Etica is a blockchain protocol for open source medical research that encourages multiple parts to take part in a decentralised medical research process without any intellectual property. The protocol is based on a privacy voting system in which token holders can submit proposals. The proposals are scientific articles oriented towards a specific disease. The protocol impels off-chain communications between token holders about proposals usefullness. Etica aims to become the neutral protocol on top of which the next generation decentralised communities will organise themselves and gain expertise to discover medical treatments without intellectual property.
