πŸ—ƒA quantum computer has demonstrated a real attack on elliptic curve cryptography for the first time

The researcher recovered a 15-bit key and received 1 BTC from Project Eleven.

It's too early to talk about a threat to Bitcoin, as BTC uses 256-bit keys, and cracking them requires computational power orders of magnitude greater than current capabilities.

But the fact remains: a quantum threat to blockchains increasingly appears less like science fiction and more like a matter of time and engineering progress.

On-chain analyst Woominkyu predicts a possible Bitcoin correction to $74,000–75,000

On April 27, net inflows to exchanges totaled 9,905 BTC, a 30-day high. During this period, Bitcoin failed to consolidate above $78,000. Transactions from the top 10 largest players accounted for more than 70% of all deposits. The analyst estimates that whales are transferring assets to exchanges to sell.

Exchange reserves increased from 2.666 million BTC to 2.677 million BTC from April 25 to 28. If buyers fail to absorb the supply, Bitcoin will test the $74,000–75,000 support.

a16z crypto tested whether AI agents can independently carry out attacks on DeFi

Without prompts, only 10% of attempts were successful, while with a knowledge base of past hacks, the success rate was up to 70%.

The AI ​​almost always found vulnerabilities, but it "broke" at a key stageβ€”building a working exploit. It made calculation errors, struggled with multi-step schemes, and sometimes abandoned its working idea.

In other words, AI is already helping to find bugs, but complex DeFi hacks remain a human task.

Strategy has accepted the sale of Bitcoin to pay dividends on STRC preferred shares

The company previously publicly maintained a stance of "never selling" Bitcoin.

Strategy founder Michael Saylor noted that, with Bitcoin growing at 2.3% annually, existing reserves would be sufficient to cover the dividend without selling common shares. CEO Phong Le added that the company's priority is to increase Bitcoin per share.
