Blockscout: Add support for Goerli Testnet

[GregTheGreek]

Describe your issue here.
Currently blockscout does support the Goerli testnet. I will be working to have a configuration for the goerli tesnet setup for this weekend.

Not sure if it has been started, don't want to replicate work, but I don't think this will take long after looking at the code and getting help from #1110

[acravenho]

Please let me know if you need help during the process. I'll be available all weekend.

[GregTheGreek]

@acravenho Thanks!

I have one question right now, on the UI where does the navbar live and where does the dropdown tab live so I can add Goerli as an option there for starters and then I'll pass the flag downward

[acravenho]

@GregTheGreek

Here is the location of the navbar: https://github.com/poanetwork/blockscout/blob/cc266dd72828c7efedafc19f18c4ccd3d302ebb1/apps/block_scout_web/lib/block_scout_web/templates/layout/_topnav.html.eex#L105

I just want to make sure we're on the same page. Would you like us to host Goerli on BlockScout.com? If so, I can handle making all the necessary changes.

[GregTheGreek]

@acravenho You know what I think that makes more sense! If you guys can do that, it would be awesome. I was just going to host it myself but if you are ok doing it that would be awesome :)

@GregTheGreek , I was talking to @5chdn earlier and thats what we assumed would be happening.

@acravenho here are the front-end colours supplied by Afri

- Rosy Brown #AFA392
- Dim Gray #4A443A
- Black #20201A
- Gray #766F65

Logo below

@GregTheGreek , please let me know if the above is fine :-)

[acravenho]

@SiddigZeidan How do you feel about the colors and logo?

[SiddigZeidan]

Looks good to me! Lets wait to see what @GregTheGreek and @5chdn think.

[acravenho]

Please be aware that we are working on a different graph/layout for Testnets that does not include a price graph.

[GregTheGreek]

@SiddigZeidan @acravenho Looks good to me, great work guys! @5chdn thoughts?

[GregTheGreek]

@acravenho Let me know if you have any troubles connecting to peers or setting up the goerli chain

[acravenho]

@GregTheGreek We launched a full Geth node but it seems pretty fragile right now. Would you recommend Geth, Parity, or Parity Clique?

[GregTheGreek]

@acravenho We're running geth nodes and don't seem to be having any issues (@5chdn may tell you otherwise ;) hahah). What seems to be the issue you're running into? Perhaps jump into the gitter channel https://gitter.im/goerli/testnet.

@acravenho

• Design is fantastic. If you need more contrast, play around with Khaki #F0D96B.
• The most stable client, for now, is Geth if you inject bootnodes correctly. Or just run this branch which comes with built-in nodes: https://github.com/ethereum/go-ethereum/pull/18121
• Very experimental client is https://github.com/goerli/parity-goerli which is far from finished but should work if you want Parity experience (TL;DR syncs the chain and has all Parity features)

Looks amazing @SiddigZeidan & @acravenho :)

Thanks for supporting the Görli testnet!

[acravenho]

Now live at https://blockscout.com/eth/goerli :tada:

[GregTheGreek]

Amazing work everyone :)

[ChainSafeSystems]

Hey @acravenho & @SiddigZeidan, I noticed something minor today. When trying to navigate from one of the other testnets to Görli it is not visible in the drop down.

[acravenho]

Hi @ChainSafe ,
On my next deploy to these other networks, Görli will be included in the dropdown for all networks. This will most likely occur on Wednesday.

[ChainSafeSystems]

Awesome thanks @acravenho :)
