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
PolySwarm in 60 Seconds. Polyswarm is a decentralized threat intelligence market made possible by Ethereum smart contracts and blockchain technology. Polyswarm incentivizes rapid innovation in the $8.5B/yr anti-virus and automated cyber threat intelligence space with precise economic incentives that reward timely and accurate threat intelligence concerning the malintent of files, network traffic and URLs. PolySwarm defines a real-time threat detection ecosystem involving enterprises, consumers, vendors and geographically-diverse security experts. Experts develop and hone competing “micro-engines” that autonomously investigate the latest threats, attempting to outperform their competition. PolySwarm’s “Proof of Work” is threat detection accuracy: the market rewards experts who are best able to defend enterprises and end users. Relative to today’s ad hoc market, PolySwarm will lower the barier to entry, provide broader coverage options, discourage duplicative effort and ensure interoperability among products and threat intelligence feeds. Economically, PolySwarm functions as a skill-required twist on a prediction market2 with thousands of micro-engines (“workers”) investigating the latest in malware evolution at machine speed - no human in the loop. PolySwarm will be developed by Swarm Technologies, Inc. (“Swarm Technologies”) with funding derived from the sale of ERC20-compatible Nectar (“NCT”) utility tokens. As a utility token, PolySwarm economically disincentivizes Nectar speculation by rewarding honest market participation through the collection and distribution of Fees (details on page 6) to valueadding, active participants.
