ドージコイン (DOGE) トケノミクス

Dogecoin (DOGE) is a decentralized, peer-to-peer digital currency that originated as a joke in 2013 but has since evolved into a significant payment settlement layer and speculative asset. Its token economics are characterized by a unique inflationary model, a distribution history rooted entirely in mining, and a lack of traditional corporate-style locking or vesting mechanisms.

Issuance Mechanism

Dogecoin operates on a Proof-of-Work (PoW) consensus mechanism using the Scrypt hashing algorithm. Unlike Bitcoin, which has a hard cap of 21 million tokens, Dogecoin has an uncapped maximum supply.

• Block Rewards: Miners receive a permanently fixed reward of 10,000 DOGE per block.
• Block Time: The network targets a block production rate of approximately one block every 60 seconds.
• Annual Issuance: This fixed reward structure results in a predictable annual issuance of approximately 5 billion DOGE.
• Inflation Rate: Because the yearly issuance is fixed while the total supply grows, the relative inflation rate decreases over time. As of mid-2022, the inflation rate was estimated at roughly 3-4% per year, which is comparable to the inflation rates of other major assets like Bitcoin and Ethereum.
• Auxiliary Proof-of-Work (AuxPoW): Since 2015, Dogecoin has employed AuxPoW, allowing it to be "merge mined" with Litecoin. This enables miners to secure both networks simultaneously using the same computational effort, which significantly enhanced Dogecoin's network security and hashrate.

Allocation Mechanism

Dogecoin's allocation is distinct from many modern cryptocurrency projects because it did not conduct an Initial Coin Offering (ICO), pre-mine, or private sale.

• Mining-Based Distribution: The entire supply of DOGE is distributed through PoW mining rewards. There was no initial allocation to the founders, employees, or early investors.
• Founder Involvement: The original creators, Billy Markus and Jackson Palmer, are no longer involved in the project's development or governance.
• Holder Concentration: Despite its fair launch, Dogecoin exhibits significant holder concentration. As of May 2024, the top 10 wallet addresses held approximately 65.47 billion DOGE, representing roughly 45.35% of the circulating supply. One single address held over 22% of the total supply.

Usage and Incentive Mechanism

The primary utility of DOGE is as a medium of exchange and a tool for network security.

• Peer-to-Peer Payments: DOGE is used for microtransactions, online tipping, and payments. It has gained real-world adoption with companies such as Tesla, SpaceX, and AMC accepting it as a payment option.
• Transaction Fees: Users pay fees in DOGE to have their transactions processed. These fees are paid to miners in addition to the block reward. Fees are relatively low, historically averaging around $0.02 per transaction.
• Miner Incentives: The combination of the 10,000 DOGE block reward and transaction fees provides the economic incentive for miners to provide the computational power necessary to secure the blockchain.
• DRC-20 Standard: A newer development in the ecosystem is the DRC-20 token standard, which enables the issuance of fungible tokens and NFTs directly on the Dogecoin network.

Locking Mechanism and Unlocking Time

Because Dogecoin was launched as a fair-distribution PoW project without a pre-mine or venture capital funding, it does not have the traditional locking mechanisms or vesting schedules found in many other protocols.

While there are no protocol-level locks, the Dogecoin Foundation has explored the concept of "Community Staking" under a Proof-of-Stake (PoS) model. This proposal aims to allow more users to participate in network rewards, with a portion of the issuance potentially directed toward charitable causes. However, as of May 2024, this remains a proposal under investigation and has not been implemented.
