Here’s what happened in crypto today
Today in crypto, Bitcoin hashrate trackers show the network crossed over 1 Zetahash per second, cypherpunk Jameson Lopp has sounded the alarm on Bitcoin address poisoning attacks, and a recent court filing shows nearly 400,000 FTX users risk losing $2.5 billion in crypto repayments unless they complete Know Your Customer (KYC) verification before the extended June 1 deadline.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 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.Nearly 400,000 FTX users risk losing $2.5 billion in repaymentsNearly 400,000 creditors of the bankrupt cryptocurrency exchange FTX risk missing out on $2.5 billion in repayments after failing to begin the mandatory Know Your Customer (KYC) verification process.Roughly 392,000 FTX creditors have failed to complete or at least take the first steps of the mandatory Know Your Customer verification, according to an April 2 court filing in the US Bankruptcy Court for the District of Delaware.FTX users originally had until March 3 to begin the verification process to collect their claims.“If a holder of a claim listed on Schedule 1 attached thereto did not commence the KYC submission process with respect to such claim on or prior to March 3, 2025, at 4:00 pm (ET) (the “KYC Commencing Deadline”), 2 such claim shall be disallowed and expunged in its entirety,” the filing states.The KYC deadline has been extended to June 1, 2025, giving users another chance to verify their identity and claim eligibility. Those who fail to meet the new deadline may have their claims permanently disqualified.
