About grain.io
GRAIN is a platform that allows labor contracts to be processed via smart contracts on the Ethereum blockchain. It is stated that this will reduce costs while increasing flexibility among workers as well as employers.
Product
GRAIN aims to create a platform that transforms labor contracts by implementing them as smart contracts. Once contract termination consensus is reached, GRAIN tokens are awarded to recipients as specified by the contract, and can then be exchanged for fiat currency. The potential target user base is vast, and the level of competition for blockchain-related projects dedicated specifically to this purpose is relatively low.
Use of Blockchain
GRAIN is an ERC20 compliant token used as fuel for transactions that take place in the GRAIN ecosystem. The section in the whitepaper dedicated to discussing the GRAIN token consists primarily of a reiteration of general features of blockchain technology and smart contracts — features which are not unique to GRAIN. As such, the need for GRAIN to create a custom token is questionable and seems to be primarily a means for funding the platform.
Whitepaper
The whitepaper is quite concise at 25 pages with large margins and many figures. Business related details are discussed in satisfactory detail, with token and funding allocation properly addressed, as well as a page of discussion regarding the business case of the platform and other details such as transaction fees. The document is lacking, however, in technological details of how the platform will operate. Overall the whitepaper is concise, well organized, and visually pleasing.
Roadmap
The roadmap presented in the whitepaper spans from Q2 2016 to Q1 2019 and contains low levels of detail with regard to the business-focused milestones. Milestones reached thus far have been mainly about raising capital and establishing the organization. The first public beta test of GRAIN is planned to occur during Q2 of 2018.
