As the new generation of public blockchain, Super Gold builds upon the strengths of previous public chains while introducing its own innovations. Considering the unique advantages of the Delegated Byzantine Fault Tolerance (DBFT) consensus mechanism in addressing the issues of low scalability, low concurrency, and poor transaction feedback on public blockchains, and given its practical achievements, the cryptocurrency SPG of Super Gold leans towards a more decentralized Proof-of-Work (PoW) mining production method. Thus, Super Gold innovatively combines the transaction verification under the DBFT consensus mechanism with the classic and stable Ethash work proof algorithm, decoupling transaction validation from block packaging to better solve the problems of low scalability, low concurrency, poor transaction feedback, and block congestion in blockchain technology. Meanwhile, Super Golds smart contract system is more suitable for the current status and trends of blockchain technology development. The cross-chain protocols support for cross-chain transactions enables the creation of a public blockchain platform with higher universality, broader application scope, and a more prosperous and stable ecosystem.
