Avalanche

Ethereum

X-Chain

when

<p>Avalanche (<a href="https://x.com/avax" rel="noopener noreferrer nofollow">@avax</a>) does not run on a single blockchain. Its main network, called the Primary Network, is split across three chains: the C-Chain, the P-Chain and the X-Chain. Each handles a different task, and the split affects how users hold, move and spend <a href="https://x.com/search?q=%24AVAX&amp;src=cashtag_click" rel="noopener noreferrer nofollow">$AVAX</a>.</p>
<h2 id="what-each-avalanche-chain-does">What each Avalanche chain does</h2>
<p><cite>According to Avalanche's developer documentation, the Primary Network is a special Avalanche L1 that runs three blockchains: the Contract Chain (C-Chain), the Platform Chain (P-Chain) and the Exchange Chain (X-Chain).</cite></p>
<p>The C-Chain is where most application activity takes place. <cite>It is an implementation of the Ethereum Virtual Machine, and its API supports the deployment and execution of smart contracts written in Solidity.</cite> That EVM compatibility means apps built for Ethereum can run on it.</p>
<p>The P-Chain handles the network's coordination layer. <cite>It is responsible for validator and Avalanche L1-level operations, including staking and the creation of new blockchains and Avalanche L1s.</cite></p>
<p>The X-Chain is where assets are created and moved. <cite>It handles the issuance and trading of what are known as Avalanche Native Tokens.</cite> That includes $AVAX. <cite>The chain does not support smart contracts, and uses a simpler model.</cite></p>
<h2 id="helicon-changes-how-the-c-chain-executes-blocks">Helicon changes how the C-Chain executes blocks</h2>
<p>The C-Chain was reworked in September. <cite>Avalanche activated its Helicon upgrade on Mainnet on Sept. 22, introducing a new C-Chain execution model intended to increase processing capacity and speed receipt issuance during periods of heavy demand.</cite></p>
<p><cite>Its central feature, Continuous Execution, separates consensus from transaction execution by placing accepted blocks in a queue while a concurrent executor processes their transactions.</cite> In practical terms, the network can agree on the order of new blocks while still working through the transactions in earlier ones.</p>
<p>Helicon also touched validators. <cite>The minimum staking duration is now 48 hours, down from two weeks, while the effective uptime requirement for new validation periods rose to 90% from 80%.</cite></p>
<h2 id="why-avax-balances-are-kept-separate">Why AVAX balances are kept separate</h2>
<p>$AVAX is the fee token across the Primary Network, and each chain keeps its own balance. A holder therefore has to transfer AVAX to a given chain before using it there. The split also matters when sending funds. <cite>AVAX exists on three chains: on the X-Chain, where it can be traded, on the P-Chain, where it can be staked, and on the C-Chain, where it can be used in smart contracts or to pay for gas.</cite></p>
<p>Choosing the wrong chain is a common source of mistakes. <cite>A C-Chain address looks like an Ethereum address, 42 characters beginning with 0x, while X-Chain addresses begin with X-avax and P-Chain addresses with P-avax.</cite> Users should check which chain an exchange or wallet expects before sending.</p>
<p>The multi-chain design is central to how Avalanche positions itself against single-chain networks. By assigning smart contracts, staking and asset issuance to separate chains, the network keeps those workloads from competing for the same block space.</p>

Avalanche runs three blockchains at once, and each one has a different job
