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.

Wallets’ owners create new transaction using secure channel either online or offline Both wallets participate in signing the transaction using Schnorr protocol Wallet sends transaction to node Each transaction contains a list of Inputs and Outputs represented by Pedersen Commitments, as well as explicit fees and kernels. Each transaction also contains non-interactive zero knowledge range proof to verify that the output transaction value is positive Transaction is verified by the node Each transaction is verified with respect to the recent blockchain state which is stored as a Merkle Tree. The root hash of the tree is recorded in block header along with a proof of work. In addition, each node periodically creates compacted history to allow ‘fast sync’ of new and existing nodes. Transaction is added to the mining pool A block is mined every minute and is sent back to the node for verification and distribution. Mined blocks containing the new transactions are sent to the known peers A valid block that is extending the longest chain is accepted as a new Tip and propagated further until full consensus is reached. Fast sync When a new node connects to the network for the first time it can request compacted history containing only system state and blockchain headers. There is no need to retrieve the entire transaction history.
