If the internet was the breakout consumer technology of the first decade of the new millennium, the second decade arguably belongs to blockchain technology. It’s been just over a decade since Satoshi Nakamoto, who can be considered as the father of blockchain, introduced us to Bitcoin through his eponymous whitepaper. And while Bitcoin grew mainstream, thousands of other cryptocurrencies popped up all around the world, each having its niche use cases. But cryptocurrency is just one of the applications of comprehensive blockchain technology, a mere tip of the iceberg. Over time, as adoption grew and people began to see blockchain as a trusted approach, more and more avenues opened up. Blockchain technology was used in implementing smart contracts, supply chain and logistics, IoT, cross-border payments, fraud detection, securing medical records, and more.
What is the real concept of Blockchain?
Blockchain
seems complicated, and it definitely can be, but its core concept is quite
simple. A blockchain is a type of database. To be able to understand blockchain
helps to first understand what a database is.
A database
is a collection of information that is stored electronically on a computer
system. Information, or data, in databases is typically structured in table
format to allow for easier searching and filtering for specific information.
What is the difference between someone using a spreadsheet to store information
rather than a database?
Spreadsheets
are designed for one person, or a small group of people, to store and access
limited amounts of information. In contrast, a database is designed to house
significantly larger amounts of information that can be accessed, filtered, and
manipulated quickly and easily by any number of users at once.
Large
databases achieve this by housing data on servers that are made of powerful
computers. These servers can sometimes be built using hundreds or thousands of
computers in order to have the computational power and storage capacity
necessary for many users to access the database simultaneously. While a
spreadsheet or database may be accessible to any number of people, it is often
owned by a business and managed by an appointed individual that has complete
control over how it works and the data within it.
How Blockchains Elevate the Level of
Trust in the System?
It wouldn’t
be wrong to say that mankind’s biggest invention ever is coming up with the
concept of credit. This single human construct has accelerated innovation and
expedited our transformation from clueless cavemen to world-conquering humans.
And credit, or any other human interaction for that matter, is based on the
concept of trust.
What makes
the emergence of blockchain a watershed moment for us is that it showed the
world that unbreakable, mathematical algorithms are more trustworthy at keeping
records than error-prone humans or morally sketchy institutions. Look no
further than the myriad multi-crore banking scams that have eroded the trust in
centralized institutions.
We see tremendous potential for blockchain in emerging economies. Financial services and insurance in the United States are sophisticated and offer adequate comfort, convenience, and safety measures to service and protect retail consumers.1 This trust in centralized parties, however, is not a universal reality. Thus, in emerging economies, the institutional trust required for the provisioning of financial services and the breadth of coverage of newly growing economies can benefit from decentralized technologies.
Blockchain
is a “trustless” ledger technology that minimizes central authority control. It
enables peer-to-peer transactions with a minimized need for costly “trusted”
third-party assurance, bookkeeping, or facility. Blockchains also provide an
immutable history of transactions, which can be leveraged as a bona fide
identity for individuals and families without access to traditional,
state-sanctioned identities. In this way, blockchain protects against the
failure of centralized institutions (relevant in many emerging markets
experiencing hyperinflation or broken financial sectors) and enables services
for demographics that are often left out of the traditional financial sector
due to identity and credit barriers (some 1.7 billion adults across the world).
