DNS Discovery true learn

Built upon the foundation of EIP-1459: Node Discovery via DNS, DNS Discovery allows the retrieval of an ENR tree from the TXT field of a domain name. This innovative approach enables the storage of essential node connection details, including IP, port, and multiaddr.

This bootstrapping method allows anyone to register and publish a domain name for the network, promoting increased decentralisation.

Pros

  • Low latency, low resource requirements.
  • Easy bootstrap list updates by modifying the domain name, eliminating the need for code changes.
  • Ability to reference a larger list of nodes by including other domain names in the code or ENR tree.

Cons

  • Vulnerable to censorship: Domain names can be blocked or restricted.
  • Limited scalability: The listed nodes are at risk of being overwhelmed by receiving all queries. Also, operators must provide their ENR to the domain owner for listing.
