Dogecoin mascot is a “dog“. The Shiba Inu is a Japanese breed of dog that was popularized as an online meme and represents Dogecoin.
It is also said to be a Bitcoin clone that has reached success through clever marketing.
Dogecoin uses a simplified variant of the scrypt key derivation function as its proof of work with a target time of one minute per block and difficulty readjustment after every block. The block rewards are fixed and halve every 100,000 blocks. Starting with the 600,000th block, a permanent reward of 10,000 Dogecoin per block will be paid.
