"The SASEUL development team started developing the mainnet in 2017 and launched commercially in May 2022. The combination of the PoW consensus algorithm and its own PoR algorithm, HAP-2 (Hypothesis Acceptance Protocol), enabled decentralization and a dramatic improvement in speed. By adopting the Merkle Tree method, which allows selective storage of data at nodes, they have developed a new storage solution to handle fast TPS and enable data reliability and efficient operation of storage space. Unlike other layer 2 solutions, the SASEUL mainnet applies a separate consensus algorithm that operates the main chain and the resource chain separately, allowing data validation to be performed quickly and efficiently. SASEUL allows you to store all types of digital files as blocks, including images, videos, documents, contracts, applications, and more. It also integrates DID technology into stored files so that only people with matching DIDs can access them, and as long as the SASEUL network is maintained, all data can be stored semi-permanently. "
