A Solana RPC provider is a service that gives your application access to the Solana blockchain through hosted nodes, so you can read account data and submit transactions without running your own infrastructure. NOWNodes, Helius, QuickNode, Alchemy, Chainstack, and Triton…
An XRP RPC provider gives your application hosted access to the XRP Ledger, so a wallet, exchange, or bot can read balances and submit transactions without running a rippled server. NOWNodes, QuickNode, GetBlock, Chainstack, and dRPC all offer this, and…
A BNB Smart Chain RPC provider is a service that gives your application access to BSC through hosted nodes, so wallets, dApps, and bots can read chain data and send transactions without running node infrastructure in-house. NOWNodes, Ankr, Chainstack, QuickNode,…
A modular blockchain hands off one or more of its core jobs — execution, settlement, consensus, or data availability — to a separate specialized chain instead of doing everything itself. A monolithic blockchain keeps all four of those jobs on…
MEV — maximal extractable value — is the extra profit someone can pull out of a blockchain by choosing which transactions go into a block and in what order, beyond the normal block reward and gas fees. An MEV attack…
A fraud proof lets anyone catch and reverse a bad transaction after it’s already been assumed correct. A validity proof checks the math before anything is assumed at all. Both exist to answer the same question for a very different…
Calldata is the read-only area where an external function’s arguments sit while a Solidity transaction runs — the raw call data attached to the transaction itself, and the cheapest of Solidity’s three data locations. It’s the one you should reach…
AI tools for blockchain development fall into two distinct categories: tools that write, generate, or audit code, and the infrastructure that connects those tools to live chain data for agentic workflows — where an AI agent checks a wallet balance…
The web3 stack is the set of tools a developer combines to build an app that reads and writes to a blockchain: a network to build on, a way to connect to it, smart contracts, a wallet for users, and…
A cross-chain bridge is a protocol that lets you move a token or a piece of data from one blockchain to another, even though the two networks weren’t built to talk to each other. Bitcoin, Ethereum, Solana, and BNB Smart…
