Recently, zkSync Era's main network went online, and its users have soared, according to the report.Dune According to the data, by the time of publication, the number of single addresses in zkSync Era has exceeded 200,000, and more than 48,000 ETH cross-links have entered the main network of zkSync Era. Encryption researcher francesco writes about the "zkSync Era Mainnet," which BlcokBeats compiled below:

zkSync Era main network online

The launch of zkSync Era marks a historic moment as encryption officially enters the zkEVM era.

For zkSync, the launch of the Era mainnet is the first step in the rollout phase, which can now be considered an Alpha release, and the infrastructure and core pieces are a solid foundation for future growth. Currently, users can cross the bridge to the main network and interact with some of the online items. Specific reference"Arbitrum after the next Heavenly King project ZkSync interactive tutorial"

zkSync features

zkSync allows users to bridge and cash out faster than Optimistic Rollups, which wait 7 days, and in future multi-Rollup eras, users will interact with multiple L2, This faster, more consistent performance from zkSync will be crucial. The zkSync Era security model, which "guarantees Ethereum 100% security", does not rely on fraud proofs or game theory, but is based on "basic mathematical and cryptographic primitives" (zkproofs).

Compared to existing ZKevm, zkSync takes some firm architectural choices, such as their decision to "manage data availability by publishing updates to the storage slots involved in each transaction." This may not make much sense to non-technical people, but it provides some attributes:

Data availability: Free call data

Instead of paying the call data fees for their transaction entry, users will just have to pay the zkproofs (which are cheaper and more favourable). This allows users to have very large transaction inputs and process large amounts of data, which can be important for many use cases.

For example, account abstraction allows the user to submit further authorization, data validation (for example, another signature for the iPhone, additional metadata such as limit orders, etc.) in the transaction.

Data compression

With Optimistic Rollups, the user must update payment data availability for each individual oracle, which is the scarcest resource shared by all Rollups. There is only a limited amount of bandwidth available for data on Ethereum: Rollups must be shared on L 1, regardless of their scalability. But zkSync comes with the ability to pay the final price for a single storage slot at the end of a high-volume transaction.

As a result, users will be able to update the Prophet as often as needed (for example, doing LP on Uniswap, users will make a lot of transactions, but only pay once).

Data extension

Using zkPorter, a variant of the Validium system, where some data does not have to be published on Ethereum, may make sense for use cases where the user only has to guarantee the validity of the Ethereum transaction, but the data is disposable (such as a one-time voting campaign).

zkPorter will allow users to choose between "zkRollup account, features maximum security and 20 times lower fees than Ethereum" or "zkPorter account has stable transaction fees of only a few cents in different security modes", which makes sense for users who make a lot of transactions.

Compatibility with Ethereum

zkSync Era supports source code EVM compatibility. Most projects deployed from the EVM chain do not require changes to the source code, resulting in increased security and fewer errors and bugs -- no new languages or tools are required.

Are deals cheaper on zkSync? Depending on the use case, zkSync will generally have a cost comparable to Optimistic Rollups. For some use cases, the user will be able to pay 0 because the contract will subsidize these transactions, thanks to the account abstraction.

From an economic point of view, this architecture makes sense for some protocols because they will subsidize the contract once for all users because they will be stored again with the same data availability.

What does zkSync offer

- Allowing previously unfeasible use cases through cheaper and faster transactions;

- Cross composability of EVM;

- Instant withdrawal to L 1;

- Unprecedented level of composability between use cases and Rollup.

Why is zkSync different

- Aligned with the crypto community in spirit: "mission driven project", "freedom first" and accelerating mass adoption of encryption;

- Safety first: There is no room for mistakes or burnout, as these can undermine trust;

- Think long term: Building and optimizing things for the future, where development may be slow in the early stages, but with the infrastructure in place, it will bring more traction in the long run.

What are the risks

Because zk is an entirely new technology, it involves basic system risks, such as smart contract risks. Therefore, there must be a risk buffer mechanism, including several layers of security: if something fails, there must be a backup to continue.

These complex systems have inherent risks: it is difficult to predict when, where and in what form risk will arise, which is why the system architecture must be as simple and isolated as possible. Still, it's pretty predictable what could go wrong.

conclusion

zkSync was the first zkEVM to start mainnet, 3 days before Polygon zkEVM;

zkSync further improves the encrypted user experience, as there are still some problems with L 1 and Optimistic Rollups (swapping large sums of money);

ZkSync will slowly become no trust: trust the team from the start, some rely on, after the agreement is ready, the team will introduce a committee of safety, but safety commission is a transitional, served by limiting the powers of the security council to further reduce the trust rely on; It can freeze deal only, not upgrade agreement, so that the community can have a say in the governance, and within the community divided into soft bifurcate mechanism, similar to the etheric fang and COINS.
