Introduction
Blockchain technology originated in 2008. The narrow blockchain technology is a non- tamper-able and unforgeable decentralization that combines data blocks into specific data structures in chronological order and cryptographically guaranteed. By sharing the general ledger, it is possible to securely store simple, hierarchical data that can be verified within the system. The generalized blockchain technology uses encryption technology to verify and store data, use distributed consensus algorithms to add and update data and use code running on the Blockchain, i.e. smart contracts, to ensure automatic enforcement of business logic. A new multi-centred infrastructure and distributed computing paradigm were implemented (Michael et al., 2018).
The core advantage of blockchain technology is that it no longer needs a traditional centralization mechanism. It only implements peer-to-peer transactions that do not depend on a credit centre in distributed systems through encryption, consensus mechanisms, timestamps, and other technical means. Coordination and collaboration circumvent issues common in centralized organizations, such as data security, synergy efficiency and risk control. Since becoming famous, Bitcoin has been hailed as a revolutionary technology that will change the world's financial landscape. Although the extreme nature of Bitcoin is not as good as that of ATMs and PayPal, its impact on society is undeniable (Pilkington, 2016: 225).
The innovative change in financial technology has been a process for decades, which began in 1970. According to a recent report by Business Insider Intelligence, financial technology innovation is a continuous development process. Its impact can be said to be greater than Automatic Teller Machine (ATM) and PayPal and even more significant than the role of Bitcoin in the financial system. ATMs have changed how people interact with banks, achieving a degree of automated trading, and the emergence of PayPal has reduced people's reliance on banks in savings and transfer transactions. However, holders of PayPal accounts will still be required to deposit funds in their accounts using traditional payment methods. In this regard, Bitcoin brings a new level of rule breakthrough. Its characteristics show that banks will be replaced under the general development trend (Yli-Huumo et al., 2016).
At the moment, Bitcoin may not be able to replace the bank completely, but it shows such potential. The financial development of the new era today depends on Bitcoin. More precisely, it depends on its underlying technology, Blockchain, and many startups are now exploring it. A recent report entitled "Financial Technology Ecosystem Report: Measuring the Impact of Technology on the Entire Financial Services Industry" provides a new perspective on the future of financial technology.
It depicts a war between an existing financial powerhouse and a startup that aims to transform decades of traditional machines. Like all other wars, there will always be winners and losers; in the end, it will only wait and see who the winners are. For example, the long-standing war is ongoing – such as the confrontation between traditional banks and online banking systems, the conflict between the conventional and Peer to Peer (P2P) markets, crowdfunding and formal funding or management and competition between robot consultants, etc. (Wright & De Filippi, 2015)
These cases show that new alternatives, including Blockchain, are technology-driven and require minimal human intervention. According to this report, future banking, lending and finance; payments and transfers; wealth and asset management; markets and exchanges; insurance, blockchain trade and other areas will undergo significant changes.
Before Blockchain
For decades, attempts have been made to decentralize money and make the economic system a more fluctuating environment. The first known attempts to integrate the science of cryptography with electronic money resulted in Digi-cash and E-cash, coins that used cryptography to anonymize money transactions; nevertheless, the issuance and settlement were still centralized. These first attempts are attributed to the computer science David Chaum.
The concept of cryptocurrency was born and coined by Wei Dai in 1998 when it was officially proposed to create a new type of decentralized money that would use cryptography to control. However, it was not until 2009 that the first cryptocurrency known and used in the technological world was created: Bitcoin. This first cryptocurrency was created by a developer -or group of developers- under the pseudonym of Satoshi Nakamoto (Mettler, 2016: 1).
If we briefly review history, we will see, as always, that a relevant technological improvement has taken place there has been a revolution in finance. After the appearance of the paper, it was the Chinese who created the paper currency. Understanding what allowed them to trade at a greater distance without carrying gold is essential. The technology that made the credit card or ATM possible also offered new forms of economic exchange. And now, the globalization that underlies the Internet and the development of Blockchain technology opens the door to a new way of making transactions; Disintermediated, immediate, accessible and more reliable (Atzori, 2015).
Blockchain Changing the Market
First, it is difficult to tamper with and is more secure. In the security scheme of traditional information systems, security relies on access control of layers of defense. Through blockchain technology, the database of recorded transactions can be accessed by anyone. Still, due to the clever design and supplemented by cryptography and consensus mechanisms, the data logging of the Blockchain makes it necessary to change all subsequent data records to modify specific data. It is challenging. The practice has proved that such a database can ensure that Bitcoin, with a market value of hundreds of billions of dollars, is stable under the attack of global hackers (Underwood, 2016: 15).
