Blockchain technology is being hyped with vigor these days. It does hold promise for organizations engaged in international trade, and challenges, too. Could it be helpful to your organization?\r\n\r\nAs a quick aside, there is a lot of confusion of blockchains with \u201ccryptocurrencies\u201d like Litecoin and Bitcoin. Cryptocurrencies do use blockchain technology. But blockchains can be used in many other situations.\r\n\r\n \r\n<h3><strong>A Few Definitions and Descriptions<\/strong><\/h3>\r\nSo, what is blockchain, exactly?\r\n\r\nIn some ways, blockchains are analogous to very secure Google Docs. Think of a blockchain as business ledger, collectively updatable only by mutual agreement of the parties involved, always open to an interested party to inspect.\r\n<p style="padding-left: 30px;"><strong>Blocks<\/strong>. Each record, or bundle of records, in the ledger is called a \u201cblock.\u201d The blocks are time-stamped and organized in a chronological chain. Each block has a reference to the block before it and the new information that is to be recorded.<\/p>\r\n<p style="padding-left: 30px;"><strong>Hashes<\/strong>. You will frequently hear references to \u201chashes\u201d or \u201chash code\u201d in conversations about blockchain. A hash is a unique representation of a set of data\u2014you can think of it as a dataset\u2019s fingerprint. They are created by passing the data through a particular type of algorithm. Blockchains use hashes to confirm the relationship of one block to the next.<\/p>\r\n<p style="padding-left: 30px;"><strong>Cryptography<\/strong>. And each block is secured by cryptography. Cryptography is a mathematical method for making information unreadable to anyone who does not have a key for translating the encrypted information back into a standard format.<\/p>\r\n<p style="padding-left: 30px;"><strong>Distributed<\/strong>. This ledger is not stored on any single computer. Rather, it is stored across a network of participants\u2019 personal computers\u2014a set up that is called \u201cdistributed.\u201d No central entity or person owns the system. No centralized third-party authority (like a bank or a government) needs to validate the data in this ledger. All participants help run the ledger and can use it. In the case of Bitcoin, there are thousands of users. They assess transactions\u2019 validity (if half of participants agree a transaction is valid, it is considered valid) and earn a small fee for this service.<\/p>\r\nUse of hashes, cryptography, and distributed data make blockchains just about impossible to, fake, game, tamper with or destroy. What\u2019s written, is written\u2014accurate, enduring.\r\n\r\nAnd they are fast\u2014transactions are almost instant; recording them may take minutes.\r\n\r\n \r\n<h3><strong>Blockchains at Work<\/strong><\/h3>\r\nHere are some examples of blockchains at work.\r\n\r\n<strong>Making and Receiving Payments<\/strong>. When a client of our firm, that processes billions of international transactions a year, integrated Bitcoin as a payment option, they benefited from increased sales spurred by customers interested in using the cryptocurrency.\r\n\r\nThe client also found that it is possible to reduce fees. Fees associated with processing cryptocurrency transactions can be lower than third-party fees incurred by traditional transactions\u2014like payment processor and merchant services costs and charges for multi-currency transactions.\r\n\r\nNote use of the word \u201cpossible.\u201d This past December, Bitcoin\u2019s fee reached $34 per transaction. Soon after the credit card processor Stripe, among other firms, stopped accepting Bitcoin as payment. The transaction fees have declined some 97 percent since that peak. It is worth noting that other cryptocurrency options are available, such as Litecoin. And there is Ether, which is tied to particular blockchain platform.\r\n\r\n\u201cYour organization\u2019s choice of whether to accept a cryptocurrency for payment\u2014and which type\u2014will hinge on a number of factors specific to your business,\u201d advises Stuart Murray, project manager, WebINTENSIVE Software.\r\n\r\n<strong>Secure Recordkeeping and Accurate Analytics<\/strong>. Here are two datapoints with something in common:\r\n<ul>\r\n\t<li>About USD 461 billion counterfeit goods are imported worldwide, according to a report by the Organisation for Economic Co-operation and Development (OECD) and the EU\u2019s Intellectual Property Office. Fake goods range from footwear, perfumes, and handbags to machine parts and chemicals to bananas and strawberries.<\/li>\r\n\t<li>Before they make a purchase, 91 percent of U.S. consumers want transparency into the good\u2019s \u201csource of ingredients, manufacturing, handling, and shipping...\u201d according to a 2017 market study.<\/li>\r\n<\/ul>\r\nBoth situations point to a need for a clear, trustworthy record of a product\u2019s provenance. This need can be met by blockchains.\r\n\r\nFor instance, Forbes reported on Chinese ecommerce firms\u2019 use of blockchain, integrated with other technologies, to track products in an effort to counter counterfeiting.\r\n\r\nA digital identity is created for each product and coded in the first block of a new blockchain. Then, every time the product moves along its chain\u2014from farm to truck to warehouse to freight train to warehouse to cargo ship to warehouse to supermarket\u2014personnel scan an RFID or QR code to add that event to the growing chain. The product\u2019s entire trip is visible to all interested parties, all along the way. Counterfeiting now takes more than mimicking a product and forging packaging. Each product is backed by an entire digital history that is nearly impossible to fake.\r\n\r\nIt\u2019s important to note that data can be exported from blockchains to perform analytics and for visualization.\r\n\r\n\u201cSeeing a clear map of a product\u2019s movement in detail can provide many insights for process improvement,\u201d notes Marlon Feld, Ph.D., one of WebINTENSIVE Software\u2019s lead UX\/UI specialists. \u201cMore solid managerial decisions can be made when one is more confident about the accuracy of the data being presented.\u201d\r\n\r\n<strong>Smart Contracts<\/strong>. If you spend much time at all researching blockchains, you will soon come across mention of \u201csmart contracts.\u201d Most simply put, these are automated agreements for buying and selling goods or services. The terms of an agreement are embedded into lines of code and distributed on a blockchain.\r\n\r\nSmart contracts can be a useful means for supporting routine transactions at relatively low administrative cost. Various firms are pioneering use of this approach to reduce their customers\u2019 reliance on lawyers and banks. Use of smart contracts also can reduce the impact on cash flow of late payments or disputed payments and reduce the cost of collections and arbitration.\r\n\r\nA word of caution, however: platforms supporting smart contracts have been subject to bugs, hacks, and to human error, trapping currency in accounts without the ability to extract that currency. Sometimes the platforms reimburse their customers, sometimes they do not.\r\n\r\n<strong>Growing Numbers of Platforms<\/strong>. One positive trend: a number of firms are emerging that offer platforms and to speed and standardize blockchain development. \u201cThis will allow barriers to entry for midsized firms,\u201d Murray notes. Like players in this space, the platforms are experiencing some growing pains. For instance, human error last fall caused one to lock up several million dollars in a block\u2014and they have yet to devise a way to release those funds.\r\n\r\n \r\n<h3><strong>Assessing Your Specific Opportunities<\/strong><\/h3>\r\nInnovative uses of blockchains to solve business problems and to realize opportunities are coming up with great frequency.
