– Samourai Wallet accuses Wasabi Wallet of running a „psyop“ through their educational project Coinjoins.org.
– Samourai claims that Coinjoins.org is designed to make users forget about Wasabi’s recent announcement to create a „compliant coinjoin.“
– Samourai also points to the PlusToken ponzi scheme and claims that Wasabi’s mixing protocol was broken and led to the deanonymization of the scheme.

Samourai Wallet Accuses Wasabi Wallet of Running a „Psyop“

Samourai Wallet, a software wallet known for enhancing Bitcoin privacy through mixing, has accused its main competitor Wasabi Wallet of running a „psyop“ through their educational project Coinjoins.org. In a lengthy Twitter thread, Samourai claims that Coinjoins.org is designed to distract users from Wasabi’s recent announcement to create a „compliant coinjoin.“

Claim about Wasabi’s Mixing Protocol and PlusToken Scam

Samourai also points to the PlusToken ponzi scheme and claims that Wasabi’s mixing protocol was broken, leading to the deanonymization of the scheme. According to Samourai, the PlusToken scam saw their mixing deanonymized „due to the broken Wasabi mixing protocol.“ In an analysis of the PlusToken scam, OXT Research detected abnormally high address reuse among Wasabi mixer outputs, which led to the discovery of an active Sybil attack on the Wasabi mixer. The source of the Sybil attack traced back to addresses reportedly controlled by PlusToken.

Criticisms against Wasabi’s CoinJoin Implementation

In addition, OXT Research’s analysis of various cases, including the North Korean Lazarus Group, the KuCoin hack, and the Hydra deep web black market, cited the poor quality of Wasabi’s CoinJoin implementation. These findings suggest that Wasabi’s CoinJoin implementation may have privacy shortcomings and could be vulnerable to deanonymization attacks.

Samourai’s Discoveries and Wasabi’s Response

Samourai further claims that it discovered that Wasabi’s coin selection algorithm for CoinJoin was deterministic and predictable in 2020, which nullified any anonymity gained. Wasabi reportedly refuted this claim but silently patched the issue later.

Close Ties between Samourai and OXT Research

It is worth noting that all the findings criticizing Wasabi’s privacy implementation come from OXT Research, a research group that works closely with Samourai developers to test and create techniques that mitigate privacy shortcomings. This close relationship raises questions about potential collusion between Samourai and OXT Research.
