Ontology is a new high-performance public blockchain project & a distributed trust collaboration platform.It provides new high-performance public blockchains that include a series of complete distributed ledgers and smart contract systems. Ontology is a blockchain framework supports public blockchain systems and is able to customize different public blockchains for different applications. It also supports collaboration amongst chain networks with its various protocol groups.They will constantly provide common modules on the underlying infrastructure for different kinds of distributed scenarios, such as those for the distributed digital identity framework, distributed data exchange protocol, and so on. Ontology was created in 2017 by a Chinese company called OnChain, which is led by founders Erik Zhang and Da HongFei. OnChain has had huge success in the cryptocurrency industry, as they were also the founders behind the NEO blockchain, which is now a multi-billion dollar project. Essentially, Ontology was created as a way for businesses of all sizes to install blockchain technology within their company, without having to completely change all of their current systems. The purpose of the Ontology framework is that it is not intended to operate as a single blockchain. Instead, the technology will allow businesses to make full use of both a private and public blockchain. Each and every data transaction is confirmed in a decentralized environment, meaning that no single person or authority can take control of the network.
The key to Space Chain is to deploy all blockchain nodes on satellites so as to bring blockchain technology into space, adding a new dimension to blockchain’s core concept of distributed ledger by making use of space technology and advantages of space resources. As a space blockchain platform featuring data collecting, computing, application and storage, Space Chain uses satellites as its blockchain nodes for realizing direct on-satellite data processing and secure in-space data storage through cryptographic technologies such as quantum communications. Different from ground-network-based blockchain technology, Space chain provides a broader coverage and is based on a network of LEO satellites for achieving broad-based connectivity so that anyone and anything could become the user of blockchain technology anywhere and anytime.
