The way that this system could work would see a patient essentially own their health records. They can then grant or deny access to doctors or researchers, preventing unauthorised access, third party resale and tampering. The problem comes when you consider the scalability of something like blockchain into an already complicated and messy system, and the privacy of the stored data. A potential solution to this could be the Enigma Project, an off-chain network serving as an extension to conventional blockchain platforms.
By processing data off-network, the Enigma network can process-intensive computations that remain publicly verifiable on the blockchain.
The computer games industry relies entirely on data transference. With the advent of gaming systems such as loot boxes and in-game currencies, it is becoming a complicated minefield of new transactions and data transfers. Blockchain can be applied in a variety of ways to the industry, such as through payment methods for buying and selling games, as well as managing in-game currency accounts. A game such as Fortnite will adorn winning players with a variety of rewards such as currency, gear, cosmetics and unlockable items. Blockchain technology could be applied to this integral purchasing framework, potentially adding enhanced transparency and security for players, making cheating more difficult, and allowing inter-game trading and transfers.
Games giant Ubisoft and the Azarus game challenge network have been using blockchain to allow gamers and streamers to engage in challenges using the EOSIO blockchain protocol. The platform allows users to create their own rules and challenges using the blockchain platform, maximising transparency and fairness.
A likely avenue for blockchain in the industry, however, is in gambling games. Currently, the lack of transparency, regulatory controls, oversight and the overwhelming power of gambling game companies can allow them to easily take advantage of vulnerable players. Blockchain can add a level of safety and certainty as game results running on blockchain are determined as intended and without interference. Companies such as Forte are already looking at the prospects of using blockchain. Blockchain potentially offers the oil and gas industry a huge boost in the entire transaction, price, trading and payment ecosystem.
Supply chain networks are the lifeblood of the industry, and blockchain offers a way to drive efficiency, prevent fraud and help with cost effectiveness.
It has massive applications for the shipping side of oil and gas production. Shipping vast quantities of supplies is a complex process that requires many different parties to participate, signing documents and ensuring the ships are following the correct routes.
Blockchain can streamline this process by creating a secure data exchange on the system and a tamper-proof repository for the documents and shipping events. Using this system could significantly reduce delays in shipping and fraud, saving billions of dollars annually across the entire supply chain. Subscribe to News. Tell the world!

Similar to a written record, it has chapters—or blocks—of information, each added sequentially over time. While blockchain employs a variety of modern technology and security steps absent in a written text, its essence is similar to the first records and contracts etched by humans.
However, the blockchain fundamentally differs from all previous records, including more recent digital versions stored on PCs and across the internet, in two distinct ways. First, the blockchain is a shared record. Prior records were centrally controlled and updated, whether written documents by individuals, or digital files owned by database administrators. In every case, a centralized authority governed the record.
By contrast, the blockchain exists in perfectly replicate form across multiple locations. In other words, it is a distributed record. No single participant owns the blockchain or dictates additions to it.
Rather, updates are a function of consensus amongst participants. Illustrating this distinction with a concrete example, Coindesk described Wikipedia , a record that resides on a centralized database, and for which, changes are only made by the database administrator. If the blockchain supplanted the digital backbone of Wikipedia, its database would reside on the computer of every curator, and changes would occur simultaneously across each database instance, as a function of a consensus process.
Second, the blockchain is immutable.
It stores a history of itself back to the first entry, known as the genesis block. The identity of each new entry is created, in part, from the identity of the previous entry. Because every individual block is inextricably linked to all that precede it, changing its content or identity is essentially impossible. The upshot of blockchain immutability is its unprecedented security—a tamper-proof record, impervious to assaults by bad actors.
Contextualizing blockchain within the enterprise, it is helpful to view it as a data store, according to Toptal blockchain engineering expert, Dan Napierski. Viewed as a data store, blockchain presents trade-offs versus traditional business databases. As with all tools, it must be applied to the right job. According to Napierski:. They are often designed for efficient querying across the entire data set. Although tools exist to search for data within the blockchain, it is not designed for fast queries. Further, as an append-only database , blocks cannot be changed once committed to the blockchain.
The blockchain only changes by the addition of new blocks. Accordingly, blockchain is not designed to perform some of the standard operations of a traditional database, such as updating and deleting information. Elaborating on the potential for corporate applications, Napierski noted two distinct advantages of a blockchain database:.
No third parties. Blockchain eliminates the need for an intermediary third party, such as a bank. Both transacting parties can trust that information added to the blockchain can not, and will not be changed. Large corporations could directly interact with each other, writing their own contracts with no need to involve third parties, or any other intermediary to assert correctness.
Two types of blockchain: public and permissioned There are two types of blockchain: public and permissioned. Blockchain can handle event data and document workflow by enabling trustless and transparent monitoring of transactions. Unless specifically noted, all references to the permissioned blockchain will assume the semi-private version. License Term. Complex confidentiality and reporting requirements make healthcare a proverbial minefield. Please whitelist Venafi. While both structures are theoretically relevant to the enterprise, the semi-private also known as federated or consortium blockchain holds more practical potential, as most companies transact with multiple organizations.
Faster consensus. Blockchain allows participants to reach consensus, or settle the transaction quickly. Multi-day processes channeled through intermediaries are reduced to minutes. So, for shared records such as contracts, the blockchain fundamentally transforms ownership, transparency, security and consequently, the value of the records and the process they govern.
In the context of a shared record or contract, blockchain reframes the concept of trust. Succinctly captured by The Economist , the blockchain lets people or companies who have no particular confidence in each other collaborate without having to go through a neutral central authority. Simply put, it is a machine for creating trust. There are two types of blockchain: public and permissioned. Underlying popular cryptocurrencies such as bitcoin and ethereum, a public blockchain is open to anyone and all participants are anonymous.
Anyone can download the blockchain for example, the blockchain underlying bitcoin was about GB at the end of , read all historical transactions, use their computer to validate new transactions, and add new transactions to the network without ever disclosing their identity. However, within the context of enterprise applications, which focus on a finite cast of participants, public blockchains are not relevant.
Contrary to public blockchains, permissioned blockchains are open to a limited number of participants whose identities are all known. There are two forms of permissioned blockchain: private and semi-private.
Accessibility beyond a single organization distinguishes these two structures; the private blockchain operates within, while the semi-private operates between organizations. While both structures are theoretically relevant to the enterprise, the semi-private also known as federated or consortium blockchain holds more practical potential, as most companies transact with multiple organizations. Unless specifically noted, all references to the permissioned blockchain will assume the semi-private version. Unlike the public blockchain, which has no defined leadership, the permissioned blockchain designates several participating parties with the authority to control the consensus process, the mechanism by which transactions are verified.
Evidence of commercial potential for permissioned blockchain networks, several significant consortia, such as Hyperledger , Enterprise Ethereum Alliance and R3 , are emerging to equip participating members with robust technology.
