Storj is an open-source platform that leverages the blockchain to provide end-to-end encrypted cloud storage services. Instead of maintaining its own data centres, Storj platform relies on a peer-to-peer network of individuals or entities sharing their storage spaces. The Storj project is owned and developed by Storj Labs Inc. Storj intends to facilitate a faster, cheaper, and secure file storage solution than traditional cloud storage platforms. To achieve its goal, Storj deploys several innovative technologies and methods to make sure that users are able to store and retrieve data in a fastest possible way while not compromising the security and integrity of data. Storj Labs Inc was founded in 2014 by Shawn Wilkinson with co-founders John Quinn. The company is headquartered at Atlanta, Georgia in the United States. Shawn was previously appointed as CEO, but in March 2018, he stepped down from the post to serve as CSO of the company. Shawn was replaced by Ben Golub (Ex-CEO of Docker) who currently serves as the Executive Chairman & Interim CEO. Co-founder John Quinn has been appointed as the Chief Revenue Officer. The company launched its initial coin offering (ICO) of the new tokens on May 19, 2017. At the end of the token sale on May 25, 2017, the company had raised about $30 million. Storj Labs allowed SJCX holders to exchange their tokens with the new ones in a 1:1 ratio through a token conversion campaign which lasted till October 2017. Storj Labs pre-mined its entire supply of tokens at the inception; no new tokens can be created via STORJ mining. Nevertheless, users can obtain STORJ tokens by becoming a farmer in the network. Another obvious way to acquire STORJ is through trading on a cryptocurrency exchange. Up until now, cloud storage companies have dictated the terms of service to their users, and as a result, there has been little to no competition within this digital sector. However, with the introduction of Storj, all of that may change.' Check out CoinBureau for the full review on OmiseGo.
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.
