Ethereum’s monetary system combines two opposing forces. Staking creates new ETH to reward validators, while its fee-burning mechanism permanently removes ETH from circulation. The balance between issuance and burning determines whether Ethereum’s total supply expands or contracts. Unlike Bitcoin, Ethereum therefore does not have a fixed maximum supply.

Ethereum transitioned from Proof-of-Work to Proof-of-Stake through the Merge in September 2022. Since then, validators have secured the blockchain by staking ETH rather than miners competing through computational work.

How Ethereum Staking Works

A trader must buy and hold at least 32 ETH to become a solo validator on the Ethereum network. The validator must propose blocks and declare whether or not the blocks proposed by other validators are valid.

Valid participation leads to the generation of ETH rewards, while the validator may face penalties for remaining offline or violating network rules.

The Ethereum network's Pectra upgrade made notable changes in staking. The implementation of EIP-7251 increases the maximum amount of ETH that can be used by the validator from 32 ETH to 2,048 ETH, but the minimum amount of ETH remained 36 ETH. Compounding validators can earn rewards from other ETH in increments of one ETH without the need to launch separate validators for their stake of 32 ETH.

Users without 32 ETH can still enjoy staking through staking pools where they can deposit less than 32 ETH. The ethereum.org reports that in some pools people can invest as little as 0.01 ETH.

Ethereum Staking Demand Remains High

Approximately 43.6 million ETH was staked in early October 2026. On October 5, around 1.5 million ETH, worth roughly USD 4 billion at the time, was waiting to enter staking. The estimated entry wait was approximately 25 days, down from around two million ETH and 35 days in early September.

Meanwhile, approximately 786,000 ETH was waiting to exit, with an estimated delay of nearly 14 days. Ethereum limits entries and exits to protect network stability when validator demand changes sharply.

How Ethereum Burns ETH

EIP-1559 introduced Ethereum’s fee-burning mechanism in 2021. Each transaction includes a protocol-determined base fee that is permanently destroyed rather than paid to validators.

Ethereum’s supply consequently depends on two primary forces: Proof-of-Stake issuance creates ETH, while EIP-1559 burning destroys ETH.

If validator issuance exceeds the amount burned, ETH supply expands. When transaction activity pushes burns above issuance, supply contracts. Ethereum is therefore not permanently inflationary or deflationary.

Network Activity Changes the Balance

Heavy DeFi trading, token launches, and other mainnet activity can increase transaction fees and consequently ETH burning. However, Ethereum increasingly processes activity through Layer 2 networks. 

Lower mainnet fees can reduce ETH burned even while the broader Ethereum ecosystem processes substantial transaction volumes. This makes network usage, validator issuance and Layer 2 activity important when analysing ETH’s changing supply.

Final Thoughts

Ethereum staking secures the network while creating new ETH as validator rewards. EIP-1559 works in the opposite direction by permanently burning part of transaction fees. The balance between these mechanisms determines whether ETH supply expands or contracts over time.

FAQs:

1. How does Ethereum staking work?

Validators stake ETH to help secure Ethereum, propose blocks, and attest to valid network activity. In return, correctly participating validators receive ETH rewards.

2. How much ETH is required to run a solo validator?

A solo validator requires a minimum of 32 ETH. Users with smaller holdings can participate through staking pools, although these introduce additional provider or smart-contract risks.

3. What did EIP-7251 change for Ethereum validators?

EIP-7251 increased the maximum effective balance of a validator from 32 ETH to 2,048 ETH. The minimum requirement remains 32 ETH, not 36 ETH.

4. How does Ethereum burn ETH through EIP-1559?

EIP-1559 introduced a base transaction fee that is permanently removed from circulation. Higher mainnet transaction activity can therefore result in more ETH being burned.

5. Is Ethereum inflationary or deflationary?

Ethereum can be either, depending on network conditions. Supply expands when staking issuance exceeds ETH burned and contracts when transaction-fee burns exceed new issuance.
