Dogecoin

Originally created in 2013 by software engineers Billy Markus and Jackson Palmer as a market parody, the project held no public sale or venture capital rounds. The network operates as a fork of LuckyCoin, which itself was a fork of Litecoin, using a proof of work consensus mechanism. It employs the Scrypt algorithm to ensure the mining process remains fast and efficient, with new blocks processed every 60 seconds.

A unique technical feature is its use of merged mining, allowing miners to secure Dogecoin simultaneously with other Scrypt-based networks like Litecoin. To keep transaction fees low and the network running indefinitely, Dogecoin features an uncapped supply where new coins are added forever.
