[Feature] #3 - Validator reports and insights

[kukabi]

User story

As a user, I want to be able to view various reports about a validator's performance, so that if it is one of my validators I can get insights on the functioning of it, or otherwise I can analyze the information for comparison with my validator(s).

Feature Details

Figure 3.1 Browsing into validator reports.

Single era report - available for any selected era in which the selected validator was active:

• Era points.
• Elected stake, active and inactive nominators.
• Income from commission and self-stake.
• Total rewards distributed, and reward per nominator.
• Produced block count and block numbers.
• Performance compared to other validators.
• Commission.
• Faults.
• Slashes.
• Chillings.

Validator reports over eras:

• Inclusion.
• Era points.
• Income.
• Total rewards distributed.
• Block count.
• Commission.
• Performance (?.)
• Faults.
• Slashes.
• Chillings.
• Return rate percentage.

Program-specific reports - eg 1KV for Kusama and Polkadot:

• Rank.
• Score.

Insights

Although not very clear at the moment in terms of specifications, SubVT should do more than just displaying whatever data available on- or off-chain, and it should also analyze possible correlations/causations in the data and provide insights about:

• Nominator loyalty, what it could be related to and how to improve it.
• Observations on the top-performing nodes.
• What on- and off-chain metrics could be affecting the node's performance and profitability?

These insights could be utilized in creating a future SubVT rating, and the app could make suggestions about what measures the node operators can take to increase their validators' performance.
