We wanted to make the simulation interactive, shooting planets, manipulating gravity, to make a fun game! This simulation also allows testing to see what initial conditions allowed the formation of our solar system, and potentially in the future, macroscopic astronomical entities like galaxies!
## Inspiration

The inspiration for this project came from my passion for decentralized technology.

One particular niche of decentralization
I am particularly fond of is NFT's and how they
can become a great income stream for artists.
With the theme of the hackathon being
exploration and showing a picture of a rocket
ship, it is no surprise that the idea of space
came to mind. Looking into space photography, I
found the [r/astrophotography](https://www.reddit.com/r/astrophotography/)
subreddit that has a community of 2.6 million members.
There, beautiful shots of space can be found,
but they also require expensive equipment and
precise editing. My idea for Astronofty is to
turn these photographs into NFT's for the users
to be able to sell as unique tokens on the
platform while using Estuary as decentralized
storage platform for the photos.

## What It Does

You can mint/create NFT's of your
astrophotography to sell to other users.

## How I Built It

* Frontend: React
* Transaction Pipeline: Solidity/MetaMask
* Photo Storage: Estuary

## Challenges I Ran Into

I wanted to be able to upload as many images as you want to a single NFT so figuring that out logistically, structurally and synchronously in React was a challenge.

## Accomplishments That We're Proud Of

Deploying a fully functional all-in-one NFT marketplace.

## What I Learned

I learned about using Solidity mappings and
structs to store data on the blockchain and all
the frontend/contract integrations needed to
make an NFT marketplace work.

## What's Next for Astronofty

A mechanism to keep track of highly sought after photographers.
## Inspiration

Witnessing the atrocities(protests, vandalism, etc.) caused by the recent presidential election, we want to make the general public (especially for the minorities and the oppressed) be more safe.

## What it does

It provides the users with live news update happening near them, alerts them if they travel near vicinity of danger, and provide them an emergency tool to contact their loved ones if they get into a dangerous situation.

## How we built it

* We crawl the latest happenings/events using Bing News API and summarize them using Smmry API.
* Thanks to Alteryx's API, we also managed to crawl tweets which will inform the users regarding the latest news surrounding them with good accuracy.
* All of these data are then projected to Google Map which will inform user about any happening near them in easy-to-understand summarized format.
* Using Pittney Bowes' API (GeoCode function), we alert the closest contacts of the user with the address name where the user is located.

## Challenges we ran into

Determining the credibility of tweets is incredibly hard

## Accomplishments that we're proud of

Actually to get this thing to work.

## What's next for BeSafe

Better UI/UX and maybe a predictive capability.
