MiamiCoin is the first ever city coin, but what does it do?
It's just two months since the city hosted
Bitcoin Miami and promised to become the Bitcoin (BTC) capital of the world. Now, Miami has snatched the crypto headlines once again as it launches its own digital currency, MiamiCoin (MIA).
Miami will be the first city to have its own coin, which is being created in partnership with a company called CityCoins. Let's look at how the coin works and see whether (and how) it could benefit the city and investors.
How does it work?
CityCoins has built MiamiCoin using a programmable blockchain called Stacks (STX). Starting August 3, people can mine MIA, a process that generates new coins and supports the network.
The idea is that individuals can use STX to mine MiamiCoin, and 30% of the revenue will go to Miami. The city can use that cash to fund any projects it wishes, including, according to Mayor Francis Suarez, helping the homeless or funding policing initiatives.
MIA owners can lock in the remaining 70% of the money to earn rewards in Stacks and Bitcoin. It is unusual to be able to earn Bitcoin rewards in this way. However, the process of mining, buying MIA, and earning rewards is not entirely clear.
Can you spend it?
You'll never be able to spend MiamiCoin as a currency in the city. Federal law prohibits cities from creating their own currencies. So the U.S. dollar is the only currency you could ever spend in Miami.
According to CityCoins, the coins will become more useful with time. It says on its website, "CityCoins communities will create apps that use tokens for rewards, local benefits, access control (to digital or physical spaces), trading, lending, smart contract execution, and more." For example, coins might be used to gain discounts at local businesses.
What is Stacks?
Stacks is an interesting project because it sits on the Bitcoin platform and has
smart contract capabilities. It's a layer-2 solution, so it operates on top of the existing blockchain. Smart contracts are small pieces of code that make a blockchain database programmable. One of the downsides of the Bitcoin ledger is that it can't store smart contracts, so if the Stacks technology works, it could add a great deal of utility to Bitcoin.
Stacks also says its language (Clarity) is special because it is coded in a language that people can actually read. Plus, investors can earn both BTC and STX by "stacking" their coins. This is the same mechanism that would pay MIA token holders.
Stacks originally erred towards regulatory caution, which backfired somewhat. In 2019, when it launched the STX token, it was the first ever token to be SEC qualified. That SEC approval meant STX was treated as a security that could only be bought and sold with registered stock brokers. Unfortunately, it couldn't be traded on
U.S. cryptocurrency exchanges.
This January, Stacks announced it had completed the process to become a
cryptocurrency and that U.S. exchanges
could now trade STX. So far, only Okcoin has listed it."
