Another game coin with centralized servers, and no authenticated proof over distributions.
When will this madness end?
1. This game is on Roblox servers. Future games may be on something else.
While this is certainly preferable to some servers you run yourself, it is still a "dangerous model" for coin distribution.
Let's look at some potential "attacks" that would be unique to this coin distribution, and that arise out of the trust in this central authority!
A) The Speed-hacker - An oldie but a goodie. Some older Roblox players (Personally, I happened to have played since alpha, hehe) know precisely where the server bounds the physics interpolation. Certainly some players will be playing at an advantage to others.
B) The Asset Ripper - I can assure you that your lua code and place files will be extracted from your server within minutes after publish. I hope the coin locations and/or keys are not easily retrieved from your place assets!
C) The Griefer - Roblox, being still in beta, has a lot of known instabilities. Someone could (trivially) knock your servers offline at key moments, or even keep them offline more or less perpetually.
D) The Glitcher - Roblox has many known "glitch" opportunities, particularly when either flight or vehicles are included in the mix. You should expect some people to be able to walk through walls, jump unusually high, and change one vehicle into another, giving them significant advantage.
E) The Bot Herder - Since servers allow for virtually unlimited "alts" someone could flood the hunt with bots to crawl the levels for coin, or to impede other players.
F) The Empl - Any employee or admin of Roblox has "god mode" and could choose to just auto-win the hunt. Keep in mind that Roblox has dozens of community volunteer admins.
2. The blockchain can help show proof of distributions.
Not really. It can show us that coins moved or not, but it cannot independently prove
any property of their distribution in this scenario.
