Care By Circles

Human judgment consensus in Circles counterplay the effects of technology that connects us, but also polarizes, monetizes, manipulates, and controls us.

What it does

Help communities at a time of their greatest need, to go from vulnerable to resilient. How? By using human judgment!

  • When you are in need, ask your Circle for help just by pushing a button
  • Information is only shared within the Circle
  • Your Circle is limited in size (150 people, Dunbar’s number)
  • Everyone in the Circle may give you support.
  • Everyone is incentivized

How we built it

Iteratively Top-Down and Bottom-Up

Challenges we ran into

Timezone difference, working culture, regtest peculiarities like mining and being local. Scalability issue when massively calling an Oracle, that can be solved.

Accomplishments that we're proud of

Using Bitcoin for smart contracts and make it user-friendly

What we learned

  • Working together in an international team (The Netherlands, China and India)
  • Using Bitcoin for smart contracts

What's next for Care By Circles

Foreseen, but to be implemented is:

  • A good FIFO queue for handling massive locked queries to the Oracle
  • Asking for help
  • Expelling a member of a Circle by majority
  • The concept is blocklchain agnostic, its implementation, can be made in RGB, Rootstock and even in Ethereum, but for the moment we will use a BTC fork (see the powerpoint for further reasoning) (we also considered counterparty or Elements, but scripts are not easily programmable in a client)
  • When we will fork the BTC blockchain. current BTC holders will already have some Circle tokens,
  • Related to that: we need to think about replay protection
  • Some tokens are 'freed' to be spent, such as the miner fee. They are not locked by the Oracle. The Oracle guards, via the agreed contract, the other remaining tokens.
  • Unique identification of a person, for now this always returns true, see below
