Zen is a decentralized financial platform, built from scratch with the goal of providing people with a secure, scalable and useful infrastructure for creating their own financial instruments, and trading them directly without intermediaries.The Zen blockchain is secured by multiple proof-of-work algorithms, with token-holder voting on the balance between them. Multi-hash mining creates robust incentives for miners to deliver efficient, reliable security.Zen smart contracts are written and secured by a subset of the F* functional programming language, allowing users to: A) Prove the amount of resources a contract will consume and provide the necessary fees for running the contract to miners, removing the need for a “gas” based system.B) Prove their contracts meet a given specification, meaning they can prove the contract will definitely do (or not do) something given a specific set of parameters.The Zen platform comes with a built-in solution for oracles, which provide contracts with useful real world data.Finally, Zen is integrated with the Bitcoin blockchain, allowing contracts to observe and respond to native bitcoin transactions
Dogecoin is a cryptocurrency based on the popular 'Doge' Internet meme and features a Shiba Inu on its logo. Dogecoin is a Litecoin fork. Introduced as a 'joke currency' on 6 December 2013, Dogecoin quickly developed its own online community and reached a capitalization of US$60 million in January 2014. Compared with other cryptocurrencies, Dogecoin had a fast initial coin production schedule: 100 billion coins were in circulation by mid-2015, with an additional 5.256 billion coins every year thereafter. As of 30 June 2015, the 100 billionth Dogecoin had been mined. Dogecoin was created by Billy Markus from Portland, Oregon and Jackson Palmer from Sydney, Australia. Both wanted to create a fun cryptocurrency that will appeal beyond the core Bitcoin audience. Dogecoin is primarily used as a tipping system on Reddit and Twitter where users tip each other for creating or sharing good content. The community is very active in organising fundraising activities for deserving causes. The developers of Dogecoin haven’t made any major changes to the coin since 2015. This means that Dogecoin could get left behind and is why Shibas are leaving Dogecoin to join more advanced platforms like Ethereum. One of Dogecoin strengths is its relaxed and fun-loving community. However, this is also a weakness because other currencies are way more professional. To purchase Dogecoin, it involves downloading a crypto wallet, setting up a crypto exchange account and then trading away for your desired crypto currency. Once we have set up an account with a DOGE currency exchange and deposited some funds, you are ready to start trading.
