POWPOWER has been focusing on the mining area for 4 years, is the official distributor of IPollo, and has established long-term partnerships with Bitmain, Avalon, Jas miner, inno, Whatsminer and Goldshell.

Grin, the Chinese name is “grinning tooth” (you can understand it as an expression in the expression pack), also transliterated as “green”. From today’s perspective, Grin’s explosion is full of drama. Different from the old traditional cryptocurrencies such as BTC and ETH, which have been gradually accumulated and carried forward by the community, Grin has become popular entirely by virtue of short-term traffic exposure and intensive screen brushing.

Grin currently introduces two Pow algorithms. The main algorithm is Cuckatoo31+ (31 algorithm for short) which is designed to be ASIC friendly. The secondary algorithm is Cuckaroo29 (referred to as the 29 algorithm), which is ASIC-resistant. The Grin team hopes that by controlling the proportion of blocks produced by the two algorithms, miners using different equipment can get little difference in income. In this way, Grin will not be monopolized by “miners” in the early stage of computing power, and from a long-term perspective, it also provides a controllable entry channel for the inevitable scene of ASIC mining machines.

Grin is a minimal implementation of the MimbleWimble protocol. MimbleWimble is a blockchain format and protocol that provides very good scalability, privacy, and fungibility, relying on robust cryptographic primitives. It addresses the gap (between real world needs) of almost all currently implemented blockchains. The white paper of MimbleWimble can be found in the WiKi of this project, which is open.

Grin is an open-source software project that implements the MimbleWimble blockchain and fills in some of the things (missing in the MimbleWimble protocol) necessary to implement a full blockchain and cryptocurrency.

The main purpose and features of the Grin project are as follows:

The default feature of privacy protection. This makes it fully fungible and retains the ability to selectively disclose information on demand.

The block size is adapted to the transaction volume, and historical transactions only retain about 100 bytes of transaction kernel, which saves a lot of space compared to other blockchains.

Strong and proven cryptography. MimbleWimble uses only elliptic curve cryptography, which has been tried and tested for decades.

Simple design makes future code review and maintenance easy.
