<ul>
  <li><strong>hArk (hash-lock-Ark)</strong>: A major Ark protocol evolution that eliminates synchronous interactivity during rounds. Instead of requiring all participants to be online simultaneously to sign transactions, the server generates unique secrets for each VTXO, allowing participants to claim their funds asynchronously.
    <ul>

    </ul>
  </li>
  <li><strong>ZK Statechains</strong>: Replaces traditional statechain ledgers with zero-knowledge proofs to validate ownership transfers of Bitcoin UTXOs while maintaining privacy, combining statechain exit mechanics with a “ZK Ledger” that proves key changes and timelock decrements.
    <ul>

    </ul>
  </li>
  <li><strong>Taproot Quantum Spend Paths</strong>: Proposes a quantum-safe version of Taproot that allows Bitcoin addresses to have multiple spending paths (both quantum-resistant and quantum-vulnerable), letting users continue benefiting from smaller, efficient signatures until quantum computers become a genuine threat.

  <li><strong>L402 Apps</strong>: A directory and marketplace for Lightning Network-powered applications and APIs that enable micropayments in Bitcoin. Discover apps that accept L402 payments and call verified Lightning-paywalled API endpoints priced in satoshis.

<h1 id="agenda">Agenda</h1>

<p>This month’s agenda is inspired by the lightning++ conference in Berlin that took place earlier in October. Unfortunately individual videos corresponding to specific talks have not yet been uploaded, and also any recordings of the secondary stage are not uploaded. That means that reading material remains in text form.</p>
