How Blockchain Can Solve Major Issues In Supply Chain Management

A blockchain can be defined as “a decentralised database that keeps an ever-expanding series of ordered records, referred to as blocks.” These blocks are “interconnected through cryptographic methods. Each block includes a cryptographic hash of the preceding block, a timestamp, and transaction details.” Essentially, a blockchain serves as a public, distributed digital ledger utilised for documenting transactions across numerous computers, ensuring that the records cannot be modified retroactively unless all subsequent blocks are changed and there is agreement within the network.

According to Wikipedia, “Blockchain was created by Satoshi Nakamoto,” an alias for an unidentified individual or group, “in 2008 to function as the public ledger for bitcoin transactions… [which] enabled it to be the first digital currency capable of addressing the double-spending dilemma without relying on a trusted authority or central server.”

While its primary application remains in the documentation and management of transactions for cryptocurrencies like Bitcoin, advocates of blockchain technology are exploring additional applications, such as:

– Payment processing and money transfers via blockchain: Transactions conducted on a blockchain could be completed in seconds and significantly lower (or altogether remove) bank transfer fees.

Supply chain monitoring using blockchain: Businesses could swiftly identify inefficiencies in their supply chains, track items in real-time, and assess product quality as they move from manufacturers to retailers.

– Digital identity management with blockchain: Microsoft is investigating how blockchain technology can empower individuals to manage their digital identities while controlling access to their personal information.

– Data sharing facilitated by blockchain: Blockchain could serve as a secure intermediary for storing and transferring enterprise data across various industries.

Utilising Blockchain for Copyright and Royalties Protection: Blockchain technology can facilitate the development of a decentralised system that guarantees musicians retain their rights to their work while also enabling clear and immediate royalty payments. This approach could benefit open-source developers.

Employing Blockchain in the Internet of Things (IoT) Network Management: Blockchain has the potential to oversee IoT networks by identifying devices connected to wireless systems, tracking their activities, and evaluating their reliability. It could also automatically verify the trustworthiness of newly added devices, such as vehicles and smartphones.

Implementing Blockchain in Healthcare: Blockchain could significantly enhance operations in the healthcare sector, as both healthcare payers and providers are leveraging this technology to manage data from clinical trials and electronic medical records while ensuring compliance with regulations.

What Advantages Does Blockchain Offer Businesses?
While the primary advantage of blockchain lies in its capacity to serve as a transaction recording database, its advantages surpass those of conventional databases. Most importantly, it eliminates the risk of tampering by malicious entities and offers several business benefits:

Efficiency Gains: Blockchain dramatically reduces transaction processing times from days to mere minutes, as it does not require validation from a central authority.

Cost Efficiency: Blockchain minimises the need for extensive oversight, allowing participants to trade valuable items directly. It also removes redundant efforts since all parties have access to a unified ledger.

Enhanced Security: The security mechanisms inherent in blockchain safeguard against tampering, fraud, and cyber threats.

Understanding Blockchain

According to “Blockchain for Dummies,” the term “blockchain” refers to its method of data storage, where transaction information is organised into interconnected blocks to create a continuous chain. As transactions increase, the blockchain expands accordingly. Each block documents and verifies the timing and order of transactions, which are recorded within a defined network that operates under mutually agreed-upon rules among its participants.

Every block includes a hash (a unique digital signature), a timestamp of recently validated transactions, and the hash of the preceding block. This connection through the previous block’s hash ensures the integrity of the chain, making it impossible to alter any existing block or insert a new one between two blocks. This structure makes the blockchain resistant to tampering.

The fundamental principles of blockchain are:

1. Shared Ledger: A shared ledger is a distributed record-keeping system that allows only additions, creating a single source of truth across a business network. This approach prevents redundant efforts that often occur in conventional business systems.

2. Permissions: Permissions play a crucial role in securing transactions, ensuring they are authenticated and verifiable. By controlling who can participate in the network, organisations can better adhere to regulations such as HIPAA and GDPR regarding data protection.

3. Smart Contracts: Smart contracts are predefined agreements or rules governing business transactions, stored on the blockchain and executed automatically during a transaction.

4. Consensus: Consensus mechanisms enable all parties to agree on transactions verified by the network. Blockchains employ various consensus methods, including proof of stake, multi-signature, and practical Byzantine fault tolerance (PBFT).

Within each blockchain network, different participants fulfill various roles, including users of the blockchain.

Blockchain Participants
– Users: These are typically business individuals who possess the necessary permissions to access the blockchain network and engage in transactions with other users.
– Regulators: Speciallyauthorisedd users tasked with monitoring and overseeing the transactions occurring within the network.
– Network Operators: Individuals endowed with specific permissions and responsibilities to design, create, manage, and supervise the blockchain network.
– Certificate Authorities: Professionals responsible for issuing and managing the various certificates needed to operate a permissioned blockchain.

Hyperledger Overview
Hyperledger is a collective initiative encompassing open-source blockchains and associated tools. It was launched in December 2015 by the Linux Foundation, with backing from industry leaders like IBM, Intel, and SAP. It aims to foster the collaborative development of blockchain-based distributed ledger technologies.

Participants in Hyperledger advocate that only an open-source, collaborative approach to software development can guarantee the transparency, durability, interoperability, and support necessary for the mainstream adoption of blockchain technologies.

The primary goal of the Hyperledger project is to enhance collaboration across different industries by creating blockchains and distributed ledgers. It emphasises improving the efficiency and reliability of these systems compared to traditional cryptocurrency models to facilitate global transactions for major companies in technology, finance, and supply chains.

Security in Blockchain
Blockchain is often touted as an “unhackable” technology; however, vulnerabilities such as 51% attacks can allow malicious actors to seize control of over half of a blockchain’s computational power, thereby compromising the integrity of its shared ledger. Although executing this type of attack is both costly and challenging, its potential effectiveness underscores the need for security experts to view blockchain as a valuable technology rather than a panacea for all issues.

The 51% attack exploits a phenomenon referred to as the 51% problem: “When one entity controls 51% of a mining pool, it can manipulate entries in the blockchain, enabling double spending and even the creation of a new chain that benefits the mining pool.”

Public and private blockchains provide varying degrees of security. Public blockchains “validate transactions through computers connected to the public internet, grouping them into blocks for addition to the ledger. In contrast, private blockchains generally allow only recognised organisations to participate.” Due to the open nature of public blockchains, they may not be suitable for businesses that prioritise the privacy of data flowing through the network.

Another distinction between public and private blockchains lies in participant identity. Public blockchains “are often built on the principle of anonymity. Conversely, a private blockchain is a permissioned network where consensus is reached via ‘selective endorsement,’ whereby known users authenticate transactions. This arrangement benefits businesses by ensuring that only authorised individuals can manage the transaction ledger. While there are still potential risks from insiders, many can be addressed with a robust security framework.”

Blockchain technology is advancing rapidly, giving rise to innovative applications in areas ranging from shared storage solutions to social networking platforms. From a security standpoint, we are venturing into new territory. As developers work on blockchain applications, they must prioritise the security of these systems. Essential activities include conducting risk assessments, developing threat models, and performing various code analyses such as static code analysis, interactive application security testing, and software composition analysis—all crucial components of a developer’s blockchain strategy.
