Smart City Platform will host a number of software and services, that makes the crypto-currencies
and blockchain-technologies available to everyone.
This is your entrance hub into the Smart City Platform. All software and services mentioned below, will be integrated
into the portal.
City Hub will be accessible from any device, including iOS, Android, and desktop computers through the City Portal
app and website.
City Chain blockchain
This is what will power the Smart City Platform, a new Proof-of-Stake (PoS) crypto-currency by the name City Coin. While
the Smart City Platform is being built to integrate and run on multiple blockchains, this new blockchain
will the be first and primary blockchain utilized by the Smart City Platform.
New City Coins are produced through staking (PoS), which is something anyone who owns CITY can participate in.
Secure Messaging & Community
Already under development, is a secure community app being built to allow anyone to contribute to communities in a secure,
and private manner. If a user wants to stay entirely anonymous, that is possible. The app runs without any
major infrastructure, no installations or servers required. All data is stored in the web browser and is
never sent unencrypted over the network.
For free, anyone can create their own secure communities which has zero centralized storage. A paid service will be available
for secure and encrypted centralized storage of communities, making content syncronization faster and secure
backup of content.
It is a fairly known fact that blockchain technology and crypto-currencies still are only accessible to individuals with
basic technical skills. It is essential that crypto-currencies are made accessible and available to everyone,
without any technical skills. A user with a smart phone, should easily be able to pickup the wallet-app and
start transfering funds into their account, and payment for goods in stores should be instant and seamless.
Being able to perform transactions using NFC will be an important aspect of the wallet app for the City Coin, allowing users
to quickly perform small-sum transactions without any confirmation other than physical access to a phone.
The limits for NFC payments is controlled entirely by you, the user.
The City Coin is a Proof-of-Stake (PoS) crypto-coin, and a full-node desktop software will be available for Windows, Mac
and Linux. The City Chain Foundation will be hosting a number of full-nodes to ensure network stability and
While we will have our own wallet app to ensure great user experience, we are working with others to ensure that City Coin
is widely adopted and supported by other wallet software.
City Hub supports different usage modes, and from launch will support both mobile and desktop.
Mobile - Mobile optimized, released to appstores on Android and iOS.
Light - Light node UI that does not require download of full blockchain.
Full - Full node UI that support staking, and does a complete verification of the blockchain.
Point-of-Sale (POS) - Merchant UI that is optimized for touch screen usage.
Read-only - A more secure mode that allows you to see all your data, without using your
You are the source of your identities, and how and what you identity as, is up to you. If you want to change your name that
you are using for trades and interactions with anyone, that is available to you. You can choose to have a
single identity, or multiple.
As you interact with others through the Smart City Platform, your identities will build up trust. Similar to how trust is
important in a human society today, it will be even more important in the digital space going forward.
City Chain is planning to support the
Decentralized Identifiers (DIDs) specification, including implementation of Universal Resolver, Universal
Registrar and Identity Hubs. By implementing these open specifications, you can potentially use your identity
on the City Chain, to authenticate across multiple desentralized blockchains and systems.
As you know already, having a user friendly and easy to use list of contact is very valuable in your daily life.
On the Smart City Platform, your contacts will be stored encrypted and securely. They can be connected to
identities that exists on the platform, enabling frictionless payments between you, and all your contacts.
Simply search for an individual, and make a crypto-currency payment in seconds.
The merchant framework on the platform is a very important piece of the whole. The platform will enable existing merchants
to improve their sales and customer experiences, but the platform will also enable just about anyone, to
become a merchant that sells goods and services, both online and offline in the world.
Stability is often important for a merchant, so the framework will support the ability to receive payment in the currency
of choice by the merchant. If you want to have a local fiat currency, you can do so. If you want a mix of
currencies, that is possible too.
Integrations with existing webshop frameworks will be added, allowing merchants to easily integrate into the Smart City Platform,
while continue to use existing software for online trading.
Merchant registry will be part of the merchant framework, and allow citizens to discover the merchants that are
available in various cities. These have metadata registered informing citizens what services are provided,
and how payments can be done. This enables you as a citizen, to pick providers that use modern technologies
such as crypto-currencies, and which merchant that integrates into the Smart City Platform. This enables
you to have a more detailed transaction history, than what you otherwise would have.
Humans often have a need to have their voice heard. Part of that, is the ability to vote on issues of concern. As either
a citizen, or employee, we want to feel we have an impact on major decisions being made.
Part of the Smart City Platform, will be the voting framework, which will enable anyone to create voting polls, that will
be both transparent, secure and anonymous (if needed). You as the user of this service, can set and configure
how you want to a voting to be executed.
The voting framework will be used by the Liberstad Incubator Program (LIP), to allow investors to vote on suggested applications
to the incubator program. It will also be used by the City Chain Foundation, allowing individuals who hold
City Coins to vote on issues, suggestions and more.
Registry built on blockchain for property registrations will be part of the Smart City Platform, likely through integration
with other existing blockchains built for the specific purpose of property registrations.
There are already governments that have started using blockchain for property registrations, and what is important on the
Smart City Platform, is for citizens to be able to see their properties and all the details that belongs
Some relevant news:
As an owner of vehicles, you will be able to register your vehicles on the City Hub. Integration with either/or both the
carVertical will ensure that you, have access too all the relevant details and history of your vehicles.
Insurance is an important part of a modern society, helping individuals, families and business survive the unforseen.
There are existing established and under development, insurance-platforms on blockchain technologies. The Smart
City Platform will be built with integrations into existing insurance blockchain platforms, allowing citizens
and others to get insurance coverage easy and seamless. Etherisc and Insurepal are two potential platforms
for insurance integration.
In life we have many different contracts that we have signed with others. This module on the Smart City Platform,
gives you an overview of all your contracts that are enacted on blockchain-technologies. You can additionally
upload and safely store copies of contracts that you scan.
This module also allows you to import the details of any token-based smart contracts you have purchased. In the first version
support for Ethereum will be added, and other smart contract platforms might be supported in the future based
on user demand.
Life in the city often involves subscriptions that have a recurring payment. This module on the Smart City Platform,
gives you insight into all subscription contracts you have, either with the city services, or with any other
Most of the time today, we as citiziens don't know much about the services we subscribe to, what payment and service plans
we subscribe to, and others details. Some services only supply some details through regular mail, while others
have limited self-service ability through their websites. We need to login at every individuals service,
with no easy overview and control.
The promise of the subscriptions module on the platform, is the ability to get better insight into your existing subscriptions,
and improved visibility into possible subscriptions available in the city and beyond.
Examples on subscriptions you might have stored on the platform, includes waste services, water services, city-bicycle rental,
city-car sharing and more.
Digitizing and verifying academic credentials will be part of the platform. This can be used as a foundation
for corporations to validate employment candidates, and it can be used by private or public educators to
give cryptographically verifiable certifications.
Note regarding third party integrations
Third parties that the Smart City Platform will integrate with, is not necessarily associated partners with City Chain. For
most third party integrations, we will rely on public available APIs. Listing of third party logos is not
Not all planned integrations are currently available, for example car VIN blockchains are currently ongoing
ICOs. As the market matures, we will reconsider which integrations we will do.
