On Thursday, the Sui Foundation announced via a blog post that Seal now supports a Decentralized Key Server that distributes trust across multiple independent operators using threshold cryptography. This ensures that no single party ever holds a complete key.
Membership can rotate over time without re-encrypting existing data, keeping public keys and onchain policies stable as infrastructure evolves. Integration requires minimal changes: same SDK, same encryption flows, same Move policies, just a new server type to configure.
Seal is Sui’s programmable encryption layer, letting developers define onchain policies for who can access encrypted data, without relying on a centralized service to manage keys.
The Decentralized Seal Key Server, powered by multi-party computation (MPC), embeds distributed key trust directly into the infrastructure layer. To applications, it looks like a single logical key server. Internally, it enforces threshold cryptography across multiple independent operators. Developers can gain stronger decentralization and smoother operator rotation, without changing how they build with Seal.
From your application’s perspective, a Decentralized Seal Key Server is simple. It exposes one onchain object ID, one public key, and one endpoint (via a trustless aggregator). Developers configure it like any other Seal key server, and their policies and encryption flows remain unchanged.
