<h2>
  
  
  TL;DR
</h2>

<h3>
  
  
  DeDe is a minimal, Ethereum-based protocol for physical delivery.
</h3>

<p>No apps, no marketplace, no routing engine, only trustless escrow and deterministic settlement.<br>
It lets anyone build P2P delivery networks without central control or intermediaries.</p>




<h3>
  
  
  Why this matters in Brazil
</h3>

<p><strong>Brazil has one of the most active P2P commerce ecosystems in the world, powered by Pix.</strong><br>
Pix enables instant payment, but it does not provide trustless escrow or delivery confirmation.</p>

<p>DeDe fills this gap by offering a neutral, programmable settlement layer for physical delivery, independent of platforms or intermediaries.</p>

<ul>
<li>DeDe Protocol is a minimal, self-contained, production-ready settlement layer for decentralized delivery networks.</li>
<li>Peer-to-Peer Parcel -&gt; Pickup -&gt; Dropoff -&gt; Delivery confirmation.</li>
<li>DeFi/CeFi Agnostic: Easy integration of delivery settlement for apps, fintech providers, and payment platforms within existing workflows.</li>
</ul>




<h3>
  
  
  Motivation
</h3>

<p>We have decentralized infrastructure for:</p>

<ul>
<li>    Money (Bitcoin)</li>
<li>    Communication (Matrix)</li>
<li>    Compute (Ethereum)</li>
<li>    Privacy (Tor)</li>
</ul>

<p>But physical delivery still a key part of human coordination remains centralized, fragile, and opaque.</p>

<p>Postal systems are slow, expensive, often fail to deliver, and structurally incompatible with privacy.<br>
Meanwhile, enormous underutilized capacity exists in everyday human movement:<br>
people walk, bike, drive, and commute along routes that could carry parcels.</p>

<p>DeDe lets anyone tap into that movement.<br>
It enables real-world delivery as a trustless, peer-to-peer settlement flow, not a logistics monopoly.</p>

<p><strong>Sender → Escrow → Carrier Pickup → Dropoff → Finalize → Settlement</strong></p>




<h3>
  
  
  What It Is
</h3>

<p><strong>DeDe is not an app, not a marketplace, and not a company.</strong><br>
It is a small Ethereum smart contract protocol that allows:</p>

<ul>
<li>    Senders to register a parcel NFT + escrow</li>
<li>    Carriers to voluntarily pick it up</li>
<li>    Delivery to be confirmed (opt-in)</li>
<li>    Settlement to be finalized without trusted intermediaries</li>
</ul>

<p><strong>The protocol governs:</strong></p>

<ul>
<li>    Who gets paid</li>
<li>    Under what conditions</li>
<li>    How funds are held and released</li>
<li>    Immutable protocol fee routing</li>
<li>    Minimal incentive alignment</li>
</ul>

<p>All logistics, routing, and app-specific behavior happens off-chain.<br>
Architecture</p>




<h3>
  
  
  Core contracts:
</h3>

<ol>
<li><strong>ParcelCore</strong></li>
</ol>

<ul>
<li>    ERC-721 parcels with deterministic lifecycle states</li>
<li>    Immutable protocol fee (e.g. 0.5%)</li>
<li>    Support for platform-level BPS fee schedules</li>
<li>    Finalization window (e.g. 72h after pickup)</li>
</ul>

<ol>
<li><strong>Escrow</strong></li>
</ol>

<ul>
<li>    Holds ETH/ERC-20 funds keyed by parcelId</li>
<li>    Releases funds to carrier, protocol treasury, platform treasury,   and finalizer tip</li>
<li>    Enforces deterministic payout logic</li>
</ul>

<ol>
<li><strong>AStarSignerRegistryStaked</strong></li>
</ol>

<ul>
<li>    (Optional) registers routing signers with stake</li>
<li>    Ties dropoff event to a verifiable off-chain route hash</li>
<li>    Allows eventual zkRoute integrations</li>
</ul>

<p>All state transitions are public and auditable.<br>
DeDe does not include any GPS, KYC, login systems, or metadata on-chain.</p>

<h3>
  
  
  On-chain Privacy Model
</h3>

<ul>
<li>    On-chain: only tokenId, state enum, and lifecycle timestamps</li>
<li>    Off-chain: pickup/dropoff locations, photo proofs, routing paths</li>
<li>    Metadata is stored in NFT, encrypted, or referenced via IPFS 
hashes
Ethereum only sees a hash</li>
</ul>




<h3>
  
  
  What Makes DeDe Unique
</h3>

<ul>
<li>    It’s a protocol, not a platform</li>
<li>    No centralized operator, job board, or trusted intermediary</li>
<li>    Anyone can build an app, mint a parcel, or pick one up</li>
<li>    Payments settle only if both sides confirm (or finalize automatically)</li>
<li>    Protocol fee is immutable, finalizer tip is capped, all logic is deterministic</li>
</ul>

