Ripple is the catchall name for the cryptocurrency platform, the transactional protocol for which is actually XRP, in the same fashion as Ethereum is the name for the platform that facilitates trades in Ether. Like other cryptocurrencies, Ripple is built atop the idea of a distributed ledger network which requires various parties to participate in validating transactions, rather than any singular centralized authority. That facilitates transactions all over the world, and transfer fees are far cheaper than the likes of bitcoin. Unlike other cryptocurrencies, XRP transfers are effectively immediate, requiring no typical confirmation time. Ripple was originally founded by a single company, Ripple Labs, and continues to be backed by it, rather than the larger network of developers that continue bitcoin’s development. It also doesn’t have a fluctuating amount of its currency in existence. Where bitcoin has a continually growing pool with an eventual maximum, and Ethereum theoretically has no limit, Ripple was created with all of its 100 billion XRP tokens right out of the gate. That number is maintained with no mining and most of the tokens are owned and held by Ripple Labs itself — around 60 billion at the latest count. Even at the recently reduced value of around half a dollar per XRP, that means Ripple Labs is currently sitting on around $20 billion worth of the cryptocurrency (note: Ripple’s price crashed hard recently, and may be worth far less than $60 billion by time you read this). It holds 55 billion XRP in an escrow account, which allows it to sell up to a billion per month if it so chooses in order to fund new projects and acquisitions. Selling such an amount would likely have a drastic effect on the cryptocurrency’s value, and isn’t something Ripple Labs plans to do anytime soon. In actuality, Ripple Labs is looking to leverage the technology behind XRP to allow for faster banking transactions around the world. While Bitcoin and other cryptocurrencies are built on the idea of separating financial transactions from the financial organizations of traditional currencies, Ripple is almost the opposite in every sense.

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
