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.

Syvita mining pool
KCV mining pool
KVC mining pool

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.

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 minecitycoins.com.

All an individual party needs to mine CityCoins is a Stacks Wallet and STX tokens. Learn more about where to get STX tokens, and explore STX wallet options.

‍
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?

Read Less
Read More

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.

We're glad to welcome you to the global home of Web3! We're counting on tech and innovation to help drive our city forward.

@rrhoover

“[MiamiCoin’s] interesting because it’s not an involuntary tax, it’s not philanthropy, it’s something that is completely different and could revolutionize the way governments are funded in the future.” – @FrancisSuarez

@PatrickWStanley

Last week @ericadamsfornyc called out that he'd like to have a CityCoin like Miami's.

This week the CityCoins community is delivering for New York City.

@apompliano

This is incredible.

MiamiCoin has now generated over $10 million for the City of Miami, all built on top of bitcoin.

That’s $10 million dollars donated to the city government’s pocket to use on improving the city & quality of life of its citizens.

All from private citizens 👇

@balajis

Citycoins do something interesting: they align residents within cities and encourage economic competition between cities.

This is superior to the pre-pandemic model of political sclerosis within cities and relatively low migration to non-superstar cities.

@Bitboy_Crypto

What's generated $2K every 10 minutes for a city? #MiamiCoin

‍Mayor Francis Suarez "believes that if city-specific cryptos succeed it would mean residents 'won't have to pay a cent in tax'"

This is the future of #Crypto! And we're still early to its adoption! We are inevitable 💪

@Sarasti

#MiamiCoin is not created by the City. @mineCityCoins has enabled a protocol that gifts mining contributions to the City. Separately, we are prioritizing #Bitcoin payment, and yes, this includes exploration of Lightning network. More on this soon.

@rrhoover

CityCoins is a big idea.

Naturally, Miami is first.

@boredelonmusk

This is basically the "Patriot Tax" but executed in a much better way. Which city should @mineCityCoins be deployed in next?

@CuratorBTC

Amazing start for the curator collective, thanks to the #MiamiCoin community, @mineCityCoins @stxnftcom

! The collection "Future of Money", based on work by and in collaboration with Miamian artist Gonzalo Borges, sold out in 10 minutes yesterday.

#MIAMIPOOL IS LIVE 🚨

We’re excited to announce the official launch of #MiamiPool - a smart contract-based trustless system that automates Syvita $MIA mining operations and significantly reduces the risk of pool members losing STX contributions when mining #MiamiCoin.

@APompliano

Wow!

The Miami City Commission just voted in favor of accepting $4.3 million in protocol contributions generated by MiamiCoin, which is built on top of bitcoin.

Today marks a huge day for Miami, and a milestone for crypto.

@rrhoover

Mayor @FrancisSuarez on MiamiCoin’s potential:“We’d be like an oil-producing country, (and) the citizens of Miami could get municipal services without having to pay taxes.”

@balajis

Buy Miami, short SF.

Or, if you believe in the turnaround, go long SF.

Citycoins will express people's faith in city policy. As does emigration. Vote with ballot, and now also with wallet and feet.

@apompliano

I've been spending time with the team and it is fascinating to see something like this secured on top of bitcoin.

The City of Miami already has significant capital that they can access due to the experiment, so would be interesting to see the impact if this continues to work.
