Furthermore, recognizing how these layers interact is essential for grasping the broader mechanics of decentralized finance. When developers launch a new project, they must decide whether to build a custom ledger from scratch or leverage the security and infrastructure of an established ecosystem.

The Role of Smart Contracts
Networks that support programmable logic allow creators to issue thousands of custom assets without writing low-level code for a new distributed ledger. This capability drastically reduces development time and deployment costs, fueling the massive proliferation of alternative digital assets available on the market.
To understand the landscape of digital assets, one must distinguish between coins and tokens. A coin is a cryptocurrency that operates on its own independent blockchain. These are the foundational layers of the ecosystem, providing the consensus mechanisms, security protocols, and native assets that power the entire network. Examples include Bitcoin, Ethereum, Solana, and Cardano. Each of these functions as the base infrastructure for its respective ecosystem.
Conversely, tokens do not possess their own independent blockchain. Instead, they are built on top of existing networks using smart contract functionality. These assets leverage the security and consensus of the underlying “parent” chain while operating as secondary layers. Most tokens found on decentralized exchanges are created this way, utilizing standards such as ERC-20 on the Ethereum network or SPL on the Solana network.
Why the Distinction Matters
- Native Coins: These assets are essential for paying transaction fees (gas) and securing the network through mining or staking. They represent the primary currency of their specific blockchain.
- Tokens: These assets serve various purposes, such as utility within a specific decentralized application (dApp), governance rights, or representing real-world assets (RWA), but they rely on the host blockchain to process their transactions.
Ultimately, the proliferation of tokens has made it easier than ever to launch new projects, but it is vital to recognize that the security of these assets is intrinsically linked to the underlying blockchain they reside upon. While every coin is a blockchain-native asset, thousands of cryptocurrencies are simply specialized tokens thriving within the ecosystems created by a select few foundational blockchains.
