Haseeb Qureshi: Chilling paper on how to deanonymize Ethereum mixer users by @badcryptobitch et al. In short, mixer users are leaking entropy by: 1. transacting at the same times of day 2. using consistent gas prices (whether manual or by wallet algos) 3. address reuse https://arxiv.org/pdf/2005.14051.pdf https://t.co/JeTYPz7kWz

Péter Szilágyi: I haven't read the paper yet, but these kinds of papers are super important for the #Ethereum ecosystem. We all like to talk about out achievements and how far we've come, but it's equally important to recognize and talk about our current weaknesses.

Aaron Wright: Blockchain tech is far from private. Great research exploring lack of privacy on Ethereum: https://arxiv.org/pdf/2005.14051.pdf That’s why projects like @TornadoCash are important. Financial privacy is a norm, today, and without technical enhancements, we may lose it as blockchains scale

Frank Topbottom: Currently, there are 1312 unique addresses that deposited 0.1 ETH into Tornado. Of these, 112 made at least 5 deposits. In addition, the number of addresses can be reduced by using heuristics from this paper: https://arxiv.org/pdf/2005.14051.pdf It will be cool if someone takes a look at it.

HOPR | hoprnet.eth: Privacy on Ethereum is not as easy as it may seem, even with @TornadoCash Your dapp usage or gas pricing might leak enough metadata to deanonymize you But Ethereum also does not provide network-level privacy to protect the origin of your tx. HOPR fixes that. #privacy #ethereum

zooko: What's most exciting about the future? Holmes: network-layer privacy. The Zcash team seems committed to leading on that. https://www.coindesk.com/videos/foundations-consensus-distributed/foundations-zcash-electric-coin-company (BTW, this new research that just came out is relevant: https://twitter.com/Istvan_A_Seres/status/1266192703307632649)

Vortex ⚡🌊: TLDR; #Ethereum doesn't care much about privacy when it's trivial to deanonymize tens of thousands of users. https://twitter.com/Istvan_A_Seres/status/1266192703307632649

Duke Leto: Looks like the season of de-anonymization papers! Profiling and Deanonymizing $ETH Users by @badcryptobitch and others look like a fun read. And yeah, blockchain is watching you. Ethereum has no privacy.
