# Introduction to SEDA

## What is SEDA?

SEDA is a programmable oracle infrastructure that enables builders to access any data from any public or private source, in one unified platform across any blockchain.

## Technical Overview

**SEDA Layer One**\
\
SEDA is a layer one blockchain that serves the purpose of a read-write network where developers can deploy, store, and access Oracle Programs and Data Proxies. \
\
**Oracle Programs**\
\
SEDA Oracle Programs are programmable, deterministic, verifiable computation modules that can fetch any public or private external data source off-chain or onchain, apply custom logic, and deliver structured outputs either onchain or with ultra-low-latency API/WebSocket connections.\
\
**Data Proxies**\
\
A Data proxy is a simple middleware component that acts as a pipeline or connector between any API  and SEDA by holding an API key that has access to the data provider’s services.
