So far you can bet on European football leagues, NBA, NHL, NFL, Copa Monero in Argentina and we just added prediction markets, so you can also bet on the next US president for example.

If you have suggestions for more prediction markets just let us know.

You are betting against other users not “against the house”

Thank you!

– “Doesn’t holding two keys in 3/4 multisig instead of one in 2/3 increases complexity?” Yes, however since we launched we changed the scheme from 3/4 to 2/3 multisig. This means that users can indeed have full control of funds and settle the bet in any way they agree. In Sigmanero you can’t contact the opposite counterpart, however, we you can always create a “private bet” that can only be accepted with whomever you wish. If Sigmanero disappears and leaves funds in multisig wallets, it is also possible for users to coordinate to get the funds back since both users will know the main address of the multisig, so they could in theory ask around, “who also has this main address?” and agree between them where to transfer the funds. Hope this makes sense and its not too much detail.

– “Would you consider sharing this work?” yes, especially the front end code which relies on the outstanding monerots library. There isn’t much more to add to it besides getting coordination sequence steps right. On the back end the code is unsurprising to be honest. Again just a matter of handling the steps of the multisig generation.
