The Ethereum blockchain API enables developers to interact with the Ethereum network through standardized methods like JSON-RPC. One of the most critical use cases is retrieving events from smart contracts – essential for tracking blockchain activity, triggering off-chain processes, or…
zkSync stands out as one of the most promising Layer 2 solutions. Leveraging zk-rollups technology, zkSync offers fast, secure, and cost-effective transactions. But how do developers actually interact with zkSync’s network? The answer is zkSync RPC – your gateway for…
Ethereum is back in the spotlight in 2025, navigating fierce competition from Solana, BNB Chain, and a host of Layer 2 (L2) solutions. After a long period of stagnation in on-chain activity and price, Ethereum’s latest updates-Pectra and the upcoming…
On May 7th, 2025, Ethereum officially launched Pectra, a major upgrade combining Prague (execution layer) and Electra (consensus layer). This is not just another update – it’s a significant transformation that impacts both stakers and validator operators. Let’s break down…
Validium is one of the advanced approaches to scaling blockchain networks, especially Ethereum. Its main goal is to make blockchain interactions faster, cheaper, and more private — all without compromising security. At the heart of Validium is the idea that…
WebSocket testing has become an essential part of modern Web3 development. It allows developers to test real-time communication between clients and servers, enabling interactive and dynamic web applications. With NOWNodes, you can easily create WebSockets subscriptions to blockchain networks and…
Ethereum roadmap is here! The focus is shifting from theoretical idealism toward practical engineering — scalability, performance, simplicity. This isn’t a pivot; it’s a natural evolution. The network is maturing into what it was always meant to be: a general-purpose…
Ethereum is approaching one of its most significant updates—Pectra. Developers have successfully activated it on the Sepolia testnet, meaning the main launch is just around the corner. We have already updated and are ready for the upcoming changes. Let’s break…
In anticipation of the upcoming Ethereum update – Pectra, client software updates essential for node and validator operations have been released. Two key releases—Geth 1.15.2 and Prysm 5.2.0—are closely connected and introduce important changes in block processing, network synchronization, and…
Artificial intelligence (AI) and blockchain are two transformative forces reshaping the digital world. AI enhances industries through advanced analytics, predictive capabilities, and innovative automation, while blockchain revolutionizes finance, governance, and digital ownership through decentralized finance (DeFi), non-fungible tokens (NFTs), and…
