Blockchain has potential to make a huge impact. Learn about fascinating blockchain trends that are emerging in 2019 and beyond. Blockchain technology was invented to safeguard the cryptocurrency infrastructure (e.g. Bitcoin), enabling secure financial transactions without the need for a bank or a middleman. But blockchain’s ledger technology is now expanding beyond digital currency and financial services, offering great potential to improve upon many areas of our lives. As blockchain matures and becomes more accessible, companies across various industries are finding compelling use cases for blockchain to make businesses processes more efficient. For example, banks can now reduce infrastructure cost by 30% throughblockchain solutions. This is achieved by encrypting millions of storage points, none of which contain a full name or an account number. While blockchain is currently only being used by 0.5% of the global population, emerging trends are making it more scalable. It is anticipated that 80% of the population will be using blockchain technology in some capacity within 10 years. Because the HR department is charged with managing so much sensitive data, blockchain technology will be integrated directly into the HR function through a multitude of possible use cases—adding transparency and trust to an organization’s operations. The evolution of blockchain will also mean companies need a workforce with new skills, so HR will be kept busy with recruitment and talent management. The following blockchain trends are lifting ledger technology from the obscurity of cryptocurrency and making blockchain part of the mainstream conversation. 1. More potential real-world uses on the horizon will raise the visibility of blockchain. While cryptocurrency and financial institutions are the pioneers of blockchain, it is important to note that tokenization and securing payments are just precursors to many potential real-world uses for ledger technology. Every transaction on the blockchain is on public record and its enhanced security makes it a virtually incorruptible platform. Because no central party will ever be in control of all of the record keeping, blockchain can be used to mitigate financial, political and institutional corruption in corporations and governments, alike. Blockchain may also be able to improve the political sphere in terms of voting systems. Because records cannot be altered in any way, blockchain is ideal for voter registration, identification and vote tallying. Election corruption and voter fraud would be eliminated, ensuring a more accurate, fair electoral process. The general public will also be drawn to blockchain’s ability to eliminate transactions fees. Owing to decentralization, sending and receiving money can be expedited and enhanced. This has implications for automated legal procedures, customs payments, ownership transfers and business transactions—allowing widespread disintermediation across industries and economies. Another mainstream use could be in public records of ownership, citizenship and identity. Even in the thriving digital era, these records are stored in centralized databases for security. However, this exposes them to tampering because of the intermediaries it engages. Blockchain opens up the possibility of a decentralized, public, fixed and consensus-driven ledger of records that could nullify the need for intermediaries. A groundbreaking example of this is Estonia’s E-Citizenship Program, which stores citizens’ information on a blockchain. The application of blockchain can also be extended to include organizational information for the HR department, where one day a company can maintain one identity stored in a master Blockchain. This could be safely accessed by all stakeholders including vendors, employees, customers and tax authorities. 2. Blockchain as a Service (BaaS) will facilitate business adoption. A Blockchain-as-a-Service (BAAS) platform is a full-service cloud-based solution that connects developers, entrepreneurs and enterprises on one platform. On the BaaS, stakeholders can develop, test and deploy blockchain applications and smart contracts. Moreover, the BaaS platform provides all the necessary infrastructure and operational support, ensuring that the applications run efficiently. BaaS providers include major companies like Microsoft, IBM, SAP, Amazon, Oracle, and Hewlett Packard. These providers are nurturing blockchain adoption among business because the platforms enable companies to engage blockchain projects without having to spend anywhere near as much money as they would developing customized blockchain solutions independently. As more businesses look for convenient and cost-effective ways to implement blockchain technology, BaaS collections will most likely continue to expand. Keeping an eye on the emerging BaaS space can help an HR department choose the right provider for (future) company needs. 3. Blockchain will be less associated with cryptocurrency & possibly rebranded. Blockchain was born and bred to protect Bitcoin’s infrastructure— but now ledger technology is leaving the cryptocurrency nest to explore more business endeavors. Blockchain’s association with the volatile cryptocurrency market has potentially diluted its reputation. There are still negative connotations with cryptocurrencies, including wild price swings and the perceived link to people buying illegal items from the dark web. But mainstream industries, such as manufacturing and retail, are proving the power of blockchain to improve supply chain management and ownership tracking. To break out of the cryptocurrency pigeonhole, it is expected that the blockchain industry will make a concerted effort to establish an identity that’s separate from cryptocurrency—and better educate the business sphere on the advantages it offers, beyond financial transactions. To take the rebrand a step further, research from Forrester suggests that it might be beneficial for the blockchain industry to drop the name blockchain and replace it with distributed ledger technology (DLT). 4. Blockchain enabled Internet of Things (IoT) systems. Gartner predicts that the number of installed Internet of Thing (IoT) will exceed 20 billion by 2020. As HR departments integrate more IoT into companies, there is growing concern because these connected devices often open the door for hackers. The same vigilance applied to computers is sometimes overlooked when ensuring the security of the IoT infrastructure. As a company’s digital ecosystem expands to include more IoT devices, they can be left vulnerable to hacks. Blockchain offers strong protections against data tampering by locking access to IoT devices and shutting down compromised devices within the IoT infrastructure if a security event is suspected. Blockchain serves to effectively decentralize data, which provides a safety net from hacks and fraud. In the digital age, data is fast becoming the most prized asset a company has. If you store all your jewelry, cash and other valuables in one location of your home, what happens if a burglar enters your home and is able to find this location? Because it spreads data across a large network of computer storage spaces, storing records on a blockchain network is like placing your most valuable digital assets across a multitude of places to mitigate your risk of being severely impacted or wiped out by a hacking event. One of the first blockchain IoT-specific platforms is IOTA, which provides transaction settlements and data transfer layering for IoT devices. IOTA has launched its Tangle platform, which developers describe as “going beyond blockchain.” This serves as a blockless, cryptographic, decentralized network, where, rather than outsourcing network verification to data miners, users verify transactions of other users. Such IoT platforms promote greater scalability while also eliminating the need to pay transaction fees to data miners. These are both essential factors in a practical IoT network, which could potentially require the processing of billions of micro-transactions between devices daily. 