I am glad to see websites popping up with blockchain gambling services. But blockchain lottery is nothing new, really. A lot of such projects like to make claims like "trustless and transparent" however they fail to provide an open source as well as a a smart contract audit and a non-custodial wallet experience. So unless your lottery system has been tried and proven by the community, I would not be ready to accept such grandiose claims. Decentralized does not automatically make it "provably fair".
Players can trust that the games are not rigged or manipulated
I think word trust should not be used together with "provably fair". A Certik security audit is not the same as an audit in functionality and fairness. So which audits other than security audits can you offer?
You are absolutely correct my friend, this is exactly the same direction I was going to in my previous comment, like you said, this is not the first decentralized lottery game being announced on this forum, there have been many of them, but at the current states of things, centralized casinos that have built a good reputation over time are trusted more than any decentralized casino at the moment, this is why non of the previously announced decentralized casino have succeeded so far.
For me personally, before I can try any decentralized casino or lottery system, the owners must make the code of the entire system open source, and must present a full smart contract audit from a reputable and reliable audit company, any thing less, I will prefer to keep playing on centralized casino I trust.
