An academic project entitled Finding The Greedy, Prodigal, and Suicidal Contracts at Scale screened the vulnerabilities of Ethereum smart contracts at scale. They found a few--story below.
"Now, researchers say they’ve devised a new approach for finding vulnerabilities in smart contracts that would have exposed the flaw DevOps199 exploited before it was too late. Even more, the researchers say they’ve discovered an additional 34,200 vulnerable smart contracts. A sample of roughly 3,000 vulnerable contracts that the team verified could be exploited to steal roughly $6 million worth of ether, Ethereum’s in-house cryptocurrency, they said."
"We are gradually rolling out access to Robinhood customers residing in California, Massachusetts, Missouri, Montana, and New Hampshire, and look forward to releasing crypto trading functionality in many more states later."
"It remains to be seen how the Iranian project would, if realized, operate. If executed under the auspices of the Central Bank of Iran, the project would represent the latest effort to create a state-backed digital currency by an institution of that kind."
"Yesterday, the Securities and Exchange Commission voted unanimously to approve a statement and interpretive guidance to assist public companies in preparing disclosures about cybersecurity risks and incidents."
"In this article I attempt to summarize the numerous technical, social, and ethical problems surrounding the IOTA project, The IOTA Foundation, and the IOTA developers."
"However, a considerable distance must be traversed from declaring that government interventions are needed to deciding particulars for those interventions, much less intervening."
"These different goals—prediction and explanation—lead to very different modeling approaches. In many prediction tasks, causality plays no role. The emphasis is firmly on predictive accuracy. In other words, we do not care why a model makes good predictions; we just care that it does. As a result, models for prediction seldom need to be interpretable. "
"Investors and economists dutifully track the monthly economic data, but there’s something to be said for seeing how actual companies are experiencing changes in prices and wages. Consumer-goods and food-service businesses are great candidates, because they’re among the most sensitive and they happen to be in the midst of reporting earnings."
Bulletproofs are more efficient than STARKs (but BP is not quantum resistant), but certainly not more efficient than SNARKs (but BP needs no trusted setup).— Pieter Wuille (@pwuille) February 22, 2018
Since I’ve been talking about other people’s crypto mistakes let me talk about my own. Tim Ruffing found two flaws in Zerocoin (not Zcash!). One is a protocol flaw that allows you to burn money — but only if you can intercept transactions eg at a miner.— Matthew Green (@matthew_d_green) February 22, 2018
