Show HN: Blockchain-based webapp allowing users to create arbitrary bets: WSBDD

Hi HN! These last couple weeks I've been working on what I believe is a really cool idea and think I'm finally ready to show you guys. WSBDD is a fully blockchain based web application, a single static page built using vanilla JS (you need MetaMask installed to interact with it). It allows you to place and schedule arbitrary bets over the contents of any website. It uses Provable's smart oracle[1] to query and extract results from the Internet, which then gets posted to the blockchain and used to determine the bet's winners and award their share of the loser's pool. If you feel like trying your luck, I've created a starting bet on the S&P's 500 price (decimals excluded) on October 9. You can place your bet up until next week's Friday (October 2nd) when the market closes. The website also includes links to the source code[2] and the verified smart contract's code[3].

I'd love to hear some feedback from you! I'm currently trying to think of the best way to handle the discoverability of bets. Right now I have a super simple section showing the last 10 created bets, but it's something I think could be considerably improved.

Also, I am not a big fan of the state of frontend development at the moment, so I decided that it would be a fun exercise to forgo any frameworks and see how far I can push things with plain old JS. I'm relatively happy with the results, but as you can probably tell I'm not a designer or anything of the sort, so any quick tips on that end are super appreciated. I'm now gonna start working on cleaning up the frontend, hoping this gets some discussion going!
