Sample Bounty Ideas (playful / easy-but-not-trivial)

Highly summarized pitches, meant as raw input for the poster skill to turn into full bounty_challenge.md drafts — not full specs themselves.

1. Digits of Pi

Pitch: Compute the first 100 digits of Pi after the decimal point. Input: none (self-contained math task).

What is a Sun-Synchronous Orbit?

researched, extracted and summarized by Minimax-m3, Jul 1st 2026

The short version

A sun-synchronous orbit (SSO) is a near-polar low-Earth orbit (typically 600–800 km up, at an inclination of about 98°) that is carefully tuned so the satellite crosses any given point on Earth at the same local solar time every day — for example, always at about 10:30 in the morning. The orbit is "in sync" with the Sun, not with the Earth's rotation.

How it works (the clever trick)

PIPELINE.md — Hook Agent Operating Manual

This file is read by the isolated agent that wakes up on every LiteFold webhook callback (POST to hooks/agent) and every BIOS polling cycle. It defines all decision logic.

You are a pipeline controller, not a researcher. Your job is to evaluate results, advance gates, and notify Martin at decision points. Keep responses terse and factual.

Proof of Study Participation

We enable users to prove that they participated in a clinical trial / study without the conducting service or company (RH) being aware of the "crypto" aspect of their user identity. On the other hand, the prover (us) shouldn't learn anything about the actual user. Welshare's protocol also neither publicy correlates any user ids or personally idenitifiable information.

To enable this blindfolded proof issuance, we require minimal action on the service company's (RH) side. To initiate the proof creation process, they must be able to

identify one user by an unique identifier (UID) that can be unique for a trial instance
store a random array of bytes ("nonce") per user, ideally using a crypograpically sufficiently safe RNG. The nonce helps deidentifying the user
display the UID & the indidual nonce to the user / allow them to request it
invite study participants by their preferred means of communication to a decentralized web application, hosted by welshare

	If you need to auth against Nillion using an external wallet (and not a keypair), e.g. Privy / Metamask, you have several options. Good to know: Tim / Nillion Core already has merged EIP-712 support for account auth against NUCs / the Nillion nodes. This will solve a lot that I built customly.

	Here's the approach that I built at https://welshare.health to make something similar work, but we're additionally deriving purpose driven keypairs from Privy keys, using their signature over purpose-oriented EIP-712 payloads. Here's our docs: https://docs.welshare.app/basics/key-management. We're caching the private keys ephemerally on the user's client. This might change, as `did:nil` seems to be deprecated and replaced with the well understood did:key method soon (ask Nillion for reasoning, I'm just a "client" here ;) )

	If you feel adventurous, Privy actually can sign raw data, that would imo also work for other ecdsa / secp256 based chains (like Cosmos): https://docs.privy.io/wallets/using-wallets/other-chains
