イーサリアム (ETH) トケノミクス

Ethereum's token economics, often referred to as "Ultrasound Money," is designed to balance network security, sustainability, and scarcity. Since its transition to Proof-of-Stake (PoS) and the implementation of key protocol upgrades, the network has moved toward a model where the circulating supply can become deflationary based on network activity.

Issuance Mechanism

Ethereum's issuance is dynamic and tied directly to the security needs of the network. Under the current Proof-of-Stake consensus, new ETH is minted as "base rewards" to incentivize validators for securing the blockchain.

• Dynamic Issuance: The amount of new ETH created is a function of the total amount of ETH staked. As more ETH is staked, the individual reward rate for validators decreases, but the total network issuance may increase to ensure sufficient security.
• Validator Rewards: As of late 2024, the projected annual issuance of rewards is approximately 703,000 ETH. These rewards are split between block proposers and attesting validators.
• Deflationary Offset (Burn Mechanism): Through the EIP-1559 upgrade, a portion of every transaction fee (the "base fee") is permanently removed from circulation (burned). When network demand is high, the amount of ETH burned can exceed the amount issued to validators, leading to a net decrease in total supply. Current estimates suggest an annual burn of approximately 954,000 ETH based on usage statistics.

Allocation Mechanism

Ethereum's initial distribution occurred through a public crowdsale in 2014. Unlike many modern protocols that have complex vesting schedules for various stakeholders, the majority of Ethereum's supply is now circulating and held by the community, validators, and decentralized protocols.

Usage and Incentive Mechanism

ETH serves as the lifeblood of the Ethereum ecosystem, providing both utility for users and incentives for network maintainers.

• Gas Fees: ETH is the native token used to pay for transaction gas fees. These fees are required for any interaction with the network, such as sending tokens or executing smart contracts.
• Staking Incentives: To secure the network, users are incentivized to "stake" their ETH. By locking 32 ETH, a user can run a validator and earn a combination of new issuance (base rewards), priority fees (tips), and maximal extractable value (MEV) rewards.
• Collateral and Utility: Beyond the protocol level, ETH is used as collateral in decentralized finance (DeFi) applications, as a unit of account for NFTs, and can be wrapped (WETH) to interact with ERC-20 compatible protocols.

Locking Mechanism and Unlocking Time

The locking of ETH is primarily associated with the security of the consensus layer and the bridging of assets to other networks.

• Consensus Staking: To participate in validation, users must deposit 32 ETH into the Beacon Deposit Contract. This ETH acts as collateral against dishonest behavior.
• Withdrawal Process: Following the Shapella upgrade in April 2023, validators have the ability to withdraw their earned rewards or fully exit the protocol.
• Unlocking Time: Validators can perform "partial withdrawals" (withdrawing rewards above the 32 ETH requirement) or "full withdrawals" (exiting the validator entirely). The time to unlock and receive these funds depends on the "exit queue," which limits how many validators can leave the network at once to maintain stability.
• Bridging Locks: When ETH is moved to Layer 2 solutions or other chains, it often utilizes a "lock and mint" mechanism. The native ETH is locked in a smart contract on the Ethereum mainnet, and an equivalent token is minted on the destination chain. Unlocking occurs when the user "burns" the representative token on the destination chain to release the original ETH on the mainnet.
