The Ethereum network is powerful, but it can be slow and expensive during periods of high demand. That’s where Optimism comes in — a Layer 2 scaling solution designed to make Ethereum faster and more cost-effective. It’s an ideal choice…
As blockchain technology advances, Layer-2 scaling solutions are gaining significant traction. Base is designed to offer a scalable, cost-efficient alternative to Ethereum while maintaining full EVM compatibility. With fast finality, reduced fees, and access to Ethereum tooling, Base has quickly…
In a blockchain world racing toward scalability, speed, and speculation, there’s one network that still commands trust above all: Bitcoin. But while Bitcoin remains the strongest and most secure ledger on Earth, one question continues to echo through the developer…
As the demand for Bitcoin utility grows beyond store-of-value use cases, Babylon Chain emerges as a critical protocol within the Babylon ecosystem. In other words, it introduces a novel architecture for Bitcoin staking, allowing BTC holders to participate in securing…
Today, Polygon (POL) is a highly scalable and developer-friendly blockchain network. Moreover, to enable seamless interaction between wallets and the Polygon network, integrating via JSON-RPC is essential. This guide will walk you through the process using NOWNodes’ Polygon RPC endpoints, covering all the…
On May 27, 2025, Horizen released ZEN 5.0.7, the latest version of its node software for Mainnet. NOWNodes has already completed the upgrade across all Horizen nodes, ensuring a fully compliant, stable, and production-ready environment for developers building on the…
In the Avalanche ecosystem, scalability is not just about faster block times – it’s about customization and flexibility. Avalanche introduces a novel architecture called Subnets that enables developers and enterprises to create isolated blockchain environments tailored to their needs. If…
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…
Since its launch, Monero has become synonymous with cryptographic privacy. Unlike most public blockchains where anyone can trace the flow of funds, Monero’s network is built on principles of complete confidentiality, implemented directly at the protocol level. This architecture makes…
Among the leading contenders in Ethereum Layer 2 space are Arbitrum and Optimism. Both use optimistic rollups to offload computation from the main Ethereum chain, drastically reducing fees and improving throughput. While they share the same goal, their node architecture…
