# Flashblocks 기능 지원

> 공지일자: 2025년 12월 9일
>
> 적용 네트워크: GIWA 테스트넷 (Sepolia)

GIWA Chain에 Flashblocks 기능이 새롭게 도입되었어요.

Flashblocks는 블록이 생성될 때까지 기다리지 않고, 트랜잭션에 대한 preconfirmation 신호를 빠르게 받을 수 있는 기능입니다. 이를 통해 트랜잭션 전송 후 수백 밀리초 (최대 약 200ms) 내에 빠른 피드백을 받을 수 있어 지갑, 결제 서비스, 게임 등 실시간성이 중요한 앱에서 더욱 증진된 사용자 경험을 제공할 수 있습니다.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.giwa.io/notices/giwa-chain/flashblocks.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
