      Are there are any proper papers, research or even just blog posts about shortcoming of Solidity's design from a security perspective? There seems to be a view the language is badly designed. Would like to change that perception by addressing issues.

      @AFDudley0, def. curious if you have an elaboration / write-up about your thoughts on Solidity.

      Thanks, I hope that by now all of my issues have been well documented elsewhere. Basically, the broken types of the EVM should be completely hidden from Solidity instead of inconsistently exposed. @MartinLundfall @fare are two people that come to mind who know better than I.

      There are many more outside the space like @maradydd @perrymetzger. @bramcohen's views on smart contract languages are spot on but don't don't expect him to provide a mapping. Samething with TxVM work. @mslipper has practical tips as well, I'm sure.

      I think stuff like alacrity, chialisp, and TxVM all compose together well. And if saying that I might as well mention EVM Evolution actually does a lot to address solidity issues, I don't know Brooke's twitter handle...

      Also, "just make Solidity a Haskell". Seems like a reasonable response.

      Are functional languages suitable for blockchain VM's? I love FP & RFP, but isn't there a performance trade-off? Thanks for any answers

      The short answer is, "yes".

      The slightly longer answer is: FP is designed to be the computational embodiment of formal logic, making it easiest to reason about programs. And reasoning about programs is EXACTLY what you need to ensure programs have the desired security properties and financial results.

          Well, imperative programs are not THAT hard to reason about, especially when they are small, like smart contracts are (or should be). Powerful typing system can catch a lot of simple errors early, but if you want full guarantee, the paradigm matters lesshttps://www.hillelwayne.com/post/theorem-prover-showdown/ …

          You can write C in Lisp and Lisp in C, it's a question of whether you're working with or fighting the language, and if you don't have sandboxing you can't have inner smart transactions in colored coins
