Enjin Coin is a cryptocurrency for virtual goods created by Enjin. Enjin is the “largest gaming community platform online” with over 250,000 gaming communities and 18.7 million registered gamers. The Enjin team is designing the coin completely around gaming with the goal of it being the most usable cryptocurrency for the industry. The project includes the Enjin Coin as well as a suite of software development kits (SDKs) that developers can integrate into their games and communities. Bringing blockchain to gaming helps to reduce the high fees and fraud that’s prevalent in the transfer of virtual goods. Enjin Coin is an ERC20 token built on the Ethereum network. With that, the project not only acts as a cryptocurrency but also has smart contract capabilities. It’s also one of the first projects testing the Raiden Network, Ethereum’s version of the Lightning Network. The Enjin Coin platform provides a laundry list of features through its public API and SDKs. To keep things brief, though, we’ll only be discussing a few of the major ones in this article. The largest value Enjin Coin brings to the gaming community is in its creation and management of virtual goods. Developers on each platform can easily create a currency unique to their community that’s backed by Enjin Coin as the parent currency. This gives the coins all the benefits of the blockchain (speed, cost, security, etc…) while still staying customized to their respective platforms. Enjin, the company behind Enjin Coin, is the largest online gaming community creation platform. Started in 2009, the company receives 60 million views per month and transacts millions of U.S. dollars each month in their community stores. The team is deploying Enjin Coin across the entire Enjin CMS platform – over 250,000 gaming websites. Advisors to the project consist of Anthony Diiorio (Ethereum co-founder) and Pat LaBine (previous producer and technical director at Bioware). Enjin has also formed partnerships with Unity, PC Gamer, and NRG eSports. The team held a successful ICO in late 2017 in which they raised ~$35 million between the private and public rounds. Although it’s still a young project, the team spent the last quarter of 2017 building the Platform API, Mobile Smart Wallet, and a Java SDK alongside creating a Minecraft plugin. They’ve got plenty in store for 2018, but the highlights include various platform plugins, the Efinity release, and numerous other SDKs. Enjin also features a tool known as TopLists, which allow users to rank games, servers, teams and any other item. TopLists will be deployed as a decentralized smart contract with functionalities that will allow for market bidding or democratic voting. List creators are incentivized to promote and market their list because these creators will receive tokens when users perform tasks such as voting on their list. Enjin Coin is an ambitious project that aims to integrate online virtual gaming with decentralized technologies. Enjin Coin project promises a lot, and it is only with the passage of time that we will able to see if it can deliver on those promises.
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.
