Our distributed social mainnet is based on Graphene toolkit (Graphene Toolkit Technology) and using the in-house built algorithm DDPoS, we solve the existing problem of speed in PoW and security problem of DPoS.
Differences in the verification method result in differences in block creation and transaction speed. The PoW method processes 7 ~ 10,000 transactions per second. Therefore, it is difficult to apply it to the actual service due to the processing speed problem.
As a result, existing PoW makers are making various attempts to increase the speed, but are still within the limits of the original model.The DPoS method handles 100,000 transactions per second, but our DDPoS method performs 300,000 transactions per second and generates blocks every three seconds, making it suitable for service and excellent in stability.
At Sigma Chain, we have further enhanced the security of DPoS algorithm. It consists of 17 BPs (Block Provider) which are pre-determined and 4 randomly selected BOs (Block Observer), totaling 21 nodes. The existing DPoS model is subjected to hacking with 21 pre-determined nodes, but with DDPoS, it is even more difficult to hack with the addition of random 4 nodes. Sigma Chain has named this model as DDPoS (Dual DPOS) and has filed patents worldwide.
Sigma Chain's independent mainnet enables transaction processing and free ecosystem configuration and provides Web/App wallet generation and a stable service.
In order to enhance the stability of DApps, we have deployed various access methods depending on the different activities of DApp users. (posting, commenting, coin transfer, etc.)
Sigma Chain provides the ability to monitor the results of block generation for block generating nodes based on Web services. Also, by providing development debug nodes for engine improvement without registering with the blockchain service network, the Sigma Chain mainnet monitors the blockchain network situation and enables separate development from the current blockchain service.
It has been developed to easily change the number of cases, including the number of participants and the number of velidators. So, it's easy and reliable when banks or businesses attempt to deploy a block chain internally.
The Sigma Chain provides a stable system with guarantined performance through DDPoS - a complex and difficult blockchain algorithm, to ensure optimal performance even in typical PC environments.
