+# Cipher ParaTime
+
+Cipher is a confidential ParaTime for executing Wasm smart contracts.
+
+As an officially supported ParaTime by the Oasis Protocol Foundation, Cipher
+allows for:
+
+* Flexibility: developer can define which data to store in a public
+  and which data in the (more expensive) confidential storage
+* Security: the [Rust language] primarily used for writing Wasm smart contracts
+  is known for its strict memory management and was developed specifically to
+  avoid memory leaks
+* Scalability: increased throughput of transactions
+* Low-cost: 99%+ lower fees than Ethereum
+* 6 second finality (1 block)
+* Cross-chain bridge to enable cross-chain interoperability (upcoming)
+
+If you're looking for EVM-compatible ParaTimes, check out the
+[Emerald](../emerald/README.mdx) and the confidential
+[Sapphire](https://github.com/oasisprotocol/sapphire-paratime/blob/main/docs/README.mdx) paratimes.
