Special thanks to Jinglan Wang for review and feedback One question that often comes up is: how exactly is sharding different from sidechains or Plasma? All three architectures seem to involve a hub-and-spoke architecture with a central “main chain” that serves as the consensus backbone of the system, and a set of “child” chains containing actual user-level transactions.

Coin holder voting, both for governance of technical features, and for more extensive use cases like deciding who runs validator nodes and who receives money from development bounty funds, is unfortunately continuing to be popular, and so it seems worthwhile for me to write another post explaining why I (and Vlad Zamfir and others) do not consider it wise for Ethereum (or really, any base-layer blockchain) to start adopting these kinds of mechanisms in a tightly coupled form in any significant way.
