Feel free to suggest features or topics that you would like to bet on.

We're thinking of using ecash tokens to enable buying and selling of shares in events. Right now we have a set up where the "winners split the losers sats" (parimutuel betting market), but there are other more sophisticated market making mechanisms that enable more accurate forecasting (LMSR).

With ecash we could enable those mechanisms while preserving privacy. Basically we could create polymarket-level functionality without even requiring users to sign up—the ecash tokens would be downloaded, emailed, or sent to an ecash wallet, and selling or redeeming the shares could be facilitated by uploading the tokens.

If we represent shares as ecash tokens then the ecash basically operates as the authentication mechanism for ownership of shares. When you sell or redeem your shares, you could simply provide a lightning address. No need for identity tracking either, so you could place bets anonymously (as long as you can always generate a new lightning address).

Let me know if that sounds cool to y'all.

Ecash DLCs would be pretty cool, see #544786

121 sats \ 0 replies \ @HYPERBITCOINZATION OP 14 Oct

Yeah so it looks like ecash DLCs run into similar problems with standard DLCs in designing a prediction market with an LMSR market maker.

We did some research into creating an LMSR prediction market with DLCs earlier this year. The main problem with it is you need to code up a transfer mechanism for DLCs, and there are much higher liquidity requirements compared to ecash.

We really did want to go for a non-custodial technology as the base, but it would just massively increase the cost of development and time to market. Ecash can enable a pretty good UX of a prediction market natively with Bitcoin, comparable or even better than polymarket. No authentication needed, as the ecash token is the authentication mechanism for you to redeem the value of your shares. DLCs may make the prediction market UX worse than other platforms, and I feel like the trade off wouldn't be very profitable.

how does Bitcoinprediction fund itself?

IE what percentage of the betting pool does it take from the winner?

In general I see gambling as a losers game (when there is a centralised house taking in a guaranteed cut) but for a prediction market there is a case for it.

If it can serve to give a representation of what people believe will happen it could be of value- certainly more value than standard gambling operations.

Currently we are funded by Wolf and Entrepreneur First (two startup accelerators) and we're charging a 1% tx fee.

Yeah initially I thought prediction markets were just degen gambling, but now I realize that they are market-based forecasting tools that enable people to get a sense of what will happen in the future.

As a financial technology, Bitcoin is a prefect monetary mechanism to facilitate prediction markets due to its decentralized and censorship resistant nature. As a social technology, prediction markets offer a novel use-case for both Bitcoin and ecash, enabling people to use their Bitcoin for more than just hodl.

31 sats \ 0 replies \ @Solomonsatoshi 14 Oct

Thanks for your reply and 1% fee seems reasonable. We used to have a prediction website here in New Zealand and it was run by academics from one of the universities (using fiat) it was called 'ipredict' and it was very popular - unfortunately a supposedly right wing free markets government here closed it down- they did not like the idea of citizens having the ability to back their predictions with their own money. Alot of the political polling in New Zealand is partisan operated and they want to control it. So yes a Bitcoin based model is excellent and should be more resistant to meddling politicians who just want to control the narrative and not allow us to know what others are thinking and feeling about the issues of the day. Good on you for starting this up its a fun and informative way we can use Bitcoin. Given the academic research and perhaps market research potential of such a platform there may be interest from researchers and the like. All the best.

Cool, what guarantees are there that the owner of bitcoinprediction.info doesn't simply run away with the money? and doesn't pay winners?

10 sats \ 2 replies \ @HYPERBITCOINZATION OP 14 Oct

Well our main objective is to run a profitable business. If we steal people's money, then we lose trust, and therefore lose customers. We are incentivized to provide an honest service, else we will not grow. The long-term vision is a private and anonymous polymarket but with sats and ecash, not FTX.

We also looked into how to do non-custodial prediction markets with DLCs, and we have a draft of a whitepaper detailing how to do LMSR over DLCs. The only issue is currently we need a transfer mechanism (or swap) for those DLCs, which doesn't yet exist in the spec. We could try to raise more money to hire people to do that, or we could just go with ecash (which already has a thriving community of developers).

The difficulty with DLCs also is that everything needs to be on-chain. Lightning based DLCs are a mega pain in the ass, we talked to 10101 guys about it. If everything is on-chain then anytime there are high fees, it would be more costly for people to place bets. Lightning solves this, but Lightning also precludes other technologies due to the complexity of operating a Lightning based service in the first place.

We want to guarantee payout reliability, as even typos in the lightning address can result in payment failure. That's why we want to abstract shares as ecash tokens, and enable people to save their shares as a file (or emailed to them), which can be uploaded later.

Just a suggestion for further research, this is another newer option that allows for the dlc contract to enforced on chain in an efficient manner but allows for buy-ins and pay-outs over lightning when everyone cooperates: https://github.com/conduition/dlctix

It'd be nice to have Matt Levine pieces posted here to SN. I like his style, but only read him occasionally as I just forget to visit his column.

1 sat \ 0 replies \ @denlillaapan 6 Nov

same! I read him pretty religiously.

He had a good take about the differences across prediction platforms

I wrote yesterday about an apparent arbitrage in US presidential election prediction markets: Donald Trump contracts on Polymarket trade at about a 53% chance of him winning the election, while they trade on other prediction markets at more like a 49% chance.[2] If you can buy Trump at 49 elsewhere and sell him at 53 on Polymarket, you can make a quick 4-point profit. I did not take this too seriously, and you shouldn’t either. I assumed that it probably wasn’t a feasible arbitrage: “I am sure there are some fees that I am not accounting for,” I wrote, “and I don’t know how good liquidity is on any of these places.” Also Polymarket is in theory off-limits to US investors. Those sorts of things — trading costs, liquidity, capital constraints, etc. — are the normal explanations for differences in prices in different locations, “limits to arbitrage” that prevent people from selling the expensive contract on Polymarket and buying the cheap one on Kalshi or wherever. But the other natural reaction you might have to seeing the same contract trade at different prices in different locations would be: Well,** are they the same contract?** What if “Donald Trump will win the election” is worth more — that is, has a higher probability — on Polymarket than it does elsewhere? That seems implausible: There is only one presidential election, and Trump will either win it or he won’t. But that might not be exactly right. There is some history of epistemic uncertainty when Donald Trump loses elections. Different prediction markets might resolve that uncertainty in different ways.

I have been looking for an alternative to the centralized BetMoose

Who decides the outcomes of the bets and how?

75 sats \ 3 replies \ @HYPERBITCOINZATION OP 14 Oct

We currently decide the outcomes of the bets. so the oracle is the Bitcoin Prediction Market team. We're looking to decentralize this by using ecash mints to enable anyone to run their own prediction market, ask questions, and provide liquidity.

The issue with a fully decentralized p2p prediction market is then you can't use something like LMSR (or at least I currently don't know how you'd architect that kind of solution). The point of the prediction market is to centralize liquidity around a market maker, which can use those bets to forecast the future. If all the bets are p2p, then you can't gather that intelligence, which is a major drawback.

We sure do :) The more the merrier. However, our prices and shares are more competitive and more predictable. LMSR > Parimutuel.

21 sats \ 3 replies \ @HYPERBITCOINZATION OP 15 Oct

LMSR is indeed a better forecasting tool than parimutuel auctions, but some foresight is required to have a good calibration of the b constant to match the expected liquidity.

121 sats \ 2 replies \ @mega_dreamer 17 Oct

Agreed, managing b is the most difficult task. We are learning the hard way after seeing so much liquidity being wasted in thinly traded markets(over liquidated). We came to a conclusion that having a foresight is very difficult for novel markets, and its easier to build a reactive liquidity management system based on market volume and frequency to maintain a good enough calibration.

BTW we've also dabbled with parimutuel and it still exists on our sports betting app(triible). But, for some reason people seem to be more gravitated towards fixed odds on Triible, not sure why, but my reasoning is that maybe people prefer predictable outcome as opposed to a chance of a windfall gain which is only possible in parimutuel. But again, that's my observation on Sports Betting. Prediction Markets are different beast altogether and the same may not hold true.

Looking forward to connecting with one of these days :)

171 sats \ 1 reply \ @HYPERBITCOINZATION OP 17 Oct

This article gave me some inspiration with regards to LMSR and the cost of running the market.

Triible looks cool, censorship resistant betting could be a massive driver of Bitcoin adoption globally. I first bought Bitcoin in 2017 to gamble it away on Pokerstars (Fiat to Coinbase to Bitcoin to Zelle to Pokerstars). Seems like the product-market fit was already there, it's just about the UX and building out a network effect. I even played csgo poker, where I could deposit my csgo skins and gamble at super micro stakes (like 0.1c/0.2c). Bitcoin Lightning could be a perfect medium of exchange to enable that, but it's less about building product and more about getting it to market, and getting traction from paying customers.

Most definitely would love to chat, I'll be at Tabconf and Adopting Bitcoin later this year. You planning on going to any conferences?

