Is running an Ethereum node still profitable?
Running an Ethereum node can still be worthwhile, but profitability depends on what you count as a return. A full node or archive node rarely earns direct protocol revenue; it prov...
Can you compare dedicated versus shared node access for Solana RPC?
Shared Solana RPC pools many users behind common endpoints, so you get fast setup and low cost but contend for throughput, rate limits, and WebSocket slots. Dedicated Solana nodes ...
What Is a TON Public Node and When Should You Use One?
A TON public node is a shared RPC endpoint that lets you read TON blockchain data and submit transactions without running your own node. It is the fastest way to get a wallet, scri...
What is a Solana light node and when should you use one?
A Solana light node is a client that keeps only the state it needs to verify accounts and transactions, rather than storing the full ledger. It is useful for wallets, dashboards, a...
What is a Solana archive node, and when do you actually need one?
A Solana archive node keeps the full ledger history rather than pruning older slots, so you can query historical blocks, transactions, and account states that a standard node has a...
What can you actually do with a free Solana node endpoint?
A free Solana node endpoint is a shared RPC URL you can call without paying, usually for learning, prototyping, or low-volume scripts. It works for basic reads like getBalance and ...
Dedicated vs Shared Node Access for Solana RPC Providers: What Should You Compare?
Shared Solana RPC pools multiplex many applications onto the same node fleet, so you trade isolation and predictable throughput for low setup effort. Dedicated node access gives yo...
Polygon Node Hosting: When to Rent Infrastructure Instead of Running It
Polygon node hosting means running the Polygon PoS stack — an Erigon or Bor-style execution client plus a Heimdall consensus client — on infrastructure someone else operates, so yo...
Top RPC solutions with dedicated node access for Solana: how do you evaluate them?
Dedicated Solana node access means you get a private RPC endpoint backed by infrastructure reserved for your workload, rather than sharing a public or pooled endpoint with other tr...
What Is a TON Full Node and When Should You Run One?
A TON full node stores the complete blockchain state and validates transactions for The Open Network. Running one gives you direct access to TON data without intermediaries, but it...
Sonic RPC Node: How to Connect to Sonic Mainnet
Sonic is an EVM-compatible Layer 1 blockchain designed for high-throughput DeFi applications. To interact with Sonic, developers need a reliable RPC node that can handle JSON-RPC r...
Fantom Node: What Is It and How Do You Connect to Fantom Opera?
A Fantom node is a client that maintains the Fantom Opera blockchain state and serves JSON-RPC requests. You can run your own node or use a managed RPC service. This article explai...
