The popularity of Bitcoin and blockchain technology applications certification blockchain technologies reached new heights in Bitcoin is the blockchain technology applications certification prominent blockchain technology applications certification a new type of currency, called cryptocurrency, where transactions are made without an established intermediary i.
Cryptocurrencies have functionalities akin to other currencies but are not blockchain technology applications certification to a nation-state like conventional currencies. The underlying architecture, blockchain, is able to leverage the capability of a global, open network combined with cryptologic theory for generating a secure, trust-less means of exchanging value or information 1,4.
Blockchain blockchain technology applications certification has vast applications across many food industry areas, especially traceability, logistics, and finance 1,8. Blockchain technology is a new iteration of an old concept. Ledgers are an inherent tool of business, and blockchain uses technology to improve on some of the disadvantages of private ledgers, namely by reducing reliance on external institutions in favor of cryptologic proof 1,7,8.
With blockchain distributed on a mutually shared network, all stakeholders of a supply chain can be on the same page with Key Data Elements KDEsthe essential pieces of information to convey traceability goals.
The following year, Nakamoto created Bitcoin based on this concept 1. Although the initial iteration of blockchain technologies concentrated on creating non-institutional currency, the technology is essentially a ledger with a wide potential of features, depending on the architecture 1. A blockchain uses hash-based cryptology to assure security and trust 4,5. A hash is an encrypted version of a string, or sequence of characters, wherein it is computationally impossible to derive the original without a key 5.
The blockchain has three essential pieces of data: Each transaction is then distributed throughout the network 4,5. Through this process, a continuous encrypted record of the transaction is kept and becomes immutable once added to the blockchain 4,5. To verify changes to the blockchain, a resolving algorithm audits the pending transaction after which it is then distributed throughout the network to the shared ledger 3.
Once a transaction has become finalized through this validation process, it becomes a permanent part of the chain. Blockchain architectures primarily differ in their choice in resolving algorithms 3. Some algorithms prioritize decentralization and anonymity while other prioritize throughput and rapidity 3. Users of the blockchain have two keys: The public key is the means for sending material to a specific individual on the blockchain.
The private key authenticates transactions from the individual holder. The technology has heavy interest among financial and supply chain technology companies, for its ability to rely on peer-to-peer networks rather than centralized institutions 1.
By having a more transparent and decentralized system, companies along the supply chain will be able to input data into the system with a degree of anonymity and control that may spur universal adoption 8. Data verification derived from its cryptologic structure is another attractive quality blockchain technology applications certification blockchain systems 8. The value of blockchain use in traceability systems is predicated on the rapidity of querying the system, the simultaneous capabilities of anonymity and transparency, and the immutable and shared nature of the system.
The concern with a centralized system to traceability includes a single point of breakdown, the opacity of such a system, and basis on the trust of the provider blockchain technology applications certification.
Blockchain has the potential for disparate parts of the food supply chain to input data into a shared ledger that reaches both ends of the market, from producer to consumer 8. Companies can input traceability information while keeping important proprietary or business-competitive information hidden 8.
IFT Global Food Traceability Center As ofsupply chain and traceability solutions using blockchain technologies have only been implemented in limited pilot studies 3,6. Some of these pilot studies combine other technologies, such as internet-enabled sensors 2. Many of the benefits touted for blockchain enabled systems are not necessarily exclusive.
By using a distributed system that is not implicitly owned by a particular entity, adopting common KDEs may be easier. However, it is possible to have KDEs that are harmonized across an industry while using more piecewise approaches to data collection and dissemination. The popularity of Bitcoin has revealed some drawbacks that will need to be addressed before being broadly applicable to industries like logistics or food traceability.
One is the inherent compromises that exist in blockchain, such as limited transactions per second, which has created bottlenecks in exchanging information 3,4,8. To scale a blockchain schema for an industry that processes thousands to millions blockchain technology applications certification transactions a second, these types of bottlenecks are unacceptable 8.
There is also an issue with latency, or the time needed to append a block of data blockchain technology applications certification the chain 8. As with any technology innovation, interoperability will be instrumental in ensuring implementation.
For blockchain, that will blockchain technology applications certification agreeing on a common platform to be used throughout a given supply chain. After all, blockchain is merely enhancing the existing business and transactional relationships in an industry. There will also still be a need for standardizing KDEs. As with any new technology, there are bound to be blockchain technology applications certification businesses using blockchain technology as a dubious value-added service.
For an analogy, e-commerce blockchain technology applications certification proliferated in the s during the dotcom boom, but many made poor business decisions while too heavily relying on the promises of new technology, an infamous example being pets.
Therefore, if one is investing in a blockchain technology to enhance traceability, it is important to have healthy skepticism on how effective blockchain is being implemented as a supply chain solution. Be wary of any promises that seem extraordinary. Cryptocurrencies are not strictly necessary to using blockchain in supply chains, so be especially skeptical about companies asking to invest in cryptocurrency.
Blockchain is not a silver bullet solution, especially to the sector of food traceability. Virtually every venture that is using blockchain technologies is still in its infancy, and there are many factors not dictated by technology that are affecting adoption. However, the potential for improved traceability by way of increased transparency, interoperability, and deinstitutionalization may prove invaluable to finding solutions among the issues in food traceability.
