The Stellar network is an open source, distributed, and community owned network used to facilitate cross-asset transfers of value. Stellar aims to help facilitate cross-asset transfer of value at a fraction of a penny while aiming to be an open financial system that gives people of all income levels access to low-cost financial services. Stellar can handle exchanges between fiat-based currencies and between cryptocurrencies. Stellar.org, the organization that supports Stellar, is centralized like XRP and meant to handle cross platform transactions and micro transactions like XRP. However, unlike Ripple, Stellar.org is non-profit and their platform itself is open source and decentralized. Stellar was founded by Jed McCaleb in 2014. Jed McCaleb is also the founder of Mt. Gox and co-founder of Ripple, launched the network system Stellar with former lawyer Joyce Kim. Stellar is also a payment technology that aims to connect financial institutions and drastically reduce the cost and time required for cross-border transfers. In fact, both payment networks used the same protocol initially. Distributed Exchange Through the use of its intermediary currency Lumens (XLM), a user can send any currency that they own to anyone else in a different currency. For instance, if Joe wanted to send USD to Mary using her EUR, an offer is submitted to the distributed exchange selling USD for EUR. This submitted offer forms is known as an order book. The network will use the order book to find the best exchange rate for the transaction in-order to minimize the fee paid by a user. This multi-currency transaction is possible because of 'Anchors'. Anchors are trusted entities that hold people’s deposits and can issue credit. In essence, Anchors serves as the bridge between different currencies and the Stellar network. Lumens (XLM) Lumens are the native asset (digital currency) that exist on the Stellar network that helps to facilitate multi-currency transactions and prevent spams. For multi-currency transactions, XLM is the digital intermediary that allows for such a transaction to occur at a low cost. In-order to prevent DoS attacks (aka spams) that would inevitably occur on the Stellar network, a small fee of 0.00001 XLM is associated with every transaction that occurs on the network. This fee is small enough so it does not significantly affect the cost of transaction, but large enough so it dissuades bad actors from spamming the network. The collected fee is then redistributed and added to an inflation pool. This inflation pool releases Lumens at a rate of 1% each year.
Aave is a decentralized lending platform that runs on Ethereum Network which offers secure, peer-to-peer lending Smart Contracts. Aave strives to break through the traditional bank loans system with a more efficient solution. Aave also uniquely allows a borrower and a lender to decide on important loan details that can eliminate the need of a middle man. Due to the elimination of middlemen, process fee for a loan does not exist on this platform. This provide convenience to any lender and borrower to create loans on their agreed terms. Decentralized lending has fixed many issues and one of the reasons why is the transparency of loan. The Ethereum network provides a transparent ledger where all transactions are available to be inspected. Secondly, it isn’t necessary to find a trusted loan provider because all collateral which is the digital asset for loans are stored and locked in a smart contract and broadcasted on the public ethereum blockchain. It is also flexible for borrower to manage the collateral by refilling or withdrawing part of it. Borrower may make such changes when the lender is notified and aware of such movement. If the lender finds out that the action is not communicated, the lender is allowed to initiate a margin call. This year, Aave has made a major upgrades in its Q1 2018. They have deployed the new development for their peer-to-peer lending application named Alpha 0.3. The development process of Alpha 0.3 has started since the early of 2017. The new release also includes a completely new user interface which targets to lower the learning curve of user experience on the app. Furthermore, the new user interface has new sections to make lending process simpler such as including a ‘My Loan’ section, collectible badges and more. Other than that, the team is also in the process of developing more updates for the smart contracts. Hence, the team has decided to provide zero-fee lending with the use of LEND token as a medium of exchange, as an alternative to borrowing in Ethereum. The purpose of this is to provide a cross-blockchain lending currency which will prompt users to use LEND as the medium of exchange.
