A new semi-permissionless privacy tool, Privacy Pools, has launched on Ethereum, allowing users to transact privately while proving their funds aren’t linked to illicit activities.
The privacy tool, launched by Ethereum builders 0xbow.io on March 31, earned support from the likes of Ethereum co-founder Vitalik Buterin, who not only backed the privacy project but made one of the first deposits on the platform.
0xbow.io said that it implements “Association Sets” to batch transactions into the anonymous Privacy Pools and that a screening test is conducted to ensure that those transactions aren’t linked to illicit actors, such as hackers, phishers and scammers.
gm Ethereum ☀️
It is our great honor to announce the mainnet launch of Privacy Pools!
ETH users can now achieve on-chain privacy, while still dissociating from illicit funds
It is now up to all of us to Make Privacy Normal Again 🫡
The Association Sets are “dynamic” — meaning that if a transaction is admitted but later found to be illicit, it can be removed from the set without disrupting any other deposits, 0xbow.io said.
If a deposit is disqualified, the user can click the “ragequit” function to return the funds to their original deposit address.
The innovation is part of 0xbow.io’s vision to “Make Privacy Normal Again” while also attempting to achieve regulatory compliance.
Privacy protocols have received considerable backlash from regulators in recent years due to their increasing use by illicit actors to launder funds.
One of those privacy tools, Tornado Cash, was sanctioned by the US Treasury’s Office of Foreign Assets Control (OFAC) between August 2022 and March 2025 after it was linked to around $7 billion laundered by the North Korean state-backed Lazarus Group.
0xbow.io also praised Buterin, Chainalysis Chief Scientist Jacob Illum, and two academics at the University of Basel in Switzerland for crafting a September 2023 white paper outlining how Privacy Pools could be built.
0xbow.io strategic adviser Ameen Soleimani also contributed to the paper, which has seen over 12,000 downloads and has been cited in nine other papers.
The Privacy Pool code also passed a successful audit from Audit Wizard. a smart contract auditing firm co-founded by former Apple engineer Joe van Loon.
More than $41 billion worth of illicit transfers were made in 2024, which made up 0.14% of total onchain volume for the year, according to the Chainalysis 2025 Crypto Crime report published on Jan. 15.
While it marked around an 11% fall from 2023, Chainalysis said that figure could climb to around $51 billion as more criminal-tied addresses are found.
Lawmakers in the US states of Minnesota and Alabama filed companion bills to identical existing bills that if passed into law, would allow each state to buy Bitcoin.
The Minnesota Bitcoin Act, or HF 2946, was introduced to the state’s House by Republican Representative Bernie Perryman on April 1, following an identical bill introduced on March 17 by GOP state Senator Jeremy Miller.
Meanwhile, on the same day in Alabama, Republican state Senator Will Barfoot introduced Senate Bill 283, while a bi-partisan group of representatives led by Republican Mike Shaw filed the identical House Bill 482, which allows for the state to invest in crypto, but essentially limits it to Bitcoin (BTC).
Twin Alabama bills don’t explicitly name Bitcoin
Minnesota’s Bitcoin Act would allow the state’s investment board to invest state assets in Bitcoin and other cryptocurrencies and permit state employees to add crypto to retirement accounts.
It would also exempt crypto gains from state income taxes and give residents the option to pay state taxes and fees with Bitcoin.
The twin Alabama bills don’t explicitly identify Bitcoin, but would limit the state’s crypto investment into assets that have a minimum market value of $750 billion, a criterion that only Bitcoin currently meets.
26 Bitcoin reserve bills now introduced in the US
Introducing identical bills is not uncommon in the US and is typically done to speed up the bicameral legislative process so laws can pass more quickly.
Bills to create a Bitcoin reserve have been introduced in 26 US states, with Arizona currently the closest to passing a law to make one, according to data from the bill tracking website Bitcoin Laws.

Pennsylvania was one of the first US states to introduce a Bitcoin reserve bill, in November 2024. However, the initiative was reportedly eventually rejected, with similar bills also killed in Montana, North Dakota, South Dakota and Wyoming.

