The Ethereum ecosystem depends on reliable and consistent testnets to ensure the safe development, deployment, and testing of smart contracts and decentralized applications. As legacy networks like Ropsten and Goerli are deprecated, Sepolia has emerged as one of the two…
A blockchain node is a crucial element of any decentralized network, responsible for storing, verifying, and distributing blockchain data. Without nodes, cryptocurrencies and smart contracts wouldn’t function, as they enable transaction validation and network security. One of the most efficient…
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…
As of January 23, 2025, Ethereum has topped blockchain earnings in 2024, collecting an impressive $2.48 billion in fees despite the Dencun upgrade in March that aimed to reduce costs on the network, according to CoinGecko. This remarkable achievement reinforces…
As Web3 technology continues to reshape digital infrastructure in 2025, choosing the best Ethereum RPC service for Web3 has become a critical decision for developers and organizations building decentralized applications. The RPC layer (Remote Procedure Call) is the communication bridge…
Let’s be honest — the term “Ethereum node” doesn’t exactly scream excitement. It sounds technical, dry, maybe even a little intimidating. But here’s the twist: if you’ve ever used MetaMask, swapped tokens on Uniswap, or browsed a block explorer —…
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…
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…
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…
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…
