When working with Python, a programmer often encounters situations where she needs to install packages not contained in the Standard Library. In such situations, she must install modules from online repositories using packager installers. The goal of this article is to help beginners develop a working knowledge of pip (acronym for “PIP Installs Packages”) as

This post provides insights into the replay attack in blockchains. As per the wiki, a replay attack is a valid data transmission that is maliciously or fraudulently repeated or delayed. In the case of blockchains, a replay attack means taking a transaction on a  blockchain and maliciously or fraudulently repeating it on the same or

In this tutorial, the randomness attack or also called replicated logic attack is analyzed. The problem in Solidity contracts is finding the true source of randomness. We will see how generating a random number using on chain data cannot be trusted.   The tutorial starts with exploiting the randomness vulnerability, followed by the possible solutions. Let

The DelegateCall attack or storage collision is expounded in this post. Before you can grasp this exploit, you must first understand how Solidity saves state variables as explained here.  We start with the differences between call and delegatecall in Solidity, followed by exploiting the vulnerability of the delegatecall using the proxy contracts (mostly in smart
