Simple DoH Server for Blockchain Domains

This is a simple DoH server for blockchain domains. Currently, it can support the following blockchain domains:

• .sol - Solana Name Service
• .fc - Farcaster username's URL field
• .bit

Usage

Start a local instance:

FLASK_DEBUG=true flask run --host=0.0.0.0

Look up a .sol domain:

curl -H "accept: application/dns-json" -X GET "http://127.0.0.1:5000/dns-query?name=ohlife.sol"

Look up a .bit domain:

curl -H "accept: application/dns-json" -X GET "https://dweb-dns.v2ex.pro/dns-query?name=v2ex.bit"

Usage with Kubo (go-ipfs)

You can use this server with Kubo by adding the following to your config:

"DNS": {
  "Resolvers": {
    "bit.": "https://dweb-dns.v2ex.pro/dns-query",
    "sol.": "https://dweb-dns.v2ex.pro/dns-query"
  }
}

After that, your Kubo gateway will be able to resolve and access blockchain domains like this:

• https://ipfs.v2ex.pro/ipns/planetable.sol/
• https://ipfs.v2ex.pro/ipns/v2ex.bit/
• https://ipfs.v2ex.pro/ipns/planetable.bit/

With the IPFS support in Brave, you can access blockchain domains like this:
