Cipher ParaTime

The Cipher ParaTime is a Confidential ParaTime for executing Wasm smart contracts.

As the 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 — 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
  • Cross-chain bridge to enable cross-chain interoperability (upcoming)

If you're looking for EVM-compatible ParaTimes, check out the Emerald and the confidential Sapphire paratimes.

Smart Contracts Development

The Cipher ParaTime implements the Oasis Contract SDK API. To learn how to write a confidential smart contract in Rust and deploy it on the Oasis Cipher ParaTime, read the related Oasis Contract SDK chapters:
