[ANN][CITY] City Chain - Blockchain for the Smart City Platform

Recommended Posts


City Chain is the blockchain that powers the Smart City Platform. A decentralized platform empowering global citizens in the modern era. City Coin (CITY) is the means of value exchange, yet the Smart City Platform will be supporting multiple crypto-currencies (including Bitcoin) as a means for payments and other operations.




Our goal is to make crypto-currencies and crypto-services available to, and used by, everyone.

When additional support for CITY (City Coin) is added by other apps and services, they will be listed on this announcement in an update.




City Chain is built on the Stratis Blockchain Platform. It will continue to adopt the majority, if not all, future improvements and modifications made to the Stratis Blockchain Platform. City Chain, and the Smart City Platform, will build on the foundations of this platform and extend it with additional functionaly and features that goes above and beyond.

By relying on the existing platform, we get the benefit of an active development community around Stratis, and we gain a large test-base for new technology and abilities, such as Smart Contracts and sidechains.

Liberstad Block Exchange

Liberstad is a new city under development in Norway and is an important partner and sponsor of City Chain. Liberstad will be one of the first cities to utilize the City Chain and Smart City Platform. 


More partners to be announced in the future.


The goal of City Chain is not to be a competing currency to other cryptocurrencies, but to be an enabler for utilizing blockchain technology and cryptocurrencies at a broader and wider scale than exists today. It is not only about (new) private cities, the Smart City Platform can be utilized by existing cities and communities to reduce costs and improve efficiency in some of the services provided to the citizens.
