Mini Validate Database

A secure and transparent blockchain-based system for tracking digital assets with privacy controls, valuation history, and monitoring capabilities.

Overview

VaultPulse Asset Tracker enables users to:

• Register and categorize digital assets
• Track asset valuations over time
• Set monitoring thresholds for asset values
• Control privacy settings and authorized viewers
• Maintain immutable records for compliance and reporting
• Generate asset performance analytics

Architecture

The system is built around the concept of user vaults that contain digital assets. Each vault can hold multiple assets, with comprehensive tracking of valuations and customizable monitoring thresholds.

Core Components:

• Vaults: Container for a user's portfolio with privacy settings
• Assets: Individual digital assets with metadata and current valuation
• History: Immutable record of asset valuations over time
• Categories: User-defined asset classifications
• Thresholds: Monitoring rules for asset values
• Access Control: Granular permissions for vault viewers

Contract Documentation

Main Contract: data-validator.clar

The primary contract that manages database validation and record tracking.

Key Data Structures:

• assets: Stores record details and metadata
• asset-history: Tracks record modification history
• user-categories: Custom record categorization
• vaults: User database metadata
• authorized-viewers: Access control for third parties
• monitoring-thresholds: Validation rule monitoring

Getting Started

Prerequisites

• Clarinet CLI
• Stacks wallet for deployment

Basic Usage

1. Initialize a database vault:

(contract-call? .data-validator set-category "finance" u"Financial Records" (some u"Sensitive financial data management"))

2. Register a new record:

(contract-call? .data-validator register-asset 
    "record001" 
    u"Customer Financial Profile" 
    "finance" 
    u1635724800 
    u0 
    u1 
    (some u"Compliance-related record") 
    false)

3. Update record status:

(contract-call? .data-validator update-asset-value "record001" u2)

Function Reference

Asset Management

register-asset

(register-asset 
    (asset-id (string-ascii 36))
    (name (string-utf8 100))
    (category (string-ascii 50))
    (acquisition-date uint)
    (acquisition-cost uint)
    (current-value uint)
    (metadata (optional (string-utf8 1000)))
    (public-view bool))

update-asset-value

(update-asset-value (asset-id (string-ascii 36)) (new-value uint))

Access Control

authorize-viewer

(authorize-viewer (viewer principal) (expiration (optional uint)))

revoke-viewer

(revoke-viewer (viewer principal))

Monitoring

set-threshold

(set-threshold
    (asset-id (string-ascii 36))
    (threshold-id (string-ascii 36))
    (comparison (string-ascii 2))
    (value uint)
    (description (optional (string-utf8 200))))

Development

Local Testing

1. Initialize project:

clarinet new mini-validate-database

2. Run tests:

clarinet test

3. Start local chain:

clarinet console

Security Considerations

Access Control

• All asset operations require owner authentication
• Viewer access can be time-limited
• Public visibility is configurable per asset

Data Privacy

• Asset details are only visible to authorized parties
• Historical records are immutable once created
• Metadata can be optionally included or excluded

Limitations

• No support for fractional ownership
• Asset values must be represented as integers
• Threshold monitoring requires external triggers

Best Practices

• Regularly review authorized viewers
• Set expiration dates for temporary access
• Keep sensitive details in metadata optional
• Validate all inputs before transactions
