm run dev

Build for Production:

npm run build

📜 Notice

This is a conceptual UI prototype designed to push the boundaries of what is possible on client-side ZK-Rollups. Currently simulating proving delays for frontend demonstration purposes prior to full testnet network integration.

Built for the 0xMiden Builder Ecosystem.
