The privacy coin project Zcash (ZEC) is expected to usher in the “Heartwood” network upgrade at around 18:30 on July 16. Lianwen previously reported that Zcash will activate Heartwood at block height 903000. Heartwood network upgrade will deploy ZIP 213, ZIP 221. Among them, ZIP 213 allows miners to directly send their mined block reward tokens to shielded addresses, and ZIP 221 enables Flyclient support by changing the semantics of the existing block header field. At the end of May, Zcash Development Company Electric Coin Company (ECC) launched version 3.0.0, which supports the activation of Heartwood on the mainnet.
