Transit - Pension Plan

Github Repo: https://github.com/team-harold/ethberlinzwei Presentation: https://github.com/team-harold/ethberlinzwei/blob/master/Transit_PensionPlan.pdf

Inspiration

How could blockchain and Ethereum add value to a traditional pension plan? Is it possible and what are the benefits of it?

What it does

Our project is a fully decentralized webapp (no backend!) and a smart contract on the testnet featuring the payment process for a pension plan. The frontend offers a payment plan with customizable options based on the smart contract. With a random "death oracle" it simulates with accelerated time how pensions would work in real life.

How we built it

We built it using Solidity, Javascript.

Challenges we ran into

Actuarial mathematics is cumbersome on an integer only system like the EVM.

Accomplishments that we're proud of

We implemented a working algorithm that calculates the present value of future pay outs and build a fully functional webapp. That's how traditional retirement products calculate their premiums.

What we learned

So many things!

What's next for Transit - Pension Plan

We would like to dive deeper into the issue of pension plans on blockchain and start a real world experiment (one "real" week equals simulated "two" years) with 300 participants.

Bounties

We would like to apply to the Consensys Social Impact Challenge
