Crypto security efforts across Ethereum are getting a fresh boost as scams continue to drain funds from everyday users. In response, the Ethereum Foundation has launched a new partnership aimed at reducing losses and improving real-time visibility into emerging threats across the ecosystem.

Crypto market on alert: Phantom faces controversy after a $264,000 theft. We give you all the details in this article.

The announcement shook the crypto ecosystem this Friday. The Ethereum Foundation officially announced the creation of a dedicated post-quantum security team, backed by $2 million in funding. This decision marks a strategic turning point for the world's second-largest blockchain, elevating quantum resistance to an absolute priority.

The EU has found TikTok’s features addictive and is calling for platform reforms, with potential fines if changes are not made.

The debate over online age verification intensified this week after Telegram co-founder Pavel Durov criticized Spain’s proposal to restrict social media access for users under 16. Spanish officials say the measure is designed to protect children online, but critics argue it could expand government surveillance and erode digital privacy. The plan has drawn particular concern from the public, who warn of broader consequences for anonymous communication online.

Vitalik Buterin turns a page in Ethereum's history. In a published post, the protocol's cofounder calls into question the strategic vision of Layer 2, long considered the key to the network's scalability. For him, the rollup-centric model no longer delivers on its promises. As Ethereum continues its transformation, Buterin calls for a profound rethinking of the role of second-layer solutions. This stance could well redefine the future of the ecosystem.

In a network where every line of code can become a manifesto, the slightest technical signal takes on the appearance of a political declaration. BIP 110, supported by a growing fraction of Bitcoin nodes, illustrates this internal tension. Behind this seemingly minor proposal lies a clear intention: to tighten control over data insertion into the blockchain and defend a stricter vision of the protocol.

While quantum computers sharpen their circuits, Ethereum brings out the heavy artillery: cryptographers, millions, and devnets. The blockchain wants to last a hundred years, even if it ages before us.

The security of crypto data falters once again. The French platform Waltio, specializing in tax declarations, was the victim of a massive leak of sensitive information. In response, an investigation was opened by the French authorities, mobilizing the National Gendarmerie. This incident rekindles concerns about the vulnerability of services related to cryptos, including those outside the blockchain. As the use of tax tools becomes widespread, users' trust is severely tested.

At the Devconnect conference in Buenos Aires, Ethereum's co-founder issued an unprecedented warning: the elliptic curves securing Bitcoin and Ethereum 'are going to die.' With a 20% probability that quantum computers could break current cryptography before 2030, the crypto industry has less than four years to migrate to quantum-resistant systems.

Saga, a Layer-1 blockchain protocol, has paused its Ethereum-compatible SagaEVM chainlet after a $7 million exploit triggered unauthorized fund transfers. The attack involved assets being bridged out of the network and swapped into Ether. Although the affected chainlet remains offline, Saga says the broader network continues to operate normally.

In the world of cryptocurrencies, hacks have become events that are both frequent and dramatic. The main data is clear: nearly 80% of hacked crypto projects never fully recover, even after fixing their technical vulnerabilities. This means that most protocols experiencing a major attack remain permanently weakened — financially and in terms of trust.

An explosive case shakes the crypto market: three Polymarket whales targeted for suspicious bets on Venezuela. Details here!

Two major cybersecurity incidents shook user confidence in late 2024: $7 million stolen via a compromised Chrome extension at Trust Wallet, and another personal data leak at Ledger.

Reports of a potential large-scale Instagram data leak have sparked widespread concern, as cybersecurity researchers and Meta offer sharply different accounts of what occurred. While a security firm claims millions of user records are being sold online, Meta insists its systems were not breached. The conflicting narratives have left many users uncertain about the safety of their accounts.

A crypto user known as “The Smart Ape” lost about $5,000 from a hot wallet during a short hotel stay. No phishing links were opened, and no fake sites were used. Instead, a chain of small missteps created the conditions for a delayed wallet drain. Security researchers say the case shows how everyday actions, both online and offline, can combine into a serious loss.

Ledger users are being targeted by a new phishing campaign following a data breach at Global-e, a third-party e-commerce provider used by the hardware wallet company. Attackers are using stolen order information to send personalized scam emails that impersonate Ledger and promote false claims of a merger with rival wallet maker Trezor.

Crypto phishing losses dropped 83% in 2025, with fewer victims and smaller attacks, yet new wallet scams and evolving threats continue to challenge users.

Ilya Lichtenstein, involved in the theft of approximately 119,756 BTC on Bitfinex, says he was released from prison earlier than expected thanks to the First Step Act, a law passed under Donald Trump. He spent just over a year behind bars, although he had been sentenced to five years.
