In today's rapidly changing digital landscape, businesses are continuously looking for technology that will provide them an advantage, and blockchain is quickly emerging as a game changer. However, like any new technology, it presents both opportunities and challenges for businesses. Those who are familiar with the crypto world have heard about the Enterprise use case. Many assume that blockchains will reach maximum adoption when enterprises start using this technology. Some even accuse organizations of being short-sighted and even malicious for not adopting blockchains. While there is some truth on this, the reality is that organizations have many reasons to stay away.
The opportunities are tremendous. Blockchain technology provides unprecedented openness, security, and efficiency, all of which are essential in today's interconnected global economy. It offers real-time transaction tracking, which improves supply chain transparency and efficiency. It also offers unrivalled security, lowering the danger of fraud and cybercrime.
But the challenges are real. Implementing blockchain technology requires substantial investments in infrastructure and skills. There are also legislative issues to manage, as well as the need for standards in how blockchain is used across industries. Companies manage competitive situations; they do not want the competition to know how much they spend on contracts or how they conduct business. Employees do not want their information made public, and businesses do not want to engage in tactics that could jeopardize their market position.
Despite these limitations, blockchain's benefits to businesses significantly outweigh the expenses. Businesses that fail to embrace this breakthrough technology risk falling behind as their competitors move ahead.
Opportunities for Enterprises
Decentralization and Immutability
Incorporating a decentralized mechanism can create a tamper-proof system, enhancing security and trust within enterprises [1]. The immutability mechanism of blockchain ensures the integrity and quality of data, leading to improved information completeness and quality maintenance.
Transparency and Trust
Blockchain technology fosters transparency and trust by providing a distributed ledger approach that can improve the media supply chain, reduce copyright infringements, and solve real-time problems in various industries, including healthcare, logistics, manufacturing, and information technology [2].
Use Cases in Various Industries
Blockchain technology has real-world applications in supply chain and logistics, insurance, finance, and digital identity verification. For instance, blockchain-based applications in supply chain and logistics can greatly improve management by enabling faster and more cost-efficient delivery of products, traceability, coordination between partners, and access to financing [3] [4]. In the insurance sector, blockchain technology improves security, efficiency, and transparency across various activities, particularly in insurance claims processing [4].
Challenges and Solutions
Transitioning to Blockchain
Transitioning from conventional business models to blockchain necessitates a substantial reorientation, and stakeholders may resist this shift, leading to a slower pace of widespread blockchain adoption in enterprises [5]. Effective pilot projects and a gradual changeover strategy can help ease the reorientation process and win over stakeholders, enabling a more seamless transfer to blockchain technology.
Security and Scalability Issues
Several strong blockchain systems are plagued by compromised security and scalability expectations. Businesses encounter challenges in identifying solutions that meet their unique security and scalability needs. Working with leading enterprise blockchain development firms to create specialized solutions can help address these concerns and ensure that the blockchain platform smoothly conforms to the business’s unique needs [6].
A Potential Solution - ZK-Proof Technology
Zero-knowledge proofs (ZK-proofs) are a growing success story in cryptography and blockchain, with numerous applications including increased transaction privacy and scalability. ZK technology enables two parties to agree that a claim is genuine without disclosing any specifics about the claim, hence improving privacy and secrecy in blockchain transactions [7]. While ZK technology is still growing and faces security difficulties, it has enormous potential for addressing privacy and security concerns in blockchain applications. In my opinion, the advancement of this technology has the potential to alter the balance in favor of organizations using public blockchains.
How Zero-Knowledge Proofs Work
At a high level, a zero-knowledge proof works by having the verifier ask the prover to perform a series of actions that can only be performed accurately if the prover knows the underlying information. If the prover is only guessing as to the result of these actions, then they will eventually be proven wrong by the verifier’s test with a high degree of probability [8].
A simple example of how to intuitively understand proving data in zero knowledge is to imagine a cave with a single entrance but two pathways that connect at a common door locked by a passphrase. Alice wants to prove to Bob she knows the passcode to the door but without revealing the code to Bob. To do this, Bob stands outside of the cave and Alice walks inside the cave taking one of the two paths (without Bob knowing which path was taken). Bob then asks Alice to take one of the two paths back to the entrance of the cave (chosen at random). If Alice originally chose to take path A to the door, but then Bob asks her to take path B back, the only way to complete the puzzle is for Alice to have knowledge of the passcode for the locked door. This process can be repeated multiple times to prove Alice has knowledge of the door’s passcode and did not happen to choose the right path to take initially with a high degree of probability [9].
Companies like Nuggets and Mina use ZKPs to allow users to identify themselves with verified real-world information that does not compromise their personal data. Even financial institutions like ING Bank have implemented the use of ZKPs, allowing their clients to provide proofs such as proving the amount of money in their bank account without revealing the amount in a mortgage application, or proving that they live in an EU country without revealing the country [10].
Why Enterprises Should Adopt Public Blockchain Technology
Blockchain technology offers unparalleled opportunities for businesses to enhance transparency, efficiency, and security across various industries. While both private and public blockchains have their merits, enterprises should strongly consider adopting public blockchains for several compelling reasons.
First and foremost, public blockchains provide a higher level of decentralization and immutability compared to private blockchains. By leveraging a decentralized network of nodes, public blockchains ensure that data remains tamper-proof and resistant to manipulation. This heightened security is crucial for enterprises dealing with sensitive information and financial transactions. In contrast, private blockchains, while offering some level of control, are more susceptible to centralized authority and potential data breaches.
Moreover, public blockchains foster greater transparency and trust among stakeholders. With a distributed ledger accessible to all participants, enterprises can enhance collaboration and streamline processes across various industries, such as supply chain management, insurance, finance, healthcare, and digital identity verification. For instance, using a public blockchain, a supply chain network can track goods from origin to destination, reducing fraud and increasing efficiency. This level of transparency is more challenging to achieve with private blockchains, which limit access to a select group of participants.
Another significant advantage of public blockchains is their potential for interoperability and standardization. As more enterprises adopt public blockchain technology, the development of industry-wide standards becomes more feasible. This standardization can lead to seamless integration between different blockchain networks, enabling cross-industry collaboration and innovation. Private blockchains, on the other hand, often operate in silos, limiting their ability to interact with other networks and hindering the growth of a broader blockchain ecosystem.
Furthermore, the emergence of zero-knowledge proof (ZKP) technology is a game-changer for enterprises considering public blockchains. ZKPs allow businesses to prove the validity of transactions or data without revealing sensitive information. This technology addresses privacy concerns while maintaining the benefits of public blockchain transparency.
Examples of Private and Public Blockchains for Enterprises
Enterprise Ethereum: Ethereum’s underlying blockchain, Ethereum, offers a private blockchain service known as Enterprise Ethereum, enabling businesses to leverage Ethereum-based private chains and the public mainnet.
Hyperledger Fabric: Hyperledger Fabric is utilized by companies for track-and-trace of the supply chain, loyalty and rewards, clearing and settlements of financial assets, and more. For instance, Walmart uses a private blockchain system based on Hyperledger Fabric for supply chain management.
