PANews reported on May 3rd that a crypto KOL posted on the X platform questioning the security of a Binance address starting with the number "3," which is listed as the top Bitcoin richest address, holding over 200,000 BTC. The KOL expressed concern that the concentration of large sums of assets in a single address poses a risk of private key collisions and compromise.

In response, Binance founder CZ (Changpeng Zhao) directly stated, "Addresses starting with 3 should be multi-signature addresses, right? To find more than three private keys through a collision? Trust the math." Analysis indicates that Bitcoin addresses starting with 3 are P2SH multi-signature addresses, requiring multiple private keys to authorize transfers, commonly using combinations like "2-of-3" and "3-of-5." Even if theoretically a private key collision is possible, the actual probability of cracking is close to zero, making their security level far higher than single-signature addresses.
