ETHF is a "DRC-20 inscribed concept coin" deployed on the Dogecoin mainnet. DRC20 is a standardized protocol for fungible tokens based on the Cardinals protocol. Currently, besides BTC and LTC, only Dogecoin can implement this function with the UTXO model. The protocol was officially released by Dogewow, a member of the Dogecoin community, on May 9th. In Dogecoin, the smallest indivisible unit is defined as an "elon," where 1 Dogecoin = 100,000,000 elons. As a new experiment on the Cardinals protocol, DRC20 aims to explore the potential for asset tokenization on the Dogecoin blockchain. Currently, wallets and protocols, as rule-makers and drivers of consensus, play crucial roles together.
