D20 is a "DRC-20 Inscribed Concept Coin" deployed on the Dogecoin mainnet. DRC20 is a homogeneous token standardization protocol based on the Cardinals protocol. Currently, only Dogecoin, besides BTC and LTC, can implement the UTXO model. The protocol was officially released by the Dogecoin community Dogewow on May 9th. In Dogecoin, the smallest indivisible unit is defined as "elon," where 1 Dogecoin = 100,000,000 elons. As a new experiment on the Cardinals protocol, DRC20 aims to explore the potential of asset tokenization on the Dogecoin blockchain. Currently, wallets and protocols play a crucial role as rulemakers and consensus drivers.
