Can ZK-Rollups be attacked by the Dark Horse?

Ethereum is facing issues such as chain crashes and high costs as a result of consumer competition, and in the map, the Ethereum team decided to use a rollup to measure.

However, not all solutions are the same. Due to the availability of hot polygons in early 2021, some community members opted out due to technical difficulties. Other rollup procedures typically include trusted rollups and zkRollups (no-fail authentication mechanism). The next important piece of information is the zkrollups mechanism.

In the field of zkrollups, Matter Labs and StarkWare compete with each other, and the solutions released by Matter Labs are zkSync1.0 and zkSync2.0, which are StarkWare's StarkEx and StarkNet counterparts.

Before we understand these solutions, let's look at the principles behind the presentation itself.

As an Ethereum scalability solution, Rollup can package and offload transactions from its own network and send them to the Ethereum blockchain for analysis. A number of changes have been made, allowing for scalability.

The number of transactions completed once the Rollups itself can solve the TPS problem that Ethereum criticized. According to the Ethereum security itself, the number of transactions can increase from 15 to 3000.

When it comes to the differences between best rollups and zkRollups, the first is that zkRollups can provide solutions and privacy through proven technology. female sex. Of course, not all zkRollups take advantage of the proprietary properties of zero-knowledge technology.

At the same time, zkRollups have a stronger market scale than L1. He uses the network to accomplish his old goals.

Then we separate the zk camps.

1. Camp Starkware :

1) Ex fort

StarkWare launched its StarkEx solution on June 20, supporting smart contracts, and the benefits of zkRollup will allow developers to provide users with ETH and similar services when used.

Currently, StarkEx has completed a total of 43 million transactions, and although its own application network has been widely used, the StarkEx network exchange speed has exceeded 9,000 TPS, the exchange rate has reached 18,000 TPS and scalability increased nearly 600 times. . .

StarkEx also provides a SHARP feature that allows you to bundle products from multiple applications into a single product bundle and publish them to Ethereum all at once. However, due to Ethereum export restrictions, the exchange rate of StarkEx's own products may be affected by the restrictions on ETH, and in order to solve this problem, the leaders of the group have also developed a new technology called Validium. This can reduce the application cost and users of this system.

Unlike zkRollups, where the data is contained in a string, Validium publishes the data contained in a string, providing status to further improve performance.

At the application referencing level, dYdX, Immutable X, DeversiFi and Sorare were selected in turn, but dYdX chose zkRollup mode (on-chain data available) and DeversiFi, Immutable X and Sorare were selected in Validium mode (validation off-chain data).

Validium exchange rates are lower than zkRollup After Immutable X acquired the Validium model, Mint and NFT oil exchange rates were $0, while NFT Mint and Ethereum traded between $20 and $50 $. Wait, the same DiversiFi made by Validium also has zero. exchange rate.

2) Starknet

In addition to StarkEx, zkRollup in Validium mode, StarkWare released the next version of zkRollup and released Alpha mainnet. The main feature of StarkNet is the full configurability of the application, that is, it can connect and connect to each other. And StarkEx is unable to gather apps, StarkNet's testnet.

From June 21, we will launch smart contracts and promote onboarding after 2 months. And since StarkNet applications have no distribution rights, anyone can send them over the network as long as they use the same compiler.

StarkNet applications have been extended from Defi to programs such as Devtools and Network Tools. It is believed that the connection of applications on StarkNet will become more frequent as more and more Dapps are sent.

2. Camp MatterLabs

1) zkSync1.0

Matter Labs' first zkRollup scalability solution, zkSync, with the same lower cost as zkRollups above, but not limited to a token payment on the mainnet, other tokens were exchanged or coins were paid for Exchange tokens for as low as $0.2.

To date, the zkSync1 mainnet exchange rate is around $6 million, and the value of TVL is around $26 million. Compared to StarkEx network, zkSync is also a big step forward in terms of TPS, switching and blackout. Location, July zkSync has also added NFT capabilities, including Mint and NFT marketplaces.

2) zkSync2.0

Matter Labs' next assassin, zkSync2.0, will support all smart contracts like StarkNet, and TestNet launched in October 2021. It should be noted that zkSync's Curve Finance Entrepreneurs also led the submission of this application. zkSync2.0 has released zkEVM TestNet, which is used to display ETH smart contracts using zkRollup. Now UniSync has completed the deployment of this testnet.

So far, UniSync has exceeded 60W of market potential from our test network. However, zkEVM is still in the test network phase of the system, so unless the development team's application is registered for free, integration is not possible.

zkSync 2.0 also introduces zkPorter, similar to StarkEx's Validium system, a PoS chain that allows zkSync 2.0 users to post data transfers to zkPorter instead of Ethereum, enabling greater exchange. The Ethereum exchange rate does not apply to zkPorter exchanges, so zkPorter thinks this would be a cheaper alternative.

3. Finally

In terms of authentication mechanism, the verification method of the zkRollups mechanism is better than the authentication method of the optimistic rollup, but it takes longer when the cost of transactions in zkRollups is low compared to the time required for the optimistic rollup to withdraw. L1. The long blocking capacity of the chain must be completed, which means that the time to remove zkRollups must be extended to several hours.

Back in zkRollups, whether StarkWare or Matter Labs, both sides worked hard to learn Ethereum's flawless replay metrics. Although the StarkNet network security is not like that of zkSync series, both in terms of exchange rate and price, in terms of lock volume, zkSync system still needs customers using hardware of entry, but StarkNet is still in the experimental stage. network application already developed On zkrollup network now available, StarEx launched dYdX, a simple and fast application like Diversify, Immutable X, Sorare and more.

As a combination of smart contracts, StarkNet has taken the lead, but in the zkSync series, testnet zkEVM compatible Ethereum smart contracts have also been released. Data availability shares (Validium from StarkWare, zkporter from Matter Labs) have been made available for free by Ethereum tariffs.
