It seems that the intro from the blog was better

Round Robin -> Leader Election everythere
| Round Robin algorithm defines how the order of validating nodes for the | ||
| height `H` should be calculated. Such order determines node's `block | ||
| proposal` priority. That is, block proposal from node #2 would be | ||
| accepted only if `block proposal` from node #1 was absent. ## Algorithm |
| selection. To remove any centrality point, Exonum needs make block | ||
| generation distibuted. The proposed algorithm is revealed here. | ||

Solvable problem or problems?
This section is also better written in blog
| Due to this property, byzantine nodes would not follow one after the | ||
| other in a series but would be randomly interspersed with fair nodes. | ||

Is it really the implemented algorithm from Exonum?

It is rather surprising to see properties before the algorithm description

Review as of adc3e00. The text should be restructured as follows:
- Short intro
- Description of what is actually accomplished in Exonum Core and how it can be configured/extended
- Motivation: why is the leader election algorithm needed and what security properties it yields
- Maybe, unsolved problems iff we will solve them
