Ethereum (ETH) tokenomikai adatai

The token economics of Ethereum (ETH) have undergone a significant transformation, particularly with the transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS) via "The Merge" and the implementation of EIP-1559. This shift has moved Ethereum toward a potentially deflationary monetary policy, often referred to as "Ultrasound Money," by balancing new issuance with a transaction fee burning mechanism. As of December 9, 2024, the total token supply of ETH is approximately 120.27 million.

Issuance Mechanism

Ethereum's issuance mechanism is now characterized by a dynamic supply model driven by two opposing forces: new issuance (rewards for validators) and burning (transaction fees).

• Proof-of-Stake (PoS) Issuance: Following The Merge, new ETH is minted to reward validators for securing the network and participating in block production. This reward, known as the "base reward," is dynamic and depends on the total amount of ETH staked and the number of attesting validators.
• Issuance Rate: The projected issuance of rewards is approximately 703,000 ETH annually (as of December 5, 2024). This issuance rate is significantly lower than the previous PoW model, which is a key factor enabling the network's deflationary potential.
• Burning Mechanism (EIP-1559): The EIP-1559 upgrade introduced a mechanism where a portion of the transaction fee, known as the "base fee," is permanently removed from the supply (burned) rather than being paid to validators. This mechanism dynamically adjusts the base fee to keep block usage near the target limit.
• Net Supply Change: The projected burn rate is approximately 954,000 ETH per year (based on monthly usage statistics as of December 5, 2024). When the burn rate surpasses the issuance rate, the total supply of ETH decreases over time, leading to a deflationary environment.

Allocation Mechanism

The initial allocation of ETH was highly decentralized, particularly when compared to many newer projects. A historical analysis of initial token allocations for various public blockchains shows that Ethereum had one of the smallest allocations reserved for "Insiders" (Team, Company, and VC investors) at 5%, reflecting a strong focus on decentralization from the start.

While the initial distribution occurred during the network's launch, the ongoing allocation of newly issued ETH is directed entirely toward network security participants:

• Validator Rewards: New ETH is issued as staking rewards to validators who successfully propose and attest to blocks.

Usage and Incentive Mechanism

ETH serves as the fundamental utility token of the Ethereum network, with its usage directly tied to the network's security and operation.

Primary Utility

• Payment for Gas Fees: Native ETH is used to settle transaction gas fees on Ethereum. These fees are incurred whenever a user attempts a transaction, such as interacting with a smart contract.
• Collateral for Security: ETH is used as collateral by validators to secure the network under the Proof-of-Stake consensus mechanism. Validators must deposit 32.00 ETH into the Beacon Deposit Contract to participate.

Incentive Structure

Validators are incentivized through a combination of newly issued ETH and transaction fees:

1. ETH Issuance (Base Reward): Validators receive a portion of the newly minted ETH for proposing and attesting to blocks.
2. Priority Fees (Tips): Validators who successfully propose a block receive the priority fees (tips) associated with the transactions included in that block. These fees are paid by users to incentivize faster transaction inclusion and are non-inflationary.
3. Slashing and Whistleblower Rewards:
   • If a validator misbehaves and is "slashed," a portion of their staked ETH is redistributed.
   • The validator that proposes the block containing the slashing message receives a slasher reward, which is equivalent to the slashed validator’s effective balance divided by 512. This reward is also non-inflationary.
   • Conversely, if a validator is offline, they lose ETH at the same rate as the base reward they would have received.

Locking Mechanism and Unlocking Time

The locking and unlocking mechanisms primarily relate to the staking process for network validators.

Locking Mechanism

• Validator Staking: To become a validator, a user must lock 32.00 ETH into the Beacon Deposit Contract. This deposit serves as collateral against dishonest behavior.
• Permissionless Operation: Operating a validator is permissionless, requiring the 32 ETH deposit and running the necessary client software.

Unlocking Time

• Withdrawals: Following the Shapella (Shanghai + Capella) hard fork on April 12, 2023, validators gained the ability to withdraw their earned ETH rewards and fully exit the validation protocol to withdraw their initial 32.00 ETH collateral.
• No Fixed Lock Period: Unlike some other staking mechanisms that require a fixed lock duration (e.g., one week to four years for Curve's veCRV or one week to two years for Pendle's vePENDLE), Ethereum's staking mechanism allows for withdrawals after the Shapella upgrade, though the process of exiting the validator set and withdrawing funds is managed by the protocol and subject to network queue times.
