Tornado Cash Co-Founder Alexey Pertsev Denied Bail by Dutch Court
"Pertsev sought bail to allow him to prepare for his appeal to the verdict in May which found him guilty of money laundering.
Alexey Pertsev was denied bail by a Dutch court on Friday, according to DLNews.
Pertsev's lawyers were seeking bail to allow the Russian to prepare for his appeals process"

In Russia, there is such a term as “social justice” in prison punishment. If the sentence is passed, appeals will be useless unless there are very serious grounds.
This means that a convicted person must spend 50-70% of the court-ordered term in prison and have no violations in order to qualify for a transfer to a penal colony with milder conditions or to qualify for conditional early release.

Tornado Cash Developer Alexey Pertsev Found Guilty, Sentenced to 64 Months in Prison by Dutch Court

"Alexey Pertsev was first jailed in the Netherlands in August 2022.
Tornado Cash developer Alexey Pertsev was sentenced to 64 months in jail for money laundering
"Tornado Cash does not pose any barrier for people with criminal assets who want to launder them," according to the translated verdict seen by CoinDesk."

Tornado Cash co-founder requests dismissal of money laundering charges
"Roman Storm’s lawyers argued that the charges are “fatally flawed” and must be dismissed, given “there was nothing” Storm could have done to prevent sanctioned entities from using the crypto mixer.
Roman Storm, co-founder of cryptocurrency mixer Tornado Cash, has filed a motion to dismiss all three charges against him that allege he operated a money laundering business and violated the International Emergency Economic Powers Act.

“By no stretch can Mr. Storm be deemed to have conspired to launder funds,” Storm’s lawyers stated in a March 29 filing in the United States District Court for the Southern District of New York.

Storm’s lawyers argued that Tornado Cash was developed, “became immutable” and publicly available before it was used by the hacking groups sanctioned by the U.S. Department of the Treasury.

Therefore, by the time of the alleged misconduct, there was allegedly little that Storm could do to prevent a “sanctioned entity from using it.”

The charges are centered around Tornado Cash allegedly facilitating the efforts of the North Korean Lazarus Group bypassing U.S. sanctions, allowing the country’s regime to reportedly fund its nuclear program."

Absolutely right.

Meanwhile, I take back my past statement. It looks like America's Most hated hackers, the Lazarus group, have been bombarding other mixers with their stolen funds. One of those mixers was a bitcoin mixing service known as Yomix
It's just a matter of time before we hear about another Mixer seizure or sanction.

The mixer web interface does not work, but the smart contract will live as long as the blockchain is running.

Dutch Prosecutors Seek 64-Month Jail Sentence for Tornado Cash Dev Alexey Pertsev
The judge will deliver the verdict on May 14, the court said.
"Prosecutors seek to sentence Tornado Cash developer Alexey Pertsev to 64 months in jail, members of their team told CoinDesk.
The consequences of the trial could have wider implications on how developers of open-source projects are treated."

So the mixer still works after all 
I remember having an argument with someone who claimed that the mixer was no longer functional. What he didn't probably know is that it's a smart contract of sorts, which is immutable as long as the blockchain it's built on is working.

It however looks like the hackers don't know about the existence of other reliable bitcoin mixers?

Binance still plays a major part in the cryptocurrency scene, so the token delisting will surely affect the market. I believe due to regulatory pressure, even though it is not a direct way to adress this particular token, they feel pressured to delist such kind of token. Not to mention this particular platform is sanctioned and you know the story. So, it is likely they did it for purposes.

Regarding the token itself, surely the liquidity will not be like before, but if there are still an usecases within the platform, I'm sure the token will hold on.

That day they delisted a number of other tokens that also dumped so hard. The coins including waltonchain, Bitshares, PERL. I am not sure if the delisting comes at a time when Binance is under fire from the regulators, or this is just their routine.

I am actually surprised that TORN was still trading on the exchange after all this time.

https://cointelegraph.com/news/tornado-cash-token-falls-binance-announces-delisting
"Tornado Cash is a cryptocurrency mixing protocol, and TORN is used to vote on proposals for upgrading the protocol. From Nov. 26 to 27, the token took a nosedive, falling from $3.90 to just $1.66 — a decline of 57%. The price decline happened as the world’s largest crypto exchange by volume, Binance, announced that it would stop accepting deposits of TORN on Dec. 8 and no longer process withdrawals after March 7, 2024."

