Summary of the Development with time report

In the past few months, we have encountered many difficulties in building the APP from scratch, but all of them have been solved. From UI building at the beginning to the development of smart contract later, to the recent integration wallet and contract extension, and finally deployed to the test network, enabling many users to experience the charm of Vegas . During this period, many users experienced it and modified some problems reported by users , Right now I think the first version of AEVegas is ready to be tested on the main web and have the SuperHero developers review the code and start promoting it


  1. AE main network update speed and JS-SDK speed update too fast
  2. There are not many oracle data providers for AE


1.As for the problem of updating too fast, you have to accept it, because updating fast means it is getting better and better
2.Since there are not many oracle providers for AE and AEVegas needs data to provide, it will not be able to run continuously if no one provides correct market results. We’ve come up with what seems like a good solution to this problem


We have added two types of market forecasts, personal and public
The answers to personal predictions are given by the creators
The answers to the public predictions are given by the community, and some people aggregate the data to calculate the highest vote-getters


Small oracles are built into the contract, the code is open-source, and the code is fully annotated

What can be improved?

I don’t think there is any need to improve it at present, it is kind of a game rule, later it may be better to increase the contract of oracle when predicting a fixed theme, such as predicting the price of BTC on a certain day, all this is automatically calculated, it will be better to add oracle at this time, of course, in the next version
