A prediction market is only as trustworthy as the odds feeding it, and most live odds feeds give you no way to check that a number wasn't quietly changed after the fact, which is the gap I built Matchday Ledger to close for the TxODDS World Cup hackathon on Solana. Every [Spoken audio]: If you've ever bet on a match, or just watched the odds move before kickoff, you already know the feeling, the odds shift and you have no real to know why or whether the number was even accurate a minute ago, you just blindly trust the platform. Today I want to show you something I built that removes that trust to permit entirely. It's called match day in ledger. This is a life prediction market born. This match is your scene here, Australia vs Brazil, New Zealand vs India, these are real live World Cup fixtures pulled straight from CX odds, CX line, feet in real time. Nothing here is placeholder detail, you can watch the odds take, the minutes count and the whole match play out. Now here is where it gets really interesting, remember that problem I just mentioned error, not knowing if an odd value was quite the change. Every single time this board updates, the app takes a snapshot of that moment and hashes it using the SHA256, then it changes the hash to the right one before it. So if you go back and try to change any pass value, even slightly, the entire chain from the point forward breaks. It's not me telling you to trust it, you can literally recompense this hash yourself right now your own browser and check if that you know actually matches out. And it's not just the math that's real. Behind the scene, the app performed an actual on-chain transaction on Solana. It's also called TXLine which unlocked the real API token. That token is what's authenticating every single fixture request you're seeing on this board. So the foundation and the need for all of this This trust chain isn't simulated either. I also added the wallet to connect KZ right here. Right now just displays your connected address but the first step towards something bigger in markets where you don't just want verified odds, we can actually stick on them and set to win these wallets to wallet with the same verifiable profitability running underneath. Now one thing I want to be upfront about, the odd movement and match simulation itself run client side. Using real fixtures data at the seed, we didn't get the light SSE on the stream fully wired in during this window partially because of two of CX line snapshot endpoints return errors during testing which are detailed in my API feedback for everything from on-chain transactions to live fixtures to the verification chain that part of that part is completely real To that match the ledger, taking the things we've always had to just trust about us and making it something that you can actually verify yourself. Thank you for watching, if you have any questions, please let me know in the comments below and I'll be checking everything out. Do feel free to check out match the ledger and let me know what you think about it. Thank you and have a nice day.
