Eth utilizes blockchain technology
Blockchain technology , the distributed ledger system that underpins the digital currency Bitcoin, is getting a lot of attention from Wall Street lately. With uses ranging from cross-border payments to settlements and clearing of over-the-counter derivatives to streamlining back-office processes, the potential for disruption in the financial industry and elsewhere is growing more real each day. Ethereum was developed to augment and improve on bitcoin, expanding its capabilities. Its blockchain is built with a turing-complete scripting language that can simultaneously run such smart contracts across all nodes and achieve verifiable consensus without the need for a trusted third party such as a court, judge or legal system.

Open access peer-reviewed chapter. In the rapidly evolving environment of the international supply chain, the traditional network of manufacturers and suppliers has grown into a vast ecosystem made of various products that move through multiple parties and require cooperation among stakeholders.
Additionally, the demand for improved product visibility and source-to-store traceability has never been higher. Blockchain technology has shown promising results for improving supply chain networks in recent applications and has already impacted our society and lifestyle by reshaping many business and industry processes. In an effort to understand the integration of blockchain technology in the supply chain, this paper systematically summarizes its current status, key characteristics, potential challenges, and pilot applications.
The supply chain plays a crucial role in modern businesses by allowing them to achieve efficiency, responsiveness, and success. Over the past several decades, the scale of businesses has expanded, the number of geographic locales involved in the production process has grown, and product portfolios have diversified. As a result, the supply chain has grown from a traditional network of manufacturers and suppliers, to a vast ecosystem made of various products that move through multiple parties and require cooperation among stakeholders [ 1 ].
Additionally, due to the rapid evolution of e-commerce, the demand for improved product visibility and source-to-store traceability has never been higher. However, the inefficiency of data sharing in current supply chain networks has dramatically impacted the operations of retailers and manufacturers.
For example, information gaps between data collected by factories and by retailers make it challenging to trace product history and offer customized products. To overcome these challenges and improve supply chain performance, industries have explored innovative technologies that support efficient collaboration and coordination within and among different organizations [ 2 , 3 ].
Among these technologies, blockchain provides a promising future and allows the supply chain to provide better visibility, transparency, and acuity of transactions throughout the entire process [ 4 ]. The blockchain technology that powers cryptocurrency has caught the attention of businesses, especially those in supply chain management. Although blockchain-based applications in the supply chain are still in their early stages, we believe this technology will significantly remodel the supply chain system [ 6 , 7 , 8 ].
Analysts forecast that blockchain technology can help supply chain management gain one-third improvement in most of its common processes [ 9 ]. A blockchain network is as a distributed ledger—transactions are contained in blocks that are linked together in chronological order to form a tamper-proof chain, which is usually stored in all network nodes [ 10 , 11 ].
As such, blockchain technology provides a means to create tamper-proof logs of business activities and transactions [ 12 ]. Transaction data are immutable because they cannot be tampered with once they are distributed, accepted, and validated by network consensus and stored in the blocks [ 13 ]. By eliminating intermediaries to achieve trust among all stakeholders, efficiency improves and cost is reduced for the entire supply chain. Despite the general acceptance that blockchain technology facilitates faster, more easily auditable interactions and allows for the exchange of immutable data among supply chain partners [ 14 ], it will take time for this technology to be adopted and to revolutionize the supply chain.
Currently, most applications of blockchain are conceptual expositions, and empirical evidence on the implementation of it is limited [ 15 ]. Furthermore, few studies have been conducted on the challenges of deploying blockchain in the supply chain, such as organizational readiness, technical expertise, scalability, and compatibility with existing systems. Therefore, this study will provide a systematic analysis of how blockchain technology fits in the supply chain network and discuss potential challenges with its implementation.
Supply chain encompasses the end-to-end flow, including the physical and correlated data flow of raw material, products, information, and money. It plays a unique and critical role in businesses and determines the performance of organizations. Supply chain manages or is involved in sourcing, procurement, manufacturing, distribution, and logistics, and, thus, affects speed-to-market, the cost of a product, service perception, and capital requirements in businesses [ 16 ].
Supply chain integrates a set of fragmented and often geographically discrete processes into a cohesive system to deliver value to the customer. The core functions and operations of a typical supply chain network are illustrated in Figure 1. Supply chain and operations. Evolving customer requirements, challenges from competition, geographically separated operations, and the adoption of new business models such as e-commerce make the current supply chain a highly complex system.
Over the past decade, e-commerce and hand-held digital devices have substantially changed the daily lives of people, especially in the ways they shop. There is an ever-increasing demand for customized products, a simplified and efficient shopping experience, and transparency about the value and provenance of goods. These needs bring new opportunities to businesses but impose significant challenges to current supply chains. These outdated supply chains struggle to improve demand management, to provide data visibility for the entire flow, or to track goods from raw material to end consumer—all of which are tremendously complex.
