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.
OriginTrail provides a helpful protocol solution to the problem of maintaining trust among all players involved in bringing a product to market by making the “chain” in “supply chain” more literal. Using blockchain technology, OriginTrail can append immutable data to products as they take each step along the supply route. Thus, each participant not only verifies that their conditions are being met but that at every previous stage, the right conditions were also met by everyone else. This is achieved by making an application layer that allows data to be collected in the real world, and then stored on the blockchain. OriginTrail started out by testing their tracking with organic beef products in 2014, and they are still mostly involved in the tracking of food products in general. It wasn’t until 2016 that they introduced a blockchain into their system. In January 2018, they raised US$22.5 million in their ICO. Since their ICO they’ve successfully launched their testnet, implemented privacy features, and achieved compliance with the GS1 standards that are integral to their business model. Their roadmap is robust and full of details, citing certifications with international bodies, alliances with companies, and entering new markets. Their mainnet is scheduled for launch in Q3 2018, and thereafter they appear to be on track to having all their services fully operational by 2020. OriginTrail is not the first or only company to recognize that supply chains could benefit a great deal from blockchain technology. Ambrosus is also going for the same market, though they seem to be focused on food and pharmaceuticals specifically. It should be noted that most supply chains have their own specific quirks, and so specialization might be be a good option. Another potential competitor of OriginTrail is Waltonchain, a company based in China that puts heavy emphasis on RFID chip scanning as part of their business model. In other words, where OriginTrail wants to leverage existing systems for their infrastructure, Waltonchain wants to try and establish new standards and methods. OriginTrail’s token is called TRAC, and it’s an ERC-20 token, making it storable on any ERC-20 compatible wallet. The total supply is capped at 500 million tokens. The value in TRACE tokens comes from their utility on the OriginTrail network. Tokens are spent to store, retrieve, and send data about supply chains. Since TRACE can be bought and sold in a speculative market, that creates the potential for the price to go up, which would be counter to the needs of people on the network looking for stable prices for setting and getting data. However, prices for data saving and retrieval will be determined by auction, which should counter increasing token value for those using OriginTrail as a service. The Internet of Things is a topic that gets a lot of press, and the general consensus is that it will be standard practice in the future for almost everything in the world to be tracked and traced for a wide variety of purposes. OriginTrail is one company that is demonstrating a concrete plan for exactly how that will be manifest. There really isn’t much to criticize in terms of the overall intention of the project. OriginTrail has identified a weak point in the very important world of supply chain management, that of reliable transfer of information all the way up and down the chain, and aims to provide a workable and clearly understood solution.
