Blossom Test Tool

A simple command-line tool to test the Blossom blob storage service by performing upload, fetch, and delete operations.

Building

# From the repository root
CGO_ENABLED=0 go build -o cmd/blossomtest/blossomtest ./cmd/blossomtest

Usage

# Basic usage with auto-generated key
./cmd/blossomtest/blossomtest

# Specify relay URL
./cmd/blossomtest/blossomtest -url http://localhost:3334

# Use a specific Nostr key (nsec format)
./cmd/blossomtest/blossomtest -nsec nsec1...

# Test with larger blob
./cmd/blossomtest/blossomtest -size 10240

# Verbose output to see HTTP requests and auth events
./cmd/blossomtest/blossomtest -v

# Test anonymous uploads (for open relays)
./cmd/blossomtest/blossomtest -no-auth

Options

• -url - Relay base URL (default: http://localhost:3334)
• -nsec - Nostr private key in nsec format (generates new key if not provided)
• -size - Size of test blob in bytes (default: 1024)
• -v - Verbose output showing HTTP requests and authentication events
• -no-auth - Skip authentication and test anonymous uploads (useful for open relays)

What It Tests

The tool performs the following operations in sequence:

1. Upload - Uploads random test data to the Blossom server

- Creates a Blossom authorization event (kind 24242) - Sends a PUT request to /blossom/upload - Verifies the returned descriptor

1. Fetch - Retrieves the uploaded blob

- Sends a GET request to /blossom/<sha256> - Verifies the data matches what was uploaded

1. Delete - Removes the blob from the server

- Creates another authorization event for deletion - Sends a DELETE request to /blossom/<sha256>

1. Verify - Confirms deletion was successful

- Attempts to fetch the blob again - Expects a 404 Not Found response

Example Output

🌸 Blossom Test Tool
===================

ℹ️  No key provided, generated new keypair
Using identity: npub1...
Relay URL: http://localhost:3334

📦 Generated 1024 bytes of random data
   SHA256: a1b2c3d4...

📤 Step 1: Uploading blob...
✅ Upload successful!
   URL: http://localhost:3334/blossom/a1b2c3d4...
   SHA256: a1b2c3d4...
   Size: 1024 bytes

📥 Step 2: Fetching blob...
✅ Fetch successful! Retrieved 1024 bytes
✅ Data verification passed - hashes match!

🗑️  Step 3: Deleting blob...
✅ Delete successful!

🔍 Step 4: Verifying deletion...
✅ Blob successfully deleted - returns 404 as expected

🎉 All tests passed! Blossom service is working correctly.

Requirements

• A running ORLY relay with Blossom enabled
• The relay must be using the Badger backend (Blossom is not available with DGraph)
• Network connectivity to the relay

Troubleshooting

"connection refused"

• Make sure your relay is running
• Check the URL is correct (default: http://localhost:3334)

"unauthorized" or "403 Forbidden"

• Check your relay's ACL settings
• If using ORLY_AUTH_TO_WRITE=true, make sure authentication is working
• Try adding your test key to ORLY_ADMINS if using follows mode

"blossom server not initialized"

• Blossom only works with the Badger backend
• Check ORLY_DB_TYPE is set to badger or not set (defaults to badger)
