Grin coin is a private & lightweight open source project based on the mimblewimble blockchain implementation. MimbleWimble is a lightweight blockchain protocol proposed by anonymous author that goes by the name Tom Elvis Jedusor (inspired by Harry Potter) in July 2016. Since then, the proposal has gained a huge following among Bitcoin and privacy advocates. Unlike bitcoin or ethereum, there are no addresses in Grin. In order to transact using Grin, both wallets must communicate with each other online with the results broadcasted to the network. Another key different is that transaction history (sender, receiver, amount) will not be recorded on the blockchain. Due to the removal of these information from the transaction, the data size remains small and that keeps the blockchain lightweight. New nodes can easily join the network without having to download a large blockchain. Grin coin was launched without an ICO, fundraising, or pre-mine. Developers around the world contribute openly with the goal to ensure the coin distribution remains as fair as possible. There are 2 popular wallets widely available to interact with the Grin network.

There are 2 hashing algorithms involved with Grin. Cuckoo-29 is meant for GPU mining while Cuckoo-31 is meant fo ASIC mining. This is a deliberate design to encourage miners to eventually move into ASIC mining for efficiency while keeping it fair at the beginning of the launch. Grin coin has launched its mainnet on 15th January 2019 and is now available for mining and trading.
Content: We hope to, basing on the technology of block chain, adopting unique non-tamper distributed ledger characteristics of the block chain, build the traceability cloud platform, solve the enterprise's difficulties in information traceability, anti-counterfeit, verification and mobile marketing during commodity production, circulation and distribution and terminal consumption process through the sub-chain of the landing project and corresponding DAPP application, and provide a fast and efficient cluster of cloud services development for the technical developers, so as to solve the problem of 'trusted' for brand enterprises and consumers, and then build a new block chain ecosystem ---Traceability Chain as the future world-selectable internet value transmission protocol, and push forward the practicability and usability of the whole block chain industry. As the most promising block chain ecosystem, it perfectly combines the advantages of Ethereum and Bitshares. Traceability Chain will also constantly and gradually form the block chain economy through the construction of the foundation platform, the design and development of the software and hardware products, the development of various products and the development and iteration of the commercial landing project, improve the industry efficiency, and promote the effective and collaborative development of the society.
