Idena - Proof of Person Blockchain
-
In proof of stake voting power depends on the amount staked
In proof of work voting power depends on the computing powerConsensus mechanisms based on these lead to plutocracy
To avoid this a different resource which can be distributed across all people is required.
In IDENA every participant has equal voting power and mining income.
To prove your personhood, no personal data is needed.
Individuals prove their uniqueness by solving a series of flip tests.
AI resistant, strict interval flip tests do not allow algorithmic bots to pass and (they claim) it is difficult to create many by humans.
(From my understanding, they make you appear online at a specific time, mornings in USA, afternoons in Europe and nights in ASIA where you have to solve thee flip tests within a very tight schedule. If you are a person owning 2-3 “accounts” you cannot do these at the same time.
