# Overview

> ## <mark style="color:purple;">What is TrustScan</mark>

As one of the core products of Trusta Labs, TrustScan, driven by data and AI, provides in-depth on-chain risk and reputation evaluation, characterization and authentication services for DID subjects in the Web3 world.

As we all know, on-chain data is open and transparent, but it is also original, detailed and factual. Such data records the on-chain behavior of each DID (such as wallet address), but it cannot provide insight into the deep, overall and implicit characteristics of the subject.

TrustScan aims to bridge the gap between the raw data on-chain and the need for insight into the characteristics of DID's reputation. With on-chain original data as input and AI(Artificial intelligence) technology as engine, we provide in-depth insight, analysis, evaluation and certification services for the reputation of DID subjects in the Web3 world, covering sybil attack risk, fraud risk, identity value, credit score etc. You can access the service of TrustScan via various methods, including API, UI based single-address query, and multi-address batch query.

There is a huge amount of public data on Web3 and blockchain, including wallet addresses, asset transfers, smart contract interactions, etc. How to efficiently process these original and detailed data, extract valuable information from them, and put these information into higher-level decentralized applications as new production factors? That is a huge opportunity but also a big challenge.

Trusta Labs uses trustworthy AI as core technology to analyze, mine and predict valuable results from massive and complicated original data, and form a series of services in TrustScan product matrix.

The core components of trustworthy AI in TrustScan include:

* Semi-supervise Machine Learning
