Blockchain is a distributed
ledger system with a growing list of records, called blocks, which are linked
using cryptography. Each block contains a cryptographic hash of the previous
block, a timestamp, and transaction data.
A blockchain is typically managed
by a peer-to-peer network collectively adhering to a protocol for inter-node
communication and validating new blocks. Due to high Byzantine fault tolerance,
the data, once recorded in any given block, cannot be altered retroactively
without alteration of all subsequent blocks, which requires consensus of the
network majority.
By storing data across its
peer-to-peer network, the blockchain provides decentralization and eliminates
central point of failure. Every node in a decentralized system has a copy of
the blockchain. No centralized "official" copy exists and no user is
"trusted" more than any other.
Blockchain platforms vary from
one another due to its implementation style. A good distributed ledger system
can be assessed by the following metrics:
Scalability
The most important feature
distinguishing different blockchain
platforms is the ability to scale. There are two major factors affecting
the scalability of a system.
A.
Firstly, blockchain is a growing list of
records which increases in size after every block. This in turns make
blockchain more scalable and it keeps on growing.
B.
Secondly, the transaction time, often
referred to as block-time, defines the frequency at which transactions are
added to the blockchain.
This depends
highly on the network organization and consensus. In consensus algorithms like
POW, validators solve mathematically complex problems, making the system take
up a certain amount of time to reach consensus, inherently limiting the
transaction speed. A low block-time can increase your transactions per second
but can also open up security threats like Race attacks or Finney attacks and
keeping it too high could result in reduced transaction speed.
Security
Blockchains are different from
classical distributed databases due to the security it offers, which is
paramount for any distributed system. They are designed from the ground up to
be secure. Malicious practices are taken for granted and care is taken to
minimize impact when a security vulnerability is discovered or on invalid user input.
The two important features adding
to security are immutability and decentralization.
A. Immutability
is partially achieved through novel methods of public-key cryptography, which
makes sure that any data on blockchain is tamperproof. Since the data is stored
across its peer-to-peer network, no centralized "official" copy
exists. This removes the central point of failure. Although data that currently
exists are secure, it is very much vulnerable when new data are added.
B. The
security of blockchain is achieved mostly through decentralized consensus. State transitions or data additions are
made only when majority of the network agrees on it. Due to the network effect,
as the network grows larger in size, the ability to counter bad actors also
increases. Thus based on the features, blockchain proves its worth and has been
used to create DAPP (Blockchain based decentralizedApps) for the betterment of the community and to provide benefit to the
society.
Using the above mentioned
features of next gen technology blockchain; Era Swap is coming up with a
blockchain based P2P decentralized marketplace for service providers and service seekers which empowers both
buyers and sellers. It tokenizes time as service and offers solution to various
elementary and still prevailing challenges of other traditional platforms or
marketplaces.
Be a part of this next gen global
decentralised marketplace to seek
maximum benefits as the marketplace will have several complementing components
to make it completely self-sustainable empowering the users with ease of trading
on Era Swap marketplace.
