As a new generation of public chains, Super Gold proposes its own innovation based on 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, Super Gold's cryptocurrency SPG is biased towards the mining and output mode under the more decentralized proof-of-work mechanism in terms of production mode, so Super Gold creatively combines the transaction verification under the DBFT consensus mechanism with the classic and stable proof-of-work algorithm Ethash, The synchronization of transaction verification and block packaging has been separated to better solve the problems of low scalability, low concurrency, low transaction feedback, and block congestion in blockchain. At the same time, Super Gold's smart contract system is more suitable for the current status and trend of blockchain technology development. The support of cross chain protocols for cross chain transactions can create a public chain platform with higher universality, wider application range, and more prosperous and stable ecology....
