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.
Ankr strives to build a resource efficient blockchain framework that truly enables Distributed Cloud Computing (DCC) and provides user-friendly infrastucture for business applications. There are indeed existing cloud solutions, but Ankr is the first one to leverage both blockchain and trusted hardware. Technology Overview Ankr provides a computation-resource-efficient blockchain and an integrated data feed system leveraging both cryptographic primitives and trusted hardware Proof of Useful Work The Proof of Useful Work (PoUW) consensus enables a self-sustainable blockchain framework. Instead of wasting electricity and computing power on hashes like Bitcoin does, PoUW uses these resources towards useful work tasks provided by enterprises and consumers. The protocol runs on SGX-enabled CPUs with remote attestation to ensure security and confidentiality. The novel PoUW approach unlocks the massive potential of idle computing power around the world by providing enough incentives: in this scheme, every computation contributor gets compensated, and some will get the extra reward for generating the blocks. In the future, this mining scheme can promote Universal Basic Income (UBI). Plasma Sidechains The Multi-chain Plasma implementation allows different applications to handle application-specific smart contracts on individual side chains, preventing transactions from overloading the PoUW-based main chain. Native Oracle Service Native Oracle Service (NOS) provides authenticated data feed by leveraging both cryptographic primitives and the trusted execution environment (TEE). Through a standardized API to port data from existing websites, NOS enables simple real-world business adoption
