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.
Steem is a cryptocurrency that rewards users for community building by posting and upvoting valuable content for others. Steem was inspired from the success of Reddit where the community helped enrich the shareholders. Steem aims to help distribute the rewards to the community members who help create the community in the first place. Steem aims to provide various services to its members such as a source of curated news, Q&A, job boards etc. The founders of Steem came from BitShares with Dan Larimer involved as well. Steem’s main platform, called Steemit, is a social media network built on top of the Steem blockchain. Steemit is similar to popular content-driven social networks like Reddit and Medium, but it rewards users with cryptocurrency for their participation. Fundamentally, the more value a particular piece of content provides to a greater number of people, the more the individuals responsible for creating and curating that content can earn. Users cast votes, creating a hierarchy of content. The more upvotes a post gets, the more it will earn. The platform also allows for downvotes, giving participants more flexibility when it comes to rating content. Steemit is meritocratic, meaning users that hold more currency can cast votes with greater influence. The Steemit community even has another service to offer to its customers. D.tube, which is considered to be very similar to YouTube, is Blockchain based and the users can realize the difference between the traditional video publishing websites and D.tube, as the amount of money earned is also displayed beside the post apart from likes shares and comments. The Steemit community is accused of posting plagiarize contents on their publishing website. The irony seems to be reaching highest levels when the original content doesn’t receive much appreciation and income than the copied versions of it.'
