## Issue Addressed #3804 ## Proposed Changes - Add `total_balance` to the validator monitor and adjust the number of historical epochs which are cached. - Allow certain values in the cache to be served out via the HTTP API without requiring a state read. ## Usage ``` curl -X POST "http://localhost:5052/lighthouse/ui/validator_info" -d '{"indices": [0]}' -H "Content-Type: application/json" | jq ``` ``` { "data": { "validators": { "0": { "info": [ { "epoch": 172981, "total_balance": 36566388519 }, ... { "epoch": 172990, "total_balance": 36566496513 } ] }, "1": { "info": [ { "epoch": 172981, "total_balance": 36355797968 }, ... { "epoch": 172990, "total_balance": 36355905962 } ] } } } } ``` ## Additional Info This requires no historical states to operate which mean it will still function on the freshly checkpoint synced node, however because of this, the values will populate each epoch (up to a maximum of 10 entries). Another benefit of this method, is that we can easily cache any other values which would normally require a state read and serve them via the same endpoint. However, we would need be cautious about not overly increasing block processing time by caching values from complex computations. This also caches some of the validator metrics directly, rather than pulling them from the Prometheus metrics when the API is called. This means when the validator count exceeds the individual monitor threshold, the cached values will still be available. Co-authored-by: Paul Hauner <paul@paulhauner.com> |

Lighthouse: Ethereum consensus client
An open-source Ethereum consensus client, written in Rust and maintained by Sigma Prime.
Overview
Lighthouse is:
- Ready for use on Ethereum consensus mainnet.
- Fully open-source, licensed under Apache 2.0.
- Security-focused. Fuzzing techniques have been continuously applied and several external security reviews have been performed.
- Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
- Funded by various organisations, including Sigma Prime, the Ethereum Foundation, ConsenSys, the Decentralization Foundation and private individuals.
- Actively involved in the specification and security analysis of the Ethereum proof-of-stake consensus specification.
Staking Deposit Contract
