explorer: add ANS domain names to account details and enable searching by domain names

[tonivlad]

Problem

Add ANS (Alternative Name Service) by Onsol Labs domain name support to the Explorer

• enable searching by ANS domains
• enable showing domains owned by an address

ANS is a protocol similar to Bonfida's SNS (.sol) that enables any project on Solana to have their own TLD ( .anything ) with a few extra features like

• it's written in anchor
• domains can be expirable ( people own them for a limited amount of time, after which they need to renew them, like .eth )
• realloc

We're starting with a few communities/projects to enable TLDs for them before going public with the protocol.

The process to create a new TLD is first come first serve but currently involves talking to us, because we are trying to filter the first projects to make sure they are they are projects that have stood the test of time and have a long term plan. We're doing this also because we want to see what other features they require.

we're currently in talks with:

• MonkeDAO for .monke
• ThugDAO for .thug
• Frakt for .frakt and a few other projects

also talking with

• Matrica to enable Discord gating through domain ownership
• Solana.fm to enable owned domains list
• Helius Labs for domain indexing
• Brave browser to enable sending to ANS domains in their wallet
• Ultimate Finance wallet to enable sending to ANS domins and a few other projects

We are already included in Dialect's sdk to enable sending messages to our domains https://github.com/dialectlabs/sdk/

To make all this happen we wrote three programs:

1. ANS - alternative name service
2. TldHouse - enables creation and management of the TLDs through the ANS let's a project (TLD owner) chose to let the community claim domains using
   • any SPL token
   • SOL
   • only owners of a certain NFT collection can claim/buy a domain
3. NameHouse - domain NFT wrapping/unwrapping to enable trading on any NFT marketplace

Onsol Labs is currently self funded/bootstrapped but we applied for a grant from Solana Foundation both through the normal channel and the MonkeDao initiative.

Being included in the Solana Explorer would help a lot with our other integration efforts.

The long term plan for the protocol is to go decentralised - a good example what we have in mind is ENS on Ethereum.

Thank you for explaining your contracts! We want to allow ecosystem projects to add their own annotations and (to some extent) UI for their smart contracts in the new year. We will explain how we plan on doing this in a separate issue in the new year.

Hey thank you for bringing this up. We're not considering changes to the explorer UI that prioritize one protocol over another right now. However, we would love to support this as much as we can through the framework proposed here: https://github.com/solana-labs/explorer/issues/196

If you have a proposal on how to handle searching for programs, more generally than just for ANS name extensions, let us know :)
