GRIN is called Smile Coin in Chinese. It is a completely community-based open source project based on the MimbleWimble protocol. GRIN fills in the important missing parts of the MimbleWimble protocol and has strong privacy protection features, block scalability and data reviewability. . At the same time, GRIN has no fair issuance, no ICO, and no early or founder rewards. GRIN is completely driven by the community. According to the plan, Grin plans to start fair mining around January 15, 2019, and according to its ASIC-resistant design, anyone can participate in Grin mining through a laptop in the short term.

Technical features of GRIN coin:

Grin is developed using the Rust programming language. Like Bitcoin, Grin also uses a proof-of-work (PoW) mechanism. The slight difference is that Grin uses a mechanism called Cuckoo.
Cycle's PoW algorithm is currently highly resistant to ASICs. In addition, Grin also made some minor changes to MimbleWimble to make its design "quantum resistant".

Developed by anonymous engineers

Many of Grin's development teams are anonymous and scattered around the world. When Satoshi Nakamoto used blockchain technology to mine Bitcoin, he did not disclose his identity, but adopted an anonymous method. He seemed to have anticipated the subsequent results when he created the genesis block.

When Grin emerged in 2016, it was also launched by anonymous engineers. To be precise, Grin is an implementation of MimbleWimble, a large-scale, scalable blockchain-based ledger. Grin is based on the MimbleWimble cryptocurrency. MimbleWimble by the pseudonym Tom
Elvis was launched by an anonymous engineer, while Grin's algorithm was developed by an anonymous engineer who went by the pseudonym Ignotus Peverell.

Strong privacy and scalability

Grin is private and scalable. It can be said that Grin is a new cryptocurrency dedicated to providing "privacy" and "scalability". Unlike cryptocurrencies such as Bitcoin, Grin uses MimbleWimble's privacy-preserving blockchain format, making tokens interchangeable and users will have strong anonymity guarantees.

Grin on MimbleWimble supports confidential transactions, conceals all transaction data through homomorphic encryption, and uses range proof to solve validity problems, but it does not support scripting. In the Bitcoin network, new verification nodes joining the network must synchronize from the genesis block and verify the validity of each transaction. In the Grin network, new validating nodes only need to synchronize block headers, unspent transaction outputs, and redundant data (transaction data that records the difference between outputs and inputs, as well as the signatures created by the parties involved in the transaction). Transaction information is indistinguishable, there is no address or amount. In other words, you cannot query the specific address and quantity of each transaction because the information is disrupted.

Mimblewimble stores only a small amount of data in the blockchain, making it cheap and easy to run a full node, and new nodes will be able to synchronize with the network quickly and efficiently. Additionally, MimbleWimble can be implemented both on Bitcoin’s sidechain and as an extension block. Grin coin mining tutorial:

Summary: From the design of its monetary policy, we can see that Grin is not suitable for short-term participation in speculation. This is very different from Zcash’s slow start, which once hit 3,000 BTC.
The sky-high Zcash hype event was also due to the extremely scarce initial supply of tokens, which provided good conditions for speculation. At the same time, Grin has no upper limit, which will also cause a lot of controversy, which is very different from the design of Bitcoin.
