TandaPay Progress Thus Far

Easy to bootstrap, scalable, peer to peer insurance, which doesn’t require 98% of users to know they are using cryptocurrency

I have been researching peer-to-peer insurance architecture for more than five years now. My first whitepaper entitled “Peer-to-peer insurance on an Ethereum blockchain” was posted to the Ethereum subreddit February 2015 prior to Ethereum’s launch. Since that time I have published more than 100,000+ words on the topic of peer-to-peer architecture with the majority of that content being focused on insurance.

  1. Claims are parametric and linked to triggering events which release a known payment amount, making awards both fairer and simpler.
  2. TandaPay groups leverage a policyholder’s existing social network of friends and family to form a community which awards claims.
  3. Blockchain technology exempts members from all forms of insurance regulation. Payments are never held by a third party and premiums move directly from policyholders to claimants. In TandaPay, there is never a custodian who assumes the liability of managing member funds.
  4. Fairness is mandated by the protocol and uses zero-fraud architecture which provides policyholders with the highest level of protections.


My motivations for working on this project are described here:

Key Technical Findings and Practical Applications

The core of my findings are written down in these posts. The first post explains why P2P insurance is a natural evolution of existing technologies. The second post is the most valid use case I’ve found for peer-to-peer insurance. The third and fourth posts convey the foundation of the architecture in just under 5,000 words. These posts function to give everyone a broad overview of how TandaPay works without getting mired in unnecessary details:

The Importance of MakerDAO’s DAI

I have started a series on stablecoins since TandaPay is required to use a stablecoin to function. We look forward to integrating with MakerDAO to allow policyholders to pay their premium payments in DAI and receive their claim awards in DAI. This will provide a better user experience since users will not be exposed to the volatility associated with using ETH.

Finally I wrote one post which which offers a very sentimental take on how blockchain based insurance will allow people to achieve a special type of immortality:

Update: TandaPay can provide paid sick leave coverage

The US government’s present response to the coronavirus crisis has left more than 10 million people without paid sick leave coverage. We have to do better.
