-- Conclusion: probability of being selected as the block proposer from the shuffled consolidated validator set of size n is the same for each validator, regardless of the extent of consolidation

-- However, there are other considerations for a staker to take into account when deciding on a consolidation strategy, such as compounding, rewards earned, slashing risk, and penalties that vary with effective balance

5. Detecting smart contract attacks via invariant mining (source)

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
