Reduce the number of requests to poll a Monero daemon [$800]

[erciccione]

"Currently, wallets make up to 4 requests each time a wallet polls a daemon: get_info, get_transaction_pool_hashes, get_transactions, and get_blocks.bin.

As a result, daemons must service up to 4 requests for each client poll, and the user may experience a noticeable delay before their wallet even starts to sync blocks if their connection is slow."

See the issue on the Monero repo for the full details: monero-project/monero#7571

I will make a serious attempt to implement this, over the next 3 calendar weeks or so because working on spare time.

First looks into the existing code of the RPC calls to be replaced by this single new call and their use in wallet2 and simplewalletlet me suspect that closely working together with @woodser on the exact requirements will probably be a good idea.

Thanks for the assignment!

A very first question: Where do I best place questions that I run into with this? Right here, or in some Haveno IRC / Matrix channel?

Thank you for working on this :)
The best place is #haveno-dev on IRC/Libera (#haveno-dev:haveno.network on Matrix)

Thank you very much, @woodser, for paying out that bounty! Just received it.

It was nearly 2 years ago that I took on this work, and I am grateful that the bounty was honored nevertheless. I am also glad that I could made a small contribution towards making Haveno a success.