5. Hybrid blockchains are promising the best of public & private networks. As blockchain rapidly comes of age, there are generally two communities that have been established. On one side of the tracks, there is a large community supporting public blockchains and arguing for decentralization. On the other side, there is a more niche community—comprised mostly of businesses and their clients—pushing for private blockchains operated by a single entity that also grants permissions to users. Traditional blockchains (e.g. Bitcoin and Ethereum) are public and completely open, meaning anyone can join the consensus protocol and participate in maintaining the shared ledger. Users often join public blockchains because, apart from operating in a decentralized system, they can offer incentives for mining or staking. But public blockchain have limitations, including visibility. Data is completely transparent so anyone can access it, presenting a privacy concern for many uses. In some blockchain use cases, data would need to be restricted and a public blockchain cannot do this. Public blockchains also demand high computational power and consume large amounts of electricity. There are also scalability concerns for public blockchains because the consensus protocol places limits on speed and the number of transactions it can process. Private blockchains operate similarly to public blockchains with an important exception: they are not open to everyone and require an invitation to join. These blockchains are also permissioned networks and can be customized to interact with certain users differently than the general users. Unlike in the public blockchain, provisions can be outlined to determine who is allowed to participate in the network and what specific transactions they are authorized to conduct. While private blockchains address some data security concerns, the main drawback is that they are not as decentralized as the public blockchains. To build a bridge, hybrid blockchains are being developed to offer decentralized platforms that can restrict visibility of some information on the network. In particular, this model is appealing to regulated markets because it offers the benefits of public and private blockchains in one network. Through a hybrid blockchain solution, a company can conduct transactions from certain short-term partners and vendors on the public blockchain side. Since the transaction timeline of these partners is shorter, public blockchain is an ideal solution. It would not require the level of trust needed with a private blockchain. The private side of a hybrid blockchain solution can be used to conduct transactions with long term partners. It would operate with a classic permissioned setup, where authorized parties can view, transact and make changes based on permissions they are given. This private network is fast, scalable and secure. However, adding more parties and establishing their trust takes longer than on a public blockchain so it would only be reserved for transactions with designated users. 6. Sidechains are improving scalability. For all their power and complexity, blockchains face challenges in scalability and speed. These limit some applications of the relatively new technology. One solution that seeks to improve blockchain efficiency and scalability is the sidechain. As its name indicates, a sidechain is a type of blockchain that accompanies a master chain. In the relationship, the master chain is the parent chain and the sidechain is the child chain. In order to trade assets from the master chain for assets from the sidechain, the user would first need to send their assets on the master chain to a certain location. This would effectively place a lock on the assets for the time being. After the transaction completes, the sidechain would receive a confirmation and release a designated amount of the sidechain to the user—equivalent to the amount of assets locked up by the main chain times the exchange rate. This also works in reverse to trade assets from the sidechain to the master chain. As sidechains store data and process transactions, they help to uphold the integrity of the master blockchain while making it smaller and more agile. When implemented correctly, sidechains relieve the master chain of some of the work, helping to solve the inherent scaling problem associated with blockchain solutions. Sidechains have practical applications for stock exchanges. 7. Artificial intelligence (AI) & blockchain are teaming up. While both AI and blockchain involve high levels of distinct technical complexity, there is potential for these two technologies to team up and score major technological victories in the next five to ten years. The first change win might be in optimizing data management. Blockchain currently relies on hashing algorithms for data mining and these operate in a brute force style, meaning the algorithm inputs all possible sequences of characters until it finds the one that matches with the verification process. This demands extra steps, lags and effort. AI can step in to offer an intelligent data mining system that streamlines the entire process and cuts down total costs exponentially. This streamlining also has implications for improved energy consumption for blockchains. AI can infuse natural language processing, image recognition and multi-dimensional real-time data transformation capabilities into a blockchain’s peer-to-peer linking. This allows data miners to turn a large-scale system into a series of micro-economic environments. In turn, this can optimize data transactions in a secure and effective manner. Most importantly, machine learning intelligence adds flexibility to the process. On the flipside, blockchain’s data decentralization technology can help AI step up its game in creating better machine learning models. Introducing secure data sharing across systems, which have traditionally stored and operated data in an isolated manner, introduces higher quality data. Richer data means better models, better predictions and better insights. Data decentralization will offer companies of all sizes access to analytics and insights they could not possibly generate from an individual data source. When AI’s deep learning algorithms gain access to multiple data points from multiple data pools that have been standardized by blockchain, the competitive advantage of an AI technology will no longer be about finding the data itself. Nor will it be about having the resources and funds to gather the most data. Instead the focus will be on writing the most innovative algorithms. This evolution ushers in a new era of scalability for deep learning where AI finds itself in new marketplaces, opens doors for smaller players and gains trust with the public at large. The future looks bright for blockchain and it will likely innovate business processes in many industries, including human resources. However, its widespread adoption and full potential have yet to be seen. The next phase of development for blockchain will be in addressing scalability and accessibility challenges, which will pave the way for more applications and varied use cases across more industries. Amid the rapidly evolving digital landscape, one thing is clear: blockchain is in a state of metamorphosis with many disruptive trends on the horizon. For HR professionals, it is important to keep an eye out on how this nascent technology is impacting various industries and making its way to the world of work.