Tornado Cash Founders Indicted For $1B Crypto Laundering — 1 Arrest, 1 At Large
"The founders of Tornado Cash, Roman Storm and Roman Semenov, have been indicted for allegedly operating a cryptocurrency mixer that laundered more than $1 billion, including funds from the notorious North Korean cybercrime group, Lazarus Group.

U.S. Attorney Damian Williams said that Tornado Cash was an infamous cryptocurrency mixer that laundered more than $1 billion in criminal proceeds and violated U.S. sanctions. "

Roman Semenov was placed on OFAC’s sanctioned persons list, and Roman Storm was arrested as the United States continued its crackdown on the crypto mixer.

https://u.today/tornado-cash-reigns-supreme-on-ethereum
"Despite facing sanctions from the U.S. Treasury in August 2022, Tornado Cash continues to dominate as the premier crypto mixer on the Ethereum network.  Recent data from crypto analytics firm Arkham reveals that a staggering $77.35 million in assets passed through Tornado Cash contracts on the Ethereum Mainnet in just the last month.
An impressive comeback   The mixer, which operates across seven different chains, has made a name for itself by allowing users to obfuscate transfers of ten distinct crypto assets, with native ETH on the Ethereum mainnet being the most popular.  At its height in July 2021, Tornado Cash managed more than $700 million of ETH in its pool contracts. The platform did experience a significant setback post-sanctions, with assets plummeting by over 60% and a substantial decrease in transfer volume. "

A group of crypto investors and developers lost a lawsuit funded by Coinbase that sought to argue the U.S. Treasury Department overstepped its authority in sanctioning Tornado Cash, a mixing service designed to make crypto transactions anonymous.
Tornado Cash is an actual entity in itself, which has a property interest in its smart contracts, wrote Judge Robert Pitman, from the U.S. District Court for the Western District of Texas, on Thursday.

It's a privacy mixer. You just make a list of the "rules" in this application and they'll set something like the following: **"you must not link the links on the application to another application,"** so if I want to use this "we have to check it first" and then if I don't like the link, I won't go into the application.

https://watcher.guru/news/tornado-cash-developer-alex-pertsev-to-be-released-from-prison
Tornado Cash Developer Alex Pertsev To Be Released From Prison
"Alex Pertsev, a developer of Tornado Cash, will soon be released from prison. Pertsev spent nearly nine months behind bars. The developer was detained by Dutch officials in August 2022. He was accused of participating in money laundering through the Tornado Cash cryptocurrency mixer.
According to reports, Pertsev will be released on April 26, which is also his birthday. However, the developer is far from being cleared of charges. Pertsev is currently facing suspended release under surveillance. He will be under surveillance while he awaits trial from home. Pertsev would be placed under surveillance with an ankle monitor during the suspended release period."

CEO Kraken Powell called the actions of the US Treasury Department to block Tornado Cash unconstitutional, according to him, and it's hard to disagree with him here, people have the right to financial confidentiality. The actions of the US Treasury Department were a reflection on the collapse of Terra Luna and occurred more likely mechanically than meaningfully.

It is also reported that the Coin Center advocacy group is considering appealing the US sanctions against Tornado Cash in court because it believes that OFAC exceeded its authority by imposing sanctions against the "autonomous program code", and not against individuals.

The following entity has been added to OFAC's SDN List:

"READ THIS THREAD OR GO TO JAIL FOR 30 YEARS (sorry not kidding)

Tornado Cash added to US sanctions list - $437m of assets blocked.

What is OFAC, what are sanctions, and what does this mean for DeFi 👇"

Yeah privacy protocol must do that in order to keep them safe from the regulators or even interpol. We do know that how many hackers and criminals are using this to mixing their ethereum that stolen from others. This is good to see that if they are blocking the address and it can't be moved to the somewhere. that means what have said by CEO of tornado cash was not true as they are still having control over this protocol. So, it's good to see that hacked have no way to withdraw their money.

The case related to the Ronin attack caused the most damage to the crypto industry to date, the amount of money stolen amounted to 622 million USD. Tornado claims to still respect the privacy of its users but will not stay silent before criminals, so it has decided to interfere in transactions related to the wallet address that attacked Ronin.
I think their decision is right, if no action is taken more criminals will take advantage of this loophole to directly launder illegal money.

This project called Tornado Cash was supposed to be a privacy coin but I heard they block a hacker's ETH address, should privacy coins be doing this? Haven't this move broken some protocol of this project and its utility itself?.

Never heard or tried this one but looks decent but I'm just curious about the tx fee. Privacy is one of the issue of we have in cryptocurrency and I think this could be a good alternative but there are also some good alternative such as selling ethereum for other currency I think there are some services that allows us to exchange one currency to another without logging in or KYC but I think they can't handle big transactions.

