Abstract

This work proposes StakeNote, a distributed ledger protocol that combines Proof-of-Stake (PoS) with privacy and anonymity preserving payments. The protocol combines Ouroboros Praos, a provably secure PoS protocol, with CryptoNote, a privacy-preserving payment system based on ring signatures which has been widely used in practice. We prove that StakeNote inherits the security guarantees of Ouroboros Praos and the privacy guarantees of CryptoNote and we demonstrate its practicality via a proof of concept implementation, where block creation requires less than 25 ms and eligibility proofs are approx. 3 KB for anonymity sets of size 16. Finally, we discuss heuristic enhancements that potentially increase privacy and enable dynamic participation.
