“…The conception of bitcoin can be equated to internet, that has many technologies and applications. According to others, blockchain will certainly alter business in a similar way to how the internet did [2]. Blockchain can be defined as the structured data which is a type of shared database in the way that it stores data.…”

Various techniques are used to develop the Blockchain Technology. It is a technology which is designed in such a way that it is impossible to hack the system or hammer out the data stored in it [1]. It is one of the leading technologies in the current scenario. The goal of blockchain is to allow digital information to be recorded and distributed, but not edited. In this way, a blockchain is as the basis for absolute registry, or transactional records that cannot be changed, deleted, or otherwise disposed. Different domains are being adapting the blockchain technology which brings up the peer-to-peer connections and the cost of the middlemen is reduced. The technology uses authentication to secure the data and make it impossible to break than any legacy system [2].

Due to the pandemic, most of the personal transactions relating to finance, commerce and healthcare services have gone online making privacy preservation a critical requirement. Consequently, privacy has been made a critical parameter in Data Protection Regulations leading to the search for such a privacy compliant system which is also resilient to attacks. A detailed analysis of the Blockchain technology, which is becoming popular for secure applications in the finance sector, indicates that there are several challenges relating to user identity, transaction linkability, crypto-keys management, data privacy, usability, interoperability, and post- quantum compliance of privacy regulations which need to be resolved before its widespread adoption. Being a decentralised system, there is a need to analyse the vulnerability to attacks of each layer in the Blockchain architecture. This paper discusses the development flow of some of the privacy enhancement mechanisms like ZKPs, SMPC, Ring signatures, Mixing, Homomorphic Encryption and quantum resilient computing, bringing out their features and lacunae. There is a detailed discussion of the privacy mechanisms adopted by blockchain platforms like ZCash, Zerocoin, Hyperledger, Wanchain, Coin Party, Monero, Cryptomate, MixCoin, Coinshuffle, PICNIC and New Hope. Every platform has some limitation or the other and it is essential that researchers come out with mitigation steps for the existing mechanisms and come up with improved new Privacy Enhancement Techniques. One such architecture using PET has been proposed.
