On November 21, Sign, a sovereign digital infrastructure service provider, announced the launch of "Sign Sovereign Layer 2 Stack". Built on BNB Chain and opBNB Stack, this solution aims to assist governments in rapidly deploying secure and 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, possessing the following four core characteristics:
Digitalization of National Assets: Supports the tokenization and on-chain management of real-world assets (RWA) such as government bonds, land registrations, and natural resources;
Optimized stablecoin solutions: Provides gas-free stablecoin transfers, flexible fee waiver policies, and a scalable distribution system;
Native access control: Implement transaction interception and compliance control based on the government's dynamic sanctions list directly at the sequencer level;
DID Ecosystem Integration: Built-in native proof and decentralized identity (DID) solutions support identity-based application development.
Sign stated that the architecture allows governments to retain sovereign control over transaction processing while leveraging the ecosystem liquidity of BNB Chain, aiming to establish BNB Chain as the preferred settlement layer for global sovereign infrastructure and stablecoins.
