🍿 A quantum computer for the first time demonstrated a real attack on elliptic curve cryptography — a researcher recovered a 15-bit key and received 1 BTC from Project Eleven for it.

The threat to Bitcoin is still very far off — BTC uses 256-bit keys, and cracking them requires orders of magnitude more power than current capabilities.

But the fact itself is important: the quantum threat to blockchains increasingly looks not like science fiction, but a matter of time and engineering progress.

🇪🇺 The ECB has chosen payment standards for the digital euro and will build the infrastructure on existing open technologies ECPC, nexo standards and Berlin Group.

The idea is to reduce implementation costs for banks and businesses, accelerate the launch of CBDC, and reduce Europe's dependence on Visa, Mastercard, and global digital wallets.

The first issue of the digital euro is still tentatively expected in 2029.

🪙 Bitcoin network activity has fallen to 2018 bear market levels, although the price has grown many times since then.

Analysts believe this may indicate a shift in demand towards institutional players — Bitcoin is increasingly being used through centralized services, rather than directly on-chain.

🔫 Trump was shot at again — at the White House Correspondents' Dinner at the Washington Hilton, a man with several weapons attempted to breach a security checkpoint, gunfire ensued, one agent was hit in the bulletproof vest, and Trump, Melania, and Vance were urgently evacuated.

The suspect was apprehended, the motive has not yet been disclosed, but the story has already become a political shock — especially given that this is the very hotel where Reagan was shot in 1981.

Crypto also quickly entered the narrative: a version spread on social media that the suspect had MetaMask with TRUMP and MELANIA, but there is no official confirmation of this yet.

🪙 A reorganization of 13 blocks occurred in the Litecoin network after a zero-day vulnerability attack — attackers disrupted the operation of large mining pools and attempted to conduct invalid transactions via MimbleWimble Extension Block.

The developers rolled back the blockchain — the attack lasted over three hours and affected several cross-chain protocols.

⚖️ In the US, 22-year-old Evan Tangeman was sentenced to 70 months in prison for participating in a crypto fraud scheme worth $263,000,000.

The stolen money was laundered through a complex network and spent on a luxurious life — expensive mansions, Lamborghinis, Rolexes, and other attributes of "successful success".

🚬 Not a day without a hack — today Scallop, one of the leading DeFi protocols on Sui, was hacked.

The exploit affected the sSUI reward pool side-contract, from which approximately 150,000 SUI were stolen, but the main contracts and other pools remained secure.

Scallop has already frozen the affected contract and promised to compensate 100% of losses at its own expense.

💸 DeFi United has already raised over 100,000 ETH ($234 million) for Aave's recovery after the Kelp hack — this almost covers the $290 million damage.

Mantle contributed the most — 30,000 ETH, and DAO Aave — 25,000 ETH; another approximately 30,700 ETH was returned by freezing stolen funds in Arbitrum.

🔐 How long does it take to crack a password? Everything is decided by length and variety of characters: 8 characters consisting of letters, numbers, and symbols can be brute-forced in about 5 months, while 12 characters with the same set — already up to 10 million years.

A normal long password with numbers, letters, and symbols is practically impossible to guess by brute force, while short and simple combinations, such as qwerty123, are cracked almost instantly.

🤣 On Polymarket, only 3% of traders actually set prices and take the lion's share of profits — the remaining participants mostly lose money, effectively "funding" this small group.
