Decentralized Web Nodes (DWNs)

1. Introduction

Decentralized Web Nodes (DWNs) represent a fundamental shift in how we store, manage, and control personal data on the internet. They serve as personal data stores that exist within a decentralized network, giving users direct sovereignty over their digital information.

2. What are DWNs?

Decentralized Web Nodes are secure, encrypted data storage and message passing nodes that can be run anywhere. They function as personal data vaults that:

• Store both public and encrypted private data
• Process incoming messages and requests
• Execute permissions-based access control
• Synchronize data across multiple instances

3. Real-World Example

Social Media Platform Scenario

When a social media platform shuts down or enforces restrictions, traditional centralized platforms leave users with limited options. DWNs ensure data isn't tied to any single company's server.

Content Creator Use Case

Content creators facing challenges with platforms like YouTube, tiktok, Instagram, etc due to algorithm changes or policy restrictions can benefit from DWNs by having direct control over content distribution.

Personal Data Control

Users can protect their personal data from being harvested, sold, or used without consent. DWNs provide complete control over information sharing, including access permissions and duration.

4. Why Should You Care?

DWNs represent more than just technology—they're about individual empowerment. They provide:

• Control over digital identity
• Content ownership
• Enhanced privacy
• Protection against data breaches and censorship

The shift is comparable to moving from renting to owning a home in the digital space.

5. Key Features

User-Controlled Data Storage

• Users own and control their personal data stores
• Data can be hosted anywhere - cloud providers, personal servers, or edge devices
• Multiple synchronized instances provide redundancy and availability

Learn more...

Standardized Interface

• Common protocols for reading, writing, and querying data
• Standardized message passing between nodes
• Unified permissions and access control

Encryption and Security

• End-to-end encryption of private data
• Granular permissions control
• Cryptographic verification of data integrity
• Secure key management and recovery

Interoperability

• Platform-agnostic design
• Compatible with existing web standards
• Enables data portability between services

6. Benefits of DWNs

For Users

• Complete control over personal data
• Enhanced privacy and security
• Seamless data portability
• Improved service resilience

For Developers

• Simplified data management
• Reduced liability
• Standard protocols
• Interoperable systems

Technical Stack for DWNs

This technical stack provides a comprehensive overview of the components needed to build and maintain a DWN system.

For the Web

• Reduced platform lock-in
• Enhanced innovation potential
• Better privacy practices
• More resilient infrastructure

7. How DWNs Work in Everyday Life

Social Media Applications

Instead of uploading photos to Instagram's servers, images live in your DWN. Apps request access to display them.

Shopping Experience

Purchase history, preferences, and loyalty points are stored in your DWN, not scattered across different retailers' databases.

Communication Systems

Messages and emails flow through your DWN, providing true ownership of conversations.

8. Concepts of DWNs

The document emphasizes the practical implementation of DWNs as a simplified conceptual model for decentralized data management and digital sovereignty.

// DECENTRALIZED WEB NODE (DWN) - SIMPLIFIED CONCEPTUAL MODEL
// -------------------------------------------------------

// 1. CORE DATA STRUCTURE
class DWN {
    owner_did: string           // Owner's decentralized identifier
    store: {                    // Data storage
        records: Map<id, Record>
        messages: Queue<Message>
    }
    permissions: Map<schema, Rules>
    connections: Set<PeerDWN>   // Connected nodes
}

// 2. BASIC RECORD STRUCTURE
Record {
    id: unique_identifier
    schema: url                 // What kind of data this is
    data: encrypted_blob        // The actual content
    metadata: {
        created_at: timestamp
        updated_at: timestamp
        owner: did
        permissions: access_rules
        signatures: [signatures]
    }
}

// 3. CORE OPERATIONS
DWN.write(record):
    if check_permissions(record) && validate_schema(record):
        encrypt(record.data)
        sign(record)
        store(record)
        notify_peers(record)    // Sync with other nodes

DWN.read(id):
    if have_permission(id):
        record = retrieve(id)
        decrypt(record.data)
        return record
    else:
        return error("unauthorized")

// 4. SIMPLIFIED MESSAGE PROTOCOL
Message {
    type: "write" | "read" | "sync" | "auth"
    sender: did
    recipient: did
    payload: encrypted_data
    signature: sig
}

// 5. BASIC SYNC MECHANISM
on_new_record:
    for each peer in connections:
        if peer.has_permission():
            send_message(peer, {
                type: "sync",
                record: new_record
            })

// 6. PERMISSIONS EXAMPLE
permissions = {
    "schema/profile": {
        owner: [READ, WRITE, SHARE],
        friends: [READ],
        public: []
    },
    "schema/post": {
        owner: [READ, WRITE, DELETE],
        followers: [READ],
        public: [READ]
    }
}

// 7. TYPICAL USAGE FLOW
// Initialize personal DWN
my_dwn = new DWN(my_did)

// Store private data
my_dwn.write({
    schema: "schema/profile",
    data: {
        name: "Alice",
        email: "[e-mail]"
    },
    permissions: private()
})

// Share data with specific user
my_dwn.write({
    schema: "schema/message",
    data: "Hello Bob!",
    permissions: allow(bob_did)
})

// Public post
my_dwn.write({
    schema: "schema/post",
    data: "Hello World!",
    permissions: public()
})

// 8. SYNC AND REPLICATION
periodic_sync():
    peers = discover_peers()
    for peer in peers:
        diff = compare_records(peer)
        if diff:
            sync_records(diff)
            verify_sync(peer)

// 9. RECOVERY MECHANISM
backup_keys = generate_recovery_keys()
recovery_process:
    if lost_access:
        new_dwn = restore_from_peers(recovery_keys)
        verify_identity(backup_keys)
        reconstruct_permissions()
