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.
Harmony’s open, decentralized network is enabled through the use of the native protocol token - Harmony ONE. The token incentivizes and rewards a variety of participants including developers, validators/stakers, investors, and community members who develop, secure and govern the network. In order to use the network, users pay a small transaction fee denominated in the native Harmony token. Harmony’s scalable, high-throughput protocol is powered by a native token which is used for various forms of payment and participation in the protocol (staking, transaction fees, voting & governance). Harmony uses blockchain to align incentives of different stakeholders, developers and businesses while allowing them to build open marketplaces of fungible and non-fungible tokens and assets. Furthermore, the upcoming application of zero-knowledge proofs will allow Harmony to become a data sharing platform that can overcome the conflicting problem plaguing many information and data markets: that individual market participants’ have mutual distrust to share data but strong desire to acquire data themselves. The Harmony token will function in the following aspects of the protocol: The token is used for staking, which is necessary to participate in the POS consensus & earn block rewards and transaction fees. The token is used to pay for transaction fees, gas and storage fees. The token is used in voting for on-chain governance of the protocol.
