ドージコイン (DOGE) トケノミクス

Dogecoin (DOGE) operates as a peer-to-peer payment settlement layer using a Proof-of-Work (PoW) consensus mechanism, derived from a fork of Litecoin, which itself is a fork of Bitcoin. Its token economics are characterized by an inflationary supply model designed to incentivize miners and maintain network security.

Issuance Mechanism

Dogecoin utilizes an inflationary issuance mechanism with an uncapped maximum token supply.

• Block Reward: The network issues a permanently fixed block reward of 10,000 DOGE per block.
• Block Time: A new block is generated approximately every one minute.
• Annual Issuance: This fixed block reward results in a predictable annual issuance of 5 billion new DOGE tokens.
• Inflation Rate: While the total supply is uncapped, the fixed annual issuance means the rate of inflation decreases over time relative to the total circulating supply. This inflation rate averages roughly 3-4% per year, similar to other major PoW assets like Bitcoin (BTC) and Ethereum (ETH).
• Security Rationale: The continuous issuance is considered necessary to pay miners and secure the network indefinitely. The Dogecoin Foundation argues that capping the supply, as Bitcoin does, would eventually render the network insecure once block rewards diminish completely, necessitating a change in the consensus mechanism.

Allocation Mechanism

The entire DOGE supply is distributed exclusively through Proof-of-Work (PoW) mining rewards.

• No Pre-Allocation: Unlike many newer crypto projects, Dogecoin did not have an Initial Coin Offering (ICO), airdrop, or pre-mine.
• Team/Founder Allocation: No tokens were allocated to the project team, employees, directors, or advisors.
• Circulating Supply: As of May 20, 2024, the circulating token supply was approximately 144.38 billion DOGE.
• Holder Concentration: A notable characteristic of Dogecoin's distribution is the high concentration of tokens among a small number of addresses. As of May 20, 2024, the top 10 wallet addresses collectively held approximately 65.47 billion DOGE, representing about 45.35% of the circulating supply. Four specific wallet addresses individually held over 3.00% of the circulating supply.

Usage and Incentive Mechanism

The primary function of DOGE is as a utility token for payments and network security.

Token Utility

• Peer-to-Peer Payments and Value Storage: DOGE functions as a medium of exchange, enabling users to send and receive funds without intermediaries.
• Settling Network Transaction Fees: DOGE is used to pay transaction fees, which incentivize miners to process and confirm transactions. Transaction fees are calculated based on the transaction's size in bytes, and users can adjust fees to influence confirmation priority. There are plans to further lower fees by 100x.

Incentive Mechanism (Mining)

• Proof-of-Work (PoW): Miners secure the network using the Scrypt hashing algorithm. The miner who successfully generates a valid block receives two forms of compensation:
  1. Block Reward: The fixed 10,000 DOGE newly minted tokens.
  2. Transaction Fees: All transaction fees associated with the confirmed transactions in that block.
• Auxiliary Proof-of-Work (AuxPoW): Dogecoin employs AuxPoW, which allows miners to submit proofs from the Litecoin blockchain to be accepted as valid on the Dogecoin blockchain. This enables merged mining, where miners can mine both DOGE and Litecoin simultaneously, increasing the security of the Dogecoin network by leveraging Litecoin's hash rate.

Future Development and Utility

The Dogecoin Foundation is actively working on expanding the token's utility and infrastructure:

• GigaWallet Project: A scalable backend solution aimed at enabling faster and easier integration of Dogecoin payments for retailers, game developers, and social platforms.
• DRC-20 Standard: The introduction of the DRC-20 token standard allows for the issuance of fungible tokens and NFTs within the Dogecoin network, expanding its functionality beyond a simple payment mechanism.
• Proof-of-Stake (PoS) Exploration: The Dogecoin Foundation is exploring implementing a "Community Staking" version of PoS, potentially in collaboration with Vitalik Buterin, to allow smaller holders to participate in network security and distribute a portion of the yearly issuance to charities. However, this is still in the exploratory phase, and currently, no staking or liquidity provisioning mechanisms exist for DOGE.

Locking Mechanism and Unlocking Time

Dogecoin does not feature a traditional token locking or vesting mechanism for its circulating supply, as the entire supply is distributed via mining rewards.

• No Vesting/Cliffs: Since DOGE is distributed solely through mining rewards and there were no token sales (ICO, seed, strategic rounds) with associated vesting schedules, there are no pre-defined token locking mechanisms or unlocking times for the core token supply.
• Daily Issuance: The inflationary issuance acts as a continuous, linear release of new tokens into the circulating supply. Dogecoin releases a steady stream of new supply daily, equivalent to 10,000 DOGE per minute, or 14.4 million DOGE per day.
• Missing Unlock Data: Specific token unlock events or schedules, which typically apply to pre-allocated tokens for teams or investors, are not applicable to Dogecoin's native token distribution model. Information regarding token unlock events for Dogecoin was not available.
