#大户持仓动态 $ETH Ethereum suddenly turned, this move is very significant.

Recently, Ethereum's official announced a major decision: no longer pursuing speed. Instead, all zkEVMs must meet the "128-bit provably secure" threshold by the end of 2026—this is a hard requirement, not a suggestion.

What does this indicate? Many Layer 2 projects, in pursuit of extreme speed, may have been built on some mathematical assumptions that have not been fully validated. It sounds appealing, but from a security perspective, this leaves hidden dangers. An attacker could theoretically forge proofs or tamper with transactions, posing a systemic risk to the entire ecosystem. An ecosystem worth hundreds of billions cannot bear such risks.

What level is "128-bit security" exactly? To put it simply, it is on par with military-grade AES encryption. Using current computing power to crack it would take hundreds of millions of years. This is not just a simple upgrade or iteration; it is about rebuilding the foundation of trust.

Ethereum has laid out a clear timeline:
- By early 2026, all projects will connect to the official inspection tools.
- By mid-2026, a mandatory reach of 100 security lines.
- By the end of 2026, impact 128-bit security while optimizing proof size.

Short-term growing pains are inevitable. Some projects may need to change their architecture, progress may slow down, and some may even fall behind. But in the long run, this decision establishes the strongest moat for Ethereum. Security has become the real competitive advantage, and institutional capital will only dare to enter on a large scale. When security becomes the industry standard, that will be the time when the ecosystem truly showcases its strength.
