[feature request] blockbook support (SPV alternative)

[ca333]

will be good to have https://github.com/trezor/blockbook support at some point as seems quite robust and has a bright future thanks to Trezor.

In the same spirit: https://github.com/trustwallet/blockatlas seems rly interesting

Thanks for creating the issue! It seems that we may check this during Trezor integration within the #964

@smk762 @SirSevenG We plan to start working on it in next sprint. Could you please set up the blockbook infra for the following chains before February 27? BTC, BTC testnet, Ethereum, ETH testnet (Sepolia).

@smk762 We have kmd blockbook running and synced but it's an issue to check if it works properly:

Trezor suite allows custom blockbook connection, yet does not support KMD. We probably want to setup other coins daemon to synch this week, and current server we are using for blockbook will not have enough storage space.

UPD: blockbook itself looks like it's still syncing with daemon: https://5.75.189.51:9177/API

We might want to just use public BTC/ETH node for testing blockbook, before proper production setup, what do you think?

[smk762]

Blockbook is painfully slow to sync for KMD, as mine is the first on the network. For BTC/ETH, it will be slow on the deamon sync side, but should be faster on the blockbook side. Either way, looks like this process will take weeks at least.

in the meantime, we might be able to use

• https://btc1.trezor.io/ (front end)
• https://btc1.trezor.io/api/v2/tx/bdb31013359ff66978e7a8bba987ba718a556c85c4051ddb1e83b1b36860734b (api)
• https://eth1.trezor.io/ (front end)
• https://eth1.trezor.io/api/v2/tx/0x770a946a46af5c49e579d7c71fa543bf02f1d5a23e538d0347d64cbbb162a21c (api)

these subdomains extend to btc4 & eth4