We summarize the main challenges in current supply chains here:. Lack of traceability : In the last few years, traceability has become crucial for supply chains to address, especially in regard to customer service and planning and forecasting in business operations.
However, it is difficult to deploy a centralized system in an interconnected network, especially where trust among participants is limited.
Instead, there are several discrete systems among involved parties that consist of various databases that impede product tracking throughout the entire supply chain network [ 17 ].
Stakeholder distrust : Trust is an essential factor in supply chain management, and an effective supply chain network must be built on a solid foundation of it [ 18 ]. However, distrust among participants is the single greatest obstacle to improving supply chain networks [ 19 ]. Consequently, most stakeholders in the network primarily rely on third-party intermediaries to serve as agents of trust and to verify transactions, which dramatically increase operational cost and reduce process efficiency.
A transparent supply chain network improves trust among stakeholders and guarantees the integrity of products and associated data. However, the discrete databases in current supply chain networks offer minimal transparency, and most of the useful information in them is lost when products and data are transferred from one stakeholder to another.
Furthermore, there are issues with inconsistent data sharing, relying on paper documentation, and inadequate interoperability. These critical challenges remain despite years of significant research investment. The crisis of Chipotle Mexican Grill outlets [ 7 ] is an important and sad example of how the current supply chain system is inefficient at, and possibly incapable of, offering transparency throughout the entire lifecycle of products.
Outdated means of data sharing : In current supply chain networks, data are shared between many organizations using paper-based documentation. Oftentimes, important documents, such as bills of lading, letters of credit, invoices, insurance policies, and various certificates, must travel with their associated goods around the world [ 22 ].
For example, about communications were needed for Maersk, a global transport and logistics company, to complete a single shipment of frozen goods from Mombasa to Europe in [ 23 ]. These communications created a stack of documents about 25 centimeters in height [ 24 ]. Constrained by this outdated and inefficient data sharing method, ships and airplanes are often delayed in ports when the paperwork does not match the carried goods [ 22 ].
Compliance challenges : Currently, businesses have to meet increasingly strict regulatory standards to provide safe products and services to customers. Recently, the U. Food and Drug Administration and Federal Trade Commission adopted several standards to increase food safety and offer full visibility of food flows in the supply chain. However, under current supply chain processes, it is difficult to obtain this information from a variety of stakeholders and to develop a database that complies with new standards.
Blockchain is an innovational technology that enhances customer service, drives end-to-end value, and increases the efficiency of operations [ 25 ]. Additionally, it allows distrusting or unfamiliar stakeholders to create shared and secure data records [ 26 ]. In sum, when an exchange of valuable data and goods is necessary, blockchain technology expedites transactions, streamlines the process, enhances transparency, reduces waste, and, ultimately, reduces cost [ 27 ].
Consequently, new types of internet and associated business models have been built off of this robust technology [ 22 ]. Blockchain promises to be the primary driver of secure and efficient economic and social systems in the future.
The basic concepts of blockchain were introduced by Satoshi Nakamoto in Bitcoin [ 28 ], a digital cryptocurrency that can work without the need of a trusted intermediary. It offers a distributed ledger that tracks and sustains a tamper-proof record of transactions in a decentralized network. In essence, it is a unique database system that is created, replicated, synchronized, and maintained by all participants in the decentralized network.
Blockchain operates in a decentralized peer-to-peer network [ 29 ] to validate and store all transactions in a consensus that is agreed upon by all nodes in the network, without any central authority to validate the transaction as with an intermediary. All completed and validated transactions are logged in the distributed ledger in a verifiable, secure, transparent, and permanent manner along with a timestamp and other details [ 30 ].
In this way, the exchange of tangible and intangible data and assets among participants can be recorded digitally. Each stakeholder maintains a copy of the synchronized ledger, which prevents a single point of system failure or data loss [ 22 ]. When changes are made, such as adding a new block, all copies in the network are simultaneously updated, and records are permanently registered in all ledgers [ 31 ]. These changes are stored into blocks that create a chain [ 32 ], where a block is linked to the preceding one by storing its hash a unique data that is mapped from the given block [ 33 ].
Figure 2 shows the fundamental chained architecture of a blockchain network. The architecture of a data chain in a blockchain network. In Figure 2 , notice that except for the first block called the genesis block , each block has its hash as a unique ID that includes the hash of the previous block. In this way, a chronological chain is formed. Additionally, the hash mechanism provides enhanced data security.
Usually, a block stores a set of time-stamped transactions that are validated by stakeholders in the network. Once it gains consensus, the block is accepted and stored by all parties in the blockchain and can no longer be modified. Therefore, trust in and transparency of transactions between organizations are significantly improved. Since the introduction and success of Bitcoin, many blockchain-based platforms can be categorized as either a permissionless or permissioned blockchain.