Yeah we didn't expect this many people to actually place a bet, and we also didn't expect all the errors to pop up with sending payouts. Liquidity issues, limits on receiving, pending HTLCs, routes not available, etc. Lightning still has a long way to go because we simply can't repay people if reliability is not guaranteed. When we get the error "invalid lightning address" then it's kind of tough to send a payout to that person.

If you have a pending payout let me know and we can sort it out manually.

I bet at 60-40 and paid with 80-20 odds. Doesn't make any sense. I wouldn't have bet at those odds because the amount/reward was not worth it

So our node is online, channels have sufficient inbound/outbound liquidity, and other wallets work. Many times lightning payments fail because of pathfinding issues between the nodes.

Your node might be struggling to find a route because of the decentralization of the Lightning network. As the network becomes more decentralized, payments become harder to process simply because the native pathfinding algorithm sucks.

I can look into opening some direct channels with coinos.io wallet, maybe that can help.

We're running a parimutuel market setup at the moment (winners split the losers money in proportion to how much they bet), but we want to move towards a modified version of LMSR. LMSR is a better forecasting tool, as long as you set the liquidity parameters correctly.

When a user bets we basically calculate how much their proportion of the winnings are if they won without any changes to the liquidity. So like

odds = (sats bet yes)/(sats bet yes + sats bet no) potential return = (your sats bet yes)/(total sats bet on yes) * (total sats bet on yes + no) or (your sats bet no)/(total sats bet on no) * (total sats bet on yes + no)

It's not the best system, LMSR is better, but it's good enough for a short-term auction (akin to horse racing).

The reason we want to transition to an ecash system rather than just custodial lightning is because that would enable people to sell their shares before market close (currently we cannot facilitate that with just Lightning payment & address). Then people could bet -> receive ecash tokens (representing shares) -> download or save those ecash tokens. Then whenever they want to sell or redeem the value of their shares, they can upload those tokens and enter in a receive address (lightning or on-chain), and then the market maker could send sats to them.

Another reason we're going for ecash is because it is effectively an authentication mechanism for people without needing to give an email or npub or signing up at all. We'd much rather avoid the UX of signing up to place a bet, and rather enable anyone to be anonymously, as long as they have access to a receive address in the future. Then we could list the bets with just bet amount and position, and we don't even need to reveal the lightning addresses while keeping everything publicly auditable.

Do you not deduct any fees?

It's just weird that odds for Trump and Kamala add up to 108%. But it does not mean that betting on all outcomes will make a profit for this guy:

Did you remove the link to the stats?

Stats are listed below the topics. Click on the title of the topic to go there. We thought it would be better to show all the stats below the topics, rather than on a separate page.

We show the bets placed, but the fees are deducted when we send the payouts (1% fee at the moment). The total odds add up to 108% because it is basically

Odds_total = Odds_Trump + Odds_Kamala = Y_T/(Y_T+N_T) + Y_K/(Y_K + N_K).

Both markets are independent (betting on Trump does not change Kamala's odds, it only changes Trump's odds), so they are not necessarily supposed to add up to 100%. For a clever user like yourself there's an arbitrage opportunity there to balance the odds. Few people have spotted that so far.

from ChatGPT:

How Arbitrage Works: For arbitrage to exist in a betting market, the combined implied probabilities of all outcomes must be less than 100%, allowing you to bet on both outcomes and lock in a profit regardless of who wins.

For example, if Trump were at 60% and Kamala were at 35%, you would have a combined 95% probability (less than 100%), and you could profit by betting on both sides. However, in your case, the total is over 100%, so no arbitrage is present.

Congrats on the launch!!! Would love to chat how you're using ecash.

21 sats \ 3 replies \ @HYPERBITCOINZATION OP 15 Oct

Thanks, yeah would love to chat. Basic idea we're going for is to use ecash tokens as IOU receipts representing shares in the event, thereby enabling buying & selling of shares via variants of LMSR.

0 sats \ 2 replies \ @mega_dreamer 17 Oct

BTW I run Predyx, that make us competitor :)

Jokes apart, yes, I've gone through the same pain as you've gone through. Tried to implement LMSR with DLCs but failed. I love the idea of ecash being a bearer token, it solves a lot of usability problems. Can we jump on quick 30 min call next week? Would love to get to know you and learn about ecash.

I've also been tinkering with Taproot Assets to issue market shares and backing up the shares with equivalent amt of sats on PSBTs, but again that locks up the liquidity and on-chain tx may not be financially viable for micro bets.

Any good idea should have some competition, and right now polymarket is the big one to compete with. Similar to crypto exchanges, there's room for 10-20 multi-billion dollar prediction markets by 2030.

