As a new generation of public chain, Super Gold proposes its own innovation on the basis of absorbing the advantages of previous public chains. Considering that the DBFT consensus mechanism has unique advantages in solving the low scalability, low concurrency, and low transaction feedback of the public chain, and has achieved practical results, the way Super Gold’s cryptocurrency SPG is produced tends to be more decentralized Therefore, Super Gold creatively combines the transaction verification under the DBFT consensus mechanism with the classic and stable workload proof algorithm Ethash, and separates the synchronization of transaction verification and block packaging to more It can well solve the problems of low scalability, low concurrency, low transaction feedback and block congestion of the blockchain. At the same time, Super Gold's smart contract system is more suitable for the current status and trends of blockchain technology development. The cross-chain protocol has great impact on cross-chain transactions. With the support, it is possible to create a public chain platform with higher universality, wider application range, and more prosperous and stable ecology.
