Various distributed ledger technologies (DLTs), such as blockchain, have evolved significantly in recent years. These technologies provide a robust and effective solution for providing confidentiality, integrity, nonrepudiation, authentication, and transparency. While blockchain has many advantages, it has various limitations as well, such as complexity, low throughput, privacy, and so on. We discuss the issues that must be considered when deciding whether to use these technologies in a given case or not. We describe the operation of blockchain, application areas where blockchain is suitable, and those where it is not. We also discuss the applicability of other emerging DLTs, apart from blockchain technology, such as Hashgraph, Zcash, Nano coin, and IOTA. INTRODUCTIONAs the name suggests, a blockchain can be considered as a database where digital information (ie, "Blocks") is stored in a distributed network as a chain of blocks. Blockchain falls in the class of distributed ledger technologies (DLT) that allow a database to be used and maintained in a distributed manner. Blockchain provides a shared ledger of transactions 1 that can be read, verified and stored in the form of blocks, forming a chain-like structure. Depending on the size of the transaction, a block may store up to a few thousand transactions (eg, a single block in the bitcoin blockchain can store about 1 MB of data). The security and anonymity provided by blockchain relies on the use of public key based digital signatures, hash functions, and the distributed nature of the database. Participants in a blockchain are connected through a peer-to-peer (P2P) network and are independent of each other. 2 This architecture allows the sharing of resources, 3 avoids single point of failure, and reduces the likelihood of data tampering because the data is not stored or managed by specific nodes. [4][5][6] However, there are many challenges 7 that need to be resolved in the case of distributed networks. These challenges include accountability, confidentiality, integrity, nonrepudiation, and authentication, due to the absence of any central authority. Another major issue is trust because there is no central authority that can resolve any ambiguities or disagreements that may occur. Blockchain resolves all these issues. Confidentiality and authentication are ensured using two-way encryption, that is, by encrypting the data first by the sender's private key and then by the receiver's public key. To decrypt it, first the receiver's private key is used and then the sender's public key. Consequently, data remains confidential, integrity is achieved and because the data can be obtained using sender's public key, it acts as a digital signature that authenticates the data and eliminates the possibility of nonrepudiation. Trust is obtained by introducing a consensus Trans Emerging Tel Tech.

In the face of escalating crime rates accompanying rapid urbanization, traditional criminal record systems face challenges of tampering and inefficiency. The Paper proposes a blockchain-based solution, leveraging the decentralization and immutability of blockchain to create a secure and transparent network for legal records. By utilizing peer-to-peer networks, this system ensures easy accessibility while safeguarding data integrity through the immutability feature of blockchain. The decentralized nature of the blockchain reduces corruption risks, allowing third parties to monitor tamperproof transactions and promoting objectivity in criminal record management. The blockchain-based approach not only enhances transparency and accountability in criminal record keeping but also facilitates timely access to authentic records for law enforcement authorities. The Paper aims to revolutionize record management, making it more efficient, secure, and conducive to effective law enforcement in evolving urban environments.

Federated clouds are interconnected cooperative cloud infrastructures offering vast hosting capabilities, smooth workload migration and enhanced reliability. However, recent devastating attacks on such clouds have shown that such features come with serious security challenges. The oblivious heterogeneous construction, management, and policies employed in federated clouds open the door for attackers to induce conflicts to facilitate pervasive coordinated attacks. In this paper, we present a novel proactive defense that aims to increase attacker uncertainty and complicate target tracking, a critical step for successful coordinated attacks. The presented systemic approach acts as a VM management platform with an intrinsic multidimensional hierarchical attack representation model (HARM) guiding a dynamic, self and situation-aware VM live-migration for moving-target defense (MtD). The proposed system managed to achieve the proposed goals in a resource-, energy-, and cost-efficient manner.
