What is Blockchain?

Title

  • Blockchain
  • https://link.springer.com/article/10.1007/s12599-017-0467-3

Objectives

  • define what is blockchain

Methodology

  • Synethesis

Implications

Why should we use Blockchain?

Title

  • How Blockchain Will Change Organizations
  • https://www.proquest.com/docview/1875399260?pq-origsite=gscholar&fromopenview=true

Objectives

  • Pursue people should use Blockchain

Methodology

  • Interviews

Results

  • The Role of Transaction Costs
  • Managing With Blockchain
  • What if there were an internet of value — a secure platform, ledger, or database where buyers and sellers could store and exchange value without the need for traditional intermediaries? This is what blockchain technology will offer businesses.
  • We believe that blockchain will transform how businesses are organized and managed. It allows companies to eliminate transaction costs and use resources on the outside as easily as resources on the inside.
  • Shareholders will be able to enforce the commitments executives make. Companies can specify relationships and state specific outcomes and goals so that everyone understands what the respective parties have signed up to do.

Implications

  • Human Resources and Procurement
  • Finance and Accounting
  • Sales and Marketing
  • Legal Affairs
  • Raising Capital

When should we use Blockchain?

Title

  • A Ten-Step Decision Path to Determine When to Use Blockchain Technologies

Objectives

  • the drawbacks of blockchain databases (e.g., scalability, capacity, latency, privacy) mean that the technology is not always appropriate
  • This article presents a ten-step decision path that can help determine whether the application of blockchain is justified and, if so, which kind of blockchain technology to use

Methodology

  • We describe how this decision path was used to develop a blockchain prototype for the Danish maritime shipping industry

Results

Implications

  • In suply chain logistics, it is essential to consider whether to apply the Blockchain in the domain?

Who should use Blockchain?

Title

  • Becoming a blockchain user: understanding consumers’ benefits realisation to use blockchainbased applications
  • https://www.tandfonline.com/doi/pdf/10.1080/0960085X.2021.1944823?needAccess=true

Objectives

  • What kind of procedures should be followed in pursue the customer in buying our product?

Methodology

  • use profile

Results

Implications

  • we know what is the customer’s journey in deciding what is the right technique to do

Why should we not use Blockchain?

Title

  • To Blockchain or Not to Blockchain: That Is the Question

Objectives

  • Why should we not use Blockchain?

Methodology

  • REVIEW

Results

  • Characterized by high power consumption. A Bitcoin transaction could cost $6 when considering the energy consumed by network nodes.15
  • Mining requires expensive hardware, and the majority of computing power is wasted. Mining blocks is a competition among nodes where only the quickest wins—the others are just wasting resources. To increase the probability of winning, nodes could join mining pools and collaborate with other nodes, sharing revenues. A solution to reduce the amount of necessary computing power could be to change the mining process from proof of work to proof of stake, where nodes can purchase the opportunity to mine using tokens, and mining power is proportional to the number of tokens owned. This way, mining would be less resource intensive but would be restricted to token holders.
  • Data replication requires space. Local copies of the blockchain (hence, of all transactions that have occurred since its creation—about 105 Gbytes for Bitcoin and 70 Gbytes for Bitcoin and Ethereum; http://bitinfocharts.com) are stored on each network node. Performances are therefore not yet comparable with databases.
  • Adding information is slow. Creating a Bitcoin block takes around 10 to 60 minutes (http://blockchain.info/charts/avg-confirmation-time). Ethereum requires 15 seconds, (http://etherscan.io/chart/blocktime), a smaller though still significant amount of time.
  • Immutability and transparency could harm users’ privacy and reputation. Every network node would store a copy of the blockchain and could possibly access its content.
  • Smart contracts cannot rely on external APIs. Every node should be able to process previous transactions and end with the same result as the other nodes. That is, information must be immutable. Consequently, data required by a smart contract should be first injected in the blockchain. Oracles can enable this injection, but require a strong reputation system or governance mechanism and need to be as robust as the blockchain itself, not to become the weakest part of the process.
  • Smart contracts can be buggy. Because their code is publicly available and they become autonomous entities once they are created, they could be “candy for hackers.”12 As they are stored on the blockchain, smart contracts cannot be modified. To remove code bugs, developers have to create new contracts and transfer all data and pointers from the old to the new ones. The most relevant case of a smart-contract-based attack happened on Ethereum in June 2016, when about $60 million was “stolen.”

Implications

  • Critical evaluation of the Blockchain based application for the domain

What is Blockchain’s current application in the domain of logistics?

Title

  • Blockchain Technology Implementation in Logistics

Objectives

  • What is Blockchain’s current application in the domain of logistics?

Methodology

  • Review

Results

Implications

  • Blockchain’s implication in the supply chain logistics

What is the Blockchian’s current joint application with Artificial Intelligence?

Title

  • A Systematic Literature Review of Integration of Blockchain and Artificial Intelligence
  • https://link.springer.com/chapter/10.1007/978-3-030-38181-3_8

Objectives

  • RQ1: What are the latest studies on the integration of Blockchain and AI?
  • RQ2: What are the AI use cases in Blockchain?
  • RQ3: What applications can benefit from the integration of AI and Blockchain?

Methodology

Results

  • We identified 69 primary studies relating to Blockchain use case mixed with AI until early 2019. These articles can be used in further studies for comparative analysis in this specific field.
  • We selected 23 studies for a comprehensive review and expressed the research ideas and contributions in the fields of Blockchain use cases mixed with AI.
  • We present the state of the art methods and contributions in which, integrating AI and Blockchain improves various types of applications.
  • We provide guidelines to support further work in this area.

Implications
