As discussed, Dogecoin has its own blockchain, inspired by the Bitcoin fork – Litecoin. Dogecoin and Litecoin can be mined using the same machine with no extra costs thanks to merged mining. It is because of this merged mining technique that DOGE was profitable to mine and thus survived.
Dogecoin can process 30 transactions per second, with transactions costing a few cents. Typically, Dogecoin transactions are confirmed in a few minutes.
On the other hand, Shiba Inu does not have its own blockchain. Instead, it is built on top of the Ethereum blockchain. As a result, Shiba Inu can process only up to 15 transactions per second. Furthermore, due to the increasing congestion and the resulting high gas fees on Ethereum, Shiba Inu transactions cost a few dollars in gas fees and are confirmed within a few minutes.
In addition to SHIB, the Shiba Inu ecosystem has two other ERC-20 tokens – LEASH and BONE. These tokens allow you to trade on the ShibaSwap exchange. According to their website, ShibaSwap has over $500 million in total value locked (TVL). Furthermore, Dapp.com shows that ShibaSwap processes over 3000 trades every day.
