이더리움 (ETH) 토크노믹스

The token economics of Ethereum (ETH) are designed to secure the network, incentivize participation, and manage the supply of its native asset, Ether (ETH). Following the transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS) with "The Merge," Ethereum's monetary policy shifted significantly, introducing a deflationary mechanism often referred to as "Ultrasound Money."

Issuance Mechanism

Ethereum's issuance mechanism is characterized by a dynamic supply model that balances new token creation (issuance) with token destruction (burning), aiming for a net deflationary effect.

• Issuance (Base Reward): New ETH is minted to reward validators for securing the network under the Proof-of-Stake (PoS) consensus mechanism. This reward, known as the "base reward," is dynamic and is a function of the total amount of ETH staked and the number of attesting validators. The base reward is split between the block proposer and all validators that attest to the block.
• Burning (EIP-1559): The implementation of EIP-1559 introduced a mechanism where a portion of the transaction fee, known as the "base fee," is burned instead of being paid to validators. This burning mechanism reduces the total supply of ETH.
• Net Supply Dynamics: Post-Merge, the network's burn rate is expected to surpass its issuance rate because staking validator rewards are less expensive for the network than the previous PoW mining rewards. As of December 5, 2024, the projected annual issuance of rewards is approximately 703,000 ETH, with an estimated annual burn of about 954,000 ETH, according to monthly usage statistics. This results in a net reduction in the total ETH supply over time.
• Total Supply: As of December 9, 2024, the total token supply of ETH was approximately 120.27 million.

Allocation Mechanism

The initial allocation of ETH occurred through a token sale, but the ongoing distribution is primarily driven by the issuance mechanism rewarding network participants. Unlike many projects with fixed initial allocations for teams, investors, and public sales, Ethereum's ongoing allocation is focused on rewarding validators for network security.

• Validator Rewards: The primary ongoing allocation mechanism is the distribution of newly issued ETH to validators who stake 32 ETH and participate in block production and attestation.
• Fee Distribution: Validators who successfully propose a block also receive the priority fees (tips) associated with the transactions included in that block. These priority fees are not inflationary.
• Slasher and Whistleblower Rewards: A portion of the slashed ETH from misbehaving validators is redistributed as a reward to the validator that proposes the block containing the slashing message.

Usage and Incentive Mechanism

ETH serves as the core utility token of the Ethereum network, driving both economic activity and security incentives.

• Payment and Gas Fees: Native ETH is essential for settling transaction gas fees on Ethereum, which are incurred when a user attempts any transaction, such as interacting with a smart contract.
• Staking and Security: The primary incentive mechanism is Proof-of-Stake (PoS) validation. Users stake 32 ETH as collateral in the Beacon Deposit Contract to run a validator, securing the network and participating in block production.
• Incentive Alignment: Validators are incentivized to act honestly through the promise of ETH issuance rewards and transaction priority fees. Conversely, validators who go offline lose ETH at the same rate as the base reward they would have received, and those who misbehave are subject to slashing, where a portion of their staked ETH is destroyed.
• Wrapped ETH (WETH): Native ETH can be wrapped as an ERC-20 token, WETH, to enable its use within smart contracts and the broader DeFi ecosystem.

Locking Mechanism and Unlocking Time

The locking mechanism in Ethereum is tied directly to the staking process for network validation.

• Staking Requirement: To operate a validator, a user must deposit 32 ETH into the Beacon Deposit Contract. This deposit acts as collateral and is locked to secure the network.
• Unlocking/Withdrawal: Following the Shapella (Shanghai + Capella) hard fork, which went live on April 12, 2023, validators gained the ability to withdraw both the ETH rewards earned and their initial 32 ETH collateral.
• Withdrawal Process: Validators can fully exit the validation protocol and withdraw their staked ETH and rewards. The withdrawal process is permissionless and allows for the release of the previously locked funds.
