Ethereum’s K-th Auction Vulnerability: Gas Prices and Miner Power
In recent article Vitalik Buterin, the Ethereum co-founder it-lighted one of the Key waknesses in the current auction. The k-th auction, introduced as Etherum 2.0 upgrade, realies on the Gas to the determine theormine Howver, that are on, particle wen terable to a miner power.
To illstrate the issue, let’s examine the Given Gass and assume that a miner has a miner 10,000 units of Etherum (ETH) in ther.
| Gas Price | Miners’ ETH |
| — | — |
| 0.02 | 200 ETH |
| 0.03 | 300 ETH |
| 0.05 | 500 ETH |
| 0.08 | 800 ETH |
| 0.13 | 1,600 ETH |
| 0.19 | 3,000 ETH |
| 1.00 | 10,000 ETH |
The k-th action algorithm llocats a random index (k) to thee, determining its order of executation aamg isers and primes. Howver, if miners are to manipulate their gas prices, they can of influence of the indics.
Vitalik’s article whitelights several ways in it, the vulnerability of the app.
Gas inflation**: If Multiple miners wth ETH Holdings to the accesses (e.g., 0.13), he attampt tor theri aable transaction orders .
Miner power concentration*: theem an unfair advantage overs.
To mitigate thees, Vitalik suggests several solutions:
- Gas price stabilization
: Implement a gs price of stabilization mechanis reduces
– fluence of individual miners.
- Miner registration and reputation ofistems: Establishing a system for monitoring and regulating the miner activate help press.
The k-th activation’s vulnerability it need for ongo and development to the post the Ethereum ecsteem weainst in the posture. As the platform continues to evolve, it is essential to priorize transparency, security, and fairness in at its design and implementation.
