Sign Launches Sovereign Layer 2 Stack on BNB Chain to Support National Stablecoins and Infrastructure Development

BlockBeats News, November 21 – 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 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, featuring the following four core characteristics: - **Digitization of National Assets**: Supports the tokenization and on-chain management of real-world assets (RWA) such as government bonds, land registries, and natural resources. - **Optimized Stablecoin Solutions**: Offers gas-free stablecoin transfers, flexible fee exemption policies, and scalable distribution systems. - **Native Permission Control**: Implements transaction interception and compliance controls directly at the Sequencer level, based on government dynamic sanction lists. - **DID Ecosystem Integration**: Built-in native proof 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 ecosystem. The goal is to establish BNB Chain as the preferred settlement layer for global sovereign infrastructure and stablecoins.