So you mean either the tornado owner gave up details still the address couldny possibly be a way to trace the scammer since they could use another mixer or already did a mixer prior to using tornado cash? Anyway thats absurd. Im sure there are ways like the address used sending tokens to somewhere comnected such as exchange right? But actually this is a very sensitive case cause might the address falls on other guys who are innocent and only been used to show.

I think that the intention behind why tornado cash was created in the first place is good, however, just like many other things it is being taken advantage and used for illicit things. I just hope that there could be processes and protocols when it comes to transactions being suspect under scam activities, without breaking the privacy rights and terms of users of course.

It's the first time I have heard of it, but I'm not surprised that there's something like that for the Ethereum network. It's about time, probably for that to happen. I'm not sure how much it is being used because I know many hacks and scams are being done with different tokens, etc. It's the go-to thing for scammers for sure.

If I was involved in crime, I would not bet on only 1 project. Even if the protocol is secure, there are many other ways to find the right traces of a scammer. I would exchange the received ethereum for monero and use another mixer. But for personal privacy, this is a great project.

Btw, is there anyway the owners of tornado cash, can track those wallets that has been sent to them. For example there is a confirmed scammer who exploited funds used their services. Is there a chance they could turn over the resulting wallets to authority to help the victims of the exploited community or its not possible even with the owner. It seems theu could help as lonh as they give details of the users wallet.

Tornado Cash is one of the best services.

Tornado Cash Co-Founder Says the Mixer Protocol Is Unstoppable
Roman Semenov says Tornado Cash is designed so a third-party can’t control it.
https://www.coindesk.com/tech/2022/01/25/tornado-cash-co-founder-says-the-mixer-protocol-is-unstoppable/

I wanted to test their service but ran into a problem... my emails are not reaching them.

So I think everyone should refrain from using Tornado Cash for a while. 

Probably works like btc in chipmixer. I never tried it yet but seen a lot of youtubes tutorials about using it. Works simply to hide their transactions and become totally anonymous. This is the favorite dapp probably of all scammers who doing rug pull and some scam projects.

But surprisingly that their tokens has been used and listed even on Binance.

Tornado Cash Has Been Deployed on Optimism
https://tornado-cash.medium.com/tornado-cash-has-been-deployed-on-optimism-68351443bbc
"With this latest addition, Tornado Cash currently functions on Ethereum, Binance Smart Chain, Polygon, xDAI Chain, Avalanche, Arbitrum and, last but not least, Optimism."

Tornado Cash has deployed the beta version of the Nova pool, now it is possible to deposit and withdraw arbitrary amounts of ETH, currently the beta version limits the transfer amount to 1 ETH, the minimum withdrawal amount judging by the site data is 0.1 ETH.
https://nova.tornadocash.eth.link/

The team of the Tornado Cash Ethereum mixer announced its readiness for integration with the second-level network service Arbitrum One. Integration will provide users with all the benefits of L2 solutions, including cheaper transactions.

tornado cash is already a protocol and is being used for anonymity on the ethereum network. It looks pretty new to all of us, but it does exist and has 5,000 followers on their twitter page: https://twitter.com/tornadocash
This is their website: https://tornado.cash/

There's a big difference between anonymity and privacy. As we move more towards regulation we can expect the shift more towards privacy and away from anonymity.

You can say that to bitcoin mixer as well, wherein criminals can used it to hide their footprints.

I think those mixers are for privacy and anonymity, it' just it is being taken advantage by scammers and/or criminals, terrorists, drug peddlers.

As for this Tornado Cash, I'm sorry I'm not familiar and base on the response, it is not well known in this community. But it's good if we have this kind of Ethereum mixer though, I think many tried to built one in the past, but it was not successful.

ICO defi scammers are using Tornado to steal fund raised, I read it makes them anonymous. The anonymity is good but if one can't always trace criminals, it becomes a very big issue to the socity.

It is a mixer that keeps ethereum users anonymous on strong ethereum. Recently the YBDAO project has raised 7500ETH and they have submitted an unannounced Tornado Cash. It was a scam project and they were safe with the money they raised. I think this is an illusion like the way that mixers help bad guys use bitcoin for illegal activities.

Anyone heard of this? (https://tornado.cash/)

It's supposed to be a Ethereum privacy mixer, I haven't try it, so for those who have used it already, can you share your experience with this application?

They supposedly used zkSNARK ((Zero-Knowledge Succinct Non-Interactive Argument of Knowledge,) technology).
