Blockchain Technology: Revolutionizing Trust and Decentralization
Blockchain technology is a revolutionary concept that has disrupted various industries and holds immense potential for the future. It emerged as the underlying technology for cryptocurrencies like Bitcoin but has since found applications in a wide range of fields, from finance to supply chain management and beyond. In this overview, we'll explore the fundamental concepts, key components, and diverse use cases of blockchain technology.
What is Blockchain?
At its core, a blockchain is a distributed and immutable ledger. It consists of a chain of blocks, each containing a set of transactions or data. These blocks are linked together using cryptographic hashes, creating a secure and tamper-resistant chain of information. Unlike traditional centralized systems, where a single authority controls the ledger, a blockchain operates on a decentralized network of computers, often referred to as nodes.
Key Components of Blockchain:
Decentralization: Blockchain networks are typically decentralized, meaning there is no single central authority. Instead, multiple nodes in the network maintain and validate the ledger independently.
Cryptography: Cryptographic techniques are used to secure data and control access. Each block contains a cryptographic hash of the previous block, forming a chain. Public and private keys are used to authenticate users and sign transactions.
Consensus Mechanisms: To validate and add new blocks to the chain, blockchain networks use consensus algorithms. Common consensus mechanisms include Proof of Work (PoW) and Proof of Stake (PoS).
Smart Contracts: Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automate processes and enforce rules without the need for intermediaries.
Tokens and Cryptocurrencies: Many blockchains have their native tokens or cryptocurrencies, often used as a medium of exchange within the network. Bitcoin (BTC) and Ethereum (ETH) are two well-known examples.
Types of Blockchains:
Public Blockchains: These are open to anyone and are maintained by a decentralized network of nodes. Bitcoin and Ethereum are examples of public blockchains.
Blockchain project: e-voting system based upon blockchain technologyHarender Singh
Most procedures are now centralized, licensed by the critical authority, controlled, measured, and monitored in an electronic voting system, which is a problem for a transparent voting process in and of itself.
Blockchain technology offers a decentralized node for online voting or electronic voting.
Distributed ledger technologies such as blockchain should be used to produce electronic voting system.
Vote: This is a complex digital voting solution that allows to conduct elections at any level it can be the elections of a country level: at government organizations plus it can be applied inside small organizations in general.

IOSR Journal of Computer Engineering (IOSR-JCE) is a double blind peer reviewed International Journal that provides rapid publication (within a month) of articles in all areas of computer engineering and its applications. The journal welcomes publications of high quality papers on theoretical developments and practical applications in computer technology. Original research papers, state-of-the-art reviews, and high quality technical notes are invited for publications.
Traditionally, in paper based election,voters cast their vote to select right candidate, where they simply put their vote in voting box and at the end of the voting day the votes are going to be count manually. This process was much time consuming as well as was erroneous. To overcome this drawback Electronic Voting Machine (EVM) was introduced. In EVM, Voter cast their vote by pressing the voting button which was on EVM. The Major advantage of EVM system is , the votes are counted automatically instead of manually. But the drawback of EVM machine was, the votes may get manipulated and was not secure. So to overcome all these drawbacks, research on biometric based voting system is going on. This Paper focuses on survey of different voting system using Fingerprint biometric through different algorithms and methods.

Adjusting OpenMP PageRank : SHORT REPORT / NOTESSubhajit Sahu
For massive graphs that fit in RAM, but not in GPU memory, it is possible to take
advantage of a shared memory system with multiple CPUs, each with multiple cores, to
accelerate pagerank computation. If the NUMA architecture of the system is properly taken
into account with good vertex partitioning, the speedup can be significant. To take steps in
this direction, experiments are conducted to implement pagerank in OpenMP using two
different approaches, uniform and hybrid. The uniform approach runs all primitives required
for pagerank in OpenMP mode (with multiple threads). On the other hand, the hybrid
approach runs certain primitives in sequential mode (i.e., sumAt, multiply).

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.
