What is Blockchain Technology? - CORRECT ANSWER-From a cruising
altitude, a blockchain might not look that different from other decentralized digital
systems - like, say, Wikipedia.
With a blockchain, many people can write entries into a record of information, and
a community of users can control how the record of information is amended and
updated. Likewise, Wikipedia entries are not the product of a single publisher. No
one person controls the information.
Descending to ground level, however, the differences that make blockchain
technology unique become more clear. While both run on distributed networks
(the internet), Wikipedia is built into the World Wide Web using a client-server
network model.
, A user (client) with permissions associated with its account is able to change
Wikipedia entries stored on a centralized server.
Whenever a user accesses the Wikipedia page, they will get the updated version of
the "master copy" of the Wikipedia entry. Control of the database remains with
Wikipedia administrators allowing for access and permissions to be maintained by
a central authority.
(Maria Kuznetsov)
Wikipedia's digital backbone is similar to the highly protected and centralized
databases that governments, banks or insurance companies keep today. Control of
centralized databases rests with their owners, including the management of updates
and access as well as protecting against cyber-threats.
The distributed database created by blockchain technology has a fundamentally
different backbone. While Wikipedia's "master copy" is edited on a server and all
users see the new version, in the case of a blockchain, every node in the network is
coming to the same conclusion, each updating the record independently, with the
most popular record becoming the de facto official record in lieu of there being a
master copy.
On a blockchain, transactions are broadcast, and every node
How Does Blockchain Technology Work? - CORRECT ANSWER-here are three
principal technologies that combine to create a blockchain. None of them are new.
Rather, it is their orchestration and application that is new.
