The aim of using this technique is to secure the transaction of distributed ledgers in a database and to protect records from tampering, fraudulent activity, and corruption by the chain participants. The blockchain technology approach offers an efficient security measure and novel advantages, such as in the transaction existence and distribution ledger management between the depot, transporter, and retailing filling station. Others advantages are transparency, immunity to fraud, insusceptibility to tampering, and maintaining record order. The technique adopted for this secure distributed ledger database is crypto hash algorithm-1 (SHA-1)-based public permissioned blockchain and telematics, while this telematics approach is an embedded system integrated into an in-vehicle model for remote tracking of geolocation (using Global Positioning System (GPS)), monitoring, and far-off data acquisition in a real-time. The scope of the data in the secure distributed ledger database (using blockchain) developed are identification (ID) of the tanker operator, Depot name, Source station ID, Destination station ID, Petroleum product volume, Transporter ID, and Geographic automobiles location. This system proved to be efficient, secure, and easy to maintain as it does not permit any individual for records tampering, but supports agreement of ~75% of participants in the chain to make changes. Keywords: blockchain; database; petroleum product; security; telematics 1. Introduction In the last decades, oil and gas (petroleum product) have been key sources of revenue, liveliness, and industries for the national economy and its development [1]. Nigeria is recognized as one of the highest ranked petroleum product exporting countries in the Organization of the Petroleum Exporting Countries (OPEC) eleven [2]. However, the distribution process of this product in Nigeria has been a great challenge over the years and generally caused fluctuation in the country’s economy. These challenges are fuel scarcity, oil and gas hijacking, inflation in price, and many others. The disruption in the supply of this inflammable resource in Nigeria has been a habitual problem as its distribution has a multitude of problems. Aminu et al. proposed petroleum products (oil and gas), aside from other occupation practices in the marketing supply chain, are generally an imperative source of energy globally, and represent a major part of the economies of most developed nations, including USA, UAE, Saudi Arabia, and so on [3]. One of the reasons for this product scarcity in the nation was due to the transaction’s susceptibility to corruption, fraud, and lack of transparency among the parties J 2019, 2, 300–325; doi:10.3390/j2030021 www.mdpi.com/journal/j J 2019, 2 301 J 2019, 2, x 2 of 26 involved in the supply chain and distribution process [4].

    26 CFR 1.61-1: Gross income. (Also §§ 61, 451, 1011.) Rev. Rul. 2019-24 ISSUES (1) Does a taxpayer have gross income under § 61 of the Internal Revenue Code (Code) as a result of a hard fork of a cryptocurrency the taxpayer owns if the taxpayer does not receive units of a new cryptocurrency? (2) Does a taxpayer have gross income under § 61 as a result of an airdrop of a new cryptocurrency following a hard fork if the taxpayer receives units of new cryptocurrency? BACKGROUND Virtual currency is a digital representation of value that functions as a medium of exchange, a unit of account, and a store of value other than a representation of the United States dollar or a foreign currency. Foreign currency is the coin and paper money of a country other than the United States that is designated as legal tender, circulates, and is customarily used and accepted as a medium of exchange in the country of issuance. See 31 C.F.R. § 1010.100(m). - 2 - Cryptocurrency is a type of virtual currency that utilizes cryptography to secure transactions that are digitally recorded on a distributed ledger, such as a blockchain. Units of cryptocurrency are generally referred to as coins or tokens. Distributed ledger technology uses independent digital systems to record, share, and synchronize transactions, the details of which are recorded in multiple places at the same time with no central data store or administration functionality. A hard fork is unique to distributed ledger technology and occurs when a cryptocurrency on a distributed ledger undergoes a protocol change resulting in a permanent diversion from the legacy or existing distributed ledger.

  • Blockchain & Distributed Ledger Technologies
    Science, Technology Assessment, SEPTEMBER 2019 and Analytics WHY THIS MATTERS Distributed ledger technology (e.g. blockchain) allows users to carry out digital transactions without the need SCIENCE & TECH SPOTLIGHT: for a centralized authority. It could fundamentally change the way government and industry conduct BLOCKCHAIN & DISTRIBUTED business, but questions remain about how to mitigate fraud, money laundering, and excessive energy use. LEDGER TECHNOLOGIES /// THE TECHNOLOGY What is it? Distributed ledger technologies (DLT) like blockchain are a secure way of conducting and recording transfers of digital assets without the need for a central authority. DLT is “distributed” because multiple participants in a computer network (individuals, businesses, etc.), share and synchronize copies of the ledger. New transactions are added in a manner that is cryptographically secured, permanent, and visible to all participants in near real time. Figure 2. How blockchain, a form of distributed ledger technology, acts as a means of payment for cryptocurrencies. Cryptocurrencies like Bitcoin are a digital representation of value and represent the best-known use case for DLT. The regulatory and legal frameworks surrounding cryptocurrencies remain fragmented across Figure 1. Difference between centralized and distributed ledgers. countries, with some implicitly or explicitly banning them, and others allowing them. How does it work? Distributed ledgers do not need a central, trusted authority because as transactions are added, they are verified using what In addition to cryptocurrencies, there are a number of other efforts is known as a consensus protocol. Blockchain, for example, ensures the underway to make use of DLT. For example, Hyperledger Fabric is ledger is valid because each “block” of transactions is cryptographically a permissioned and private blockchain framework created by the linked to the previous block so that any change would alert all other Hyperledger consortium to help develop DLT for a variety of business users.

