## Transcript

Transcribed by machine (Whisper) from the episode’s audio, so a word may be off here and there.

[1:20:00](https://realalpha.app/v/osuOwvEhVfQ/?t=4800) long direction so something we haven't talked about but i think i heard you speak uh i think this you said this in your stanford talk which i thought was interesting that there was multiple like near-death experiences or almost death experiences of robux we haven't talked about that at all there were several i think um one was the economy thing like if we had not figured that out that would have been very dicey looking back now i mean you were obsessed with science fiction there were all these other like virtual economies right at the time second life second life there.com Yeah. All of that stuff.

[1:20:31](https://realalpha.app/v/osuOwvEhVfQ/?t=4831) So were you taking ideas from that as well? There.com and Second Life, they really were early and in parallel to us. In a way, they were so early and so parallel, they made these very big visionary things. You know, Second Life's architecture was contiguous earth kind of thing, which had some issues around scaling because in a contiguous earth type situation, which is just the way the real world makes there's only one copy of that roller coaster and when 30 people want to go on that roller coaster no more can go so we i think we were a lot more practical around scale where it's like no man if there's if there's a hundred thousand copies of that roller coaster we're going to figure out how to route people to that so we could have 10 million people riding the roller coaster but there are a lot of early early visions out there i would say

[1:21:24](https://realalpha.app/v/osuOwvEhVfQ/?t=4884) at the same time for sure what was the argument from the the opposing board members to to doing the economy we had a lot of fun going on the platform like we're just like oh everyone's having fun building you know this viral stuff would we distort it if people could make money and but the idea the idea that look in the traditional game market you have studios with hundreds of people like we could probably get better quality if we nudged in that direction Other near death or rough things is our economy got hacked once. So we had to like shut down the whole economy for two days. Literally, that was somewhat scary. And the reason is we had just been so early moving so fast that the way our economy was working right now wasn't like double entry bookkeeping and journaling and all of that.

[1:22:17](https://realalpha.app/v/osuOwvEhVfQ/?t=4937) and we had no flow control anywhere in the economy. So this was a famous economy hack very early in the days of Roblox where the second the economy was hacked, money could bounce from place to place very quickly. We caught it pretty quickly and we just said, shut everything down. We had to shut Roblox down for a while then bring it back up without the economy on. Luckily, we caught it pretty quickly and only a small portion of the money had moved around.

[1:22:44](https://realalpha.app/v/osuOwvEhVfQ/?t=4964) But we had to run for several days with no economic activity. Were you already a public company when this was happening? No. No, no, no. The SEC does some really good stuff. And I would say some of the good stuff, if we go through a lot of the controls in the SEC, those were things we did 15 years ago, you know, as far as this economy and backups and all of that. When you were designing this, were there any, like, books you were reading or, like, were there any examples?

[1:23:12](https://realalpha.app/v/osuOwvEhVfQ/?t=4992) You're like, OK, I'm going to take an economy that I see functioning well in the real world and just make the virtual version. How did you even come up with the set of rules that you had? I would say all four of us founders were very into high integrity systems, like what's the amount of float in the economy? How much currency we have? Do you trade it and not trade it? We saw very early on in our economy, we had something really interesting in the early days of video games.

[1:23:37](https://realalpha.app/v/osuOwvEhVfQ/?t=5017) people would have multiple currencies and we had something that in retrospect the roblox community really loves but isn't really a good idea i don't think and that is a a participation-based currency called tickets as well as a money-backed currency called robux we the the thing that comes out is when you have a participant. It's a patient-based currency. You get one ticket for every day you log in.

[1:24:05](https://realalpha.app/v/osuOwvEhVfQ/?t=5045) That's really not a very good way to have people log into your system. You know, it's much better. They just love chatting with their friends or playing games. The other thing is any currency that a user can get from work or log in will immediately be bought it now. And so we could see people trying to bought that currency all day long, and we had to ultimately get rid of it um so we had some good learnings with that but ultimately our current economy it has you know as i've said is kind of scaled better than linear with user engagement you mentioned there's an advertising business inside of roblox that's right how long has that
