Token Configuration
An overview of the token component of the CityCoins protocol.


CityCoins are fungible tokens on the Stacks blockchain with no ICO, no pre-sale, and no pre-mine.
Once a CityCoin is deployed and activated, the issuance schedule begins and winning miners mint the CityCoin into existence.
CityCoins can be sent and received using a STX address, used for payment in smart contracts, and more.
For a more technical explanation, please see the contract functions for CityCoins tokens.

Issuance Schedule

Miners receive coinbase rewards for mining CityCoins outlined in the table on this page per block.
The issuance schedule does not begin until mining is activated, and once it begins, the current block height of the Stacks blockchain is recorded in the smart contract.
From there, the amount of CityCoins rewarded through mining follow a similar issuance schedule to that of Bitcoin and Stacks, where the mining rewards are cut in half over the next 20 years.
There is a bonus block reward for early miners who participate in the first 10,000 blocks.