  • Initial Coin Offerings: Financing Growth with Cryptocurrency Token
    Initial Coin Offerings: Financing Growth with Cryptocurrency Token Sales Sabrina T. Howell, Marina Niessner, and David Yermack⇤ June 21, 2018 Abstract Initial coin offerings (ICOs) are sales of blockchain-based digital tokens associated with specific platforms or assets. Since 2014 ICOs have emerged as a new financing instrument, with some parallels to IPOs, venture capital, and pre-sale crowdfunding. We examine the relationship between issuer characteristics and measures of success, with a focus on liquidity, using 453 ICOs that collectively raise $5.7 billion. We also employ propriety transaction data in a case study of Filecoin, one of the most successful ICOs. We find that liquidity and trading volume are higher when issuers offer voluntary disclosure, credibly commit to the project, and signal quality. s s ss s ss ss ss s ⇤NYU Stern and NBER; Yale SOM; NYU Stern, ECGI and NBER.

Part of this paper was written while David Yermack was a visiting professor at Erasmus University Rotterdam. 1Introduction Initial coin offerings (ICOs) may be a significant innovation in entrepreneurial finance. In an ICO, a blockchain-based venture raises capital by selling cryptographically secured digital assets, usually called “tokens.” These ventures often resemble the startups that conventionally finance themselves with angel or venture capital (VC) investment, though there are many scams, jokes, and tokens that have nothing to do with a new product or business.

  • Keys Are, As Their Name Suggests, a Key Part of a Relational Database
    The key is defined as the column or attribute of the database table. For example if a table has id, name and address as the column names then each one is known as the key for that table. We can also say that the table has 3 keys as id, name and address. The keys are also used to identify each record in the database table . Primary Key:- • Every database table should have one or more columns designated as the primary key . The value this key holds should be unique for each record in the database. For example, assume we have a table called Employees (SSN- social security No) that contains personnel information for every employee in our firm. We’ need to select an appropriate primary key that would uniquely identify each employee. Primary Key • The primary key must contain unique values, must never be null and uniquely identify each record in the table. • As an example, a student id might be a primary key in a student table, a department code in a table of all departments in an organisation. Unique Key • The UNIQUE constraint uniquely identifies each record in a database table. • Allows Null value. But only one Null value. • A table can have more than one UNIQUE Key Column[s] • A table can have multiple unique keys Differences between Primary Key and Unique Key: • Primary Key 1. A primary key cannot allow null (a primary key cannot be defined on columns that allow nulls). 2. Each table can have only one primary key. • Unique Key 1. A unique key can allow null (a unique key can be defined on columns that allow nulls.) 2.

    Cryptocurrency: The Economics of Money and Selected Policy Issues Updated April 9, 2020 Congressional Research Service https://crsreports.congress.gov R45427 SUMMARY R45427 Cryptocurrency: The Economics of Money and April 9, 2020 Selected Policy Issues David W. Perkins Cryptocurrencies are digital money in electronic payment systems that generally do not require Specialist in government backing or the involvement of an intermediary, such as a bank. Instead, users of the Macroeconomic Policy system validate payments using certain protocols. Since the 2008 invention of the first cryptocurrency, Bitcoin, cryptocurrencies have proliferated. In recent years, they experienced a rapid increase and subsequent decrease in value. One estimate found that, as of March 2020, there were more than 5,100 different cryptocurrencies worth about $231 billion. Given this rapid growth and volatility, cryptocurrencies have drawn the attention of the public and policymakers. A particularly notable feature of cryptocurrencies is their potential to act as an alternative form of money. Historically, money has either had intrinsic value or derived value from government decree. Using money electronically generally has involved using the private ledgers and systems of at least one trusted intermediary. Cryptocurrencies, by contrast, generally employ user agreement, a network of users, and cryptographic protocols to achieve valid transfers of value. Cryptocurrency users typically use a pseudonymous address to identify each other and a passcode or private key to make changes to a public ledger in order to transfer value between accounts. Other computers in the network validate these transfers. Through this use of blockchain technology, cryptocurrency systems protect their public ledgers of accounts against manipulation, so that users can only send cryptocurrency to which they have access, thus allowing users to make valid transfers without a centralized, trusted intermediary.
