Coin

A coin is a type of cryptocurrency that operates on its own native blockchain, serving as a digital currency or a foundational asset for its ecosystem—distinct from tokens, which are built on top of existing blockchains like Solana.

Crypto Terminology

Coin: what is it?

In the context of blockchain and cryptocurrencies, a coin is a digital asset with its own dedicated blockchain network. Unlike tokens, which rely on an existing blockchain’s infrastructure and standards to exist (for example, SPL tokens on Solana), coins form the core utility and value exchange medium of their respective blockchains. Coins are used for paying transaction fees, powering on-chain applications, staking, and ensuring network security via various consensus mechanisms.

How It Works

Coins are integral to the functioning of their native networks. At the network level, they incentivize validators or miners and act as “gas” for transactions and operations. For example, SOL is the native coin of the Solana blockchain, used to pay network fees and participate in staking for network security. Coins may also serve as a foundation for launching supplementary tokens, supporting decentralized applications, and facilitating peer-to-peer digital payments.

Coin in Solana’s Ecosystem

On Solana, SOL is the native coin that provides the economic backbone for the network. All transaction fees, staking operations, and network incentives involve SOL. Unlike Solana-based tokens (SPL tokens), SOL is issued by and tied directly to the Solana blockchain—the protocol would not function without it.

Why Are Coins Important?

Coins are essential because they deliver both the core utility and value layer for blockchain ecosystems. The security, speed, and capability of a network typically depend on the robust design and adoption of its native coin. Coins also often reflect network health and community participation.

🔑 Key points

  • A coin possesses its own standalone blockchain (e.g., SOL for Solana, BTC for Bitcoin).

  • It underpins network security, transaction validation, and on-chain operations.

  • Distinct from tokens, which are created on and secured by existing blockchains.

  • Coins are vital for protocol-level governance and utility.

Examples

  • 1

    SOL (Solana): The native coin of the Solana blockchain.

  • 2

    BTC (Bitcoin): The pioneering digital coin and blockchain.

  • 3

    ETH (Ethereum): Ethereum’s native coin.

  • 4

    Other blockchain-native coins: ADA (Cardano), AVAX (Avalanche).

Common Use Cases

Paying network and transaction fees.
Staking and validating blocks for network consensus.
Facilitating transfers and value storage.
Backbone for all applications and tokens residing on the protocol.

Pro Tips

💡

Always distinguish between coins (native to their networks) and tokens (built atop existing chains).

💡

Holding coins like SOL typically grants you the ability to participate in network security (staking) and governance.

💡

Monitor coin-related metrics for insight into the network’s health and usage.

Frequently Asked Questions

What is the difference between a coin and a token?
A coin is the primary digital asset of a native blockchain (SOL on Solana), while a token exists within the infrastructure of another blockchain (like SPL tokens on Solana).
Do I need coins to use Solana dApps?
Yes, SOL is required to pay transaction fees and interact with applications built on Solana.
Are all cryptocurrencies considered coins?
No, only cryptocurrencies with their own blockchains are coins. Others, built on top of those chains, are considered tokens.
Can coins be traded like tokens?
Yes, coins can be traded on both centralized and decentralized exchanges, typically as the primary liquidity or value asset on their network.
