How to mine CityCoins

To mine CityCoins, you need a Stacks Wallet and STX tokens.
Once you have those, there are two ways to mine:

Join a mining pool

Recommended for most people. Mining pools automate the process and reduce individual risk.

Mine independently

Recommended for people who want to mine with a larger amount of STX.

How it works

CityCoins are powered by Stacks, a protocol that enables smart contracts on the Bitcoin network.

STEP 1

The community mines to create CityCoins

Mining CityCoins is performed by forwarding STX tokens into the smart contract in a given Stacks block, and is a one-way process. Miners are rewarded with new CityCoins tokens.

STEP 2

Stackers receive the STX spent to mine the CityCoins

70% of mining rewards are distributed to people who chose to stack their CityCoins (Stackers).

STEP 3

The city's reserved wallet grows

30% of mining rewards are sent (in STX) to a city's custodied reserve wallet.

The city can claim this and convert their STX to USD whenever they want.

What is a mining pool?

Individual miners can pool their funds together and mine CityCoins as a team.
There are two main options for mining pools:

- Custodial: an administrator for the pool will manage funds, make contract calls, and issue payouts to pool members
- Non-custodial: powered by smart contracts, miners can participate simply by sending a transaction and the contract manages the mining and payouts

The Syvita Guild started the first custodial mining pool for MiamiCoin, and has since deployed a non-custodial version at syvitamining.com targeting all current and future CityCoins.

Community-run mining pools like Syvita’s have proven popular with CityCoins miners, and provide fully democratized access to CityCoins mining across many blocks, helping significantly reduce individual miners’ risk.
