Flash Freezing Flash Boys is a novel proposal for per-transaction encryption to prevent frontrunning. Malicious MEV attacks pose a significant threat to traders on Ethereum. Our latest research shows that almost 2,000 sandwich attacks happen daily and more than $2 million is extracted from the network each month. Even traders who execute large WETH, WBTC or stable swaps remain at risk and can lose a substantial portion of their trades. MEV thrives because of the transparent nature of blockchains, where transaction data is visible before transactions are executed and finalized. One path toward mitigating MEV is mempool encryption, particularly through the use of threshold encryption. In our earlier articles, we examined two different models for threshold-encrypted mempools. Shutter, one of the first projects to apply threshold encryption to protect the mempool, introduced a per-epoch setup. Batched threshold encryption (BTE), a newer model, decrypts multiple transactions with a single key to reduce communicat...
Analysts are split on whether the drop represents a cycle low or a pause before further downside. Bitcoin’s sharp correction at the start of the month may represent a critical “halfway point” in the current bear market, according to Kaiko Research. Bitcoin (BTC) fell to $59,930 on Friday, marking its lowest level since October 2024, before the re-election of US President Donald Trump, according to TradingView data. The decline suggests the market has moved out of the euphoric post-halving phase and into what Kaiko described as a historically typical bear market period that lasts about 12 months before a new accumulation phase begins.

Phantom Chat is under scrutiny after a phishing attack drained $264,000 in Wrapped Bitcoin, renewing concerns over wallet UX and address poisoning scams. A built-in messaging feature in the Phantom crypto wallet is drawing scrutiny from security researchers after an investor lost about $264,000 worth of Wrapped Bitcoin in what investigators described as a phishing attack enabled by address poisoning. Blockchain investigator ZachXBT shared blockchain data pointing to a victim losing 3.5 Wrapped Bitcoin (wBTC) in a suspected phishing attack tied to Phantom Chat. The data shows a transaction where 3.5 WBTC was transferred from address 0x85c to address 0x4b7 on Wednesday, flagged as a “high balance” address on blockchain intelligence platform Nansen. The transaction pattern is consistent with address poisoning, a phishing technique that exploits users’ transaction histories rather than compromising private keys. Read more
The UK’s financial watchdog sued Panama-based HTX exchange and unidentified persons, alleging illegal crypto promotions on social media despite warnings. The United Kingdom’s financial watchdog has launched court action against cryptocurrency exchange HTX, alleging it illegally promoted crypto asset services to British consumers in breach of financial advertising rules.