The second is heterogeneous and lively, with high reliability. Each system participant in the Blockchain is a multi-site living node, a natural multi-live system. If a node encounters a network problem, hardware failure, or software error or is controlled by a hacker, it will not affect the design and other participating nodes. The nodes in the Blockchain interact through a peer-to-peer communication protocol. Different nodes can use different programming languages and versions of the total nodes to process transactions when other communication protocols are guaranteed. The resulting software heterogeneous environment ensures that even if there is a problem with a version of the software, the overall network of the Blockchain will not be affected, which is the cornerstone of its high availability (Lemieux, 2016: 110).
The third is to have a smart contract and execute it automatically. Smart contracts have the advantages of transparency, credibility, automatic execution, and mandatory compliance. Despite this, since the introduction of Nick Saab in 1993, smart contracts have remained at the conceptual level. The critical reason is that no environment has supported trusted code running for long, and automatic enforcement is impossible. For the first time, Blockchain made intelligent contracts a reality.
The fourth is the network direct cooperation mechanism, which is more transparent. The Blockchain provides a different method from the traditional way of connecting participants in a peer-to-peer manner. The participants jointly maintain a system. The responsibilities of the participants are clear, and there is no need to transfer rights to third parties, which is beneficial to all parties. As a trusted machine, the Blockchain is expected to become a new mode of cooperation with low cost and high efficiency, forming a new collaborative mechanism with enormous scope and lower price (Zheng et al., 2017: 557).
Since the launch of Ethereum in 2015, blockchain technology has been undergoing rapid development, and business scholars have begun to link blockchain technology with the idea of a sharing economy. The ethical marketing logic that operates within the blockchain-based sharing economy is essential. This shift outlines the principles of stakeholder capitalism. Therefore, activities and practices that are ethically based in marketing increase collaborative marketing. It innovates value chains and develops sustainable business models in the sharing economy and the Metaverse (Tan & Salo, 2023).
Blockchain is the Disruptive Innovation
The proposed blockchain applications' characteristics are decentralization, network-wide, distributed anti-destruction, intelligent contracts, and evidence-based incentive mechanisms. Researchers said that if the fundamental innovation of the Blockchain is the evolution of bookkeeping technology, then the Blockchain can be called disruptive innovation in the accounting sense for 500 years (Sun et al., 2016: 26).
The importance of distributed ledgers lies in the ability to deliver value and construct a credible technology (transfer value and further evolution). The distributed ledger must judge the application scenario under the current technology bearer. The business affairs and supervision department business is a suitable application, mainly in sharing, de-media, de-intermediation, business association and input-output. At the same time, it is proposed that although the Blockchain is at an early stage, its potential for the next generation of distributed networks and applications is already evident; in the use of Blockchain to enhance trust and avoid fraud, it is necessary to follow legal rules (Sikorski et al., 2017: 234).
Based on the combination of Blockchain and artificial intelligence, it should share answers, not data. Artificial Intelligence (A.I.) makes it possible to avoid sharing raw data, so blockchain technology is still developing. Trust and privacy issues can be better solved in the future, especially when algorithms and data are separated. Finally, it has been pointed out that artificial intelligence enhances productivity, blockchain restructuring of production relations, cloud computing, and big data are the future production materials and targets (Ølnes, 2016: 253).
It is one of the main advantages of using and applying the Blockchain. In a system such as health, in particular, the application of this model would prevent, for example, the use and implementation of inadequate treatments while increasing monitoring, control and safety throughout the process of care for each patient; This would reduce the costs for health providers at the same time due to factors as diverse as the provision of medicines, insurance management and the use of information from people.
The medical scenario is one of those that could benefit most from using and applying Blockchain. In the United States, for example, more than 250,000 deaths per year are caused by doctors' mistakes. Monitoring tools would allow even greater control over medical records and the same use of work equipment in laboratories, surgery rooms, etc., dramatically reducing patient risks (Raval, 2016).
Notably, in the United States, deaths due to errors of this type are equivalent to the second cause of death after heart disease. Putting this in context, Colombia could take advantage of new models such as Blockchain in the medical sector and others, innovating in the application and use of new technologies.
