Abstract
Keywords:
1. Introduction
2. Blockchain Technology: This Is the Background on the Creation of Cryptocurrency
2.1. How Blockchain Works
- -
- Decentralization: It is different from financial systems that work through the verification of transactions through centralized units like banks; the system is backed by a swarm of computers, called nodes. All the nodes store the whole blockchain database to make sure that no single entity can manage the whole network.
- -
- Consensus Mechanisms: The blockchain networks use consensus for the purposes of validating transactions in the network while ensuring their security. The two common consensus mechanisms that are popular among the cryptocurrencies are the Proof of Work (PoW), and the Proof of Stake (PoS). While in PoW miners are using computational power to validate the transactions and add blocks to the chain, in PoS validators are selected depending on the number of tokens that they are willing to ‘stake’.
- -
- Immutability: After appending a block into a blockchain, nobody can alter or even delete any record found within that block without the approval of the other network members. This immutability assures that records of other transactions are permanent and cannot be altered in any way thus increasing security and enabling more confidence.
- -
- Transparency: Each of the operations that takes place within a blockchain is put into a public registry that is available to all stakeholders. This makes the system very transparent, in a sense that if anyone would like to cross check the transactions that have been recorded on the blockchain they easily can [7,8].
2.2. Most Important Uses of the Blockchain System
- -
- Security: A hashing function along with consensus mechanisms provide the immutability of the content stored in the blockchain. The agreements reached on the blockchain must be replicated on many nodes, which is very challenging for the wrong actors to do.
- -
- Transparency and Trust: When it comes to the information dissemination within the public blockchains, such as in bitcoins and ethereum every transaction is transparent. It builds trust because users are able to assess the authenticity of exchanges on the block chain without the need for third parties [9].
- -
- Decentralization: Blockchain gets rid of the middlemen since it provides for direct buyer-seller transactions. This reduces dependence on central authorities such as banks or other financial related institutions since users control their assets fully at all times.
- -
- Efficiency and Automation: Blockchain has the capability of automating contracts through smart contracts, program tokens that contain terms of a contract which are executed once certain conditions are met. Such contracts can be implemented when certain trigger terms are initiated and do not require a middleman and involve shorter transactions [10].
2.3. Blockchain’s Contribution in Facilitating Cryptocurrencies
2.3.1. Bitcoin and Proof of Work (PoW)
2.3.2. Ðioskoh Ethereum and Smart Contracts
2.4. Blockchain Beyond Cryptocurrency
- -
- Supply Chain Management: Blockchain implemented ensures that supply chain gets full transparency and real-time tracking in intervals from the manufacturer to the consumer. This minimizes cases of fraud because there is check and balance system in organization.
- -
- Healthcare: Valid blockchain application in healthcare can enhance data confidentiality and patient’s privacy by storing their medical records in the blockchain. It gives patients an authority to allow a healthcare provider access to his/her records which will contain the right information as well as privacy [13].
- -
- Government Services: Blockchain’s applications are also being considered by governments to enhance the functionality and the accountability of government agencies, for instance, in the land registries, voting and identification processes. Recently, blockchain has emerged as a solution to cut down on red tape and diminish chance for fraud.
- -
- Decentralized Finance (DeFi): DeFi refers to decentralized finance that is currently a burgeoning industry and operates through the utilization of Blockchain technology. It enables users to lend, borrow or trade within P2P marketplace system without involving the traditional third parties such as banks hence expanding the market [14].
2.5. Limitations of Blockchain Technology
- -
- Scalability: As more and more transactions take place on the block chain the efficiency of the system decreases and congestion rises. Some networks like the Bitcoin and Ethereum have had a problem with scalability that comes with expensive transaction fees and slow transactions.
- -
- Energy Consumption: First, the PoW such as the one used by Bitcoin is very computationally intensive and therefore very expensive in terms of energy. This has made some people question the environmental friendliness of blockchain platforms especially those with vast distribution.
- -
- Regulation and Legal Uncertainty: Blockchain and cryptocurrencies are currently without well-defined legal and regulatory oversight, thus providing an environment that is not ideal for business and investors. Governments are still experiencing difficulties in how to control this decentralised technology; the legal issues involved; data protection; security and taxes [15].
