Does Blockchain Technology Prevent from Data Tampering?
Introduction
This essay aims to provide the discussion around the analysis of the potential of
blockchain to prevent data tampering. The analysis of the social context and the impacts of
the blockchain is briefly discussed in this essay. A comprehensive discussion of the risks and
the uncertainties that are associated with this question is briefly discussed and elaborated.
Lastly, an appropriate conclusion is offered for the essay.
Problem statement
Does Blockchain Technology Prevent from Data Tampering?
There has been several responses related to the discussion of the impact of blockchain
in data tampering and the effectiveness of blockchain to prevent data tampering. It has been
earlier discovered that this technology is particularly effective in implementation for data
tampering prevention (Swan 2015).
Discussion
Formation of blockchain
Blockchain is the growing list of the records that are also referred as blocks that are
linked with the help of cryptography. Each of the block comprises of one cryptographic hash
of previous block, transaction data or the timestamp. The major elements are the digital keys
of the users due to the fact that they permit the ownership features. The users in the
blockchain are provided with two keys that are private and public (Yli-Huumo et al. 2016).
The private key is utilised for mathematically deriving the public key that is then transformed
with the hash function for producing the address that could be viewed by other people. The

mining process is an important aspect that powers the decentralised blockchain. The miners
are essentially interconnected and independent nodes that utilise the computing power for the
verification of the transactions and then add them to public ledger (Cachin 2016). Without the
influence of the miners, the decentralised blockchain network is not possible. The smart
contracts are commonly based on the blockchain and these are the proposed contracts that
could be completely or partially enforced or executed without any human interaction. The
smart contracts are the self-executing code on blockchain structure that allows the straight
through processing that means that none manual intervention is needed for the execution of
the transactions. The major role of the smart contracts is the automated escrow. The
Distributed ledger technology is the digital system to record the transaction of the assets
where the details of the transactions are recorded in several places at similar time. This
technology is majorly used in the blockchain that groups the transactions into the blocks that
are combined together and then it is broadcasted to the nodes in network of the blockchain
(Azaria et al. 2016). The consensus mechanism is the fault tolerant mechanism that is utilised
in the blockchain and the computer systems for achieving the required agreements on any
single data value or any single state of the network between the distributed processes or the
multi-agent systems. The Proof Of Work or POW is the common consensus algorithm that is
utilised by the popular cryptocurrency network like the Litecoin and Bitcoin (Pilkington
2016).
Impacts of blockchain
Blockchain is the distributed ledger technology that makes the bitcoin possible by
providing the record of each of the transaction and then proving who possesses the material at
a moment. The societal implications of the blockchain technology is presently considered as
colossal. (Kosba et al. 2016).
