These few lines of CSS code will crash your iPhone

A security researcher has found out that due to a vulnerability in WebKit (a rendering engine used by Safari browser), it takes only a few lines of CSS code to crash an iPhone or an iPad. The code itself is not too complex and uses multiple nested elements like <div> tags inside a CSS effect called backdrop-filter, used for color shifting behind the element. 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 »

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 »

Banks are attempting to launch Crypto assets with R3 Tech

Revealed exclusively to CoinDesk, Cordite, an open-source community that’s independent from R3, but building solely on the code it pioneered, is about to come out of stealth mode. Cordite promises to do for enterprise blockchains what the ERC-20 standard did for ethereum: allow the creation of different tokens representing various kinds of assets on the same network.
