The short answer is no. In its current architectural design, the Ethereum public blockchain cannot function without Ether (ETH). To understand why this is the case, one must look at the fundamental relationship between the Ethereum Virtual Machine (EVM) and its native asset.

The Role of Ether as Fuel
Ether is not merely a currency; it is the native token of the Ethereum network. It serves as the primary mechanism for paying “gas” fees. Every transaction, smart contract execution, or state change on the Ethereum blockchain requires computational power. Validators and miners expend resources to process these operations, and they must be compensated for their hardware, electricity, and time.
Without Ether, there would be no incentive for validators to secure the network. If transactions were free, the network would be vulnerable to spam attacks, where malicious actors could flood the chain with endless requests, effectively bringing the system to a halt. Ether acts as a natural deterrent against such abuse.
ERC-20 Tokens vs. Native Tokens
There is often confusion regarding tokens built on top of Ethereum (like ERC-20 tokens) and the native Ether token. While ERC-20 tokens reside on the Ethereum blockchain, they rely entirely on the underlying infrastructure of the network. They cannot pay for their own transaction fees because they are smart contracts, not the protocol-level currency that validators recognize for gas payments.
Can this change?
Some developers have proposed “gasless” transaction models or meta-transactions, where a third party (often a relayer) pays the gas fee on behalf of a user. However, even in these scenarios, Ether is still being used to pay the fee. The burden of payment is shifted, but the fundamental requirement for Ether remains.
The Ethereum blockchain is built upon the premise of an internal economic incentive structure. Ether is the lifeblood of this system. Removing it would require a complete redesign of the consensus mechanism and the core protocols of the network. As it stands, Ether is indispensable for the security, viability, and functionality of the Ethereum ecosystem.
