Abstract

Smart Contract Watch is an open-source Blockchain & Cloud Computing project. A tool to monitor a number of smart contracts and transactions. A smart contract monitoring tool. It can monitor smart contracts activity and interactions based on generated transactions and events.For example, It can be used a local blockchain explorer that runs locally on your server or machine ,or as an investigation tool that scrapes the blockchain in search for a specific query. It is built using JavaScript, Solidity, Ethereum. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Blockchain & Cloud Computing mini project or final-year project.

1. Introduction

A smart contract monitoring tool. It can monitor smart contracts activity and interactions based on generated transactions and events.For example, It can be used a local blockchain explorer that runs locally on your server or machine ,or as an investigation tool that scrapes the blockchain in search for a specific query. This is done by sending requests to an Ethereum node via JSON RPC calls.

For example, if -b is set to 20 the smart contract watch will wait until block hight is at least 20.

Sometimes single codes are caught on side chains, uncles. these side chains have a minimal chance of carrying blocks with transactions that got discarded in the main ledger due to ethereum's consensus algorithm. In order to tackle this, a confirmations block option was added to specify the number of block confirmations before recording transactions in that block.

2. Objective

A tool to monitor a number of smart contracts and transactions

This project demonstrates how JavaScript, Solidity, Ethereum can be applied to a real-world Blockchain & Cloud Computing problem.

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Why does this problem need a blockchain or cloud-native design?
  2. Explain the smart contract / infrastructure components and how they interact.
  3. How are gas costs or cloud costs kept under control?
  4. How is the system secured (keys, IAM, access control)?
  5. How would the solution scale to many more users?
