Dap: A Community‑Driven Fork of the Handshake Protocol

Abstract

Dap enhances the Handshake protocol to create a more accessible and utility‑focused decentralized naming system. While Handshake laid the groundwork for blockchain‑based DNS resolution, real‑world adoption has been limited by complex registration mechanisms and misaligned incentives favoring speculation over utility. Dap addresses these limitations through streamlined name registration, enhanced security, and improved economic incentives that prioritize network stability and development over token speculation.

1. Introduction

The Domain Name System (DNS) remains one of the most centralized components of the modern internet. While Handshake introduced a compelling vision for decentralizing the DNS root zone through blockchain technology, its initial implementation revealed several limitations that have hindered widespread adoption.

Dap maintains Handshake's core mission of decentralizing internet naming while addressing key technical and practical limitations. By refining Handshake's proven foundations rather than reinventing them, Dap aims to make decentralized naming more accessible, secure, and useful for everyday internet users.

2. Background and Motivation

2.1 The Handshake Vision

Handshake was conceived as a decentralized protocol to serve as an alternative to ICANN's root zone management. Its key innovations included:

2.2 Identified Limitations

Several issues have emerged that limit Handshake's potential:

  1. Complex Name Acquisition
    • High barrier to entry for non‑technical users
    • Extended waiting periods before names become usable
    • Auction mechanism complexity
  2. Integration Challenges
    • Limited adoption by DNS providers and registrars
    • Difficult path to mainstream browser support
    • Complexity in serving DNS records
  3. Technical Constraints
    • Mining centralization concerns
    • Inefficient block space utilization
    • Limited throughput for name operations
  4. Economic Misalignment
    • Focus on speculation over utility
    • Lack of incentives for DNS infrastructure
    • Insufficient funding for ongoing development

3. Technical Implementation

3.1 Consensus Mechanism

Dap adopts RandomX as its proof‑of‑work algorithm to promote decentralized participation in network security. RandomX is specifically designed for CPUs, making mining accessible to a broader range of participants while maintaining strong security properties.

Key characteristics:

3.2 Name Registration System

The registration system implements a phased release schedule with built‑in protections against speculation and squatting:

  1. Release Phases
    
    releaseSchedule: {
      phases: [
        {
          claimWindow: "7 days",
          deposit: 1000,
          names: "Single characters, numbers",
          type: "Premium"
        },
        {
          claimWindow: "7 days",
          deposit: 500,
          names: "Two characters, dictionary words",
          type: "Standard Plus"
        },
        {
          claimWindow: "7 days",
          deposit: 100,
          names: "All remaining names",
          type: "Standard"
        }
      ]
    }
              
  2. Registration Process
    • 7‑day claim window for each phase
    • Deposit requirement based on name type
    • Multiple parties can place deposits
    • Auctions for contested names
    • 14‑day waiting period for uncontested names

3.3 Economic Model

The economic model prioritizes sustainable development and network stability over token speculation:

  1. Fee Distribution
    
    distribution: {
      community: "20%", // Grants, education, tools
      operators: "30%", // DNS infrastructure providers
      protocol: "40%",  // Core protocol development
      treasury: "10%"   // Emergency/future funding
    }
              
  2. Operator Incentives
    • Rewards based on uptime and performance
    • Geographic distribution bonuses
    • Query response time metrics
    • Record serving volume

4. Network Architecture

4.1 Node Types

The network supports three types of nodes to accommodate different use cases and resource capabilities:

  1. Full Nodes
    • Store complete blockchain
    • Validate all transactions
    • Serve DNS records
    • Participate in mining
    • Full consensus participation
  2. Light Nodes
    • Store block headers
    • Verify proofs
    • Basic DNS resolution
    • Mobile‑friendly
  3. DNS‑Only Nodes
    • Focus on DNS serving
    • Optional blockchain validation
    • High performance
    • Enhanced caching

4.2 DNS Integration

Dap maintains compatibility with existing DNS infrastructure while improving record management:


interface DNSSystem {
  // DNSSEC configuration
  dnssec: {
    algorithms: ["ECDSA", "Ed25519"],
    autoRenewal: boolean,
    keyRotation: Duration
  },
  // Standard record types
  records: {
    custom: Map<string, RecordTemplate>,
    extended: ["TLSA", "CAA", "SRV"],
    standard: ["A", "AAAA", "MX", "TXT", "CNAME"]
  },
  // Performance optimization
  serving: {
    caching: boolean,
    ttl: Duration,
    geographic: boolean
  }
}
      

5. Security Model

5.1 Threat Analysis

The security model addresses several key threats:

  1. Network Security
    • 51% attacks mitigated by RandomX
    • Sybil resistance through PoW
    • Eclipse attack protection
    • DDoS mitigation
  2. Name System Security
    • Front‑running protection through claim windows
    • Economic barriers to squatting
    • Registration phase protections
    • Dispute resolution mechanisms
  3. DNS Security
    • DNSSEC integration
    • Record tampering protection
    • Cache poisoning prevention
    • MitM attack mitigation

5.2 Economic Security

Economic mechanisms protect against abuse while ensuring sustainable development:


interface SecurityMechanisms {
  registration: {
    // Auction mechanics
    auctions: {
      extensionTime: "1 day",
      minBidIncrease: "10%",
      minDuration: "3 days"
    },
    // Claim window deposits
    deposits: {
      lockPeriod: "30 days",
      minimums: Map<NameType, Amount>,
      returnPeriod: "7 days"
    }
  },
  operations: {
    // Infrastructure incentives
    rewards: {
      distribution: "20%",
      performance: "30%",
      records: "20%",
      uptime: "30%"
    }
  }
}
