A data trading platform for diverse businesses and industries was launched in Singapore in October. The main-net was finished in August of 2019. OASISBloc has an inter-chain that connects the domain chain of each industry. Interconnection of user accounts, data transaction history, and domain chain history are recorded and managed through OASISBloc, which turns data generated by each user into a standardized and valuable data. OASISBloc has a witness group that consists of 39 candidates for block generators, and each level of the witness group selects the final block generator at random. Every time there is a transaction of data trading, block generators generate and verify blocks for a swift and accurate recording on block.
