A Guide to 99% Fault Tolerant Consensus

Special thanks to Emin Gun Sirer for review We’ve heard for a long time that it’s possible to achieve consensus with 50% fault tolerance in a synchronous network where messages broadcasted by any honest node are guaranteed to be received by all other honest nodes within some known time period (if an attacker has more than 50%, they can perform a “51% attack”, and there’s an analogue of this for any algorithm of this type). дальше »

Governance, Part 2: Plutocracy Is Still Bad

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. дальше »

Notes on Blockchain Governance

In which I argue that “tightly coupled” on-chain voting is overrated, the status quo of “informal governance” as practiced by Bitcoin, Bitcoin Cash, Ethereum, Zcash and similar systems is much less bad than commonly thought, that people who think that the purpose of blockchains is to completely expunge soft mushy human intuitions and feelings in favor of completely algorithmic governance (emphasis on “completely”) are absolutely crazy, and loosely coupled voting as done by Carbonvotes and similar systems is underrated, as well as describe what framework should be used when thinking about blockchain governance in the first place. дальше »
