AdEx (ADX) stands for “advertising exchange.” AdEx Coin is a blockchain-based marketplace for ads that aims to change the existing online advertising landscape and solve its major problems: ad fraud, privacy and consent to receive sponsored messages, etc. AdEx is fully transparent and built on the Ethereum Smart Contracts. AdEx is still in development, so it’s difficult to say much yet about it at this point. The original roadmap anticipated a beta release in February 2018. It remains to be seen if the team will meet that deadline. Future plans for version two of AdEx after launch focus on improving the user experience and scalability. AdEx has also expressed an interest in implementing a real-time bidding solution that could take place off-chain or on a high throughput network, like IOTA. AdEx raised $10 million in the first three hours of token sale. AdEx as a platform has room for a good amount of growth since digital advertising is a booming business anyway. But by eliminating flaws and continuing updates on its current platform, AdEx aims to stand firm in the near future.
Solarcoin is a Scrypt based alternative digital currency and its innovation comes from the secondary proof of work reward: the Solar Proof of Work. Green solar energy producers are entitled to receive one SLR for every MWh electricity generated. In order to claim a Solar Proof of Work reward, solar plant owners must submit 3rd party verified energy generation certificates such as a Solar Renewable Energy Certificate (SREC) or equivalent country specific documentation. All Solar Proof Of Work rewards will be stored as transactions in the blockchain. The supply of SLR comprises of the following: - The Mining Pool: 105 million Solarcoins (0.1%) to be publicly mined over the next 40 years. All publicly mined Solarcoins represent historically generated and unclaimed solar electricity. - The Generator Pool: 97.5 billion SolarCoins (99.4%) are currently stored in the OCA non-circulating generation pool account. These will be exchanged for Solar Proof of Work claims of solar electricity generation submitted over the next 40 years at the rate of 1 SLR per MWh of solar energy. - The Genesis Pool: 500 million Solarcoins (0.5%) are stored in the genesis pool account for environmental charities, early volunteers, advisers, builders and maintainers of SolarCoin infrastructure. Genesis pool circulation is capped so that it will never represent more than 5% of total Solarcoin in circulation.
