Is Blockchain the missing internet link? Reality, Integration, Adoption and Mainstream

The internet changed the way we live, it opened the ways of unlimited communication and revolutionised access to information, but it failed greatly in regards to our personal digital freedom. Instead of providing trust, granted privacy, security, auditability, peer-to-peer communication, simplification and digital money, it evolved into a system of global intermediaries, that manipulate our private data and charge a percentage for every interaction. There is a new technology at the horizon called blockchain, that in its core excludes any intermediary’s, it brings peer-to-peer communication, online trust, security, privacy, authenticity, identity, synchronize ledger and much more. Could this be the long-awaited solution that could upgrade the internet and how it’s evolving?

Keywords: internet, digital transformation, cryptocurrency, blockchain technology, decentralisation, peer-to-peer, online trust, online security, online privacy, libra

Introduction

As an answer to 2008 global financial crisis Bitcoin was created, as a decentralised, independent digital cash network, that operated above the internet, out of banks and institutional reach. Soon the innovation of its backing technology (i.e. blockchain) was discovered as it could offer permissiveness solution to online privacy, security, digital identity, authenticity, peer-to-peer transactions and much more.

Blockchain Recognition and Adoption by Constitutional Organizations

To achieve fastest worldwide adoption several challenges should be overtaken; (1) establishment of legal regulatory and governance framework that could be adopted worldwide; (2) synchronise the competing interests, and; (3) achieving infrastructure replacement or upgrade.

Adoption by Big Banks and Big Tech

It took a few years for the Big Banks and Big Tech to officially acknowledge cryptocurrencies, blockchain technology and discard the offence position. The benefits of technology are just too hard to dismiss.

The Mainstream Adoption

To achieve blockchain global scale adoption, there are still open network issues to address like transaction cost, scalability and energy consumption.

Conclusion

The possibility to enable access to financial instruments to over 1.7bn underbanked people is truly revolutionary. Blockchain could solve open questions in the fields of finance, insurance, notary functions, supply chain management, identity, privacy and digital rights management, IoT (i.e. internet of things), state administration, online security, seaborne cargo tracking, 4D printing, quantum computing, augmented data discovery, machine learning, autonomous driving, virtual reality and much more.

Initial steps toward blockchain enterprise adoption

Blockchain has been acknowledged and recognised also in the mainstream enterprise sector. With its ability to improve online trust, transparency, efficiency and cut the middle man, blockchain solutions are developing at a light speed with the potential to revolutionise enterprise digital communication and collaboration. With major benefits to create, store and exchange sensitive information like electronic data and documents, blockchain can substantially change the technological landscape as we know it. This article clarifies the basic steps towards blockchain enterprise adoption and acts as a guideline using two suitable project use-cases as examples; (1) HashNet as an advanced scalable blockchain network, and; (2) 4thtech as a blockchain application suite, that leverages trust provided by the blockchain to provide secure, immutable, instant cross-border electronic data and document exchange and eDelivery.

Keywords; blockchain, enterprise, adoption, private chain, public chain, DLT, hashnet, 4thtech, digital identity, electronic data exchange, document notarisation

The landscape & Opportunity

According to PwC Time to trust Report 2020, blockchain has the potential to boost global domestic product (i.e. GDP) by 1.76 trillion dollars over the next decade and hit the mainstream by 2030.

Blockchain Technology

With major benefits to create, store and exchange sensitive information like electronic data and documents, blockchain can substantially change the technological landscape as we know it.

Blockchain Networks

Every blockchain transaction is executed by a blockchain network such as Bitcoin, Ethereum, Tolar HashNet, Polkadot and others. Every network has its own characteristics, so it all comes down with the project requirements.

Blockchain Enterprise Ecosystem

Establishing a viable ecosystem is another key requirement prior to blockchain implementation.

Private versus Public

Public blockchains allow anyone to read or write to the public charged ledger, while private Enterprise blockchains can restrict access to their network partners.

GDPR Compliance

While the data protection EU authorities have not yet concluded which blockchain approaches deliver GDPR compliance, possible solutions are already emerging.

Interoperability

According to the EU blockchain forum report, blockchain platforms will need to be able to communicate and share data, which is a property usually referred to as interoperability.

Blockchain Digital Identity

Trusted identities of blockchain participants are crucial to the operation success and can enable complex transactions and reduce risk.

Blockchain Electronic Data Exchange

The need for immutable, unmodifiable digital data and documents exchange is imminent. E-mail is not appropriate, non-secure and does not fulfil the task in question.

Blockchain Document Notarisation

Notarisation can be described as a fraud prevention process that enables document authenticity and guarantees that the document has not been changed in the course of a transaction between parties.

The 4thpillar Technologies (i.e. 4thtech) Whitepaper

Based on 10 years of experience from the human resource industry, creation of new possibilities in the field of blockchain technology and the need for sensitive document exchange and digital identity,  the idea behind 4thtech presented itself. Dr. Rezun started to develop the 4thtech initiative in the year 2017. In October 2018 working BETA was released proving the founder’s theory. A working product is online and available for testing. The whitepaper is the essential project document, project blueprint where the ideas are constructed and the foundations are made. Over 200+ project whitepaper versions were written before the finished version.

