cdr-billing-smart-contracts

This repository provides Call Detail Records (CDRs) billing using smart contracts written in Solidity. It enables telecom operators and service providers to manage billing processes transparently and efficiently on a blockchain network, ensuring accurate, immutable, and automated.

Prerequisite

• node Download
• nvm Download
• git Download

git clone https://github.com/MASDXI/cdr-billing-smart-contracts.git
cd cdr-billing-smart-contracts

Installing

To install all necessary packages and dependencies in the project, run command

yarn install

Compile the code

To compile the smart contracts, run command

yarn compile

Testing

To run the tests and ensure that the contracts behave as expected, run command

yarn test

Rationale

• The design approach not tied exclusively to solidity or evm-based but can be applied across various Distributed Ledger Technologies (DLTs) or blockchain frameworks that support turing-complete smart contracts.
• Avoid WRITE or UPDATE operation with sliding window algorithm for billing efficiently over a specified time period. This method helps in maintaining a consistent billing cycle by leveraging a sliding window mechanism that automatically accounts for time-based without needing constant manual updates.

Security Consideration

• AS-IS, when change the network blocktime total billing cycle will be recalculate
