The panic over lethal automated weapons systems is unfounded, and could be dangerous

Killer robots sound pretty scary. But we might be overlooking a few key aspects about their benefits, or at the very least, we’re looking at them the wrong way. To get more specific, I’m talking about lethal autonomous weapons systems (or LAWs), which are autonomous military robots that are designed to find and engage with specific targets based on their programming. дальше »

Researchers create ‘master key’ fingerprints that can fool biometric databases

Researchers from New York University have created a set of master fingerprint keys that can be used to spoof biometric identification systems. While the database of fingerprints used by the researchers had a chance of falsely matching with a random fingerprint one out of 1000 times, the master prints they generated had the power to falsely match one out of five times. дальше »

Crypto Experts Agree: It’s Not Wise to Compare Bitcoin (BTC) to Centralized Payment Systems

Bitcoin is the largest and most popular virtual currency in the cryptocurrency market. It can be used to process transactions of $1 million dollars or more or even $1 dollars’ transactions.

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 »
