These blocks are impervious to any change and can effective e-voting mechanism by leveraging blockchain's be verified indefinitely. To make any modifications within capabilities, such as cryptographic foundations and blocks, more than half of the network's users must agree. transparency. However, there are still barriers to wider adoption of such systems, especially in terms of strengthening The 'Genesis block' or 'Block 0' is the first block in a their resilience. The old traditional technique, which relies on blockchain. The genesis block is frequently hardcoded into a centralised infrastructure, has security and transparency software; it is unique in that it contains no references to issues. Some of the issues with traditional election systems prior blocks ('Genesis Block') [2]. Once the genesis block has include a lack of complete control over an organization's been initialised ‘Block 1’ is created and when completed, it is database and system, as well as the possibility of tampering attached to the genesis block. Each block comprises a with the database. Blockchain technology is based on a transaction data section, which is followed by hashing copies decentralized system, with multiple users accessing the same of each transaction and then the hashes are paired and database. Blockchain technology creates a network structure hashed again, this continues until a single hash remains; also data with built-in security features. It is built on the known as a Merkle root. In Blockchain 1.0, a block is a data encryption, decentralization, and consensus principles, which structure to store transaction records. It consists of two ensure transaction confidence.

The following fields are found in the block header: Key words: Blockchain, cryptography, decentralization. • Block Version: defines the block validity rules.

I. INTRODUCTION
• Merkle Tree Root Hash: maintains the hash value of all transactions in the block.
After the advent and widespread acceptance of Bitcoin, blockchain technology shines brightly[2], The first cryptocurrency to enter people's daily lives has become a hot subject in today's software industry. [2]. Blockchain is an open distributed ledger made up of a chain of digital blocks that are linked and interconnected. It was created with the intention of storing only digital currency transactions, but it has subsequently evolved to incorporate additional applications. [13]. There are also various sorts of Blockchains based on their purpose and characteristics: •
Public blockchain
•
Private blockchain
•
Consortium blockchain
• Time Stamp: uses universal time to stamp the current time in seconds. •
nBits: the minimum size of a valid block hash.
• Nonce: a mathematical value starts with 0 and increases with calculation of every hash. •
Parent Block Hash: refers to the block before it.
The transactions and transaction counter are stored in the block body. The maximum capacity of block to store the transactions is determined by the block size and size of each transaction contained in it. Fig 1.2 shows the structure of blocks in blockchain[12].
The main motivation for using blockchain is because of its features or properties, such as decentralization, transparency, and immutability. Blockchain is a distributed ledger to store the digital transactions between two parties efficiently [2]. The
