Is ML powerful to predict lottery numbers on pancakeswap?

Steve Gerrad — Wed, 13 Jul 2022 07:55:21 +0000

Can I see the strength of ML, is it possible to predict pancakeswap lottery numbers using ML?

As a full stack blockchain developer, I have more than 5 years experience. So it's a piece of cake to fetch the lottery data.
Here is the script I used for the fetching the history of pancakeswap lottery.

const ethers = require('ethers')
const reader = require('xlsx')
const abi = require('./abi.json') // Lottery
const mcAbi = require('./multicall.json')
const file = reader.readFile('./lottery.xlsx')

const address = "0x5aF6D33DE2ccEC94efb1bDF8f92Bd58085432d2c"
const mcAddress = "0xfF6FD90A470Aaa0c1B8A54681746b07AcdFedc9B"
const rpc = "https://bsc-dataseed.binance.org"
const provider = new ethers.providers.JsonRpcProvider(rpc)

const mcContract = new ethers.Contract(
    mcAddress,
    mcAbi,
    provider
)

const fetch = async () => {
    const itf = new ethers.utils.Interface(abi);
    const calldata = [];

    for (let index = 1; index < 593; index++) {
        calldata.push({
            target: address.toLowerCase(),
            callData: itf.encodeFunctionData('viewLottery', [index])
        })
    }

    const { returnData } = await mcContract.aggregate(calldata)

    const res = returnData.map((call, i) => {
        const result = itf.decodeFunctionResult('viewLottery', call)
        const finalNumber = result[0].finalNumber.toString();
        const date = new Date(Number(result[0].endTime.toString()) * 1000)

        return {
            timestamp: result[0].endTime.toString(),
            year: date.getFullYear(),
            month: date.getMonth() + 1,
            day: date.getDate(),
            hour: date.getHours(),
            minute: date.getMinutes(),
            second: date.getSeconds(),
            'number 1': finalNumber[6],
            'number 2': finalNumber[5],
            'number 3': finalNumber[4],
            'number 4': finalNumber[3],
            'number 5': finalNumber[2],
            'number 6': finalNumber[1]
        }
    })

    const ws = reader.utils.json_to_sheet(res);
    reader.utils.book_append_sheet(file, ws, "Sheet2")
    reader.writeFile(file, './lottery.xlsx')
}

fetch();

I was wondered that pancakeswap start the lottery every 12 ~ 36 hours and every prize pots are more than 70k.
It means there are chances to earn 25k in every 2 days.
Oh, what a surprise!!!

I want to know the possibility of predict lottery numbers using ML.

Note that pancakeswap lottery uses Chainlink's implementation of VRF for secure randomness.
