Privacy-focused Zcash (ZEC) is approaching its first halving on November 18th, shortly before 1 pm UTC, as the block rewards will drop from 6.25 to 3.125. Zcash has been under heavy scrutiny recently, as a member of the privacy coin family. ShapeShift, the Colorado-based cryptocurrency exchange founded by Erik Voorhees, delisted Zcash (ZEZ), Monero (XMR) and Dash (DASH) this month due to regulatory concerns. Last week, South Korea’s Financial Services Commission (FSC) unveiled new Anti-Money Laundering (AML) regulations, including a blanket ban on privacy coins, in response to the disturbing Nth Room case involving the sexual exploitation of underage girls. In the United States, the Internal Revenue Service (IRS) has offered $625,000 for new tools to crack bitcoin mixers and privacy coins like Zcash. Unlike Bitcoin that makes all transactions and wallet balances public, Zcash does not have a public blockchain, making it impossible for blockchain analytics firms like Chainalysis or Elliptic to track. Block halving event happens every 4 years on the Zcash blockchain. The initial block reward was 12.5 ZEC, and the new block reward will be 3.125 ZEC. The block reward splits every 4 years (840,000 mined blocks). The halving is programmed directly into Zcash's codebase by its foundation. Development work on Zcash began in 2013 by Johns Hopkins cryptography professor Matthew Green and some of his graduate students (read their blog). Similar to gold, which has limited supply and cannot be printed or artificially created, the total supply of Zcash will be maxed out at 21,000,000 ZEC. The halving event will effectively reduce its inflation rate from 25% to 12.5%. Learn more about the Zcash halving at Nicehash.
