We would like to present our latest paper on an empirical study of Idena protocol (idena.io). The paper titled “Compressed to 0: The Silent Strings of Proof-of-Personhood" is co-authored by Puja Ohlhaver, me, the founder of Idena, and Paula Berman.

The paper highlights the flaws of Proof-of-Personhood, which prompted the Idena protocol to pivot towards "sublinear identity staking”. The findings will undoubtedly serve as the foundation for the next generation protocols proposing Sybil-resistant and collusion-resistant forms of consensus.
