Unstoppable Domains IPFS for local gateway should show ipfs://

[bbondy]

When Unstoppable Domains is set to resolve via Ethereum, and the local gateway is in use, we resolve to an IPFS URI like:
http://bafybeihihoci7ocqupvuda3ldpiy5zvjctgybg32jxpppplkstdwtq7dhi.ipfs.localhost:48081/

Instead we should show ipfs:// in that case.

How does Ethereum resolution work? If it is using https://resolver.unstoppable.io/dns-query or https://eth.resolver.cloudflare-eth.com/dns-query then we will be able to keep ipns:// when go-ipfs 0.9.0 ships (#15749 (comment))

@lidel Currently it calls Unstoppable Domains smart contract via eth_call when visiting *.crypto, if there's IPFS content hash record existed, we'll redirect to ipfs://{CID} using that.

[lidel]

@yrliou is Brave running own Ethereum light client, or is the eth_call delegated to some infra in the cloud?

[yrliou]

@lidel currently we do eth_call via Infura.

[lidel]

Ack. In that case we need to wait for go-ipfs 0.9.0, and we will be able to show ipns://*.crypto

UD set as Ethereum, ipfs as local node:

• 0.7.0 shows DNS error for me when I navigate to "brad.crypto"
• 0.9.0-rc1 navigates to http://bafybeihihoci7ocqupvuda3ldpiy5zvjctgybg32jxpppplkstdwtq7dhi.ipfs.localhost:48081/

[lidel]

We should start work towards supporting .crypto over DoH resolver in 0.9.0+
UX is better, and you don't decrease security in any way (resolution is delegated to a third party in both cases, but using DoH for name resolution keeps ipns://brad.crypto in address bar.

about the DNS error with 0.7.0, it works fine on another computer and navigates me to ipfs://bafybeihihoci7ocqupvuda3ldpiy5zvjctgybg32jxpppplkstdwtq7dhi/ (brad.crypto + UD set as Ethereum + ipfs as local node) @lidel @bbondy

Note that the behavior with 0.7.0 is pointing the user at a static snapshot – the user may not understand this is an immutable version, and if they bookmark ipfs:// URI they will get stuck with this version of the website forever.
