 IOTA stands apart as a scalable, feeless Distributed Ledger Technology (DLT), suitable for a universal identity solution. Some features of IOTA include:
 
-1. **Permissionless & Decentralized**: IOTA ensures neutrality and resists censorship, as every participant is an integral part of the consensus.
-2. **Public**: IOTA's transparent nature ensures every transaction on the network is observable.
-3. **Feeless**: Both data and value transactions on IOTA's network are free of cost.
-4. **Open Source**: IOTA's codebase is publicly accessible and open to contributions.
-5. **Ease of use**: IOTA Identity is user-friendly and secure, thanks to its integration with the [Stronghold](/stronghold.rs/welcome) project.
+* **Cost-effectiveness**: Usually, minting decentralized identities costs fees. IOTA Identity has redeemable and predictable deposits but no fees.
+* **High availability**: Identities are always available on all network nodes - for holders, issuers, and verifiers.
+* **Security**: Write access to identities is secured through multi-level control structures with key rotation capabilities, allowing for backup access and recoverability.
+* **Integrity**: Updates go through the same mechanisms that secure the IOTA network, guaranteeing consistent state and history of all identities.
