Ethereum Cancun upgrade is coming: taking stock of favorable tracks and 20 projects

Author: Xiyou, ChainCatcher

February 1 , Cointelegraph reported that Ethereum developers plan to determine the mainnet launch date for the Dencun upgrade on February 8. In a Reddit community post, Ethereum core developer Tim Beiko said that the recent Cancun upgrade test went smoothly, the Sepolia testnet upgrade on January 30 was also successful, and the final Holesky testnet upgrade was carried out as scheduled on February 7 .

Christine Kim, vice president of research at Galaxy Digital, said that there is an 80% chance that the Dencun mainnet will be activated by the end of March.

As the Cancun upgrade approaches, which tracks and events will benefit from the dividends brought by the Dencun upgrade?

According to the previous article "One article to understand what performance of Ethereum will be improved by the Cancun upgrade?" 》, a major core of Dencun upgrade is to reduce the cost of L2 publishing data, and will drive the demand for Infra tracks such as decentralized storage, DA and RaaS.

L2 network and its ecology

Dencun upgrade is the most direct One of the positive tracks is the L2 track. The introduction of the Blob data format allows L2 transaction fees to be reduced by one thousandth of the original. Lower expenses and better performance will not only attract more users, but also promote Its network ecosystem is prosperous.

Optimistic Rollup is the 7 major networks

1. TVL breakthrough on Arbitrum chain 10 billion US dollars, vertical expansion through Orbit L3 stack

Entering 2024, the value of crypto assets locked on the Arbitrum One mainnet chain has exceeded 100 billion US dollars, now US$10.5 billion. According to L2Beat data, on February 1, Arbitrum One’s on-chain TVL market share accounted for 49.8%, and it has always maintained the first place among many Layer 2 projects for a long time.

According to Dune data, as of February 1, the total ETH storage value (TVB) bridged by the Arbitrum official bridge was 3.354 million pieces, and Optimism during the same period The total value of official bridged ETH is 320,000 pieces, zkSync is 2.975 million pieces, and Starknet is 860,000 pieces.

The market value of the native token ARB is US$2.17 billion, ranking 41st among crypto assets.

On January 31, the Arbitrum community initiated a proposal to implement the ArbOS20 version to support most improvements in the Dencun upgrade, including leveraging EIP4844 at a cheaper price. The ability to publish L2 transaction batch data in Blob form on L1 Ethereum, etc. The ArbOS20 upgraded version will support any Arbitrum chain based on L1 Ethereum and its applications on the chain. No modification or action is required to obtain the benefits of the Cancun upgrade.

Arbitrum official ecological portal page Portal statistics show that there are 689 ecological projects included, covering cross-chain, DeFi, infrastructure and tool products, and games , NFT, etc., representative applications include decentralized perpetual contracts GMX and Hyperliquid, multi-chain lending Radiant, native DEX Camelot and Metaverse game ecosystem Treasure, etc.

Regarding ecological development, on January 20, the Arbitrum Foundation announced the launch of the second phase of the funding plan to provide financial support to builders. Grants issued through this plan It will be used to improve Arbitrum adoption and create a stronger technical structure to build sustainable communities within the Arbitrum ecosystem.

Subsequently, Mozaic, a revenue strategy platform supported by blockchain game The Beacon, token management tool Collab.Land, and LayerZero, announced that it has received funding from the Arbitrum Foundation.

In addition, Arbitrum is also attracting projects and developers through the Orbit technology stack plan. According to Offchain Labs co-founder Steven Goldfeder, there are currently more than 50 Arbitrum Orbit chains under development, and it is predicted that there will be 150 Orbit chains on the mainnet in 2024.

On January 16, Arbitrum announced the launch of the Arbitrum Orbit expansion plan, which supports developers to build their own L2 or L3 and settle directly to Ethereum or other Ethereum L2. For example, Optimistic ollups, ZK-Rollups and other networks.

At the end of December last year, the Xai network based on Arbitrum Orbit technology and designed specifically for games announced an airdrop of tokens XDAI to community users, causing users to pay attention to the Arbitrum L3 network. sought after.

Spurred by expectations of airdrops, the network TVL has attracted more than $1.33 billion in funds as of February 1 since its launch on November 21 last year, and has received $20 million in financial support from Paradigm and Standard Crypto.

