Strong, effective, and efficient cryptography comprises a core pillar of #Sui.

Let’s dive into the first blog post in the #Cryptography in Sui series, which takes a look at best practices and why Sui supports certain algorithms and primitives.

🧵[1/7]

As a core pillar of Sui cryptography, we created fastcrypto, a library published as an independent #Move crate making it easy for developers to implement strong security across their applications.

The reference Sui Wallet and Typescript SDK share the same cryptography backend utility implementations, ensuring standardization and common cryptographic implementation.

Along with the Rust SDK, devs can use the reference Sui Wallet implementation and toolkits for integration.

Sui’s inherent crypto agility means it can accept more than one type of user signature scheme, and Sui can switch validator consensus signature schemes rapidly. This design also enables system level benchmarking for observability.

Cryptographic primitives on-chain in Move are implemented with these considerations:

🔹Standard in the blockchain ecosystem
🔹Enable cross-chain + off-chain applications
🔹Enable new applications that utilize Sui as a highly performant blockchain
🔹Enable innovation in general

Sui is being developed with the best practices in cryptography described above and provides toolings to help developers build applications that give users the safest experience.

Future blog posts in the Cryptography series will cover such topics as wallet specifications, cryptography agility, crypto primitives, and benchmarking cryptographic libraries.

The goal is to inform the Sui community while helping developers build the most secure applications.
