Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, to maintain a secure and decentralized record of transactions. Let's start with some quick definitions.
blockchainis the technology that allows the existence of cryptocurrencies (among other things).
bitcoinis the name of the best-known cryptocurrency, the one for which blockchain technology was invented.
A cryptocurrency is a medium of exchange, like the US dollar, but it is digital and uses encryption techniques to control the creation of monetary units and verify the transfer of funds. Even crypto skeptics see the value of blockchain technology. The real gem is blockchain, says Chris Chen, CFP of Insight Financial Strategists in Newton, Massachusetts. He believes that blockchain is likely to have much more staying power than popular cryptocurrencies like Bitcoin, which he calls a flash in the pan.
That all sounds great, but what exactly does it mean? Here's what you need to know about blockchain and what a blockchain revolution might look like. Bitcoin seems to be here to stay, even if the price has recently plummeted. An entire industry has been created around the possession and trading of digital assets like this. But attempts to create more complex applications using blockchain are hampered by the underlying technology.
Blockchains offer an immutable record of data without relying on a central authority that is critical to the enthusiasm behind the technology. But the crypto machinery behind blockchains is notoriously slow. Early platforms, such as Ethereum, which gave rise to the ICO frenzy, are too slow to handle most trading applications. For that reason, “decentralized projects represent a small part of corporate blockchain efforts, perhaps 3 percent,” says Apolline Blandin, a researcher at the Cambridge Centre for Alternative Finance.
Financial institutions are exploring how they could use blockchain technology to change everything from clearing and settlement to insurance. Retain core entities that control data, eliminating core innovation from blockchains. The technology at the heart of bitcoin and other virtual currencies, blockchain is an open and distributed ledger that can record transactions between two parties efficiently and verifiably and permanently. Still, blockchain technology has the potential to result in a radically different competitive future for the financial services industry.
Because blockchain and Bitcoin are so inextricably linked, it took a long time for people to realize that blockchain actually has much broader applications beyond cryptocurrency networks. By inherent design, the data on a blockchain cannot be modified, making it a legitimate disruptor for industries such as payments, cybersecurity, and healthcare. But, like the adoption of more Internet technologies, blockchain adoption will require extensive coordination and will take years. In fact, virtually everyone has heard the claim that blockchain will revolutionize business and redefine companies and economies.
Financial services companies, for example, are finding that the private blockchain networks they have created with a limited number of trusted counterparties can significantly reduce transaction costs. If that happens, the economy will again undergo radical change, as new sources of influence and control based on blockchain emerge. But he recognizes that privacy issues, as well as local rules and legacy computer systems, mean that blockchain isn't always a good fit for government. .
