Lottery on-chain it's not new anymore.
We already seen this, so it's really a not new topic. Most of lottery are using "RNG" system, If you looking on-chain lottery you can take a look from "PancakeSwap". This decentralized exchange provided a lottery for their community.
It's already been implemented on the chain.
I don't think that any of them are using semi-fungible tokens (ERC-3525 protocol). But personally i don't understand the benefits of it or how this would work yet (compared to RNG)
Maybe op can shade some light and explain how ERC-3525 can be used for gambling and how that's superior to normal smart contracts we already have.
Please refer to the link below about the ERC 3525 part.
https://xwinnergame.gitbook.io/x-winner/technology/erc-3525-sftThis mechanism used by X WINNER is designed to provide a fair and equitable distribution of shares to all players. By purchasing lottery tickets, players can not only participate in the game and potentially win prizes but also become shareholders in the game. The allocation of shares based on ticket price ensures that all players have an equal chance to become a shareholder, regardless of their financial resources. Moreover, the fixed percentage of Stable Tokens injected into the revenue pool ensures that the game has a stable and sustainable source of revenue to support its operations and future developments. By introducing multiple rounds of LOTS and gradually reducing the number of shares available over time, X WINNER incentivizes early adoption and rewards those who believe in the project's long-term vision.
However, our team also employed ChainLink VRF for RNG, and uses an algorithm for the fairness of the game results. Please refer to the link below:
