Why interoperability is important in smart cities and how blockchain empowers them?
Two key reasons why smart cities are getting so much attention are the rise of societal concerns linked with increased urbanisation and the growing need to decrease public budgets. Between 2018 and 2030, the number of cities with populations of 10 million or more is predicted to rise from 33 to 43, according to the United Nations. While urbanisation is supposed to deliver significant economic strength owing to population and industrial concentration, it also comes with concerns, such as increasing congestion and environmental issues.
Smarter cities are becoming more popular, and the economic depression brought on by COVID-19 necessitates more efficient urban administration than than before. Between 2020 and 2024, the smart city market, which includes energy, healthcare, and security, is predicted to increase at a 23 percent annualised rate, reaching $2.1 trillion.
Advanced technology, such as blockchain, can help to solve these societal problems and achieve effective urban management. Without the need for a single administrator, blockchain allows network participants to share data with a high degree of reliability and transparency. crypto smart city
"In order to obtain the greatest possible long-term outcomes, initiatives should be proactive in their preparation around interoperability issues."
For this data exchange, blockchain is likely to be used. Smart Dubai is researching blockchain use cases across a variety of industries, including finance, education, and transportation, as part of its ambition to make Dubai the happiest and smartest city on the planet. For example, a blockchain-based project to simplify enrollment procedures for students transferring between emirates is now underway.
It's crucial to note that having autonomous smart cities isn't enough for smart cities to contribute to societal challenges and to run efficiently while enhancing service quality. Rather, ensuring interoperability and coordination among multiple smart cities is critical.
Efforts to achieve this goal are already underway. In March 2020, Japan's cabinet office produced a white paper on smart city reference architecture, citing interoperability as one of four key ideas in the promotion of smart cities. crypto smart city
The G20 Global Smart Cities Alliance, whose secretariat is the World Economic Forum, brings together municipal, regional, and national governments, private-sector partners, and city residents around a common set of core guiding principles for smart city technology implementation, including openness and interoperability.
A recently published framework for interoperability, which proposes a three-layer paradigm for blockchain application, can help smart cities.
1. The governance, data standards, legal frameworks, and commercial models layers are all part of the business model layer.
2. Consensus methods, smart contracts, authentication, and permission are all part of the platform layer.
3. Hybrid cloud, managed blockchain, and proprietary components make up the infrastructure layer. It's worth noting that attaining interoperability necessitates more than just solving a technological issue; it also necessitates addressing governance, data ownership, and commercial business models.
Right Time To Invest In VVM Coin
THE VVM COIN AND RPP
The internal, tradeable, asset-backed VVM Property Participation (RPP) for use on our Crowdfunding platform is built on two units of value: our innovative cryptocurrency VVM Token, which can be held in any Ethereum Smart Wallet, and the internal, tradeable, asset-backed VVM Property Participation (RPP) for use on our Crowdfunding platform. The Real Estate Asset Ledger Token (VVM) is a secure Blockchain digital asset with built-in vesting.
VVM Tokens are created through a Token Sale Smart Contract and can be stored in any Ethereum ERC20 wallet. Because VVM Tokens are an ERC20 Token with inherent value in exchanges, they will be traded outside of the VVM platform. VVM Tokens can also be used to purchase Real Estate Participations (RPP), which can then be traded.
Long Term Vision
People pick a variety of assets as a store of value, a transactional medium, or an investment around the world. For transacting, storing, and accounting these assets, blockchain is a better system. Most estimates place global wealth at roughly $250 trillion, with banks and other financial institutions holding the majority of it.
The conversion of these assets to cryptocurrency is a fantastic opportunity.
VVM, we feel, will be a significant milestone in the cryptocurrency industry, contributing to the ascent of cryptocurrencies as people lose faith in fiat money and other traditional measurements of wealth, like as real estate.
We believe that VVM Tokens will be more appealing than traditional Real Estate investments since Tokenized ownership will make Real Estate more liquid.
We also believe that, in the near future, VVM technology will make all property-related transactions safer, more transparent, and quicker.
Because of its connection to one of the best performing real world assets: real estate, we believe the VVM Token will provide stability, security, and a more precise evaluation of value and perceived risk of cryptocurrency value. crypto smart city
