Implementing Giveaways in Blockchain

0 votes
I'm building a project that does a giveaway everytime the counter reaches 100k.

There are many people that can get the giveaways. It is not that only one person out of all gets the giveaway.

Every person has a Unique ID and I am randomly giving different types of gifts to them.
I dont understand how to implement this.

I have found a similar question. The solution mentioned there was:

int(hashlib.sha256(block_header + userID).hexdigest(), 16) / float(2**256)

You conver the hash into an integer, then divide that integer by 2**256. This gives you a decimal from 0 to 1 that can be compared to a random.random() to get the prize.