According to a March 3 report by Barron’s, “red states” like Montana have faced setbacks to the Bitcoin reserve initiatives amid political confrontations between the Democratic Party and the Republican Party.
Update (April 3, 5:43 am UTC): This article has been updated to add information on the STABLE Act and GENIUS Act.
The US House Financial Services Committee has passed a Republican-backed stablecoin framework bill, which will now head to the House floor for a full vote.
The Committee passed the Stablecoin Transparency and Accountability for a Better Ledger Economy, or STABLE Act, with a 32-17 vote on April 2, with six Democrats voting in favor.
The bill was introduced on Feb. 6 by committee Chair French Hill and the chair of its Digital Assets Subcommittee, Bryan Steil — reportedly drafted with the help of the world’s largest stablecoin issue, Tether.
The bill would provide rules around payment stablecoins, a crypto token tied to a currency such as the US dollar, and aims to ensure issuers give information about their business and how they back their tokens.
During an earlier markup session, the committee’s leading Democrat, Maxine Waters, who later voted against the bill, criticized her Republican peers for “setting an unacceptable and dangerous precedent” with the STABLE Act.
She said President Donald Trump could use the bill to allow his family’s stablecoin to be used in government payments, and argued the bill validates Trump “and his insiders’ efforts to write rules of the road that will enrich themselves at the expense of everyone else.”
In late March, the Trump family’s World Liberty Financial crypto venture launched a stablecoin, World Liberty Financial USD (USD1). Meanwhile, the US Housing Department, which oversees social housing, was reportedly looking to experiment with using stablecoins for some of its functions.
Stablecoin GENIUS Act also weaves through Congress
Other stablecoin-related bills are also working their way through Congress, including the Republican-led Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, which lays out oversight and reserve rules for issuers.
The US Senate Banking Committee voted through the GENIUS Act in an 18-6 vote on March 13, after Senator Bill Hagerty, one of the bill’s co-sponsors, updated it following consultation with the Committee’s Democrats.
Before the vote, Democratic Senator Kirsten Gillibrand said the updated GENIUS Act made “significant improvements to a number of important provisions” in areas such as consumer protections and authorized stablecoin issuers.
Both the STABLE Act and GENIUS Act will now wait until debate time on the floor of the House and Senate, respectively, before they head for a floor vote.
Crypto journalist Eleanor Terrett reported on X that two unnamed crypto lobbyists said there is likely to be “a coordinated push behind the scenes over the next few weeks to get the two bills to mirror each other, as there are still some differences between them.”
Doing so would “avoid having to set up a so-called conference committee which is formed so members from both chambers can negotiate to create a final version of the bill everyone agrees on,” she added.
Tulip Siddiq has told Sky News her “lawyers are ready” to handle any formal questions about allegations she is involved in corruption in Bangladesh.
Asked whether she regrets apparent links with the Bangladeshi Awami League political party, Ms Siddiq said “why don’t you look at my legal letter and see if I have any questions to answer… [the Bangladeshi authorities] have not once contacted me and I’m waiting to hear from them”.
Lawyers acting for Ms Siddiq wrote to the Bangladeshi Anti Corruption Commission (ACC) several weeks ago saying the allegations were “false and vexatious”.
The letter said the ACC must put questions to Ms Siddiq “by no later than 25 March 2025” or “we shall presume that there are no legitimate questions to answer”.

Staff from the NCA visited Bangladesh as part of initial work to support the interim government in the country.
In a post online today, the former minister said the deadline had expired and the authorities had not replied.
Sky News has approached the Bangladeshi government for comment.
The allegations against Ms Siddiq are focused on links to her aunt Sheikh Hasina – who served as the prime minister of Bangladesh for 20 years.
She is accused of becoming an autocrat, with politically-motivated arrests, extra-judicial killings and other abuses allegedly happening on her watch. Hasina claims it’s all a political witch hunt.
Ms Siddiq was found to have lived in several London properties that had links back to the Awami League political party that her aunt still leads.
She referred herself to the prime minister’s standards adviser Sir Laurie Magnus who said he had “not identified evidence of improprieties” but added it was “regrettable” Ms Siddiq had not been more alert to the “potential reputational risks” of the ties to her aunt.
Ms Siddiq said continuing in her role would be “a distraction” for the government but insisted she had done nothing wrong.
