    Project Overview (Verifiable Random Function) will generate pseudorandom numbers in a deterministic fashion. That is to say, simply generating a random number is not good enough. We need to be able to prove it is random and this goal will be achieved using Verifiable Random Function. We need to create a module that can generate a deterministic random function. This random number should be able to be verified by other participants. Each node takes a seed and private key to generate a pseudo random number and a proof pi. Fx(seed number) = random number, proof pi Fx (last hash) = 1421123151, 131235231 Using the random number, the node will shuffle the participating list of nodes and divide them into 3 buckets. Original list [ node 1, node 2, node 3, node 4, node 5, node 6] Fx(seed, origin...

    Project Overview: -Our system is going to be composed from a variety of underlying base modules that will be used to define all of the abstractions for actors, their actions, and their relationships. With the premise to remove as much trust from the system as possible it requires a heavy reliance on cryptographic protocols. You will be tasked with adding a Distributed Key Generation pkg to the key generation module. We need a standardized struct to encapsulate a generic interface shared by our current & possible future implementations for Distributed Key Generator (DKG) to allow for a consolidated method that changes dynamically depending on the context. An example of distributed key generation implementations that we need are: FROST Schnorr DKG using ED25519 Feldmann Secret Sharing...

    I have some daily tasks that i have to do for work which are very boring and time consuming. the tasks are to place thousands of orders for services on a website. I wanted to automate this and i'm a software developer myself so i started using macros then switched to selenium. i tried so many things including blocking images for the site but still all of that is not fast enough because the site itself is slow too. So i thought i should communicate with api directly without having to use a browser at all. but now i have some problems. the api is strange unlike the apis i work with. for example to create an invoice, the browser posts this data to a url fjOd3pbxQN5L and it's static so i know posting this data will always create me the same invoice which i need. Server responds with ...
