#Gas费影响 ## Gas fee: a double-edged sword of Ethereum ecosystem

Gas fee is the handling fee of Ethereum network, which is used to incentivize miners to process transactions and execute smart contracts. The level of Gas fee directly affects the user experience and ecological development.

**Negative impact of excessively high Gas fee:**

* **Hindering user participation:** High Gas fee will exclude ordinary users and limit the large-scale popularization of applications such as DeFi and NFT.

* **Inhibiting innovation:** Developers need to consider the cost of Gas fee and may give up some complex but innovative application designs.

* **Increasing network congestion:** In order to confirm transactions as soon as possible, users will increase Gas fee, forming a vicious circle.

**Solutions to reduce Gas fee:**

* **Layer 2 expansion:** Transfer transactions to off-chain processing to reduce the pressure on the main network, such as Optimism, Arbitrum, etc.

* **Sharding technology:** Divide the network into multiple shards, process transactions in parallel, and increase throughput.

* **EIP-1559 Proposal:** Introducing basic fees and destruction mechanisms to make gas fees more predictable and reasonable.

Gas fees are a challenge that the Ethereum ecosystem must face in its development. Only through technological innovation and community efforts can we build a more efficient and inclusive blockchain network.
