TrueUSD provides its token holders regular attestations of escrowed balances, full collateral, and also the legal protection against misappropriating underlying USD. The team believes that TrueUSD will be able to come up with the stable trading instrument for the traders of cryptocurrency that has been long-awaited. This will allow the businesses and consumers to use the digital currency as a medium of an exchange. The goal of the TrueUSD team was to build a coin that is stable and which can be used and trusted by them too. TrustToken is a platform that creates the tokens backed by assets that can easily be purchased and sold all around the world. The first asset token of TrustToken is TrueUSD, which is a stable coin and can be redeemed 1-for-1 for US dollars. TrustToken have partnered with registered fiduciaries and banks for holding the funds securely backed by TrueUSD tokens. To increase the amount of security, fiduciaries, and banks directly handle all the funds. Escrowed funds do not give access to the TrueUSD system. TrueUSD works with various trust companies which already manage around billions of dollars. Just pass an AML/KYC check, send USD to a trust company with an agreement of escrow. When the funds get verified, their API tells the smart contract of TUSD to mint an equal amount of TUSD to your public Ethereum address. The USD funds are regularly verified in scheduled attestations by a very much trusted auditing firm. USD funds are kept safely in a third party account, that is escrow accounts, wherein TrustToken does not hold any direct access to the funds and cannot abscond with them even if they wish to. The token burning and minting system makes sure that every TUSD token is backed by 1 USD. A mandatory check of AML/KYC makes sure that TUSD keeps shady people away from the entire project. TUSD makes faster transactions in low transaction fees. Even though TUSD is a unique offering, it is most likely overshadowed by its bigger competitors - Tether. While TUSD arguably offers more security and features, it may be losing the marketing battle. This is not to say that the situation will remain the same. With more crypto investors joining the market every day, the good times for TUSD may be on their way.
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.
