Coin Circle (120btC.COM) News: On March 14, Ethereum successfully completed the Dencun hard fork, introducing blobs to lay the foundation for Ethereum’s future expansion. On the 28th, Ethereum co-founder Vitalik
Buterin wrote "Ethereum ushered in blobs, where will we go in the future?" 》Writing an article titled "Ethereum" to explain the future development journey of Ethereum. First, he said that with the help of blobscriptions, the number of blobs has increased to a target of 3 per block, and the blob fee has therefore entered a "price discovery mode."

Then, Vitalik said that the key to future expansion of Ethereum relies on supporting data space and data availability sampling (Data Availability).
Sampling, DAS) rollups technology, and the next step is to use "Peer
DAS (conservative version of DAS)" to verify blobs, which can provide some additional expansion capabilities, and more advanced DAS versions will be introduced in the future. At the same time, Vitalik pointed out that the L2 protocol can be improved in four major directions, including data compression, development of optimistic data structures, improvement of execution-related restrictions, and improvement of security.

 Improve the four directions of L2

 Data compression for more efficient use of bytes

Usually a transaction requires about 180 bytes of data space. Through a series of compression technologies, we can significantly reduce this amount of data, ideally to less than 25 bytes per transaction. This kind of compression can greatly improve the efficiency of data storage and processing.

 Optimistic data technique, only use L1 to protect L2 in special cases

Plasma technology allows data to be retained in L2 under normal circumstances and only relies on L1 to ensure security under special circumstances. This can provide the same security as Rollup for some applications. While Plasma cannot protect all assets, Plasma-inspired architectures can protect most assets. Vitalik suggested that L2s that are unwilling to put all their data on the chain should explore this type of technology.

 Continuous improvement execution related restrictions

With the launch of the Dencun hard fork, rollups have become cheaper using the blobs it introduced. For example, the transaction volume of the L2 network Base has surged, but it has also encountered its own internal gas limitations, resulting in an unexpected increase in fees. Vitalik said that this reveals that in addition to the need to expand the data space of Ethereum, rollups also need to expand internally.

He mentioned the direction of improvement, including "parallel processing (rollups can be implemented similar to EIP-648)" and storage, as well as the interaction between computing and storage, which is an important engineering challenge faced by rollups.

 Continuous improvement of security

Vitalik said we are still far from a world where rollups rely solely on code to protect them. Currently, only the following 5 rollups (of which only Arbitrum is full EVM) have reached "Phase 1".

Vitalik said that we need to face this challenge head-on. Although we cannot yet fully trust the complex optimistic or SNARK-based EVM verifier code, we can definitely move forward half way, that is, setting up a safety committee, only under high thresholds (for example, Vitalik proposed 6 -of-8; 9-of-12 adopted by Arbitrum) to change the behavior of the code.

Ecosystem standards need to become stricter and we should only consider projects that reach at least stage one as rollups. After that, we can move cautiously toward the second phase: a truly code-backed rollup, where the safety committee can only step in when the code is "obviously contradictory." One way to achieve this security goal is to use multiple attestation implementations.

 Ethereum moves towards a more comprehensive decentralized platform

To sum up, Vitalik said that as Ethereum transitions from the era of "rapid L1 progress" to a new stage of "L1 progress is still important but more peaceful", application developers are no longer just building prototypes, but building solutions for millions of people. Service Tools. This requires an adjustment in the mindset of the entire ecosystem, transforming Ethereum from a purely financial ecosystem into a more comprehensive independent decentralized technology platform.
