Loopring is an open protocol for building decentralized exchanges. Loopring has quickly gained visibility as one of the decentralized exchange options that’s making progress on trading across multiple blockchains. Loopring’s solution utilizes ring transactions and order matching to facilitate asset exchanges. Essentially, it aggregates the order books of other exchanges. This allows any exchange, decentralized or centralized, to utilize Loopring’s protocol to match orders. Part of providing an open protocol is remaining blockchain agnostic. Hence, the first Loopring token (LRC) was launched on Ethereum, but it also plans to launch Loopring NEO (LRN) and Loopring QTUM (LRQ). The plans to launch Loopring NEO are coming along. The distribution of the new tokens, LRN, has already begun. Essentially, the token distribution involves two phases: an investor sale and an airdrop. This guide will look at both phases, how to buy LRN, and what to expect from Loopring NEO. The big selling point of Loopring’s exchange solution is you never have to deposit funds to Loopring. With most exchanges, even other decentralized exchanges, you still have to transfer funds to their wallets. On Loopring, you can keep your funds in your own private wallet when trading. Of course, that creates a challenge for Loopring because the exchange no longer controls the wallet and that means smart contracts need to do the work of verifying that transactions are legitimate and confirmed. When a trade occurs, it happens user to user, with no middleman. Loopring finds the match and coordinates the terms of the trade, but it never controls the assets. Loopring is one of the first projects to attempt launching across multiple blockchain ecosystems. This experiment is interesting and exciting. It also has the potential to be lucrative if Loopring continues to increase in value.
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
