Overall, Zcash tokenomics is similar to that of Bitcoin: it is a scarce [mineable] token with a total supply limit of 21 million coins.
New ZECs are created in the form of “block subsidies”: whenever [a new block is mined] and added to the end of the blockchain, a certain amount of coins is minted and split into “miner subsidy” and “founders’ reward” at a ratio of 80 to 20 percent respectively. The block subsidy is halved at regular intervals to slow down the issuance rate as the total supply of ZEC approaches its limit of 21 million.
The miner subsidy goes to the miner who has mined the latest block and the founders’ reward is distributed between Electronic Coin Company (ECC) founders, Zcash Foundation and ECC itself, as well as its employees. On Nov. 18, 2020, the block subsidy was halved from 6.25 ZEC to 3.125 ZEC, which was triggered at block 1,046,400. This was introduced under the [Zcash Canopy] upgrade, which also removed the Founders Reward. Instead, the remaining 20% will be divided among the Major Grants Fund, ECC and Zcash Foundation, at 8%, 7% and 5% respectively. The next, and fifth, [Zcash network upgrade] — [Zcash NU5] — is estimated to go live on the testnet on Sept. 30, 2021.
Since launch there has been substantial interest in the [ZEC to AUD] and [ZEC to EUR] price pairs.
