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.


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.


Stackers receive the STX spent to mine the CityCoins

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


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.

Anyone can mine CityCoins by submitting a transaction to a CityCoins smart contract on the Stacks blockchain.

There are no hardware requirements and the protocol is open source, so anyone can build a website that interacts with it. The main website for mining/stacking CityCoins is

CityCoin miners spend STX while competing to earn CityCoin block rewards, which is defined by the token emissions schedule and begins at 250,000 CityCoins per block.

There is only one winning miner per block that can claim the CityCoin reward.

All STX submitted to mining are distributed:
- 30% to a reserved wallet for the city
- 70% to CityCoin holders who have stacked tokens (Stackers)

To learn more about how the mining process works, how to mine, mining strategy, and how to claim rewards, read the mining documentation.

The city can claim their reserved wallet and convert their STX to USD whenever they want. They can also stack the STX to earn BTC.

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 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.
