Vitalik Buterin Proposes Three Structural Updates to Strengthen Ethereum Network Security

Source: CryptoNewsNet Original Title: Ethereum Founder Vitalik Buterin Offers Three Proposals That Bring Radical Changes to ETH! Here Are the Details… Original Link: Ethereum founder Vitalik Buterin has released new statements regarding ETH and announced three structural updates that will shape the future direction of the network. He stated that these are deep structural changes that strengthen the network, simplify clients, and prevent all classes of DoS vectors.

Buterin proposed three key changes to minimize Ethereum attack vectors:

1. Limiting the number of contract code bytes accessible per transaction - imposing constraints on code access
2. Imposing a limit on ZK-EVM prover cycles - reducing computational overhead
3. Strengthening the hard limit and overhauling the EVM memory cost structure - improving memory efficiency

Buterin explained that Ethereum has gradually evolved to limit the workload a single transaction or block can handle, and he expects this trend to accelerate.

According to Buterin, these restrictions will reduce Ethereum’s potential attack surface and make the network a simpler, more secure, and predictable system. He emphasized that these changes eliminate entire classes of DoS risks, simplify client code, and create more options for increasing efficiency by imposing various kinds of hard limits on how much can happen within a single block or a single transaction.

The proposed changes include:

• Limiting the number of code bytes accessed (short term: increased cost of calling large contracts, medium term: binary tree + per-piece pricing)
• Limits on ZK-EVM prover cycles (repricing)
• Changes to memory pricing to create a clearer hard limit on maximum EVM memory consumption
