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
NATIVE MULTICHAIN PLATFORM PCHAIN is the first native multichain system in the world that supports Ethereum Virtual Machine (EVM), which consists of one main chain and multiple derived chains. CONSENSUS WITH HIERARCHICAL SHARDING PIPELINE POS based multi layer sharding mechanism with a novel pipeline design that tremendously improves the performance of transactions. SMART CONTRACTS BASED ON SMART DATA A new Oracle mechanism based on the knowledge graph makes it easier to encapsulate smart contracts. W3C compliant smart data effectively adresses the issue of nonintelligence in smart contracts. CROSS CHAIN INVOCATION AND TRANSACTIONS The smart contracts of PCHAIN can be easily invoked with other nonnative Tokens (BCH, ERC20) by using the provided toolkit.
