Blockchain technology has captured the world's imagination, primarily due to its association with cryptocurrencies and non-fungible tokens (NFTs). However, blockchain offers a plethora of use cases that go beyond digital currencies and tokens. In this article, we delve into the less-explored realms of blockchain, discussing its potential applications in supply chain management, the concept of Web3, and the misconceptions and challenges surrounding its implementation.
Blockchain: More Than Just Cryptocurrency
Cindy Vestergaard, VP of special projects and external relations at blockchain API company RKVST, reminds us that the birth of blockchain predates the Bitcoin whitepaper. Estonia, for instance, was exploring distributed ledger technology (DLT) for securing citizen services and protecting data even before Bitcoin gained popularity. Although blockchain is one type of DLT, it has become so synonymous with cryptocurrency that people often overlook other forms of DLT.
Martha Bennett, VP and principal analyst at Forrester, distinguishes between permissioned and permissionless blockchains. While permissionless (public) blockchains support cryptocurrencies, permissioned blockchains are designed for enterprise applications.
Blockchain in Supply Chain Management
Blockchain technology is especially useful in scenarios involving multiple parties where data accuracy and immutability are crucial. It's no surprise that supply chain management is one area where blockchain can significantly enhance transparency and efficiency.
Companies such as Walmart and De Beers have already implemented successful blockchain initiatives for food traceability and diamond sourcing. Walmart's partnership with IBM resulted in a blockchain-based food traceability system that reduced the time to trace produce from days to seconds. On the other hand, De Beers introduced its Tracr blockchain platform to guarantee the ethical sourcing of diamonds, providing end-to-end traceability throughout the supply chain.
Blockchain can be used to verify the authenticity and originality of photos or files. This immutability, security, and shareability have numerous potential applications.
The Advent of Web3
Web3 is an ambitious concept that envisions a decentralized and blockchain-based internet, empowering users to own their data and ensuring secure digital transactions. The Web3 Foundation, a non-profit organization, is spearheading this movement. Although the idea is in its infancy, Web3 promises to revolutionize how we interact with the internet.
However, some experts predict that Web3 won't replace the current web infrastructure (Web 2.0) by the end of the decade, as it faces challenges like potential security threats, lack of customer protection, and a possible return to centralized control. One prominent driver can be Internet Computer (ICP) by DFINITY but still in the early stages.
The Current State of Blockchain Adoption
A recent Stack Overflow survey ranked blockchain technology as moderately proven and impactful. Meanwhile, a Foundry survey found that 51% of respondents were not interested in adopting blockchain within their organizations. Interest in researching technology has also declined over the years.
Despite the lukewarm reception, the enterprise has had successful blockchain implementations. Financial sector is leading one of the initiatives besides other use cases.
The Environmental Impact
Blockchain technology, particularly the energy-intensive Proof of Work (PoW) consensus mechanism used by cryptocurrencies, has faced criticism for its environmental impact. However, alternative consensus mechanisms, such as Proof of Stake, promise to significantly reduce energy consumption. The Ethereum network's migration to a Proof of Stake blockchain, for example, has slashed its energy consumption by 99.95%.
The Overpromise of Blockchain Technology
One major concern with blockchain technology is the overpromise of its benefits. Companies need to be cautious when considering the adoption of blockchain technology and focus on their objectives rather than the technology itself. In many cases, the benefits attributed to blockchain are actually due to digitization, not the blockchain aspect.
Blockchain technology undeniably offers promising applications beyond cryptocurrencies and NFTs. Its potential in supply chain management and the concept of Web3 demonstrates that it has a bright future. However, companies must exercise caution and focus on their goals before jumping on the blockchain bandwagon. With a clear vision and a practical approach, businesses can harness the power of blockchain technology to revolutionize their industries.
