We're excited to propose the Ideal Network (IDN), a foundational randomness infrastructure for Polkadot's ecosystem. Our team, formed during the Polkadot Blockchain Academy in Buenos Aires, includes Juan Girini (former Parity FRAME Core Engineer), Tony Riemer (Lead Protocol Engineer), Carlos Montoya (Serial Entrepreneur), and Coleman Irby (Software Engineer).

<h2 id="theproblem">The Problem</h2>
Polkadot lacks a comprehensive verifiable randomness solution, with several key limitations in the ecosystem:
<ul>
<li>Block Hash Limitations:
<ul>
<li>Proven security vulnerabilities (e.g. $150M <a href="https://www.apriorit.com/dev-blog/556-fomo3d-vulnerability">Fomo3D</a> exploit)</li>
<li><a href="https://owasp.org/www-project-smart-contract-top-10/">OWASP</a> top 10 smart contract vulnerability</li>
<li>Vulnerable to block producer manipulation</li>
<li>Widely used despite known risks</li>
</ul>
</li>
<li>VRF Implementation Issues:
<ul>
<li>High complexity and lack of standardization</li>
<li>Vulnerable to block author manipulation</li>
<li>Requires complex multi-collator coordination</li>
</ul>
</li>
<li>BABE VRF Constraints:
<ul>
<li>Limited to 4-hour block producer selection cycles</li>
<li>Long delays between generation and availability</li>
<li>Manipulation risks</li>
</ul>
</li>
<li>System Barriers:
<ul>
<li><a href="https://docs.chain.link/vrf/v2/estimating-costs">High costs</a> and implementation overhead</li>
<li>Significant latency issues</li>
<li>Poor cross-parachain compatibility</li>
</ul>
</li>
<li>Missing Timelock Features:
<ul>
<li>No built-in future randomness encryption</li>
<li>Limited support for commit-reveal protocols</li>
<li>Inadequate trustless multi-party coordination</li>
</ul>
</li>
</ul>
<h2 id="oursolution">Our Solution</h2>
IDN will serve as the standardized randomness layer for Polkadot's World Computer by providing:
<ul>
<li>A trustless bridge to Drand's distributed randomness beacon</li>
<li>Timelock encryption capabilities</li>
<li>Subscription-based and on-demand randomness delivery</li>
<li>Smart contract integration through ink!</li>
<li>Pallet integration for runtimes</li>
</ul>
<h2 id="traction">Traction</h2>
Our work is supported through collaborations with Web3 Foundation, <a href="https://csrc.nist.gov/Projects/interoperable-randomness-beacons">NIST</a>, and the <a href="https://random.colorado.edu/">University of Colorado</a>. We've completed a <a href="https://github.com/w3f/Grants-Program/blob/master/applications/cryptex.md">Web3 Foundation grant</a>, participated in the <a href="https://medium.com/web3foundation/decentralized-futures-introducing-etf-network-cd8282be6143">Decentralized Futures program</a>, and received retroactive funding from the <a href="https://kusama.polkassembly.io/referenda/442">Kusama treasury</a>.
