According to BlockBeats news, on November 21, sovereign digital infrastructure service provider Sign announced the launch of the “Sign Sovereign Layer 2 Stack.” This solution is built on BNB Chain and opBNB Stack, aiming to assist governments in quickly 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 BNB Chain and features 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 registration, and natural resources; Optimized stablecoin solutions: Provides gas-free stablecoin transfers, flexible fee exemption policies, and scalable distribution systems; 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 proof and decentralized identifier (DID) solutions, supporting identity-based application development. Sign stated that this architecture allows governments to retain sovereign control over transaction processing while leveraging the ecological liquidity of BNB Chain, aiming to establish BNB Chain as the preferred settlement layer for global sovereign infrastructure and stablecoins.