It will be started by trying to explain what Blockchain technology consists of. Blockchain technology is becoming fashionable and allows us to validate the veracity of transactions (Malinova & Park, 2017).
When a transaction exists, it must be approved (consensually) by the participants. These participants are previously named by an "administrator" and respond to the "technical" name of "miners". If all participants approve the transaction (this occurs in seconds), it is integrated into an accounting book, guaranteeing that it will never be modifiable. The novelty of this process is that no central authority is necessary since they are the participants themselves (miners, to be more exact) who give validity to the system (Sikorski et al., 2017: 234).
Blockchain: Success or Failure?
Blockchain technology is often referred to as the "next internet." The current Blockchain is to the Internet in the 1990s and is still in the initial stage of development. Still, the emergence of this kind of technological means will undoubtedly bring about earth-shaking changes in social life. In the future, more complex smart contracts will solve the problem of trust between people, people and machines, machines and machines, extend the application of Blockchain to all areas of social life, improve the overall efficiency of society, and promote social collaboration (Yli-Huumo et al., 2016).
For example, Blockchain can help the Internet of Things achieve decentralized control. The critical issue affecting the development of the Internet of Things (IoT) is data management: in the centralized network mode, with the increase in access devices, huge maintenance investment will be generated, and user privacy protection also has hidden dangers. Blockchain technology can establish a low-cost direct communication bridge between these devices and improve the security and privacy of the system through a decentralized consensus mechanism. Home dishwashers can issue a "smart contract" to give orders, require detergent suppliers to supply, and, after receiving shipment information from the retailer, notify them by phone ringtone, reminding the host (Wright & De Filippi, 2015).
Blockchain technology is expected to change the way the real estate market operates. Buying a house is a significant event in life, and the procedures and procedures are very complicated. Consumers often have to pay high agency fees to ensure transaction security. Blockchain technology can be applied to real estate purchases, custody, and ownership transfer. Establishing a secure and shared ownership database for the real estate industry simplifies the transaction process, enhances transaction security, reduces real estate transaction disputes, and reduces transaction costs (Underwood, 2016: 15).
Blockchain can be combined with artificial intelligence. On the one hand, the artificial intelligence network based on Blockchain can set consistent and effective device registration, authorization and perfect lifecycle management mechanism, which is beneficial to improve the user experience and security of artificial intelligence devices; on the other hand, artificial intelligence is also able to realize the management of the Blockchain, discover the natural evolution of the parameter model and the transaction model, integrate the application service, and optimize the service rules (Zheng et al., 2017: 557).
The Blockchain can also build a mutual trust mechanism for insurance so that future insurance returns to the mutual aid model. People with a shared risk protection need can join a mutual help community managed by a smart contract, acting as an insured when they are at risk and acting as an insurer when others in the community are at risk. Once someone in the community has met the terms of the contract, the contract will automatically implement the prescribed deduction process to protect the rights of the participants (Sikorski et al., 2017: 234).
While optimistic about the prospects of the Blockchain, we must also see the challenges blockchain technology faces in practical applications, including regulatory approaches, technology gaps, security, privacy protection, and flexibility. In this critical opportunity period of the development and application of Blockchain, we need the joint efforts of all sectors of society to strengthen investment in policies and regulations, economic investment and scientific research innovation and be prepared to wait patiently for the disruptive changes brought by the Blockchain (Ølnes, 2016: 253).
Blockchain Technology is gaining footholds not only in the banking industries, and it is likely to disrupt other industries such as the Healthcare, Real Estate, Legal Industry, Security, Government, Education, Rentals and Ride Sharing, Charities and Aid Organizations and Politics. Many projects are being investigated to implement the Blockchain as a structure to become a valuable technology for now and in the future.
Blockchains are distributed in tamper-evident and tamper-resistant digital ledgers. Blockchains allow a community of users to record transactions in a shared register that cannot be modified under standard blockchain network functioning. Modern cryptocurrencies, cryptographically secured electronic cash, were created in 2008 by combining Blockchain with numerous other technology and computer principles. Blockchain-based Bitcoin was the first. Electronic money is linked to a Bitcoin blockchain address. Bitcoin users can digitally sign and transfer rights to that information to another user, which the Bitcoin blockchain records publicly, allowing all network participants to authenticate the transactions independently. Distributed participants administer the Bitcoin blockchain. Combined with cryptographic techniques, this protects the Blockchain from later changes to blocks or transactions (Yaga et al., 2019)