I have a better suggestion: use the new and powerful Liquid scripting to turn your market into a smart contract. So that everything is transparent and trustless (well, almost: you trust the Liquid Federation)! Ecash requires trust in anonymous entities, which is a no go for me.

0 sats \ 8 replies \ @HYPERBITCOINZATION OP 14 Oct

I'll take a look into it. I talked to Adam Back in Tokyo and he told me about the limit order book and token functionality on Liquid. I think it would be a solid foundation, but I'm not sure if there is an order of magnitude improvement in terms of UX over Lightning payments to make bets or send rewards and ecash tokens as shares.

In essence, the trader is always trading with a market maker, not p2p. The market maker must use LMSR (or some variant) to determine accurate forecasting of the event via the share price. So regardless, you'd still be trading with the LMSR market maker, regardless if it is on the Liquid sidechain or the ecash mint (which means you'd still be trading with us). You'd still need to trust the smart contract, that it operates properly, as designed. Even open source smart contracts can have bugs that hackers can exploit. Regardless of what product you have, there are still vulnerabilities to audit and be aware of.

The reason we use ecash, rather than authenticating with a lightning wallet, or on-chain Bitcoin addresses, is because ecash enables you to download and save your shares anonymously, and it's pretty quick to build compared to DLCs or Liquid. Investing in the R&D effort before we raise extra funds or have significant traction seems like a waste of time, though it might be good later down the line to invest in that kind of infra.

This is about transparency, not efficiency. Your site is a black box that can rug pull us any moment. Boltz is a market maker, but is trustless if you host the frontend yourself or use our SwapMarket. Smart contracts can create DEXes, but Ethereum sucks. The Bitcoin alternative to create smart contracts is currently Rootstock or Stacks. Liquid Federation solution promises to be more robust and trustworthy blockchain.

0 sats \ 6 replies \ @HYPERBITCOINZATION OP 15 Oct

Yeah and if we use Liquid smart contracts then SwapMarket could benefit. I understand more projects using alternative platforms means more potential revenue for y'all, but we need to prioritize the ability to get product to market in a reasonable amount of time. Once it's easier for us to build (either lower technical requirements, or we have more capital and time) then it would make sense for us to do that.

We care about building features that the vast majority of users really care about, not trying to win the virtue signal Bitcoiner purity test.

Oh, I did not even think about that. SwapMarket is a non-profit hobby project to benefit Bitcoin. Swap providers compete for client flows.

At least, publish your source code. Your node is small and young, pay-outs are not transparent. Too many red flags.

All transactions are public and fully auditable. Payouts are fully transparent: the winners split the losers sats. You can do the calculations yourself, or you could be lazy and push FUD by being a hater. If you don't want to use it, then don't use it, we're not forcing you.

I did place my bets, to test it out. My goal is to make your site better, not to spread FUD. By the way, there is a typo in "Total Bets: 3284581 stats".

I don't like that you show everyone's bets with full lightning addresses. Better mask them for privacy with something like this: y...7 @walletofsatoshi.com

There were no payouts yet, so blaming me to be lazy is unfair. I will do the calculations after the elections, don't worry.

However, I already noticed a problem with Who will win the US election? stats. I cannot find my bet placed yesterday:

Ok fair enough, I can see you're very knowledgable and providing constructive feedback. I apologize for the bug there. It seems as if your payment coincided right when my co-founder was deploying an updated backend. The pending payment was recorded, but it seems like the payment confirmation was not. The table we show is only displaying confirmed payments, and since there was a backend deployment interrupting that process, once the pending payment got confirmed it didn't get successfully recorded. We've now listed your bets on the status page, hopefully we won't run into the same error again.

We're working on fixing that bug so any future backend deployments won't run into the same issue. Thank you for bringing that up.

Our objective has been to figure out how to create a long-term prediction market on Bitcoin with the best security and UX. Of course custodial isn't the ideal or optimal way, but it would be foolish of us to spend months developing product when we're uncertain of the actual market demand (been there, done that, it's not worth it).

I was doing some research into how to do non-custodial prediction markets with DLCs. I can see that it is possible, it just requires much more capital, time, and energy to build. Same goes for building on Liquid—we are in a crunch time period and need to fundraise soon, so we just don't have the time or resources at the moment to commit to building a super sophisticated product, just an MVP. In an ideal world we could raise a shitload of money from VCs and hire some wizard cypherpunk devs, but alas we are only a team of two figuring it out as we go along.

I really do appreciate your feedback.
