Sign has launched the Sovereign Layer 2 Stack (S.I.G.N) based on BNB Chain, positioned as a sovereign infrastructure solution for national-level deployments. It enables the rapid launch of stablecoins and digital services without the need to build a validator network, while allowing governments to control the Layer 2 sequencer to meet compliance and governance requirements. This architecture is built on BNB Smart Chain and the opBNB Stack, supporting various types of RWA such as tokenized government bonds, land registration, and natural resources. It facilitates stablecoin distribution, gas-free transfers, address permission control, and comes with built-in DID and a native authentication system to support identity-related applications. https://www.(wublock123.com)/index.php?m=content&c=index&a=show&catid=6&id=52227
