# Key functions

The ivault Chain is crucial for storing and securing user data, supporting a host of functions in the ivault app.

1. **Secure data storage**: The ivault Chain acts as a distributed ledger, creating an immutable track record of transactions and activities on the blockchain. This means no one can hack or manipulate the data.
2. **Encrypting and protecting user data**: details about items, transaction history, ratings and other data is stored securely on the blockchain, safeguarding user privacy.
3. **Secure transactions**: records peer-to-peer transactions on the blockchain and users have a record for their payments.
4. **Genuine ratings and reviews**: no more fake feedback. ivault’s ratings and reviews are anchored to verified transactions recorded on the blockchain, so users can trust their authenticity. 
5. **Seamless experiences**: securely automate escrow services and transactions using smart contracts. For example, releasing funds after an item has been dropped off, or even resolving disputes.
