Wabisabi Deanonymization Vulnerability “Disclosed”
GingerWallet, the fork of WasabiWallet maintained by former zkSNACKs employees after the shut down of the Wasabi coinjoin coordinator, has received a vulnerability report from developer drkgry. This vulnerability would allow the total deanonymization of users inputs and outputs in a coinjoin round, giving a malicious coordinator the ability to completely undo any privacy gains from coinjoining by performing an active attack.
Wasabi 2.0 was a complete re-design of how Wasabi coordinated coinjoins, moving from the Zerolink framework utilizing fixed denomination mix amounts, to the Wabisabi protocol allowing dynamic multi-denomination amounts. This process involved switching from homogenous blinded tokens to register outputs to claim your coins back, to a dynamic credentials system called Keyed Verification Anonymous Credentials (KVACs). This would allow users to register blinded amounts that prevented theft of other users’ coins without revealing to the server plain-text amounts that could be correlated and prevent linking ownership of separate inputs.
When users begin participating in a round, they poll the coordinator server for information regarding the round. This returns a value in the RoundCreated parameters, called maxAmountCredentialValue. This is the highest value credential the server will issue. Each credential issuance is identifiable based on the value set here.
To save bandwidth, multiple proposed methods for clients to cross-verify this information were never implemented. This allows a malicious coordinator to give each user when they begin registering their inputs a unique maxAmountCredentialValue. In subsequent messages to the coordinator, including output registration, the coordinator could identify which user it was communicating with based on this value.
By “tagging” each user with a unique identifier in this way, a malicious coordinator can see which outputs are owned by which users, negating all privacy benefits they could have gained from coinjoining.
To my knowledge drkgry discovered this independently and disclosed it in good faith, but the members of the team who were present at zkSNACKs during the design phase of Wabisabi were absolutely aware of this issue.
“The second purpose of the round hash is to protect the clients from tagging attacks by the server, the credential issuer parameters must be identical for all credentials and other round metadata should be the same for all clients (e.g. to ensure that the server isn’t trying to influence clients to create some detectable bias in registrations).”
It was brought up in 2021 by Yuval Kogman, also known as nothingmuch, in 2021. Yuval was the developer to design what would become the Wabisabi protocol, and one of the designers in actually specifying the full protocol with István András Seres.
One final note is the tagging vulnerability is not actually addressed without this suggestion from Yuval as well as full ownership proofs bound to actual UTXOs as proposed in his original pull request discussing tagging attacks. All of the data being sent to clients isn’t bound to a specific round ID, so a malicious coordinator is still capable of pulling a similar attack by giving users unique round IDs and simply copying the necessary data and re-assigning each unique round ID per-user before sending any messages.
This is not the only outstanding vulnerability present in the current implementation of Wasabi 2.0 created by the rest of the team cutting corners during the implementation phase.
A major vulnerability in Wabisabi has been publicly revealed that would allow a malicious coordinator server to deanonymize users.

Why Trump Must End Capital Gains Tax On Bitcoin
In a world where digital assets are quickly becoming a cornerstone of global finance, the United States stands at a crossroads. The Trump administration has repeatedly emphasized its dedication to making everyday Americans more prosperous. From pledging to restore economic strength on the campaign trail to appointing forward-thinking advisors, the White House seems poised to usher in a new era of financial freedom. But if President Trump truly wants to supercharge wealth creation for average citizens—and establish the U.S. as the world’s leading “Bitcoin Superpower”—his administration must embrace a bold, transformative policy: eliminate capital gains taxes on Bitcoin.
The Winds of Change: Lessons from Abroad
The Czech Republic recently made headlines when its Parliament overwhelmingly voted to exempt capital gains from Bitcoin and other crypto-asset sales from personal income tax—provided they’re held for more than three years and meet certain income thresholds. This is not an isolated event. Countries like Switzerland, Singapore, the United Arab Emirates, El Salvador, Hong Kong, and parts of the Caribbean have long recognized that zero or minimal capital gains taxation on Bitcoin can help spur adoption, financial innovation, and consumer confidence.
As John F. Kennedy famously said, “A rising tide lifts all boats.” If we apply that logic to economic growth through Bitcoin, the tide is global—and it’s rising fast. In a sea awash with global liquidity and debt, America’s economic ship must navigate these digital currents. These nations’ policy choices—and their citizens’ increasing prosperity—send a powerful signal: The U.S. can and should leverage Bitcoin as a tool for growth, not burden it with outdated taxation models.
Trump’s Own Words: A Path to Prosperity
President Trump himself has indicated a willingness to rethink Bitcoin taxation. “They have them paying tax on crypto, and I don’t think that’s right,” he said in a recent interview, echoing the frustrations of millions of Americans who find it absurd to pay capital gains taxes after using Bitcoin to purchase something as small as a cup of coffee. “Bitcoin is money, and you have to pay capital gains tax if you use it to buy a coffee?” he asked rhetorically, highlighting how current laws discourage everyday transactions. He added, “Maybe we get rid of taxes on crypto and replace it with tariffs.”
