Satscribe is a web application that transforms Bitcoin blocks and transactions into insightful, human-readable conversations.

Enter a transaction ID , block hash, or block height. The app fetches the blockchain data via the Blockstream API and generates a plain-language explanation using OpenAI. Each chat is stored, so you can revisit or share it anytime.

Satscribe doesn’t require user accounts or passwords. Instead, it leverages the Nostr protocol to establish ownership of chats in a decentralized, privacy-friendly way.

• 🔎 Search the blockchain by txID, block hash or height
• 🤖 Chat-powered summaries using GPT-4o
• 🌐 Fetches data from Blockstream and CoinGecko
• 💬 Ask follow-up questions and pick a persona (Educator, Developer, Storyteller)
• 💾 Chats are saved and can be shared or kept private
• 📈 Shows the latest block height and BTC price
• ⚡️ Lightning tipping after the free quota is reached
• 🗂️ View and search your previous chats
• 🔐 Login via Nostr

• PHP 8.2+
• Composer
• Node.js 20+ and npm
• SQLite
• Laravel 12.x
• OpenAI API Key

git clone https://github.com/Chemaclass/satscribe.git
cd satscribe

composer install
npm install
cp .env.example .env
php artisan key:generate

Then configure your .env

DB_CONNECTION=sqlite

OPENAI_API_KEY=sk-...
OPENAI_MODEL=gpt-4o

And migrate the DB:

php artisan migrate

Run the app for local development:

composer dev

Once the server is running, open http://localhost:8000 and start a chat by entering a TXID, block hash or height. The assistant summarizes the data, and you can ask follow-up questions. All chats are stored and listed on the History page.

If your browser doesn't have a Nostr extension, you can still sign in with your private key or generate a new priv/public key to be temp stored in your local storage – more about it here.

Run the automated test suite with:

composer fix && composer test
