BlockBeats News, November 21st, Sovereign digital infrastructure service provider Sign announced the launch of the "Sign Sovereign Layer 2 Stack." This solution is built on the BNB Chain and opBNB Stack, aiming to assist governments in rapidly deploying secure, compliant national stablecoins and sovereign blockchain infrastructure within weeks.

The Sign Sovereign Layer 2 Stack combines the high performance of opBNB with the liquidity of the BNB Chain and features the following four core characteristics:

National Asset Digitization: Supports the tokenization and on-chain management of real-world assets (RWA) such as government bonds, land registration, natural resources, etc.;

Optimized Stablecoin Solution: Provides gas-less stablecoin transfers, flexible fee waiver policies, and a scalable distribution system;

Native Permission Control: Directly implements transaction interception and compliance control based on government dynamic sanctions lists at the Sequencer level;

DID Ecosystem Integration: Built-in native proofs and decentralized identity (DID) solutions to support identity-based application development.

Sign stated that this architecture allows governments to retain sovereign control over transaction processing while leveraging the liquidity of the BNB Chain, aiming to establish the BNB Chain as the preferred settlement layer for global sovereign infrastructure and stablecoins.
