Demo ID: demo-2025-007 Version: [1.0.0] Last Updated: 2025-09-05

Architecture Overview

System Architecture

The system integrates a Slack bot application within BSVA’s internal Slack workspace and a Next.js-based public Q&A website.

• The Slack bot app detects emoji reactions on threaded messages to archive full threads into MongoDB.

• The public website displays shared threads and enables users to tip contributors with BSV micropayments.

• Blockchain micropayments provide economic incentives for quality participation and knowledge sharing.

Technology Stack

• Frontend: Next.js 13 (React) for the shared Q&A website

• Backend: Node.js Express server powering the Slack-bot with MongoDB for thread storage

• Database: MongoDB for persistent storage of thread metadata, messages, replies, and reactions

• Infrastructure: Hosted on cloud services with Slack API integration and BSV payment network connectivity

Key Components

1. Slack Bot App: Reacts to :inbox_tray: emoji to save and update Slack threads in MongoDB

2. Slack API Handler: Listens for real-time message updates, edits, deletions, and emoji reactions

3. Public Website: Displays threads, manages BSV micropayment tipping, and interfaces with blockchain services

Implementation Guide

Prerequisites

• Node.js (v18 or later), npm/yarn

• MongoDB instance (cloud or local)

• Slack workspace admin access for bot installation and permissions

• BSV blockchain node or provider for micropayments

Setup Instructions

Clone repositories:

Slack Threads Webapp:

git clone https://github.com/bsv-blockchain-demos/slack-threads-webapp
cd slack-threads-webapp
npm install
npm run dev

Slack Bot App:

git clone https://github.com/bsv-blockchain-demos/slack-bot-app
cd slack-bot-app
npm install
node app.js

Configuration

Key configuration parameters:

• SLACK_BOT_TOKEN: Slack bot OAuth token

• MONGO_URI: MongoDB connection string

• BSV_NODE_URL: BSV blockchain node endpoint

Testing & Validation

Test Coverage

• Unit Tests: Core Slack bot event handlers and database operations covered

• Integration Tests: Verified end-to-end thread saving, updating, and retrieval

• Performance Tests: Thread saving latency < 500ms; tipping transaction time < 2 sec

Validation Criteria

• Slack bot successfully archives threads on :inbox_tray: reaction

• Public site displays archived threads with up-to-date content

• BSV micropayment tips processed and confirmed on blockchain

Performance & Scalability

Current Metrics

• Response Time: API average 300ms

• Throughput: 50 thread saves per minute in pilot

• Resource Usage: Moderate CPU and memory usage on Node.js server

Scalability Considerations

• Potential for horizontal scaling of bot app instances

• Load balancing of API backend

• Batch processing of blockchain transactions to reduce fees and latency

Maintenance & Support

Monitoring

• Logs: Centralized logging of bot events and API requests

• Metrics: Dashboard with thread counts, tip volumes, API performance

• Alerts: Notifications for failures in thread archiving or transaction failures

Troubleshooting

Issue	Cause	Solution
Slack API rate limit	Excessive requests	Implement exponential backoff
Payment failure	Blockchain node unavailable	Retry transactions or fallback
