# The Blockchain Toll Road Metaphor

## The Metaphor

To explain the utility of Layer 1 blockchains and their native tokens, [[entity-alexandra-damsker|Damsker]] uses a highly effective metaphor:

> A blockchain like [[entity-ethereum|Ethereum]] is a **toll road**. The native token (ETH) is the **toll** required to drive on it.

## How It Works

If you want to:

- Build a business on the chain
- Execute a smart contract
- Transfer an asset

...you must pay a fee — **'gas'** — to use that specific infrastructure. The native token of the chain is the only currency accepted for that toll.

## Implication for Token Value

The value of the token is directly tied to the demand for using the road:

- If many developers and users want to transact on Ethereum, demand for ETH increases.
- ETH is the only acceptable payment for gas.
- Therefore ETH price reflects (in part) demand for using the chain.

This demystifies why certain cryptocurrencies have value *beyond mere speculation*: they are the required utility token for accessing decentralized infrastructure.

## Validation

The enrichment overlay confirms this analogy as broadly correct: ETH is used to pay network gas fees for executing transactions and smart contracts on Ethereum.
