A little trust goes a long way: Preserving fuzzy anonymity in decentralized credit networks

Credit networks are a type of decentralized payment infrastructure with no central currency, but where nodes extend each other various amounts of credit, using IOUs whose value depend on the trust between the transacting nodes. An independent and anonymity-preserving alternative to traditional payment systems in theory, actual implementations of credit networks so far have relinquished anonymity, and sometimes also decentralization, in order to overcome the risk of Sybil attacks. We suggest a possible implementation of credit networks that combines a fuzzy notion of anonymity and trust with a decentralized and localized system to achieve resistance to Sybil attacks.


About Reversim

Reversim (רברס עם פלטפורמה) is a Hebrew podcast by Ori Lahav and Ran Tavory which brings together software developers and product, with over 300 recorded episodes and a few thousands listeners.

The summit is our intention to create a conference for developers by developers. Like in the podcast, we bring you the content we are interested in, and we hope you will be too.
