ドージコイン (DOGE) トケノミクス

Dogecoin (DOGE) is a peer-to-peer payment settlement layer and meme-based community project that launched in December 2013. Originally created as a fork of Luckycoin (which was a fork of Litecoin), it operates as a decentralized, open-source, and permissionless network. Its token economics are designed to support its primary use case as a medium of exchange rather than a store of value.

Issuance Mechanism

Dogecoin utilizes a Proof-of-Work (PoW) consensus mechanism with a unique inflationary model. Unlike Bitcoin, which has a hard cap of 21 million tokens, Dogecoin has an uncapped maximum token supply.

• Block Reward: The network issues a permanently fixed block reward of 10,000 DOGE per block.
• Block Time: Blocks are produced approximately every 60 seconds (1 minute).
• Annual Issuance: This fixed reward results in an annual issuance of approximately 5.256 billion DOGE.
• Inflation Rate: Because the yearly issuance is fixed at 5 billion coins 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 BTC, ETH, and ADA.
• Mining Algorithm: Dogecoin uses the Scrypt hashing algorithm. It also employs Auxiliary Proof-of-Work (AuxPoW), which allows for "merged mining" with Litecoin. This means miners can secure both networks simultaneously without additional computational effort.

Allocation Mechanism

Dogecoin did not have a traditional Initial Coin Offering (ICO), pre-mine, or venture capital funding rounds. Consequently, there was no formal allocation to a founding team, advisors, or early investors.

• Initial Distribution: The entire supply of DOGE is distributed exclusively as rewards to PoW miners.
• Founder Involvement: The original creators, Billy Markus and Jackson Palmer, are no longer involved in the project and do not hold a designated share of the supply.
• Supply Concentration: Despite the fair launch mechanism, the supply remains highly concentrated. As of May 2024, the circulating supply was approximately 144.38 billion DOGE. Data indicates that the top 1% of addresses control approximately 95% of the active supply, with the top 100 addresses controlling over 65%. One single wallet address has been observed holding approximately 22.09% of the total circulating supply.

Usage and Incentive Mechanism

The DOGE token serves three primary functions within its ecosystem:

1. Peer-to-Peer Payments: DOGE is used as a medium of exchange for tipping, microtransactions, and online payments. It has gained adoption as a payment option by companies such as Tesla, SpaceX, and AMC.
2. Transaction Fees: Users pay fees in DOGE to have their transactions processed by the network. These fees are relatively low, averaging around 2 cents per transaction, though there are development plans to lower them further.
3. Miner Incentives: Miners are incentivized to secure the network through the combination of the fixed 10,000 DOGE block reward and the transaction fees collected within each block.

Locking Mechanism and Unlocking Time

Because Dogecoin is a pure Proof-of-Work chain with no ICO or pre-allocated team tokens, it does not have the standard locking or vesting schedules found in many modern DeFi or Proof-of-Stake (PoS) projects.

• Token Unlocks: There are no recorded token unlock events or "cliffs" for Dogecoin because no tokens were ever locked in smart contracts for investors or team members at inception.
• Staking: As of May 2024, there is no native staking or liquidity provisioning mechanism for DOGE. However, the Dogecoin Foundation has explored a proposal for "Community Staking" via a PoS model that would allow users to participate in network security and earn rewards, though this remains in the proposal/roadmap stage.
• Locktime Scripting: While the protocol supports basic "locktime" functions (similar to Bitcoin's CHECKLOCKTIMEVERIFY) which allow for time-locked transactions (often used in atomic swaps), these are individual transaction features rather than a macro-economic locking mechanism for the total supply.
