Title: Future will be full of Dapps - Scala blockchain


1
Future will be full of Dapps? ?Scala blockchain
2
The birth of decentralized applications
  • A decentralized application is the one which
    runs by getting data from the network of
    computers instead of a single data server. So
    that the single point of failure is avoided.
  • If the computer data is not available, the
    application gets the data it wants from any other
    node of the network. Dapps are blockchain enabled
    applications or websites.

Here are some of the noticeable common features
of Dapps
Decentralized All records of the applications
operation has to be stored on a public and
decentralized blockchain to avoid the pitfalls of
centralization. Open source It should be
governed by the autonomy and all the changes must
be decided by the consensus or a majority of its
users. This code base should be available for
scrutiny.

  • Protocol
  • The application community must agree on a
    cryptographic algorithm to show proof of value.
  • For example, bitcoin uses proof of work and
    ethereum is currently using proof of work with
    plans for a hybrid PoW/PoS (Proof of Stake) in
    the future.
  • If we adhere to the above definition, the first
    Dapp was in fact bitcoin itself.
  • Bitcoin is an implemented blockchain solution
    which arose from problems revolving around
    centralization and censorship.
  • Bitcoin is a self sustaining public ledger
    which allows efficient transactions without
    intermediaries and centralized authorities.

5
Cryptocurrencies and bitcoin are based on a
technology called blockchain. Blockchain is
basically a continuous growing list of blocks
which contains data that is distributed among a
network of computers. It directs peer to peer
connection without the involvement of any central
authority or middleman.

Lets see what is smart contract along with an
example
A smart contract is a piece of computer program
which runs if certain conditions are met. For
instance In a football match, you bet 10 that
the Team A would win and your friend bets on
Team B. Both can place a bets by writing a
smart contract.
Just imagine the same scenario without smart
contract Both give 10 to a third person and
he will decide whom to give it when any one of
the team wins. In this situation, there is a
possibility that he might run away with your
money.

  •   You and your friend trust each other and when
    the match is over with a winning side, the losing
    one should pay the winner 10. But it is still
    not easy.
  • You both can write the legal contracts for this
    transaction since the process is convoluted and
    this is not the absolute choice because the
    amount involved in this transaction is very
    little.
  • It has a perfect solution for this problem. By
    using the smart contracts, we can write the set
    of conditions that send the winner the payout
    automatically without the need of anyone. You and
    your friend just need to keep 10 in your
    respective wallets.

  • Smart contract is more than that and ethereum
    is specifically created to write the smart
    contracts for the usage in decentralized
    applications.
  • The web was intended to be a decentralized
    platform but it no longer is. Tech giants store
    and process the user data in a centralized data
    centers.
  • The major issue with centralized data centres
    is, the users data can be misused easily since
    it is controlled by a central agency.
  • People are really concerned about the privacy
    and they need a decentralized ecosystem. With the
    growing interests and usage in decentralized
    apps, it should not be ignored.

A Decentralized Dapps Future Awaits
  • The inevitable onslaught of blockchain adoption
    render numerous practices obsolete.
  • It may be a bold and distinct conjecture where
    the services such as banking will be made
    redundant as the world learns to operate and
    finance itself by self sustaining, trust less and
    decentralized networks.
  • There are corporations which are hurrying to
    secure the place in the blockchain movement is
    only a testament to that.

10
  • With a leap of faith, blockchain is the next
    step forward and toward a world unified by shared
    data.
  • Scalablockchain is a blockchain development
    company which specializes in developing Dapps for
    business as well as consultation.
