# Privacy
> Unlock private, verifiable computation
#### 🔴 Problems with Privacy
* **Data Exposure** – Sensitive information is on the public ledger.
* **Centralized Trust** – Users must trust third parties with their private data.
* **Lack of Verifiability** – No way to prove computations were performed correctly without revealing data.
#### ⛓️ Current Blockchain Limitations
* **Public Execution** – All transactions and smart contract state are visible on-chain.
* **MEV Exploitation** – Front-running and sandwich attacks exploit transaction visibility.
* **Compliance Barriers** – Regulatory requirements often conflict with public transparency.
#### ⚡ MagicBlock's Solution
* **Trusted Execution Environments (TEEs)** on Intel TDX – Secure, isolated computing environments that protect data during processing.
* **Private State Execution** – Run computations on sensitive data without exposing it to the network.
* **Verifiable Privacy** – Cryptographic proofs ensure correct execution while maintaining confidentiality.
