Ether, Explained

Ether* is the coin. Ethereum* is the network. It’s important to distinguish between the two. 

Ether is a programmable, utility-bearing, and variable-supply cryptocurrency that runs on the Ethereum network. These three traits set it apart from earlier digital assets.

The network underpins a variety of other platforms and applications. This idea for Ethereum was to build off of the existing crypto ecosystem and introduce a more scalable protocol that enabled use cases beyond simple digital asset storage and transfer.

This explainer will walk through Ether and Ethereum with a perspective focused on how to approach it as an investable asset.

Not Just a Ledger

Ethereum is a decentralized network of nodes* that share a record of activity, called a blockchain*.

Where the Ethereum network differs is in its ability to hold smart contracts*. These are self-executing programs stored on the blockchain. They automatically carry out the terms of an agreement when predefined conditions are met. These contracts are the building blocks for decentralized applications that utilize the Ethereum rails and make Ether programmable.  

The initial block of Ether was mined on July 30, 2015, marking the launch of the Ethereum network.¹ It was created by Vitalik Buterin and a team of founders. They used the successes and failures of earlier cryptocurrencies as guides to mold Ethereum into a general-purpose platform that could serve as a base for other applications.

Ether Works for a Living

Every action on Ethereum costs Ether. This is why it’s utility-bearing. Transfers, smart-contract execution, and minting all have embedded Ether costs that are referred to as gas. Gas serves two main functions on the network. It incentivizes the processing of transactions by operators via priority fees. It also limits spam on the network by capping each block's gas capacity.²

Gas prices float. They go up when demand increases on the network and drop during quiet periods. This is how the network meters demand for computational capacity. Since 2021, the base fees are burned rather than paid out. This change was introduced via EIP-1559*. EIP stands for Ethereum Improvement Proposal. These are suggestions for changes to the network that are considered by the developers, researchers, and stakeholders in the network.

How Ethereum Learned to Love the Stake

At launch, Ether used proof-of-work similar to earlier cryptocurrencies. However, it was always the intent of the developers to have the network transition to proof-of-stake*.

This transition process took longer than initially forecast with deployment of a parallel proof-of-stake test network on December 1, 2020, and The Merge³ when the original proof-of-work blockchain merged with the proof-of-stake blockchain, on September 15, 2022.

Proof-of-stake is markedly different from proof-of-work. It’s a consensus mechanism in which validators are selected to confirm network transactions based on the amount of cryptocurrency they have committed (staked*) to it. This staking reward system replaced mining rewards and lowered the energy consumption of the network by ~99.95%.³

Staking is the process of committing tokens to a proof-of-stake blockchain network in exchange for the opportunity to validate transactions and earn rewards. Staking yields vary by network and depend on factors such as total stake, network activity, and validator performance.

It's important to look at honest validators as network security rather than simply earning some kind of reward. If a validator is dishonest or offline, they lose a portion of their staked Ether. This self-reinforcing loop encourages honest participation. The yield is a byproduct of securing the network rather than its primary purpose.

There are a number of different ways for investors to access staking rewards. 

Self-custodying Ether owners with at least 32 Ether and a functional node can directly stake their tokens. 

There are services and exchanges that will let you contribute to their staking assets for a fee cut of the staking reward. This does introduce counterparty risk but delegates the responsibility of network management to a third party.

Liquid staking tokens (LSTs) are a second layer version of staking services focused on allowing holders to have liquidity and avoid lockups associated with the other staking servicers.

The final and newest access point is with spot staking-enabled exchange-traded products (ETPs). The first staking-enabled spot products arrived in late 2025, the first reward distribution to shareholders was January 2026, and a March 2026 SEC/CFTC interpretive release subsequently classified staking rewards as non-securities.^4,5 These are tradeable on traditional finance (TradFi) rails via a standard brokerage account.

No Caps, Burning, and Issuance

Ether's supply is variable, with no fixed cap. Earlier cryptocurrencies had a supply cap, which created implied scarcity. Instead, Ether has a variable supply with methods for the creation and destruction of tokens.

New Ether tokens are created as a function of staking rewards. They are earned via the validation process we outlined above. The base token fees are destroyed (or burned) with every transaction.

This burn fee was introduced above with EIP-1559 and means the net token supply is floating based on demand in the system. There have been periods of inflation and deflation since The Merge. Heavy usage of the network is deflationary when burn outpaces new issuance. Quiet usage periods are inflationary with net supply rising as less Ether is burned.

Code governs Ether’s supply, and that supply responds to network usage. No central authority controls it. That combination separates Ether from both traditional fiat currency and other crypto networks, putting it in its own category.

Ether, Investable Asset

Investors looking at Ether should be mindful of a number of points that can influence their potential positioning. 

The first is volatility*. Ether is highly volatile, with large price swings. Large drawdowns have been common, so position sizing should be carefully considered. It has a varied relationship with other assets both in crypto and across the broader market, so correlation is an unreliable benchmark for Ether. The only common theme is that it tends to exhibit more volatility than broad crypto benchmarks or equities.

The second is yield. Some access points have a staking yield component, and some don’t, only offering price exposure to the product. How you decide to hold Ether will dictate whether you will earn staking yield. 

Accessibility is the next point to consider. Spot ETPs and staking-enabled spot ETPs have brokerage-based access points for TradFi investors though the staking-enabled products only pass through yield net of fund fees. Self-custody of Ether allows direct control of assets and staking yield without tying into existing rails for traditional finance. LSTs and staking services reduce some of the operational burden in return for some of the staking yield and again keep the investor outside of the TradFi rails.

Regulations around staking rewards, tax treatment, and product rules are slowly being defined but are far from being settled. The SEC/CFTC has classified staking rewards as non-securities but there hasn’t been commensurate tax treatment guidance nor firm product guardrails established to codify norms.

Ether, Integrated

Ether and the Ethereum network are not part of the standard investor playbook yet. Ethereum is rapidly being adopted and used by platforms for applications and a variety of use cases. Ether is getting more integrated into both the TradFi investment universe and is an important part of the DeFi (decentralized finance) ecosystem. It's programmable, utility-bearing, and has a variable supply; and because it runs on proof-of-stake, it's far less energy-intensive than proof-of-work networks.
