      Further, many journalists writing about this paper have only interviewed its authors for commentary, neglecting to speak with industry experts. Please consider myself and the team @trailofbits a source when writing about blockchain security!

      In order to move this conversation forward, we’re calling on the MAIAN team to release the raw data they used to discover these issues, or share it privately with a qualified team capable of reviewing it.

      Oops! Lost in Twitter's threaded replies: "For example, they could have only counted contracts with at least X transactions or contracts that received more than Y ethers. Defining some kind of low watermark is essential for reviewing contracts on public chains."

      People often forget that the Ethereum main net was once cheap enough to be used as it's own testnet. https://twitter.com/dguido/status/966795503479480320 …

      Agreed. In the age of github, which is right now, one of the wonders of Academia is seeing data and code for reproducible results. Ten years ago college students had to forge around AFS for remote home directories for these things

      Yep it's sensationalist. The multi-trandactional approach is great though.

      We need to deploy something that detects & shows vulns in all mainnet contracts at scale. It's not that difficult.

      Replying to @muellerberndt

      I think that's a bandaid for the root cause problem that the tooling allows such insecure code in the first place. You shouldn't have to wait until deploy to find out something is broken.

      Replying to @dguido @muellerberndt

      IMHO A tool that "detects & shows" vulnerabilities at scale is far more useful to blackhats. How many defensive teams make adequate use of Shodan or respond to alerts from ShadowServer?

      Replying to @dguido @muellerberndt

      At the very least, the incidence rate of vulnerabilities detected is too high. Investing effort to lower the rate would make surveillance efforts more compelling.
