According to its whitepaper, Aeron aims to be the new standard of aviation safety powered by the blockchain. Maintained by a group of aviation professionals, Aeron wants to reduce air transport-related accidents, which it says currently numbers around 3302 per year. One of the major causes of such accidents is the lack of real experience among pilots, since unsecured flight log data from them is susceptible to fraud and forgery. Also, due to 'pay to fly' experiences, corrupt flight schools, negligence of aircraft operators, the primary data driving any decision is affected. Aeron is built upon a robust and cryptographically secure database that makes it unique compared to other online travel companies, travel search services or internal applications made for flight officials. With this technology, falsification of data can be kept at a minimum. Additionally, as you would expect from a blockchain-backed application, key information is safely stored and is accessible to everyone with 100% transparency. Except that it now comes secured by a multi-sig authentication system that prevents any type of security breach. According to Aeron's Whitepaper, 'The pilot’s application is used by a pilot for personal flight logging. The company application collects and verifies data from aircraft operators, maintenance organizations, flight schools and fixed base operators'. Aeron (ARN) is an ERC20 compliant Ethereum based token, with a fixed supply of 20,000,000 ARN. When the token was launched, a fixed amount of tokens were created and after which no more tokens are to be minted. About 60% of the supply is estimated to be in circulation. The supply should decrease over time when ARN tokens as taken out of circulation. Once Aeron receives ARN tokens in exchange of services, the coins will be again released in to the network. According to its whitepaper, Aeron plans to have a user base of 300000 by the end of 2020. This would encourage it to embed new features on its platform. With the help of multi-app functionality and block technology, the company envisions to have an “airline in the pocket” of sorts within two years. While its price has fluctuated like most other cryptocurrencies, it delivered more than 15x returns within a short period between November 2017 to January 2018. As of July 2018, the price is nearly back to its November levels, at $0.57.
PIVX stands for Private Instant Verified Transaction. PIVX is an MIT licensed anonymity-based cryptocurrency created out of a fork of DASH. PIVX is an open source blockchain-based Proof of Stake cryptocurrency with Zerocoin protocol implementation for industry leading transaction privacy. PIVX project is focused on advancing its privacy technology to ensure fungibility, improve network scalability and increase real-world utilization to become an effective decentralized online digital currency for everyone. PIVX inherited all the technical features of DASH such as masternodes, instant send and private transfer. It has a block time of 60 seconds and has a fixed reward size per block that uses a custom Seesaw Algorithm that dynamically alters the reward split between masternode and staking nodes. PIVX also utilizes a decentralized network of masternodes that allow feature services, treasury management, and community governance. The project is focused on advancing its privacy technology to ensure fungibility, improving network scalability, and increasing real-world utilization to become a globally-accepted decentralized online digital currency. PIVX is the first cryptocurrency to implement a directly spendable Zerocoin protocol and has also developed and implemented an industry-first Zerocoin-capable Proof of Stake consensus algorithm, called zPoS, that allows complete privacy of the balance and transactions while staking. PIVX “wallet” software closely resembles running your own bank, while basecoin (PIV) for transparent transactions and Zerocoin (zPIV) for completely anonymous, untraceable transactions. PIVX is an advanced privacy-enabled proof-of-stake cryptocurrency using the Zerocoin Protocol, an advanced zero-knowledge-proof privacy protocol for utmost transaction anonymity, and zPoS, a world’s first privacy-enabled Proof of Stake technology all developed by a team of highly experienced developers and cryptographers. Here at PIVX, we wanted to do something innovative, so we brought this cutting-edge technology to life. PIVX is available to be purchased directly with some popular fiat currencies. Here are some exchanges that provide the option to buy PIVX with currencies (USD, EUR etc.) UpBit, Coinroom, LiteBit. The PIVX network allows for 2.6 million PIVX tokens to be minted per year forever, with 90% of the minted coins going to staking wallets and Masternodes (staking is covered in the next section), and 10% going to fund budget proposals voted on by the Masternodes and stakers. This lack of a maximum coin supply makes PIVX function similar to a traditional currency, as inflation is introduced to the system to encourage daily usage and avoid hoarding. The inflation is around 4% per year, but instead of simply devaluing your currency like the Fed does when it prints Dollars, all those minted coins are going directly to holders of PIVX, offsetting the effect of inflation by spreading the profits. PIVX is a promising privacy coin aiming to be an easy-to-use digital cash replacement. There have been a few hiccups surrounding the implementation of the privacy technology, but the community and development team are active, engaged, and optimistic. It’s performing well on the market, with high volume and support from major exchanges (most notably Bittrex) and looks like it’ll be around for a while.'
