Litecoin is a peer-to-peer cryptocurrency created by Charlie Lee. It was created based on the Bitcoin protocol but differs in terms of the hashing algorithm used. Litecoin uses the memory intensive Scrypt proof of work mining algorithm. Scrypt allows consumer-grade hardware such as GPU to mine those coins. Why Litecoin? Litecoin is a cryptocurrency that has evolved from Bitcoin after its own popularity in the industry, this alternative, or ‘altcoin’ has emerged to allow investors to diversify their digital currency package, according to Investopedia. Litecoin is one of the most prominent altcoins and was created by former Google employee and Director of Engineering at Coinbase, Charlie Lee. Litecoin was the first to alter Bitcoin and the most significant difference is that it takes 2.5 minutes for Litecoin to generate a block, or transaction, in comparison to Bitcoin's 10 minutes. ‘While this matters little to traders, miners who use hardware to run Bitcoin's network cannot switch over to Litecoin. This keeps bigger mining conglomerates away from Litecoin because they cannot easily optimize their profits by swapping to another coin, contributing to a more decentralized experience. Litecoin also has bigger blocks, and more coins in circulation, making it more affordable and swift when transacting,’ Investopedia explained. As explained above, Litecoin can transact a lot faster than Bitcoin, but there are also a number of other characteristics that investors need to know before trading. Litecoin can handle higher volumes of transactions because of the capability of transacting faster and if Bitcoin attempted to transact on the scale of its altcoin, a code update would be needed. However, Litecoin’s blocks would be larger, but with more ‘orphaned blocks'. The faster block time of litecoin reduces the risk of double spending attacks - this is theoretical in the case of both networks having the same hashing power. Litecoin Technical Details: The transaction confirmation time taken for Litecoin is about 2.5 minutes on average (as compared to Bitcoin's 10 minutes). The Litecoin network is scheduled to cap at 84 million currency units. Litecoin has inspired many other popular alternative currencies (eg. Dogecoin) because of its Scrypt hashing algorithm in order to prevent ASIC miners from mining those coins. However it is said that by the end of this year, Scrypt ASIC will enter the mass market.
Qtum is a decentralized and open-source smart contracts platform and value transfer protocol. Qtum uses proof-of-stake consensus, meaning node operators are rewarded for validating transactions. It is a DGP governed blockchain where community participants can vote to change certain network parameters. Qtum is built on a bitcoin core fork, but the foundation has created its own hybrid blockchain with the help of several key tools. The coin uses bitcoin’s chain because of its simple and stable nature, allowing the foundation to build upon it more easily. As the QTUM project is a hybrid of Bitcoin and Ethereum, its team comprises of members from both Bitcoin and Ethereum community. They also have team members who formerly worked with Tencent, Alibaba, Nasdaq etc. Apart from that, they are backed by some notable VCs and prominent people from the Blockchain community such as Patrick Dai (Project Co-Founder), Neil Mahi (Chief Blockchain Architect/Co-Founder) and Jordan Earls (Lead Developer/Co-Founder). Qtum provides a Turing-complete blockchain stack and is able to execute smart contracts and decentralised applications like the Ethereum blockchain. Qtum builds on Bitcoin's UTXO transaction model and uses the Proof-of-Stake algorithm. It is backed by some highly prominent members of the blockchain community such as Anthony Di Iorio, Xu Star, Bo Shen, David Lee, Jehan Chu and Roger Ver. Qtum sold over 10 million dollars’ worth of its tokens after only 90 minutes, eventually raising a total value of $15.7 million before stopping the campaign early after only 5 days. They raised a total amount of 11,156.766 bitcoins (BTC) and 77,081.031 ether (ETH) in exchange for the 51 million Qtum tokens being distributed to the public. In Qtum’s whitepaper, 51% of the coins were distributed to the public via the crowdfunding campaign. Of the remaining 49%, 29% of the coins would be allocated as community incentives, and the remaining 20% would be distributed to the early backers and development team.
