Due to Grant County’s lower power cost that comes from the local hydroelectric plant, many cryptocurrency mining operations have flocked to Washington state. However, their luck is bound to change as the Grant County Public Utility District (PUD) recently announced a rate hike for electricity used by cryptocurrency mining farms by as much as threefold, the International Business Times reported...The post %%POSTLINK%% appeared first on %%BLOGLINK%%. дальше »

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 »

Watch this immersive light show made with astronomical data

As a scientist, I was recently involved in bringing my work to the big screen. This was not a Hollywood sci-fi blockbuster but “big screen” in the literal sense: an art production about science that used the Lovell radio telescope, a 3,200-ton steel behemoth supporting of a 76-meter wide dish, to generate and show audio-visual art that drew on scientific data. дальше »

When Smart Contracts Act Stupid: Is Your ICO Smart Contract Safe & Secure?

The potential inherent in smart contracts is immense. The nascent technology may be used for identity verification, secure data sharing, and for the management of tokens and raised funds in an initial coin offering/token sale – but just how clever are your smart contracts? The Ethereum network boasts more than 1500 decentralized applications (dApps), all of which make use of smart contracts to accomplish a wide variety of tasks. 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 »

STARKs, Part I: Proofs with Polynomials

Special thanks to Eli Ben-Sasson for ongoing help, explanations and review, coming up with some of the examples used in this post, and most crucially of all inventing a lot of this stuff; thanks to Hsiao-wei Wang for reviewing Hopefully many people by now have heard of ZK-SNARKs, the general-purpose succinct zero knowledge proof technology that can be used for all sorts of usecases ranging from verifiable computation to privacy-preserving cryptocurrency. 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 »

Op Ed: Addressing the Threat of Cryptomining Malware

One major class of attacks to hit the hacking landscape recently is cryptomining. While cryptomining on its own supports a good cause when being done consciously, it also allows nefarious actors to make a lot of money fast, and, with the sheer number of cryptocurrencies available to mine, it is becoming a popular choice for attackers. дальше »

PoWx Seeks to Change Bitcoin Mining with “Optical PoW”

Nonprofit organization PoWx has launched this week with the goal of boosting the idea behind proof of work (PoW) through more innovative algorithms. The company is seeking to decentralize Bitcoin mining and make it more accessible to consumers through a new technology that executives have dubbed “optical PoW” — a new type of hardware that utilizes a more advanced and energy-efficient form of laser technology as the cornerstone of mining. дальше »
