Today, Vitalik made a low-key appearance at the Wanxiang Hasheky Hong Kong Summit. The V God’s speech was really neat and there was no red tape. From the beginning, it was $ETH to be delivered and a straightforward narration.Based on this speech, let me talk about my understanding.
All blockchains are rooted in cryptography, and it can be said that cryptography is the real underlying layer.Moreover, in recent years, the theoretical frontiers of cryptography have been developing.The current goal of Ethereum $ETH is to convert cryptography theory into engineering practice.
Friends who have done development know that the more cutting-edge things in the academic world are, the more challenging it is to get directly used in the industrial world, and cryptography is no exception.
The most concerned cryptography frontiers that Ethereum is now:
· ZK-SNARKs
· 2PC, MPC, FHE
· Aggregate signature
· Improve P2P network
For example, aggregation signatures, Bitcoin has actually made similar upgrades in Schnorr upgrades.The BLS aggregation signature upgrade and Schnorr, which are popular with Ethereum, have their own advantages, and it can also make multiple signatures aggregated into one signature very smooth.
A cryptographic achievement can actually be transformed into:
· Make blockchain more private (multiple signing together is conducive to privacy protection)
· Save gas fees (the total sign takes up less space)
· The requirements for equipment are further reduced (easy to verify)
At the same time, V God also mentioned two elements of “academic theory → technological practice”.
First, efficiency.
For example, a very practical problem is that the blocks of the Ethereum main network are 12s intervals, but it takes as fast as 20 minutes to do ZK-SNARKs Proof.
If there can be a lightweight ZK Proof solution that can be fully ZKed in every block, Ethereum will be very private, secure and censor-resistant, and even faster.
Secondly, safety.
As long as it is a human being, it will make mistakes.
No one can guarantee that there are no bugs in their code.
Now, Debug depends on the naked eye, such as the “Safety Commission”
But in the future, you may rely on multi-provers, and in the further future, you may even rely on AI
Under the premise of both safety and efficiency, absorb more cryptography results.Ethereum’s goal is to directly point to the upper limit of cryptography.
After listening to it, I was very excited that what promoted the development of ETH and all other blockchains was the truly cutting-edge technology.
Now, all public chains ranked behind ETH are desperately comparing with Ethereum and trying to find the answer from the competitor Ethereum.
But Ethereum has found the answer in cryptography.This is the real difference between first-class public chains and second-class public chains.
