Beam Mimblewimble is a scalable, fungible, and confidential cryptocurrency based on the Mimblewimble implementation. WHY BEAM? Core features include complete control over your privacy, All transactions are private by default, No addresses or other private information are stored on the blockchain, Superior scalability due to compact blockchain size, Opt-in Auditability, Support online and offline transactions, atomic swap, hardware wallets integration. Governance model No premine, No ICO. Backed by Treasury Establishing a non-profit foundation to govern the protocol after Mainnet launch How does it work? Wallets’ owners create new transaction using secure channel either online or offline Both wallets participate in signing the transaction using Schnorr protocol Wallet sends transaction to node Each transaction contains a list of Inputs and Outputs represented by Pedersen Commitments, as well as explicit fees and kernels. Each transaction also contains non-interactive zero knowledge range proof to verify that the output transaction value is positive Transaction is verified by the node Each transaction is verified with respect to the recent blockchain state which is stored as a Merkle Tree. The root hash of the tree is recorded in block header along with a proof of work. In addition, each node periodically creates compacted history to allow ‘fast sync’ of new and existing nodes. Transaction is added to the mining pool A block is mined every minute and is sent back to the node for verification and distribution. Mined blocks containing the new transactions are sent to the known peers A valid block that is extending the longest chain is accepted as a new Tip and propagated further until full consensus is reached. Fast sync When a new node connects to the network for the first time it can request compacted history containing only system state and blockchain headers. There is no need to retrieve the entire transaction history.
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.
