Abstract

Terraform Labs co-founder Do Kwon has been sentenced to 15 years in prison by a U.S. court after pleading guilty to wire fraud and conspiracy. The collapse of Terraform in 2022 wiped out an estimated $40 billion from the crypto market. Judge Paul Engelmayer called the fraud "unusually serious," stating that Kwon "publicly lied to the market" for years. Kwon expressed remorse and requested to serve his sentence in South Korea, where he may face additional charges and up to 40 more years in prison. Approximately 16,500 victims were affected, with several testifying about severe financial losses during the sentencing. Kwon is the latest high-profile crypto executive to be convicted, following cases like FTX's Sam Bankman-Fried and Celsius' Alex Mashinsky.

Do Kwon, the co-founder of Terraform Labs, has been sentenced to 15 years in prison after pleading guilty to wire fraud and conspiracy to defraud.

In a Thursday hearing in the US District Court for the Southern District of New York, Judge Paul Engelmayer ordered that Kwon serve 15 years in prison for his role in the collapse of Terraform, which wiped out about $40 billion from the crypto market in 2022.

Prior to making his decision on sentencing, Engelmayer heard from some of Terraform’s victims and questioned what kind of justice Kwon might face in his native South Korea, where authorities are also building a case against him.

“I would like everyone to know that I have spent all my time thinking what I could have done, and what I can do,” said Kwon prior to his sentencing, according to Inner City Press. “It’s been four years since the crash, three years since I’ve seen my family. I’d like to [do] my penance in my home country.”

Engelmayer reportedly said the 12-year recommendation US prosecutors had requested the court impose on Kwon was “unreasonable,” while the five years requested by the co-founder’s lawyers “would be so implausible it would require appellate reversal.”

“To the next Do Kwon, if you commit fraud, you will lose your liberty for a long time as you will here,” said Engelmayer, according to Inner City Press. “You have been bitten by the crypto bug, and I don’t think that’s changed. You must be incapacitated. If not for your guilty plea, my sentence would have been higher.”

The judge added, addressing Kwon:

“Your fraud was unusually serious. For four years you publicly lied to the market [...] The investors were taking a risk, caveat emptor. But they were not taking the risk of being a fraud victim... What makes what you did so despicable is that you traded on trust.”

Kwon could be extradited to South Korea after serving seven and a half years, where he may complete the second half of his US sentence. He could face up to an additional 40 years in prison in his native country.

Several victims have their say during the sentencing hearing

Prosecutors said at the sentencing hearing that there were about 16,500 victims from the collapse of Terraform, according to claims in the company’s ongoing bankruptcy case. Six of them were allowed to address the court via phone before Engelmayer’s decision, describing their financial losses due to Terra.

“I sold my apartment in Moscow to invest with Do Kwon,” said Tatiana Dontsova, one of the victims, according to Inner City Press. “I moved to Tbilisi. $81,000 turned into $13 in the palm of my hand. Kwon came up with Luna 2, calling it LUNC. He is not showing any responsibility for those who invested. I am now officially homeless.”

Kwon, alleged to have had a role in the 2022 collapse of the Terra ecosystem, was handed over to US authorities in December 2024 after his extradition from Montenegro. His legal team delayed proceedings for months by presenting various challenges in the Montenegrin courts.

With Kwon expected to be in prison for years, the Terraform co-founder became the latest former high-profile cryptocurrency executive to enter a plea deal or be found guilty in US courts.

Former FTX CEO Sam Bankman-Fried is serving a 25-year sentence, former Binance CEO Changpeng Zhao served four months — though was later pardoned by US President Donald Trump — and former Celsius CEO Alex Mashinsky was sentenced to 12 years.

Coldcard Theft Reflection: Source Code Visibility Does Not Equal Security

The article examines the open-source vs. closed-source debate in crypto, prompted by a theft of over $100M in Bitcoin from Coldcard hardware wallets. It clarifies key terminology: true "Free and Open Source Software" (FOSS) grants four essential freedoms (use, study, share, modify), while "source available" code, like Coldcard's firmware, may have usage restrictions. The piece argues that visible source code alone does not guarantee security; actual safety depends on the economic incentives for thorough, ongoing review by skilled individuals. Using Bitcoin Core as a model, the article describes a successful, transparent open-source development culture built on public review and consensus. It contrasts this with the Coldcard case, where a critical bug in a lightly-reviewed, source-available library went undetected for years, highlighting a "tragedy of the commons" scenario where assumed but absent scrutiny creates vulnerability. The economics of licensing are crucial: restrictive licenses can limit the pool of motivated commercial reviewers. Finally, the article explores AI's impact. It cites the Bitcoin Red Team's use of AI to rapidly audit codebases and find vulnerabilities at scale, demonstrating a powerful new tool for security. However, AI also floods projects with low-quality code, straining maintainers. The piece concludes that in high-stakes crypto, only well-audited projects—whether open or closed-source—can withstand evolving threats, with AI both challenging and aiding security practices.

Mysterious "Ox Alpha" Large Model Goes Viral with Limited-Time Free Access

A mysterious anonymous AI model named "Ox Alpha," nicknamed "Cow is Coming" by Chinese netizens, has appeared on OpenRouter, sparking widespread speculation. The model offers a 1 million token context, supports text, image, and video inputs, can call tools, and is currently free. Its standout feature is strong coding ability. Initial tests on the DeepSWE benchmark, which evaluates real-world software engineering tasks, showed an 80% pass rate on a subset of tasks, reportedly nearing top-tier code models. However, follow-up tests yielded a 63% score, with variations attributed to different task sets and configurations. The model's true developer is a major topic of debate. The prevailing theory points to Zhipu AI's unreleased GLM-5.3 Flash or its multimodal variant. Evidence cited includes identical visual token consumption patterns with GLM-5V-Turbo for videos, a consistent offset in text token counts compared to GLM-5.3, and similar behavioral traits like refusing audio processing. Zhipu has a precedent of anonymous testing. Simultaneously, another anonymous model, "korrine," appeared on Code Arena, with guesses ranging from Moonshot's Kimi K3.1 to models from Qwen or MiMo, adding to the industry's guessing game. This trend of anonymous "undercover" testing allows for unbiased performance evaluation in platforms like Arena and provides real-world, high-pressure testing through tools like OpenRouter before official release. It also serves as an effective marketing tactic, prolonging discussion through suspense. If Ox Alpha is indeed a "Flash" model, its performance raises expectations for the full-scale version's potential.
