Leo, BlockBeats

Many terrible events have happened in Crypto 2022, exposing macro industry defects and making us nervous in the cold winter. However, we cannot be taken away by some "bad guys". crypto not only has economic ups and downs, but also technological innovation and progress, such as ZK-rollup. As a technology that V God is very optimistic about, ZK technology has made a great leap forward in 2022. Cinchchilla, an encryption enthusiast, sorted out the article "Visualization of this year's popular ZK-Rollup and related projects", and BlockBeats compiled it as follows:

Zk-rollup is one of the most promising innovations in cryptocurrencies, but it's easy to get confused with some of the new solutions that have emerged recently. This article will list some of the popular ZK protocols, along with the related combing.

A brief introduction before we begin: ZK-rollup is a layer 2 extension solution that improves Ethereum throughput by processing off-chain transactions and bundling them on the chain. Without going into the technical details here, remember what V said, the benefits of ZK-rollup include lower Gas and higher on-chain security.

Next I'll cover a few different protocols with similar names and topics.

zkSync

zkSync is an EVM-compatible ZK-rollup protocol, and while it's still under construction, the team has already launched Mainnet, where it can be played out. In addition, zkSync has raised $458 million and has yet to issue tokens.

L2BEA And Ethereum Daily To share:

-zkSync with $53 million TVL;

- according to the Orbiter Finance (https://twitter.com/Orbiter_Finance), L2 zkSync it is the third trade agreement;

- To date, at least 300 projects have joined its ecology.

The image below shows Ethereum Daily's growing ecosystem.

StarkWare

With ZK-rollup solution, StarkNet is probably zkSync's biggest competitor, zkSync has launched mainnet, but Starknet is still available for trial on beta network, again without token, click Understand StarkNet Airdrop Guide.

L2BEAT And Ethereum Daily To share:

-Starknet has 4.6 million TVL;

- More than 200 projects have been added to the ecosystem;

- The team has raised a total of $273 million to date.

The following figure is odin-free.stark The growing ecological view of StarkNet is displayed.

zkLend

zkLend is not a ZK-rollup, but a Layer 2 money market protocol built directly on StarkNet. It is currently in beta, with a version of Artemis, where you can try Argent or Braavos wallets for lending. zkLend also has no token.

zk.money

zk.money is a privacy-focused ZK-rollup DeFi service based on Aztec network. It can already connect to assets with Dapps such as Aave, Yearn and Lido, focusing on privacy services.

Aztec network Is a privacy-oriented ZK-rollup protocol whose product is fully operational and whose main goal is to provide transparency to the protocol and privacy to users. Aztec has just completed a $100 million Series B funding round. Neither Aztec nor zk.money has issued a token.

Polygon ZK

In addition, Polygon is also building a Zk solution that is equivalent to an EVM by creating it in source code, which is currently available on the beta web, as shown below.

ZKSpace

ZKSpace is a ZK-rollup platform that consists of:

-ZKSwap, L2 AMM Dex;

-ZKSquare, a payment service;

-ZKSea, NFT Market.

Below is the real asset TVL of its ecology.

Scroll

Scroll is layer 2's zkEVM, their goal is to have A scalable network with native compatibility of the Ethereum protocol, to try out their test network, Scroll closed a $30 million Series A funding round in April, but doesn't have a token yet.

While these are the most popular protocols, we should not forget that other projects are also building ZK-rollup solutions, for example, the layer 2 protocol Loopring . Click to learnOther ZK-rollup.

As I said at the beginning of this article, I didn't delve into the technology behind layer 2, but if you're confused when you hear all these Zk words, it's normal. Here are two important concepts to help you get down to basics.

zkSNARK and zkSTARK

These are two different mechanisms that can be used to calculate and verify transactions, and are basically the concepts that underpin the two different types of ZK-rollup,Permissionlessness.ETH A detailed introduction was made.

In summary, the purpose of this article is to provide an overview of the current state of ZK-rollup, which may be useful for you to discover new protocols, learn about them, or interact with (before possible airdrops).
