Malikie Innovations, which acquired over 32,000 patents from BlackBerry in 2023, has filed lawsuits against major Bitcoin mining firms Marathon Digital and Core Scientific. At the heart of the dispute lies elliptic curve cryptography (ECC), a core component of Bitcoin’s blockchain protocol.

Cryptography Under Scrutiny

According to Malikie, the ECC techniques used by Bitcoin are protected under patents they now hold. Their lawsuit claims that these mining companies have been infringing on their intellectual property by supporting Bitcoin operations with ECC-based methods.

What’s more, Malikie seeks damages for up to six years of retroactive royalties. If awarded, the damages could be significant—possibly severe enough to force companies like Core Scientific into financial distress.

Could The Entire Network Be at Risk?

Experts suggest that a victory for Malikie might set a dangerous precedent. Other miners in the US could become targets, and the case could raise concerns over the legal stability of Bitcoin’s cryptographic foundation.

However, industry analysts like Niko Demchuk from AMLBot believe Malikie’s claims may not hold up. He suggests the patents in question may be expired or cover techniques predating Bitcoin’s implementation of ECC.

This is not the first intellectual property challenge in the crypto world. In the past, figures like Craig Wright have made failed attempts to claim ownership of Bitcoin’s underlying technologies. But this case serves as a reminder: even decentralized networks aren’t immune to centralized legal disputes.

Increasing Security Concerns for Bitcoin Holders 

With the growing adoption of BTC, long-term investors have started to attract attention. Early Bitcoin holders, known as “OG,” are becoming potential targets. Jesse Posner, co-founder of Vora, stated that long-term investors could face serious security threats. 

“Extreme bitcoinization will make those holding crypto for a long time the most attractive targets in the world,” Posner explained. 

Malmi proposed an organization named “Bitcoin Mossad” to ensure the security of OG investors and take precautions against potential threats. He suggested that such an organization might be appropriate in countries like El Salvador, where BTC is recognized as legal tender. 

Maybe we need a "never forget, never forgive" type organization as a deterrent. Bitcoin Mossad hosted by El Salvador?

However, OG investors face high risks due to their assets, making them targets of cyber attacks, fraud attempts, and even physical threats. As Bitcoin’s popularity and value increase, so does the likelihood of these individuals becoming targets. Therefore, protecting OG investors is critical for the healthy growth of the crypto ecosystem. 

Responsibility of Security Companies and Marketing Strategies 

Alex Stanczyk, CEO of Swan BTC, emphasized that security companies should be cautious with their marketing strategies. Stanczyk noted that offering unrealistic security promises can be misleading and lead to greater risks. Transparency and realism in marketing security solutions are crucial. 

With BTC‘s global adoption increasing, investor security has become more important than ever. The “Bitcoin Mossad” proposal highlights the need for new strategies to address security vulnerabilities and protect OG investors. In the crypto world, OG refers to early entrants and respected pioneer investors. Increasing security measures and raising awareness among investors will be critical for the sector’s sustainability in the future.

The post Critical Security Recommendation for Bitcoin: Here Are the Details  appeared first on Coin Engineer.

Addressing Past Issues and Enhancing Transparency

“The project has historically done a poor job at publicly disclosing security-critical bugs, whether externally reported or found by contributors” Bitcoin Core developer Antoine Poinsot and five others wrote to members of the Bitcoin Development Mailing List on July 3. This has led to a situation where Bitcoin users are led to believe that Bitcoin Core is free of bugs, but Poinsot stressed that this simply isn’t the case. “This perception is dangerous and, unfortunately, not accurate.”

Bitcoin Core is the software that Bitcoin node operators download to access the Bitcoin blockchain, validate transactions, and build blocks. It plays a crucial role in securing more than $1.1 trillion locked in the Bitcoin network. Poinsot said the new policy would allow better communication about the risk of running outdated versions of Bitcoin Core and would provide a standardized disclosure process that would give researchers more incentive to find and responsibly disclose vulnerabilities. “Making the security bugs available to the wider group of contributors can help prevent future ones.”

Categorizing Vulnerabilities and Disclosure Timeline

The new disclosure policy will categorize vulnerabilities based on four levels of severity. The categories include:

1. Low: Bugs that are hard to exploit and have low impact, such as a wallet bug that requires access to the victim’s machine.
2. Medium: Bugs with limited impact, such as local network remote crashes.
3. High: Bugs that could have significant impact.
4. Critical: Bugs that threaten the entire network’s integrity, such as manipulating Bitcoin Core to inflate Bitcoin’s hard-capped supply or committing a “coin theft.”

Low, medium, and high bugs will aim to be disclosed two weeks after a fixed version is released, while disclosures for critical bugs will be determined on a case-by-case basis. The policy will be “gradually adopted” in the coming months, Poinsot added.

Poinsot noted that all vulnerabilities fixed in Bitcoin Core versions 0.21.0 and earlier have been disclosed as of July 3, and disclosures for versions 0.22.0 and 0.23.0 will come out later this month and in August. Bitcoin Core version 27.1 is the latest version adopted.

The new policy received praise from fellow Bitcoin Core developer Eric Voskuil: “Many other projects have been on the receiving end of this misperception, and it has in fact caused material harm to the community. I don’t know what precipitated this change, but props to you all for stepping up.”
