Here’s what happened in crypto today

Today in crypto, as the market bloodbath continues, one Ethereum whale was forced to make an emergency $14 million Ether deposit to avoid the potential liquidation of a short position worth around $340 million, Bitcoin hashrate trackers show the network crossed over 1 zetahash per second, and cypherpunk Jameson Lopp has sounded the alarm on Bitcoin address poisoning attacks.Whale makes $14 million Ether emergency deposit to avoid $340 million liquidationAn unidentified cryptocurrency whale injected millions of dollars in emergency capital to avoid a potential liquidation of more than $300 million in Ether as markets slumped amid renewed macroeconomic pressure.The whale is reportedly close to liquidation on a 220,000 Ether (ETH) position on MakerDAO, a decentralized finance (DeFi) lending platform. To stave off liquidation, the investor deposited 10,000 ETH — worth more than $14.5 million — and 3.54 million Dai (DAI) to raise the position’s liquidation price, blockchain analytics firm Lookonchain said in an April 7 post on X.“If $ETH drops to $1,119.3, the 220,000 $ETH($340M) will be liquidated.”The development came hours after another Ether investor was liquidated for over $106 million on the decentralized finance (DeFi) lending platform Sky.The whale lost more than 67,000 ETH when the asset crashed by around 14% on April 6. Sky’s system employs an overcollateralization ratio, typically 150% or higher, meaning that users need to deposit at least $150 worth of ETH to borrow 100 DAI.Bitcoin hashrate tops 1 zetahash in historic firstThe Bitcoin network hashrate has topped 1 zetahash per second (ZH/s) for the first time in Bitcoin’s 16-year history, according to several blockchain data sources.Bitcoin’s hashrate crossed the milestone on April 5 at a peak of 1.025 ZH/s, according to mempool.space data, while BTC Frame data said it hit 1.02 ZH/s a day earlier.Data from Coinwarz says that Bitcoin hashrate soared to as high as 1.1 ZH/s on April 4 at block height 890,915 — however, the same data indicates that Bitcoin first crossed 1 ZH/s on March 24.The Bitcoin network’s reported rise to 1 ZH/s — equivalent to 1,000 Exahashes per second — marks a 1,000x increase since late January 2016, when Bitcoin first hit 1 EH/s for the first time. Cypherpunk Jameson Lopp issues warning on Bitcoin address poisoningCypherpunk and crypto executive Jameson Lopp sounded the alarm on Bitcoin (BTC) address poisoning, a social engineering scam that uses addresses similar to those found in a victim's transaction history to fool them into sending funds to the scam destination.This is done through brute force creation of addresses that match the first and last four digits of addresses displayed in the victim's transaction history.The malicious actors then send the victim a small amount of Bitcoin, typically under $1, so that the malicious address will also now appear in the victim's transaction history.Lopp urged better wallet user interfaces that fully display addresses and urged Bitcoin holders to always exercise caution, thoroughly reading and verifying destination addresses instead of simply copying and pasting from a transaction history list.