<p>No pricing engine.<br>
No identity layer.<br>
No assignment logic.<br>
Just neutral rails.</p>

<h3>
  
  
  Use Cases
</h3>

<ul>
<li>    P2P delivery during commutes (side income for regular people)</li>
<li>    Local business delivery without contracts or apps</li>
<li>    Decentralized logistics experiments (DAOs, disaster relief, rural mobility)</li>
<li>    Trust-minimized gig networks in low-trust regions</li>
</ul>

<h3>
  
  
  Economics
</h3>

<ul>
<li>    Protocol fee: immutable (e.g. 0.5%)</li>
<li>    Platform fee: configurable, set by each integrator</li>
<li>    Finalizer tip: small % (e.g. 0.05%), capped</li>
<li>    DeDe does not reduce escrow value over time (no built-in decay)</li>
<li>    Settlement is voluntary; payment is conditional on mutual confirmation</li>
</ul>




<h3>
  
  
  Why Ethereum?
</h3>

<p>DeDe works best when:</p>

<ul>
<li>    The settlement layer is public, neutral, auditable</li>
<li>    Applications are permissionless and forkable</li>
<li>    The infrastructure isn’t subject to any central actor’s control</li>
</ul>

Abstract: Understanding a complicated Ethereum transaction remains challenging: multi-hop token flows, nested contract calls, and opaque execution paths routinely lead users to blind signing. Based on interviews with everyday users, developers, and auditors, we identify the need for faithful, step-wise explanations grounded in both on-chain evidence and real-world protocol semantics. To meet this need, we introduce (matex, a cognitive multi-agent framework that models transaction understanding as a collaborative investigation-combining rapid hypothesis generation, dynamic off-chain knowledge retrieval, evidence-aware synthesis, and adversarial validation to produce faithful explanations.

تم تقديم إطار عمل متعدد الوكلاء جديد يسمى matex لتحسين فهم معاملات Ethereum، حيث يتناول التحديات مثل تدفقات الرموز متعددة القفزات واستدعاءات العقود المتداخلة. يهدف هذا الإطار إلى تقديم تفسيرات خطوة بخطوة تستند إلى كل من الأدلة على السلسلة ودلالات البروتوكولات في العالم الحقيقي، كما تم تحديده من خلال مقابلات مع المستخدمين والمطورين والمدققين.

Abstract: Bitcoin mining hardware acquisition requires strategic timing due to volatile markets, rapid technological obsolescence, and protocol-driven revenue cycles. Despite mining's evolution into a capital-intensive industry, there is little guidance on when to purchase new Application-Specific Integrated Circuit (ASIC) hardware, and no prior computational frameworks address this decision problem. We address this gap by formulating hardware acquisition as a time series classification task, predicting whether purchasing ASIC machines yields profitable (Return on Investment (ROI) >= 1), marginal (0 < ROI < 1), or unprofitable (ROI <= 0) returns within one year. We propose MineROI-Net, an open source Transformer-based architecture designed to capture multi-scale temporal patterns in mining profitability. Evaluated on data from 20 ASIC miners released between 2015 and 2024 across diverse market regimes, MineROI-Net outperforms LSTM-based and TSLANet baselines, achieving 83.7% accuracy and 83.1% macro F1-score. The model demonstrates strong economic relevance, achieving 93.6% precision in detecting unprofitable periods and 98.5% precision for profitable ones, while avoiding misclassification of profitable scenarios as unprofitable and vice versa. These results indicate that MineROI-Net offers a practical, data-driven tool for timing mining hardware acquisitions, potentially reducing financial risk in capital-intensive mining operations. The model is available through: https://github.com/AMAAI-Lab/MineROI-Net.

تم تطوير إطار عمل جديد يسمى MineROI-Net للتنبؤ بالعائد على الاستثمار (ROI) لمعدات تعدين البيتكوين، مما يعالج التحديات التي تطرحها تقلبات السوق والتغيرات التكنولوجية السريعة. يصنف هذا النموذج القائم على التعلم العميق عمليات شراء أجهزة ASIC المحتملة إلى فئات مربحة أو هامشية أو غير مربحة، بناءً على بيانات تاريخية من 20 جهاز تعدين تم إصدارها بين عامي 2015 و2024.

Se ha desarrollado un nuevo marco llamado MineROI-Net para predecir el retorno de la inversión (ROI) en hardware de minería de Bitcoin, abordando los desafíos planteados por la volatilidad del mercado y los rápidos cambios tecnológicos.