Keywords: 4thtech, 4thpillar technologies, blockchain, DLT, digital identity, electronic data exchange, document notarisation

Introduction

Exchanging sensitive documentation or merely digital assets should be as easy as exchanging information. Blockchain technology proposes the ideal foundation to make this a reality.

What & Why?

The 4thtech products combine several advanced technologies and deliver blockchain-based EU compliant solutions, more specific 4thtech solves document exchange and digital identity challenges. 4thtech infrastructure combines unique functions and functionality that can be easily applied to any industry.

Solutions

4thtech leverages trust provided by the blockchain to provide secure, immutable, instant cross-border electronic data and document exchange and eDelivery. Additional Notarisation features enable users to access the document time-stamp and verify its authenticity via file checksum. 4thtech identification mechanism verifies and maps the connection between a blockchain wallet and a person, utilising the X.509 digital certificate standard

Innovation

The project's main innovation is revealed from the fact that the blockchain electronic data and document exchange protocol and Notarisation Service does not store the transmitted electronic data and documents on the blockchain. The electronic data and documents are stored off-chain. The protocol records links to encrypted files and hashes of the encrypted content on the blockchain.

Artificial Intelligence is here! Reality, Integration, Research, and Adoption

Artificial Intelligence (i.e. AI) is already a part of our lives. It impacted the way we interact, shop, travel, work, do business and challenge our society and culture, while becoming a vital part of self-driving cars, trucks, healthcare diagnostics, IoT, stock market, surveillance, military, agriculture, advanced manufacturing, robotics, etc. Artificial Intelligence has the potential to be the next step towards a new industrial revolution and can change human evolution altogether, but with all that disruptive change, big questions and topics are emerging, that will sooner or later need to be addressed; (1) human versus machine dilemma; (2) What is intelligence?; (3) Will Artificial Intelligence enhance our life or threaten our survival?; (4) How will AI change the nature of our jobs?

Keywords: artificial intelligence, ai, internet, digital transformation, big data, singularity, machine learning, neural networks

Introduction

Artificial Intelligence history goes to 1930s when the Turing machine was invented, that could, in theory, do all the calculations that humans were able to do. According to Max Little (2017), the practice started to take off later when AT&T labs invented a transistor and the microchip, and with that started an era of microcomputers.

Intelligence Defined

The definition of intelligence is controversial, some groups of psychologists have defined it as; A very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience.

The Technology Behind AI

WIPO (2019), devised a framework of AI understanding, dividing AI-related technologies to three groups; (1) machine learning; (2) functional application, such as speech recognition and computer vision, and; (3) telecommunication and transportation.

Future Jobs, Adoption, and Integration

In the 1980s, Owen (1988) envisioned AI possibilities in; (1) farming, using computer-controlled robots, that could control pest, prune trees and harvest mixed crops: (2) manufacturing, where computer-controlled robots could execute dangerous and boring assembly, inspections and maintenance jobs; (3) medical care, where computers could help with diagnosis, monitor patients, manage treatment and make beds, and; (4) household work, where machines could mow the lawn, do the laundry and perform maintenance chores.

Conclusion

Artificial Intelligence is here! Reality, Integration, Research, and Adoption research article and overview tries to shed some light on the AI open questions. The article tried to establish, the relation between nature and machine and provided the reader's facts to draw their own conclusions. For now, one thing is clear, nature and machines cannot be equal.

Research Methods

This study employs qualitative and quantitative or mixed methods.

Data Collection

Qualitative data were collected in several ways.

Significance of the Study

This study seeks to test a model that could possibly assist companies in developing a successful online marketing presence on their websites. By applying the model to their companies, marketers and marketing campaigns can better position company brands in highly competitive new social media (SM) environments.

Assumptions and Limitations

There are six assumption and limitations of this study.

Research Business Model, Dr. Tali Rezun

Conceptual business effect model on the positive effect of firm generated problem solving content on social media and online brand equity

This model is a general online business model, derived from observation and extant theories which may be adopted by small and medium-sized companies, (b) the model and its underlying theory provided general guidance for online support building brand equity and online business exposure, and (c) the model offers detailed support, general guidance, and an explanation of proposed processes to SMEs companies, though other industries may take alternate approaches when applying the model.

There are few available and proven business models available about online marketing in the fast-paced, quickly changing global online business environment. Many companies lack the knowledge to adapt and to support online business development (Ha, 2005). To address the problem, a business model was developed as part of doctorate dissertation (i.e. Company Generated Problem-Solving Content on Social Media (SM) and Online Brand Equity: Designing and Testing a Model for Its Effectiveness A dissertation submitted in partial fulfilment for the degree of Doctor of Business Administration) to help companies develop successful online marketing campaigns and to position their brands in existing new social media environment.

The results from testing the model showed positive results on higher brand equity and exposure and resulted in better business performance and overall recognition in the targeted region. This confirmation of the model is one of the major contributions of related study because it maps a possible path and process for other companies to follow and modify accordingly. The model is effective, is easy to use, and is suitable for use by other companies.
