Hello, yes, rubidity started as a joke (by Middlemarch a.k.a. Tom Lehman this summer). can it get any more stupid!? let’s try. some years ago i put together an ethereum simulator called universum (yes, in ruby). now that rubidity is a kind of better (or 100% solidity-compatible) version of secure ruby i put together a 2nd generation ethereum simulator (universum v2) called … drum roll, please … simulacrum. i published the first rubidity-simulacrum gem (v0.1) that lets you run (dumb) blockchain contracts in rubidity (with 100%-solidity compatible data types & abis) on an ethereum simulacrum in your own home for fun & profit (for free). happy blockchain programming with ruby & rubidity. ps: rubidity SOON! on mainnet.
