The blockchain network Horizen that supports zero-knowledge will undergo a network upgrade on the mainnet through a hard fork at block #1502800 on February 7th at 8:00 PM Beijing time with the release of ZEN 5.0.0.After the hard fork, users will no longer be able to perform any transactions involving shielded addresses. The official recommendation is to move funds out of the shielded pool before this time and not to deposit funds directly from shielded addresses into exchange wallets.Previously, Horizen released a tweet stating that they have communicated with Binance and OKEx to ensure that ZEN is no longer a privacy token. They plan to completely remove the shielded pool on the Horizen main chain, including disabling the shielded transaction function, removing related RPC calls, and providing users with a migration path to move assets out of the shielded pool before the ZEND 4.2.0 hard fork in mid-February.
