It's something that's been discussed. I've worked with @ekzyis a bit on potential models with the intention of applying it to prediction markets more broadly.
yes, i was very bad at time management the past weeks or months.
i hope this gets better now and i think i can get a first MVP of delphi.market out this month - fingers crossed.
(had to rewrite a lot of code since i realized, i can't just wing the frontend using raw HTML and CSS, lol.
I am using Vue 3 now.)

Awesome!
We'll keep cultivating demand amongst the degenerates in the meantime.

it's going to be binary markets only at first however
so literally just "Will X happen?" and you can buy YES or NO shares.
If you want to buy YES shares, someone else needs to buy the same number of NO shares. The price only differs. So if I think X is going to happen with a chance of 90%, I would buy YES shares for 90 sats each since I'll get 100 sats per share on expiry if I win. So a profit of 10 sats per share.
This means someone else needs to buy the same number of NO shares but for a price of 10 sats each. They'll win 90 sats per share.
A market evolves since you'll be able to sell your shares to others (at a different price you bought them). So you could sell X of your YES shares to someone else at 95 sats per share and exit the market with a profit of 5 sats per share before the market concludes.
If I did the math right, the market should stay solvent in any of such cases.
I also intend to use HODL invoices for these trades. So your sats for buying shares will only be sent if there is actually a counterparty available.
Also, I'll hold the funds. So it's going to be fully custodial. I'll ship on regtest first until I am super sure there are no bugs - at least no critical ones.

Looking forward to it
How do events get originated?
reply
Oh, great question, forgot to mention some things around that: You can simply create ones but I'm wondering if they should be approved by me first since if two parties can't agree on the outcome of the event, I'll have to step in as arbiter of truth. If the event is not easily verifiable, it's going to be hard.
I'm also thinking about requiring a bond which the party will lose that I decided has lost if the parties don't achieve consensus. So there is incentive to be honest since hopefully, I'll be able to tell who is the real winner easily anyway.

That oracle issue is tricky. It certainly doesn't seem like manually doing it would scale very well.
Essentially instituting a fee for disagreeing, gets you into a very interesting area of experimental economics. There are lots of circumstances where people are willing to pay their own money to make someone else lose theirs. As an irrational sports fan myself, I can imagine being willing to pay the fee to make sure someone didn't win a big reward (in certain circumstances).
That said, the bond approach is generally considered to be the incentive compatible approach.

Yes, but hopefully, I'll be able to find a better solution if this becomes a problem. A easy solution would be to limit market creation. So not many decisions required.

Yes, I can see that. But in this case here, only the loser would pay the fee. So you can't pay money to make someone else pay money afaict in this bond model 🤔
reply
Oops. Pardon my morning brain.
The bond is basically just the fee for making you look up the outcome. That's a great solution, because you can keep increasing it as volume increases, if you need to.
there, i said it. this month MVP @ekzyis' prediction market, lol
