Body

Now I am developing Perpetual contract trading back-end.
I have one question in this.
Platform have over 10000+ users.
In this case how can back-end occure transaction of all users at once?
As you know, blockchain traction require a little exeuction time on chain trading.
if so, the last user's transaction will be occure after delay.
I wanna know how to solve this.

Thanks

hello,
This is very good question in trading back-end development.
MT5, MT4 and Crypto trading is similar to each other.
I think you will develop back-end with Node.js
There is promise function in node.js
This function enable to compose and chain multi async function.

please look at this:

// Function to simulate a task with some execution time
function simulateTask(id, time) {
return new Promise((resolve, reject) => {
setTimeout(() => {
console.log(Task ${id} completed in ${time}ms);
resolve(Task ${id} result);
}, time);
});
}

// Simulate tasks for each circle from 0 to 1000
const tasks = [];
for (let i = 0; i <= 50; i++) {
const taskTime = Math.floor(Math.random() * 100) + 1;
tasks.push(simulateTask(i, taskTime));
}

console.log(tasks);

Promise.all(tasks)
.then((results) => {
console.log('All tasks completed:', results);
})
.catch((error) => {
console.error('Error:', error);
});

if you run this, code, several task is finished at once.

This is main thing in trading back-end.

Thank you
