⛓️🧰 Substrate pallet to find a * b = N, given N and knowing that a and b are prime integers

Prime Product Pallet

Custom Substrate pallet which would help users to solve a particular problem.

The problem

With the equation

N = a * b

for a given uint N, find a and b, knowing both a and b are prime integers

Example:

Problem: N = 6

Solution: a = 2, b = 3

• Any user can submit new problem and set a non-zero reward for a solution.

• Any user can submit solution candidate for yet unsolved problem, and if correct, receive 80% of the problem's reward.

• The rest 20% of the reward stays in pallet's "treasury pool".

The following data should be stored on-chain:

• unsolved and solved problems,
• correct solutions.

Node Template

The source code of the pallet can be found here.

If you want to run the whole Substrate node, you can use the following command:

# to build the node
cargo build --release
# to run it
./target/release/node-template --dev

If you want to learn more about it, you can read the the node's README or the node's documentation.

How to use it

You can use the Substrate front-end template to get started with the node and the pallet.

First, in this case, Alice submits a new problem for N = 9 and offers a reward of 1_000_000_000.

Then Bob submits a solution candidate for N = 9 and, as it is correct, it gets the 80% of the reward of 800_000_000. You can check it in the events table.

The 20% of each reward stays in the treasury pool, 200_000_000.
