ドージコイン (DOGE) トケノミクス

Issuance Mechanism

Dogecoin (DOGE) operates on a Proof-of-Work (PoW) consensus mechanism, utilizing the Scrypt hashing algorithm. The issuance of new DOGE tokens is inflationary and uncapped, meaning there is no maximum token supply, unlike Bitcoin's hard cap of 21 million BTC.

The issuance mechanism is characterized by a fixed block reward:

• Block Reward: Permanently fixed at 10,000 DOGE per block.
• Block Time: A new block is generated approximately every 1 minute.
• Annual Issuance: This fixed reward results in a predictable annual issuance of 5 billion DOGE.
• Inflation Rate: Due to the fixed annual issuance against a growing total supply, the rate of inflation decreases over time. The inflation rate averages roughly 3-4% per year, which is comparable to other major PoW assets like Bitcoin and Ethereum.

Dogecoin also employs Auxiliary Proof-of-Work (AuxPoW), a consensus upgrade implemented in 2015. AuxPoW allows Dogecoin to be "merged mined" with Litecoin. This means miners can submit proofs of work from the Litecoin blockchain to be accepted as valid on the Dogecoin blockchain, effectively mining both coins simultaneously and increasing the security of the Dogecoin network.

Allocation Mechanism

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

• No Pre-mine or Token Sales: Based on available information, the project has never completed any funding rounds, such as ICOs or equity rounds.
• Distribution: All newly minted DOGE, along with transaction fees, are allocated to the miners who successfully generate and append a block of confirmed transactions to the blockchain.

As of May 20, 2024, the circulating token supply was approximately 144.38 billion DOGE. However, the distribution among holders shows a high degree of concentration:

• The top 10 wallet addresses collectively hold approximately 65.47 billion DOGE (about 45.35% of the circulating supply).
• Four individual wallet addresses each hold over 3.00% of the circulating supply, with the largest single address holding approximately 31.89 billion DOGE (about 22.09% of the circulating supply).

Usage and Incentive Mechanism

The native token, DOGE, serves several primary functions within the network:

1. Peer-to-Peer Payments and Value Storage

DOGE's stated use case is as a medium of exchange for peer-to-peer payments and value storage, enabling users to send and receive funds without intermediaries. Despite its origins as a meme coin, it has gained some real-world adoption, with companies like SpaceX, AMC, Tesla, Twitch, and the Dallas Mavericks accepting DOGE as a payment option. However, it is noted that DOGE primarily finds adoption as a speculative asset, heavily focused on retail speculation.

2. Network Security and Miner Incentives

Miners are incentivized to secure the network through the PoW consensus mechanism. Rewards for miners include:

• The fixed 10,000 DOGE inflationary block reward.
• All transaction fees associated with the confirmed transactions in the block.

Transaction fees are paid in DOGE and compensate miners for the computational resources used to validate transactions. Fees are calculated based on the transaction's size in bytes, and users can adjust the fee to influence transaction priority.

3. Ecosystem Development and Future Utility

The Dogecoin Foundation is actively working on expanding DOGE's utility and adoption through its "Trailmap." Key development initiatives include:

• GigaWallet Project: A hosted, enterprise-grade wallet solution aimed at providing scalable, user-friendly APIs for developers and businesses to integrate Dogecoin payments easily.
• DRC-20 Standard: The introduction of the DRC-20 token standard enables the issuance of fungible tokens and NFTs within the Dogecoin network, opening up potential for tokenization and new applications like gaming assets and digital collectibles.
• Community Staking (Proposed): The Dogecoin Foundation is exploring implementing a community staking model through a Proof-of-Stake (PoS) mechanism, potentially in collaboration with Vitalik Buterin. The goal is to create a fairer, more sustainable proof mechanism that rewards smaller holders and allocates a portion of the yearly issuance to charities. This proposal is still in the discussion and prototyping phase.

Locking Mechanism and Unlocking Time

As of May 20, 2024, Dogecoin does not feature any native locking, staking, or liquidity provisioning mechanisms for DOGE tokens within its current Proof-of-Work consensus model.

• No Vesting Schedule: Since the entire supply is distributed via mining rewards, there are no pre-allocated tokens subject to vesting cliffs or unlocking schedules for the team, investors, or foundation, as is common in projects with token sales.
• Inflationary Release: The only "unlocking" or release of new tokens occurs continuously through the fixed block reward of 10,000 DOGE per minute, which is immediately available to the successful miner. This results in a steady, linear daily release of new supply.

While the Dogecoin Foundation is exploring a potential Proof-of-Stake model that would involve community staking, details on any associated locking periods or unlocking times for this future mechanism are not yet available.
