Binance CEO Considers Chain Reorg After Hack
Following the 7,070 bitcoin hack, Binance CEO Changpeng Zhao (or “CZ”) had initially proposed the idea of performing a chain reorg – which could reverse the set of transactions made by the hacker(s). This, CZ had first said, would help recover the funds and serve as “revenge” against the malicious actors.
However, the crypto entrepreneur decided not to attempt a chain reorg after consulting with various experts in the cryptoasset industry.
