Petar Maymounkov, one of the original authors of [[Kademlia]], has proposed a way to circumvent the weakness to the Sybil attack by incorporating social trust relationships into the system design.<ref>{{citeCite journal |authorlast=Chris Lesniewski-Laas |first=Chris |date=2008-04-01 |title=A Sybil-proof one-hop DHT |pages=20 |url=httphttps://pdosdl.csailacm.mit.eduorg/papersdoi/sybil-dht-socialnets0810.pdf1145/1435497.1435501 |access-datejournal=2018-02-16Proceedings of the 1st Workshop on Social Network Systems |archive-dateseries=2017-05-15SocialNets '08 |archive-url___location=https://webNew York, NY, USA |publisher=Association for Computing Machinery |pages=19–24 |doi=10.archive.org1145/web/20170515220528/https://pdos1435497.csail.mit.edu/papers/sybil-dht-socialnets08.pdf1435501 |urlisbn=978-status=live 1-60558-124-8}}</ref> The new system, codenamed Tonika or also known by its ___domain name as 5ttt, is based on an algorithm design known as "electric routing" and co-authored with the mathematician Jonathan Kelner.<ref>{{cite journal |author=Jonathan Kelner, Petar Maymounkov |title=Electric routing and concurrent flow cutting |url=https://archive.org/details/arxiv-0909.2859 |arxiv=0909.2859|bibcode=2009arXiv0909.2859K|year=2009 }}</ref> Maymounkov has now undertaken a comprehensive implementation effort of this new system. However, research into effective defences against Sybil attacks is generally considered an open question, and wide variety of potential defences are proposed every year in top security research conferences.{{Citation needed|date=May 2020}}
