We are excited to announce that we have successfully upgraded our Cosmos Network node to the latest version, Gaia v24.0.0. This is a critical network upgrade, officially passed via on-chain governance, and it marks an important architectural evolution for the…
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…
Solana is a high-performance blockchain used for building decentralized applications (dApps) with a focus on speed and scalability. To interact with the Solana blockchain, developers use RPC (Remote Procedure Call) endpoints — gateways that allow querying account balances, sending transactions,…
Crypto wallets are the front doors of Web3. For millions of users, they are the interface to digital assets, decentralized applications, and financial sovereignty. But behind the sleek interfaces of wallets lies complex infrastructure – and one of the most…
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…
The Solana blockchain is recognized for its impressive throughput and minimal fees, establishing it as one of the leading options for decentralized applications and financial instruments. Regardless of whether you are developing a wallet, a decentralized exchange, or a data…
