[EIP-3030]: https://eips.ethereum.org/EIPS/eip-3030 [Web3Signer]: https://consensys.github.io/web3signer/web3signer-eth2.html ## Issue Addressed Resolves #2498 ## Proposed Changes Allows the VC to call out to a [Web3Signer] remote signer to obtain signatures. ## Additional Info ### Making Signing Functions `async` To allow remote signing, I needed to make all the signing functions `async`. This caused a bit of noise where I had to convert iterators into `for` loops. In `duties_service.rs` there was a particularly tricky case where we couldn't hold a write-lock across an `await`, so I had to first take a read-lock, then grab a write-lock. ### Move Signing from Core Executor Whilst implementing this feature, I noticed that we signing was happening on the core tokio executor. I suspect this was causing the executor to temporarily lock and occasionally trigger some HTTP timeouts (and potentially SQL pool timeouts, but I can't verify this). Since moving all signing into blocking tokio tasks, I noticed a distinct drop in the "atttestations_http_get" metric on a Prater node:  I think this graph indicates that freeing the core executor allows the VC to operate more smoothly. ### Refactor TaskExecutor I noticed that the `TaskExecutor::spawn_blocking_handle` function would fail to spawn tasks if it were unable to obtain handles to some metrics (this can happen if the same metric is defined twice). It seemed that a more sensible approach would be to keep spawning tasks, but without metrics. To that end, I refactored the function so that it would still function without metrics. There are no other changes made. ## TODO - [x] Restructure to support multiple signing methods. - [x] Add calls to remote signer from VC. - [x] Documentation - [x] Test all endpoints - [x] Test HTTPS certificate - [x] Allow adding remote signer validators via the API - [x] Add Altair support via [21.8.1-rc1](https://github.com/ConsenSys/web3signer/releases/tag/21.8.1-rc1) - [x] Create issue to start using latest version of web3signer. (See #2570) ## Notes - ~~Web3Signer doesn't yet support the Altair fork for Prater. See https://github.com/ConsenSys/web3signer/issues/423.~~ - ~~There is not yet a release of Web3Signer which supports Altair blocks. See https://github.com/ConsenSys/web3signer/issues/391.~~
