How to get MiamiCoin?

How it works

MiamiCoin is powered by Stacks, a protocol that enables smart contracts on the Bitcoin network. Anyone can compete to mine MiamiCoin by forwarding their STX tokens through the protocol.

30% of miners’ forwarded STX is directed towards a wallet reserved for Miami, and the remaining 70% can be stacked to yield STX and BTC.

Mining CityCoins

CityCoins are mined by forwarding STX into a CityCoins smart contract on the Stacks protocol. The winner of each block reward is selected randomly, weighted by total STX spent. CityCoins are claimed by the winning miner and can then be stacked to yield returns in STX and BTC.

Stacking CityCoins

CityCoins can be locked on the Stacks protocol for a voluntary period of time, yielding STX as a reward. The rewarded STX comes from the 70% of forwarded STX from CityCoin miners. The yielded STX can be further stacked to yield BTC.

The city of Miami has not partnered with CityCoins. CityCoins are grassroots initiatives. As communities grow around CityCoins, they can encourage their mayor to claim the reserved city treasury wallet and begin putting its funds to use.

30% of the STX that miners forward in order to compete in the earning of MiamiCoin will go directly to the wallet reserved for the city. The city of Miami may decide at any time to claim the wallet’s funds.

The MiamiCoin treasury consists of STX, which is sent by miners when they forward the funds to a Stacks smart contract for the right to compete in a mining competition. 30% of the STX forwarded by miners makes its way into the city treasury. Whenever the city wishes, they may access their reserved STX inside the wallet. At that point, Miami may use its treasury for whatever it deems fit and compliant.

With MiamiCoin, you can mine it, hold it, stack it to earn STX and BTC yield, borrow it, lend it, and program it. Built on open source software, MiamiCoin is a new way for developers to create applications and experiment with innovative use cases.

At launch, the benefit of MiamiCoin will be generating STX and BTC yield. However, MiamiCoin is programmable and will have additional utility over time. Developers will create apps that use MiamiCoin for access control (to digital or physical spaces), trading, lending, smart contract execution, and more.
