Early Ethereum Mining and PoW Mechanism
Prior to September 2022, the Ethereum network utilized a Proof-of-Work (PoW) consensus mechanism similar to Bitcoin. During this phase, miners performed high-intensity mathematical hashing operations using computer hardware to compete for block production rights and secure the network. Miners who successfully packaged blocks were rewarded with system-issued block rewards and transaction fees.

The Ethash Algorithm and Characteristics of GPU Mining
Ethereum's PoW mining centrally relies on the Ethash algorithm. Designed to be ASIC-resistant (Application-Specific Integrated Circuit), the algorithm requires substantial memory bandwidth and relies on a dynamically generated DAG (Directed Acyclic Graph) dataset. Consequently, during the PoW era, Ethereum mining primarily depended on high-performance GPUs (graphics cards) for computations. This made it feasible for individuals to assemble GPU rigs to participate in mining and once fueled a massive retail graphics card market.
The "Merge" Upgrade and the End of the Mining Era
On September 15, 2022, Ethereum officially completed the highly anticipated "The Merge" upgrade. This upgrade marked the definitive transition of Ethereum's consensus mechanism from the energy-intensive Proof-of-Work (PoW) to Proof-of-Stake (PoS).
Under the PoS mechanism, traditional mining rigs, GPU mining, and high-intensity hashing operations exited the historical stage. Network block production and security maintenance were shifted to validators who have staked ETH. The legacy miner community faced choices regarding hardware repurposing, migrating to other PoW coins, or exiting the mining ecosystem. Today's Ethereum mainnet no longer generates PoW-style "mining" output, and the network's energy consumption has dropped drastically.