Virtually, anyone can join and participate anonymously in a permissionless blockchain network. Accordingly, it is also called a public blockchain, and these two notions will be used interchangeably in the remaining sections. Within this type of network, trust among users is limited or nonexistent. To overcome this lack, miners detailed later are introduced to validate transactions.
In contrast, permissioned blockchain is a network for a group of identified users operating under a governance model, called a consensus, to improve transactional trust. To join this type of network, new users need permission from the majority of the group or a delegated user; hence, it is also called a private blockchain, and we use both notions interchangeably in this paper. These networks facilitate trust among users and do not require costly miners.
More efficient consensus protocols such as the Byzantine fault tolerant protocol validate data, improve network throughput, and reduce the latency of transactions. Blockchain technology has many unique features that allow for the creation of a verifiable, secure, transparent, and immutable distributed ledger, the core characteristics of which are summarized as follows: Versatile value exchange : Blockchain provides a secure and efficient platform for recording the transactions of intellectual property rights, the provenance of services and goods, asset ownership, cryptocurrency exchange, and more.
Distributed governance : A blockchain network is not controlled by any designated authority, organization, or person, and the need for trusted intermediaries to verify transactions is eliminated.
It is a distributed database that provides secure and validated data for all participants in the network simultaneously. Thus, there is full transparency along the entire stream of transactions, and assets and data can be transferred between several organizations in a quick and efficient way.
Decentralized architecture : The ledger is decentralized and stored in all nodes i. Therefore, it fosters a robust network that improves the quality, reliability, and availability of services and information. Logically centralized : With only one transaction record shared with and agreed upon by all participants, a blockchain network behaves like a logically centralized system.
Data transparency : Blockchain technology allows for a highly transparent network that is visible to each stakeholder at all times. This dramatically reduces the chances of illegal transactions. Immutable data : Once a block with a set of transactions is verified by the consensus and stored in the chain, the encapsulated data can no longer be modified. Enhanced data security : Blockchain technology utilizes asymmetric cryptography and digital signature algorithms to ensure data security and individual identity.
To cater to the vastly different needs of unique businesses and users, many blockchain networks are created, and each contains a slightly different set of features; however, a basic foundation remains the same for all.

Inside the Jordan refugee camp that runs on blockchain
Blockchain technology can enhance the basic services that are essential in trade finance. At its core, blockchain relies on a decentralised, digitalised and distributed ledger model. By its nature, this is more robust and secure than the proprietary, centralised models which are currently used in the trade ecosystem. Blockchain technology creates a viable, decentralised record of transactions — the distributed ledger — which allows the substitution of a single master database.
Deploying Blockchain Technology in the Supply Chain
A new technology is redefining the way we transact. If that sounds incredibly far-reaching, that's because it is. Blockchain has the potential to change the way we buy and sell, interact with government and verify the authenticity of everything from property titles to organic vegetables. It combines the openness of the internet with the security of cryptography to give everyone a faster, safer way to verify key information and establish trust. Blockchain technology was originally developed as part of the digital currency Bitcoin. But the two are not the same.

Blockchain is best known as a sophisticated and somewhat mysterious technology that allows cryptocurrencies to change hands online without assistance from banks or other intermediaries. But in recent years, it has also been promoted as the solution to business issues ranging from fraud management to supply-chain monitoring to identity verification. A few pioneers in retail and other sectors are exploring blockchain business applications related to supply-chain management and other processes, but most are reluctant to proceed further because of high costs, unclear returns, and technical difficulties. But we may now be at a transition point between Blockchain 1. In the new era, blockchain-enabled cryptocurrency applications will likely cede their prominence to blockchain business applications that can potentially increase efficiency and reduce costs. These applications will be in a good position to gain steam since many large tech companies may soon begin offering blockchain as a service BaaS. As blockchain deployment becomes less complex and expensive, companies that have sat on the sidelines may now be willing to take the plunge. Think of blockchain as a database shared across a number of participants, each with a computer.

By Yoruk Bahceli. The two-year bond, registered in the public ethereum blockchain network, priced for a yield of Funding officials at the EIB told Reuters this was the first time a syndicate of banks had managed such a sale, adding that the bank wanted the deal to resemble a conventional bond issue as much as possible. Companies and supranational borrowers such as the EIB sell most of their bonds through such syndicated, multi-dealer sales. Many capital market players see blockchain, originally created to run the bitcoin cryptocurrency, as a way to streamline the issuance of securities like bonds and equities. The traditional capital-raising process is expensive and inefficient, involving numerous steps and multiple parties, and proponents say using blockchain could cut costs, time and boost transparency.