This sentiment isn’t just rhetorical flourish. Trump, who spoke at the Bitcoin 2024 Conference in Nashville, proclaimed his vision for America to become the world’s “Bitcoin Superpower.” He’s also pledged to “Make Bitcoin in America,” turning the U.S. into a leading hub of Bitcoin innovation. Moreover, he appointed former PayPal Chief Operating Officer David Sacks as his ‘White House A.I. & Crypto Czar’ on December 5—a move widely seen as a step toward implementing forward-looking crypto policies.
The BITCOIN Act of 2024: A Strategic Reserve for the People
The U.S. has already taken monumental steps in this direction. The BITCOIN Act of 2024 mandates that all Bitcoin held by any federal agency be transferred to the Treasury to be held in a strategic Bitcoin reserve. Over five years, the Treasury must purchase one million Bitcoins, holding them in trust for the United States. This government-level accumulation shows a long-term vision for incorporating Bitcoin into national financial strategy. But why stop there? Eliminating capital gains tax on Bitcoin would create a positive feedback loop between national policy and personal prosperity. As the federal government invests and holds Bitcoin, private citizens could do the same without facing punitive tax obligations.
Serving the Everyday American
For everyday Americans, the cost of living and the sting of inflation were focal points of President Trump’s reelection campaign. Traditional strategies—interest rate manipulations, quantitative easing—often amount to rearranging deck chairs on a sinking ship when confronted with truly systemic economic challenges. Bitcoin offers a life raft—dare we say, a digital Noah’s Ark—for Americans trying to preserve and grow their wealth against the erosive forces of inflation. Removing capital gains taxes on Bitcoin would allow citizens to transact, invest, and save in a stable, finite asset without the drain of federal taxes on every incremental gain.
The ripple effect here is clear: More people adopting Bitcoin as a store of value and medium of exchange means stronger demand, which could further buttress the U.S. Treasury’s strategic holdings. It’s a virtuous cycle, a positive feedback loop. As Bitcoin’s value grows, so does the nation’s wealth base—helping pay down national debt, bolstering the dollar’s hegemony in global trade, and genuinely making Americans richer and more secure.
Why America Needs Bitcoin
Bitcoin is no longer a niche experiment reserved for a small band of enthusiasts. It has evolved into a mainstream, urgent priority for everyday Americans—especially the rising generation that will shape our nation’s future economy. This is not some ideological plea; it’s a practical, data-backed reality. According to the Stand With Crypto Alliance, a non-profit dedicated to transparent blockchain policies, more than 52 million Americans now own some form of cryptocurrency. Nearly nine in ten Americans believe the financial system needs updating, and 45% say they would not support candidates who stand in the way of crypto innovation. These numbers represent a sweeping, cross-partisan groundswell: Stand With Crypto’s research shows that 18% of Republicans, 22% of Democrats, and 22% of Independents hold crypto. This cuts through the usual tribal politics and points to a fundamental truth—Bitcoin is now a national policy talking point, not a side note on a fringe agenda.
The demand for America to lead is clear. 53% of Americans want crypto companies to be U.S.-based, ensuring that technological innovation and the wealth it generates remain on home soil. Among Fortune 500 executives, 73% prefer U.S.-based partners for their crypto and Web3 initiatives, signaling a corporate desire to keep America at the forefront of global financial progress.
Failing to act now risks a replay of past mistakes. America once led the world in advanced manufacturing, yet today 92% of the most sophisticated semiconductor production sits in Taiwan and South Korea. We cannot afford to cede the future financial landscape to other regions. Bitcoin isn’t just another investment class; it is the digital backbone of a rapidly evolving monetary system. If the U.S. wants to preserve its economic hegemony, maintain innovation leadership, and ensure everyday Americans have access to a stable, growth-oriented financial future, it must embrace Bitcoin wholeheartedly. In doing so, the nation can secure its place as the global Bitcoin superpower—uplifting our citizens, strengthening our economic base, and safeguarding our strategic interests in the 21st-century digital economy.
America, Charting the Course
By aligning with global best practices and enacting forward-thinking policies, the U.S. can position itself as a beacon of financial liberty and technical innovation. Eliminating capital gains tax on Bitcoin would signal to investors, entrepreneurs, and everyday citizens that America is serious about leading in the 21st century’s digital economy. It’s not just about being “Bitcoin-friendly”; it’s about ensuring that average Americans have the tools they need to navigate turbulent economic waters.
The complexity and inefficiency of taxing every digital transaction is an unnecessary burden on innovation and everyday life. Americans deserve better—they deserve the freedom to transact in a digital world without punitive oversight.
In essence, this is America’s chance to do what it has always done best: innovate, adapt, and lead. Removing capital gains taxes on Bitcoin wouldn’t just fulfill a campaign promise; it would set the stage for long-term prosperity, empower citizens to secure their financial futures, and cement the United States as the world’s foremost Bitcoin champion. A rising tide, indeed, lifts all boats—and what better vessel to embark upon than a Bitcoin Ark, captained by a visionary administration determined to truly Make America Great Again?
This article is a Take. Opinions expressed are entirely the author’s and do not necessarily reflect those of BTC Inc or Bitcoin Magazine.
By eliminating capital gains taxes on Bitcoin, the Trump administration can spur U.S. innovation, strengthen the nation’s economic sovereignty, and ensure everyday Americans gain equal footing in the world’s rapidly evolving digital economy.
