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.
Polymath simplifies the legal process of creating and selling security tokens. It makes a new token standard, the ST20, and enforces government compliance. Only a “list of authorized investors and their Ethereum wallet addresses” can hold ST20 tokens. Therefore, token issuers don’t need to worry about the legal implications of your security falling into the wrong hands. In order to launch a legally compliant token, the Polymath platform brings together issuers, legal delegates, smart contract developers, KYC verification, and a decentralized exchange. All transactions on the Polymath platform take place using the native POLY token. Polymath has programmable equity. Polymath enables companies to take control of their equity issuance through programmable code. It is raising in cryptocurrency opens up an entire wealth of new investors. Polymath eliminates the middleman and financial structures that hinder the deployment of equity. There is a trove of wealth that is untouched by Wall Street that can now be accessed through Polymath. In 2017, Polymath raised over $1.2 billion in funding by selling utility tokens and security tokens. Utility tokens, such as Waltonchain, give you access to a token’s network and are far more common than security tokens. Security tokens, however, provide equity or a claim to dividends from a company. As a result, security tokens, like any securities, are subject to government regulation. Polymath’s new standard for blockchain security tokens aims to embed the necessary regulatory requirements into smart contracts and comply entirely with government security regulations. A wide array of security tokens that will be listed on Polymath at some point will require investors to be accredited, or to be from specific countries.
