Ethereum
Overview
The aim of this project was to gain firsthand experience with Ethereum, a leading blockchain platform, focusing on public-key signature, hash function, key management, and proof-of-work mechanisms. This endeavour was designed to deepen our understanding of how cryptographic algorithms are employed in practice, encouraging an incentive to learn more about these algorithms.
Objectives
To setup a private Ethereum network. To execute transactions and mine Ethereum tokens. To explore the application of cryptographic techniques within Ethereum.

Part I: Running a Private Ethereum Network
Task Description
We started by creating a genesis block for our private Ethereum network and initiating it using the provided ‘geth’ binary.
Steps Followed
Genesis Block Creation: Crafted a genesis file to describe the initial configuration of our private Ethereum network.
Initializing the Private Network: Utilized the geth command to initialize the network with our genesis block.
Command: ‘./geth init /home/kali/Desktop/genesis’Starting the Network: Launched our private Ethereum network while enabling the geth console and configuring it to avoid discovering public networks. Command: ‘./geth --nodiscover --networkid 9724 console’ Note: Here, ‘9724’ is a placeholder for our unique network ID.
Outcome
Successfully initiated our private Ethereum network and accessed the geth console for further operations.
Outcome
After mining, the etherbase account received Ethereum tokens as rewards, demonstrating the blockchain's growth and the function of mining.
Part III: Creating Transactions and Mining into Blocks
Task Description
Executed transactions between the two accounts and ensured they were mined into the blockchain.
Steps Followed
- Stop Mining: Temporarily halted the mining process to prepare for the transaction. Command: ‘miner()’
- Transaction Execution: Created and sent a transaction from the etherbase account to the other account. Command: ‘eth({from: eth[ 0 ], to: eth[ 1 ], value: web3( 1 , “ether”)})’ Note: In Ethereum accounts are blocked by default for security reasons, requiring the user to unlock them before transactions. o To resolve this issue, we temporarily unlocked our account using the following command: ‘personal(eth[ 0 ], "YourPassphraseHere", 15000 )’ Here, ‘15000’ denotes the time (in seconds) for which the account will remain unlocked.
- Transaction Verification: Verified the transaction in the pool and resumed mining to confirm it in the blockchain. We first verified the transaction by checking the transaction status using the following command: ‘txpool’
