Blockchain and cryptocurrency are phrases you’ll typically hear used collectively. Whereas they’re two distinctly completely different applied sciences, they’re additionally inherently intertwined with each other.

Basically a digitalized, decentralized, public ledger, blockchain is a formation of digital data, or blocks, saved throughout a community of computer systems making a database. When verifiable transactions happen, the data is saved in blocks, which, when full, are added to the chain.1 Cryptocurrency operates by way of the blockchain, because it too is a decentralized, digital system. Outlined as a digital or digital forex, crypto makes use of cryptography for safety and isn’t owned by any explicit authority, making it troublesome for governments to control.2

Bitcoin was the primary cryptocurrency, however the record has subsequently mushroomed to greater than 10,000.3 Blockchain know-how was, actually, popularized as the inspiration for Bitcoin.4 Regardless of many doubts and quite a lot of skepticism, each applied sciences have grow to be an essential a part of our financial techniques for the foreseeable future. A lot has modified and superior lately, however with the phrases so intently aligned, quite a lot of confusion nonetheless exists.

How blockchain and cryptocurrency work collectively

Relatively than being an non-obligatory know-how for cryptocurrency, blockchain is a foundational characteristic of it. In the end, the expansion and improvement of blockchain has been fuelled by cryptocurrencies, as crypto depends on its community to exist. However blockchain transcends cryptocurrency purposes. Not restricted to the monetary sector, the know-how provides a number of options which have already, and can proceed to, disrupt various markets within the years to return.5

The phrases have grow to be synonymous, maybe as a result of the primary blockchain was the database on which each and every bitcoin (the primary cryptocurrency) transaction was saved. When blockchain was first applied in 2009, it wasn’t often called such. It assumed its title due to the best way the transactions had been grouped into blocks of information, then chained collectively by the use of a mathematical perform that creates a hash code.6 The idea of a cryptographically secured chain of knowledge blocks had initially been envisaged in 1982, then developed within the early Nineties, nevertheless it was this revolutionary unique cryptocurrency that introduced the system to prominence.7

For these in search of a better give attention to cryptocurrency, the College of Cape City (UCT) provides the Blockchain and Digital Forex: The Way forward for Cash on-line quick course. This six-week on-line quick course will broaden your working information of blockchain and cryptocurrency, and reveal how crypto belongings are set to form the way forward for the monetary business.

Modern purposes of blockchain

You don’t must look far to provide you with an inventory of revolutionary methods through which blockchain know-how is being utilized. A variety of fields, together with healthcare, actual property, authorities, and music are discovering a use for blockchain’s highly effective, safe method of storing, verifying, and encrypting information.8 Listed below are seven extra purposes of blockchain know-how, a few of that are underscored by cryptocurrencies:


One of many fundamental companies of the monetary sector is to retailer cash and switch it from one entity to a different. This requires a reliable middleman, within the type of a financial institution. Blockchain is now successfully eliminating the necessity for such intermediaries by decentralizing transactions. By transferring the technique of transaction out of siloed, closed networks, blockchain helps to resolve a number of the challenges across the interoperability of disparate monetary techniques world wide.9

The power to trace all transactions will increase the transparency and safety of blockchain-based funds too. That is helpful each to the events of a transaction and to related regulators.10

Good contracts

Good contracts act as self-executing applications, triggered mechanically when predetermined situations are met, that facilitate the phrases of settlement between the vendor and purchaser straight. As they’re executed on a blockchain community, the transactions are trackable, clear, and irreversible.11 One of these automation can considerably enhance productiveness whereas slashing prices in enterprise. Put merely, it helps you change property, shares, authorized paperwork, or something of worth in a way that’s clear and freed from battle, whereas additionally avoiding the expense of a intermediary.12


Information saved on blockchain is rendered tamper-proof as a result of the community of nodes (the disparate computer systems on which the shared database is saved, and which validate transactions) can cross-reference to find the supply of a disputed change, so the know-how has numerous potential cybersecurity purposes. Storing data throughout a community of gadgets reduces the danger of a hacker exploiting a single level of vulnerability. Equally, decentralizing management of edge gadgets (which give an entry level into enterprise or service supplier core networks) and Web of Issues gadgets can render these gadgets safer in opposition to assaults.13

Well being data

A decentralized, safe, reliable blockchain system has clear purposes for the storage of healthcare data. Private well being data (PHR) accumulate information from sources together with medical facilities, gadgets, clinics, and pharmacies, and are primarily managed by sufferers. Digital well being data (EHR) are digital data of sufferers’ medical historical past, and are managed by docs.14

As sufferers handle PHRs, the validity of that data is typically doubted. Storing them on blockchains would guarantee they’re traceable, clear, unchangeable, auditable, and safe.

EHRs, alternatively, are usually saved in centralized legacy techniques, which is probably not interoperable between completely different healthcare amenities. Blockchain might provide an answer, with EHRs saved securely on a decentralized system that may be accessed – by each sufferers and healthcare staff – throughout techniques and organizations.15

Non-fungible tokens

NFTs, as they’re extra generally recognized, are tokens on blockchains, however they differ from cryptocurrencies in that they’re distinctive digital belongings.16 Technically, NFTs can signify possession of something, however they’re principally used to purchase and promote digital artwork. In lots of circumstances, this digital artwork already exists and is freely obtainable on the web for anybody to view, purchase, or obtain. What an NFT confers is possession of that artwork. Consider it because the distinction between proudly owning an unique portray and a print of it.17


Recording and storing high-value, high-volume items of information is inherent to the voting course of. This makes blockchain a super know-how for updating the voting system. As a result of all nodes on a blockchain should confirm any data entered onto it, folks might doubtlessly solid their votes on-line with out worry of fraud. It additionally creates better certainty for electoral officers, who can tally votes sure within the information that every is attributable to just one particular person.18

The way forward for cryptocurrencies and blockchain

The worldwide spend on blockchain is forecasted to succeed in $104.9 billion in 2028.19 With blockchain start-ups and conventional establishments more and more seizing the momentum this know-how offers, blockchain and cryptocurrencies are offering disruptions far past the monetary companies sector. The tempo of the know-how’s evolution exhibits no signal of slowing down.

Whereas there are those that stay unsure of cryptocurrency’s future, 2021 is seen by many as a breakthrough yr for his or her funding profile.20 Whether or not or not it’s a great long-term funding continues to be to be decided. Some see Bitcoin’s mounted provide as a purpose it’ll admire over time, whereas the broad ecosystem of decentralized purposes being developed on the Ethereum blockchain platform ought to improve its worth in the long term.21

To maintain abreast of the most recent blockchain developments, discover the MIT Sloan Faculty of Administration’s six-week Blockchain Applied sciences: Enterprise Innovation and Software on-line quick course. This on-line program examines the basic modifications that blockchain brings to enterprise and economics, and can equip you with the instruments to leverage blockchain know-how to drive innovation and effectivity in your group. Be taught extra about what you possibly can count on on the course right here.
