Ethereum Foundation Turns Focus To Security, Sets 128-bit Rule for 2026 To Prepare for Institutional Adoption

In a change in priorities, the Ethereum Foundation is no longer developing speed at all costs but instead focusing on security, publishing a new technical roadmap of zkEVMs. The update requires 128-bit provable security to be used in projects prior to using the Ethereum mainnet to enable institutional adoption.

Ethereum Foundation Shifts zkEVM Roadmap To Security

The Ethereum Foundation has announced an enormous change in its technical roadmap of zero-knowledge Ethereum Virtual Machines (zk-EVMs). The Foundation indicated that the approach will change to emphasize more on security and less on speed-at-all-costs development to be passed in order to deploy on the mainnet.

The shift to security comes as Ethereum has made major advancements in the speed department. zkEVM projects have brought proving times to 16 seconds, down from 16 minutes. In addition, Ethereum gas fees have been reduced by more than 45x by zkEVM projects, with 99 percent of Ethereum blocks now proven in less than 10 seconds.

The Foundation, however, cautioned that these advantages have uncovered a more fundamental weak point: most existing zkEVM designs are based on cryptographic conjectures that are not yet proven, and in other cases are being refuted by newly developed studies.

As a result, the Foundation has referred to security as the elephant in the room; they have cautioned that a weaker system of proving would undermine the Ethereum network. Forged proofs may also allow attackers to forge tokens, alter blockchain state, or empty wallets, so cryptographic security is the final line of defense in the system.

The Push Towards Greater Security

The Foundation has responded to this by developing a three-stage roadmap that will operate until 2026. The first milestone is expected in early 2026. It involves teams combining their proof systems with a new security-estimation framework. 

The aim of this is to rigorously quantify cryptographic assumptions of projects on the Ethereum mainnet. Another checkpoint is planned in 2026, which increases the threshold even more, demanding stronger security assurances and restrictions on proof size and architectural transparency. 

The third milestone is a compulsory step towards 128-bit provable security of any zkEVM to be used in development, moving Ethereum in line with cryptographic standards advocated by cryptography bodies.

Ethereum researchers claim that the timing is intentional. With zkEVM architectures starting to stabilize, formal verification and security proofs can be implemented to a greater extent, where the system complexity will not become encrypted.

The Push Towards Institutional Adoption

Ethereum is increasing its institutional strategy alongside the tightening of technical positioning. The Foundation, in its “Ethereum for Institutions,” is making Ethereum production-ready infrastructure to cater for regulated finance. 

By emphasizing validator base, network strength, and privacy technologies, Ethereum looks to mature at a rapid pace. The Foundation cited the high adoption of tokenized real-world assets, where Ethereum remains the market leader, with key financial institutions already putting live offerings on the network. 

JP Morgan recently launched a $100 million tokenized money-market fund on Ethereum. Stronger security will further encourage traditional finance to build on Ethereum, increasing its institutional adoption.
