Bytom is a blockchain protocol for financial and digital asset applications. Using the Bytom protocol, individuals and enterprises alike can register and exchange not just digital assets (i.e. Bitcoin) but traditional assets as well (i.e. securities, bonds, or even intelligence data). Bytom’s mission is “to bridge the atomic [physical] world and the byte [digital] world, to build a decentralized network where various byte assets and atomic assets could be registered and exchanged.” Bytom is an interactive protocol of multiple byte assets, to give it the proper title. Heterogeneous byte-assets (indigenous digital currency, digital assets) that operate in different forms on the Bytom Blockchain and atomic assets (warrants, securities, dividends, bonds, intelligence information, forecasting information and other information that exist in the physical world) can be registered, exchanged, gambled and engaged in other more complicated and contract-based interoperations via Bytom. While Ethereum’s SEC scrutinization as a possible security took the entire crypto market on a downturn in early 2018, Bytom voluntarily submitted to the SEC’s Howey Test and Bytom cryptocurrency was deemed not a security under its DAO watch. This one has potential to make an impact on the cryptocurrency market with low transaction fees, high tech Bytom blockchain technology and an interactive protocol of multiple byte assets that could mark it apart. A Bytom wallet is also on offer and can store plenty more than Bytom coins.
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.
