On-chain lottery and scratch games are decentralized gaming applications built on a blockchain network. These games allow users to participate in a trustless and transparent environment, where the game results are determined by smart contracts and recorded on the blockchain. By using blockchain technology, on-chain lottery and scratch games eliminate the need for intermediaries and ensure that the games are provably fair. Players can trust that the games are not rigged or manipulated, and the payout system is automated, making it quick and secure. Moreover, the use of cryptocurrencies as the primary payment method enables players from all over the world to participate in the games without being limited by geographical boundaries or financial institutions.

Our team figure out that the primary goal of lotteries is to provide entertainment, it's worth noting that for many players, winning money is a significant part of the appeal. Lottery games that offer large cash prizes and the chance to change one's financial situation can be a powerful draw. That being said, it's important for lottery operators to ensure that their games are fair, transparent, and enjoyable for all players, and not solely focused on maximizing profits.
