Good news: you don\u2019t have to anymore.<\/p>\n\n\n\n<p><a href=\"https:\/\/nownodes.io\/\">NOWNodes<\/a> has just made the Ethereum archive node available in the shared plan, meaning you can now query the entire blockchain history without renting your own dedicated instance or managing terabytes of data.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"what-is-an-archive-node\">What Is an Archive Node?<\/h3>\n\n\n<p>Let\u2019s start with the basics. In Ethereum, there are two main types of nodes: full nodes and archive nodes.<\/p>\n\n\n\n<p>A full node keeps the current state of the network \u2014 it verifies transactions, syncs new blocks, and holds enough data to validate everything that\u2019s happening right now.<\/p>\n\n\n\n<p>An archive node, on the other hand, keeps <em>everything<\/em>. It stores the complete node history, from the genesis block to the latest one, including every past account balance, smart contract, and state change.<\/p>\n\n\n\n<p>That\u2019s why when you compare full node vs archive node, it comes down to this:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A full node knows what\u2019s happening now.<\/li>\n\n\n\n<li>An archive node remembers what\u2019s happened <em>since day one<\/em>.<\/li>\n<\/ul>\n\n\n<h3 class=\"wp-block-heading\" id=\"why-node-history-matters\">Why Node History Matters<\/h3>\n\n\n<p>Having access to full node history opens up a world of possibilities.<br>Need to check the balance of a wallet from 2017? Want to analyze how a smart contract evolved over time? Building a DeFi dashboard or blockchain explorer?<br>That\u2019s where an Ethereum archive node shines.<\/p>\n\n\n\n<p>Without it, you\u2019re stuck with the current state only \u2014 all historical data is lost or pruned away. With an archive node, every bit of blockchain history is just one query away.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"geth-archive-node-vs-erigon-archive-node\">Geth Archive Node vs Erigon Archive Node<\/h3>\n\n\n<p>Most people think of a Geth archive node when they hear about Ethereum data access. Geth (Go Ethereum) was the original, but it\u2019s also huge \u2014 running a full Geth archive can take over 15 terabytes of storage.<\/p>\n\n\n\n<p>NOWNodes takes a smarter route: we use Erigon, a modern, highly optimized Ethereum client designed for speed and efficiency. An Erigon archive node stores the same data as Geth but in a much more compact form. It syncs faster, uses less disk space, and still delivers all the rich historical data you need through the same JSON-RPC interface.<\/p>\n\n\n\n<p>In short: same power, less hassle.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"ethereum-archive-node-access\">Ethereum Archive Node Access<\/h3>\n\n\n<p>You can now access Ethereum\u2019s complete archive without managing servers, syncing nodes, or handling maintenance. NOWNodes offers a ready-to-use <a href=\"https:\/\/nownodes.gitbook.io\/eth-ethereum\/ethereum-eth\/mainnet\/erigon-archive-node-evm\">Ethereum archive endpoint<\/a>, powered by Erigon, so you can simply connect and start exploring the full blockchain history right away.<\/p>\n\n\n\n<p>But that\u2019s not all \u2014 this isn\u2019t just a standard EVM endpoint. With NOWNodes, you also get access to advanced <a href=\"https:\/\/nownodes.gitbook.io\/eth-ethereum\/ethereum-eth\/mainnet\/erigon-archive-node\">Erigon and trace-level methods<\/a> that go far beyond typical JSON-RPC calls.<\/p>\n\n\n\n<p>These powerful features let you:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Retrieve detailed block and header data straight from Erigon\u2019s optimized backend<\/li>\n\n\n\n<li>Access historical logs and transaction traces for any block or contract<\/li>\n\n\n\n<li>Replay and analyze past transactions at the deepest execution level<\/li>\n\n\n\n<li>Perform granular tracing of smart contract calls, gas usage, and internal operations<\/li>\n<\/ul>\n\n\n\n<p>In other words, you\u2019re not just seeing <em>what happened<\/em> on Ethereum \u2014 you can now understand <em>how<\/em> it happened.<\/p>\n\n\n\n<p>Whether you\u2019re verifying smart contract behavior, auditing historical transactions, or building analytics tools that depend on precise historical state, the <strong>Erigon archive node<\/strong> on NOWNodes gives you both the depth and the flexibility you need \u2014 instantly, securely, and at scale.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"ready-to-explore-ethereums-past\">Ready to Explore Ethereum\u2019s Past?<\/h3>\n\n\n<p>With <a href=\"https:\/\/nownodes.io\/\">NOWNodes<\/a>, you can now query any block in Ethereum\u2019s history as easily as you query the latest one.
