The Peercoin network activated in 2012 and is one of the first cryptocurrencies to ever be released. It is responsible for inventing proof-of-stake consensus, which makes it the first efficient and sustainable public blockchain technology. Peercoin was inspired by bitcoin, and it shares much of the source code and technical implementation of bitcoin. The Peercoin source code is distributed under the MIT/X11 software license. Unlike bitcoin, Namecoin, and Litecoin, Peercoin does not have a hard limit on the number of possible coins, but is designed to eventually attain an annual inflation rate of 1%. There is a deflationary aspect to Peercoin as the transaction fee of 0.01 PPC/kb paid to the network is destroyed. This feature, along with increased energy efficiency, aim to allow for greater long-term scalability. With the same encryption algorithm as Bitcoin (SHA-256), Peercoin is 100 times more energy efficient. Transactions in the Peercoin network are faster and cheaper. If there were not fierce competition on the cryptocurrency market, Peercoin would probably have long since become one of the most important cryptocurrencies. But in 2014 and 2015, however, there were many other interesting innovations in the cryptocurrency market that outperformed peercoin in a number of important properties. In contrast to DASH, Peercoin could not offer anonymity and the transactions in Dogecoin were even faster and cheaper than those of Peercoin. PoS technology ceased to be an advantage of peercoin and PoS continued to spread to other cryptocurrencies. The interest of the users drew it to the side of the minings on the CPUs and GPUs, then to the side of the Smart Contracts and PPC began to get a little forgotten. The Peercoin Team believes that adapting blockchains for wide scale use only through on-chain transactions will negatively affect the decentralization level and security of the network over time, therefore we choose to develop the Peercoin blockchain as a base layer settlement network with a sole focus on securing all forms of value recorded into the chain. This can be accomplished through Peercoin's philosophy of preserving and maximizing decentralization (which increases security) by developing the majority of features and technologies on top of the blockchain, rather than directly into the blockchain protocol itself. Thus the Peercoin Team focuses on developing second layer protocols and sub-networks that can interact with the base layer blockchain to adapt it for wide scale use and improve functionality such as tokens, smart contracts and high speed low cost transaction processing. In this way, Peercoin will act as a secure and censorship resistant base layer for the future blockchain connected world.
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.
