OASISBloc Foundation, based in Singapore, launched OASISBloc, a data trading platform for diverse businesses and industries, in October 2018. The platform's main-net was completed in August 2019 after successfully developing MVP and test-net. In October 2020, OASISBloc released the latest version of its whitepaper (v.0.7.1) and business roadmap on their website. One of the key features of OASISBloc is its inter-chain, which connects the domain chain of each industry. User accounts, data transaction history, and domain chain history are all recorded and managed through OASISBloc, turning user-generated data into standardized and valuable data. With these features, OASISBloc participants can trade practical data for mutual benefits. Another key feature of OASISBloc is its self-developed ePoA (equitable Proof of Authority) consensus algorithm, designed to address the weaknesses of PoA where certain parties may have too much authority. OASISBloc has a witness group consisting of 39 candidates for block generators, organized into three levels. The final block generator is selected randomly from each level. Block generators ensure swift and accurate recording of data trading transactions, exchanging value between domain chains. OASISBloc's consensus algorithm, ePoA, maintains transparency in the block generation process and history, allowing anyone to experience the irreversibility of transactions and block validation.
