Crypto’s fate might rely on Dai-based food truck experiments
- ETHDenver’s radical experiment to make use of Dai to purchase food had blended outcomes.
- Good information, 60% of transactions went via. Bad information, 40% did not.
- We spoke to Austin Griffith, who runs the undertaking, for his take on the way it went.
While a lot of the speak inside ETHDenver was on producing earnings by way of decentralized finance (DeFi), cryptocurrency’s most elementary use—as a method of fee—remains to be a piece in progress.
For the second 12 months in a row, all eyes had been on the interplay between the food vehicles and convention goers who had been armed with burner wallets loaded with “BuffaloDai,” the convention crypto.
How did it go? Eh, so, so.

Some purchases weren’t going via, or took for much longer to finish than bank card and money transactions. It was a reminder that establishing even a small fee system is a great deal of work.
But this wasn’t only a small fee system, not anymore.
“It’s probably more like an eight-month project jammed into six weeks,” Austin Griffith, director of analysis at Gitcoin, informed Decrypt. “You’re building the plane as you’re flying.”
He ought to know. The Colorado-based developer first rolled out Burner Wallet ultimately 12 months’s occasion so individuals may ship an event-specific cryptocurrency (on this case BuffiDai) between cell phone net browsers. Attendees used QR codes to load cash onto their burner pockets after which paid by scanning a QR code on their food truck of selection.
The thought was to create a pop-up financial system to onboard retailers and let individuals really use cryptocurrency. Everything labored easily a 12 months in the past, regardless of the curmudgeonly Decrypt correspondent’s few criticisms.
But this 12 months’s pockets and BuffaloDai was an “insanely ambitious project,” mentioned developer David Mihal. His curiosity was piqued by the experiment final 12 months, and he and two different part-time devs labored with Griffith to enhance the undertaking.
Security was tightened up by way of contract wallets. Last 12 months, person keys had been saved domestically. Though popup economies have restricted publicity, an attacker may have run up a invoice on the taco truck.
But that was only a begin. Other components allowed customers to do greater than merely purchase swag and sushi rolls. The pockets can now assist two tokens—BuffiDai for food purchases and XP for participating with sponsors. It would additionally function the gateway to a DAO that may decide the winner of the hackathon. Essentially, it will be the principle ingredient tying collectively 1,300+ attendees at work throughout 4 flooring.
Which is all effectively and good. But individuals nonetheless wish to purchase lunch.
Though loading the BuffiDai was painless for many individuals, sending that crypto to distributors was not all the time straightforward. One vendor sighed in reduction on the sight of a bank card. Another mentioned (at round noon Friday) that about 60% of transactions had gone via, however 40% had not. The truck had resorted to writing down wallet-based transactions by hand and, presumably, making an attempt to reconcile their numbers with the convention organizers afterward.
The BuffiDai group mentioned a bunch of small issues hit without delay. Griffith defined the distant process calls had been delayed by about 15 seconds, which means the system wasn’t processing quick sufficient.
Thankfully, as a result of this was a hackathon, there was an opportunity to enhance performance. “Basically, we just had to set up some better UX for the user. Everything technically worked, but if the user pulled [the send screen] up too early and [clicked send] to buy food too fast, then it failed for them…When we finally figured out it was just a timing [issue], we just put something in the wallet that said, ‘Make sure they’re connected before you hit send.’”
By Friday night time the whole lot was working as supposed. Moreover, attendees had a slick interface from which they might monitor how all of the nodes had been functioning, the place individuals had been spending their tokens, and even who was successful the race for XP tokens.
Still, there’s a threat that dropped transactions might dissuade distributors who’re making an attempt to regulate to a peer-to-peer system.
But that didn’t appear to be the case. “The DAI works great for us,” mentioned one vendor. “We had a couple glitches in the beginning, but they worked it out right away.” He added: “It is nice to have. Because of this event last year, we were able to accept Bitcoin throughout the year. We didn’t have that many people ask for it—but when they did, they loved it.”
