Seed Hypermedia (SHM) is a decentralized publishing system where:

• You own your identity (cryptographic keys, not usernames)

• Content is signed and verifiable

• Documents sync peer-to-peer across the network

• No central server can delete or censor your content

The daemon runs locally, manages your keys, signs documents, and syncs with the network.

Download the Seed daemon for your platform from the official releases, or build from source:

# Clone the repo
git clone https://github.com/seed-hypermedia/seed
cd seed

# Build the daemon
go build -o seed-daemon ./backend/cmd/seed-daemon

# Or download pre-built binary from releases

For headless/server environments (no GUI keyring):

SEED_FILE_KEYSTORE=1 ./seed-daemon -data-dir ~/.seed-daemon

The daemon exposes:

• Port 55001: HTTP API (file uploads, web interface)

• Port 55002: gRPC API (document operations)

Generate a new key (your identity):

grpcurl -plaintext -d '{
  "name": "mykey"
}' localhost:55002 com.seed.daemon.v1alpha.Daemon/GenMnemonic

# SAVE THE MNEMONIC! It's your recovery phrase.

Register the key:

grpcurl -plaintext -d '{
  "name": "mykey",
  "mnemonic": "your twelve word mnemonic phrase here ..."
}' localhost:55002 com.seed.daemon.v1alpha.Daemon/RegisterKey

This gives you an account ID like z6MkvYf14wnNbjyxwV4rt9D6tNQ5fc8ZaUk4ucJn4mYLpCD6

grpcurl -plaintext -d '{
  "account": "YOUR_ACCOUNT_ID",
  "path": "/hello-world",
  "signingKeyName": "mykey",
  "changes": [
    {"set_metadata": {"key": "name", "value": "Hello World"}},
    {"replace_block": {
      "id": "p1",
      "type": "Paragraph",
      "text": "My first Seed Hypermedia document!"
    }},
    {"move_block": {"block_id": "p1", "parent": "", "left_sibling": ""}}
  ]
}' localhost:55002 com.seed.documents.v3alpha.Documents/CreateDocumentChange

Congratulations! Your document is now signed and stored locally.

Push to a gateway so others can see it:

grpcurl -plaintext -d '{
  "addrs": ["/p2p/12D3KooWEDdEeuY3oHCSKtn1eC7tU9qNWjF9bb8sCtHzpuCjvomQ"],
  "resources": ["hm://YOUR_ACCOUNT_ID/hello-world"],
  "recursive": true
}' localhost:55002 com.seed.documents.v3alpha.Resources/PushResourcesToPeer
