Online voting is insecure, period. This doesn’t stop organizations and governments from using it. (And for low-stakes elections, it’s probably fine.) Switzerland—not low stakes—uses online voting for national elections. Andrew Appel explains why it’s a bad idea: Last year, I published a 5-part series about Switzerland’s e-voting system. Like any internet voting system, it has … Read More “Security Vulnerability of Switzerland’s E-Voting System” »

I had no idea—until I read this incredibly jargon-filled article: Squid is a cross-chain liquidity and messaging router that swaps across multiple chains and their native DEXs via axlUSDC. So there. As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Read my … Read More “Friday Squid Blogging: Squid Is a Blockchain Thingy” »

Maintaining bitcoin and other cryptocurrencies causes about 0.3 percent of global CO2 emissions. That may not sound like a lot, but it’s more than the emissions of Switzerland, Croatia, and Norway combined. As many cryptocurrencies crash and the FTX bankruptcy moves into the litigation stage, regulators are likely to scrutinize the cryptocurrency world more than … Read More “Decarbonizing Cryptocurrencies through Taxation” »

Earlier this month, I and others wrote a letter to Congress, basically saying that cryptocurrencies are an complete and total disaster, and urging them to regulate the space. Nothing in that letter is out of the ordinary, and is in line with what I wrote about blockchain in 2019. In response, Matthew Green has written—not … Read More “On the Dangers of Cryptocurrencies and the Uselessness of Blockchain” »

Google took steps to shut down the Glupteba botnet, at least for now. (The botnet uses the bitcoin blockchain as a backup command-and-control mechanism, making it hard to get rid of it permanently.) So Google is also suing the botnet’s operators. It’s an interesting strategy. Let’s see if it’s successful. Powered by WPeMatico

Security researchers have recently discovered a botnet with a novel defense against takedowns. Normally, authorities can disable a botnet by taking over its command-and-control server. With nowhere to go for instructions, the botnet is rendered useless. But over the years, botnet designers have come up with ways to make this counterattack harder. Now the content-delivery … Read More “Illegal Content and the Blockchain” »

A malicious Chrome extension surreptitiously steals Ethereum keys and passwords: According to Denley, the extension is dangerous to users in two ways. First, any funds (ETH coins and ERC0-based tokens) managed directly inside the extension are at risk. Denley says that the extension sends the private keys of all wallets created or managed through its … Read More “Chrome Extension Stealing Cryptocurrency Keys and Passwords” »

At least one presidential candidate has a policy about quantum computing and encryption. It has two basic planks. One: fund quantum-resistant encryption standards. (Note: NIST is already doing this.) Two, fund quantum computing. (Unlike many far more pressing computer security problems, the market seems to be doing this on its own quite nicely.) Okay, so … Read More “Presidential Candidate Andrew Yang Has Quantum Encryption Policy” »
