Whenever we need to query data from the blockchain, we fetch it from a node. An archive node differs from a full node since the first holds the entire history of network transactions. Thus, some queries for older block transactions cannot be fetched easily on a full node. In this tutorial, we will programmatically fetch data from the blockchain, switching between full and archive nodes when necessary.

Ape is a Python smart contract development and testing framework by ApewWorX, focusing on a modular approach.

An overview of decentralized storage systems focusing on Arweave and Bundlr and building a decentralized music marketplace app using these protocols.

Learn about the current landscape of all the possible Layer 1 and Layer 2 solutions that are built for scaling. This includes sidechains, rollups, ZK EVMs, and dedicated networks.

This tutorial shows you how to use Python scripts in the Brownie framework for contract deployment and testing.  We will also learn how to work with actual Ethereum testnets while using Brownie.

In this article, we will explore two different approaches on how an EVM-based blockchain generates contract addresses when deploying new instances on different networks: the classic way and a deterministic approach.