On January 17, Blast announced the launch of the test network and simultaneously launched the "Big Bang" airdrop competition. Developers participating in the competition will have the opportunity to receive airdrop tokens. Coin rewards, thus attracting a large number of crypto enthusiasts.

However, on February 1st, former EVM engineer @0xKaden posted an article stating that he found a problem with Blast's code base, plagiarized Optimism's code, and also removed Optimism's code. The MIT license changes to BSL, and Blast intends to fork the Optimism code base.

6. Decentralized sorter Metis

Metis Network (Metis for short) was originally a Layer 2 expansion network based on Optimistic Rollup technology. In July last year, it announced that it would be upgraded to a Hybrid Rollup solution, and by introducing innovative technologies such as decentralized sorter pools and... Unique among Layer2 networks.

The so-called decentralized sorter, Metis, has introduced a PoS sorting pledge pool, and users can become sorter operating nodes by pledging the token METIS. Currently, if you want to become a Metis sequencer node, you need to pledge 20,000 METIS tokens, worth approximately US$1.6 million.

Currently, in the mainstream L2 Rollup solution, the Sequencer is responsible for receiving transactions from users, processing them off-chain, and generating a batch of compressed The orderly transaction is then sent to Ethereum.

However, L2 network sorters such as Optimism and Arbitrum mostly operate in a centralized manner. Although they are low-cost, they are prone to MEV gray due to their responsible sorting functions. Income, the sorter obtains additional income by disrupting or preempting transactions, or by prioritizing transactions with high Gas, making transactions no longer decentralized, or a single sorter being attacked affects the entire network.

Metis expands the number of sorter nodes through the sorter pool to increase competition and transparency, and then introduces a consensus algorithm to disperse rights and eliminate the risk of single control in technology. Thereby improving the decentralization of the sorter.

On January 16, community testing of the PoS sequencer pool was launched on the Metis Sepolia testnet and will be officially released on the mainnet later in 2024.

In December last year, the MetisDAO Foundation launched the US$100 million Metis Ecological Development Fund (Metis EDF), which will allocate 4.6 million METIS for sequencer mining. , retroactive funding, new project deployment, etc. to accelerate the development of its ecosystem.

As of February 1, the crypto assets locked by Metis Network TVL were worth US$667 million, ranking among the top five in the Layer 2 market. The token METIS is quoted at US$78.4, with a market value of US$410 million, ranking 140th.

7. Modular L2 network Mantle Network

Mantle Network is an Optimistic Rollup modular Layer 2 expansion solution incubated by BitDAO. It was launched on the test network Sepolia on January 12.

In Mantle, the main network provides the execution layer, consensus and settlement are in L1 Ethereum, data availability is sorted out by the dedicated Mantle DA layer, and is served by modular data Eigenlayer provides underlying technical support. This form of division of labor and cooperation is more conducive to improving efficiency on the chain.

On December 4 last year, Mantle announced the launch of the liquidity staking protocol Mantle LSP on the Ethereum mainnet, entering the LSD track. Users can pledge ETH through this product to obtain The Ethereum PoS network benefits and obtains the liquidity staking certificate mETH, which is the second core product in the Mantle ecosystem.

As of February 1, the number of ETH pledged by Mantle LSP is approximately 339,000, worth US$810 million.

Since last June, zkSync announced the launch of ZK Stack, a component for building customized zkRollup systems L2 and L3 (also known as HyperChain), the zkSync ecosystem has There are ZkSync Era main network and L2 or L3 network based on ZK Stack.

On January 31, Omar, head of zkSync developer Matter Labs BD, issued a proposal in the TreasureDAO community, hoping that Treasure Chain would use ZK Stack as L2 and use L3 chain Expand vertically. In addition, Matter Labs said it is working with the zero-knowledge proof research Lambda Class team so that the ZK Stack chain can have its own native Gas token, and the Treasure Chain can use MAGIC or any other ERC-20 as the Gas token.

Regarding the ZkSync Era main network, there are 96 ecological applications included in the DeFiLlama data platform. Representative products include DEX platform Mute.io, Velocore, and lending application ZeroLend. Derivatives protocol Rollup.Finance. Among them, on January 30, the lending protocol ZeroLend announced the issuance of airdrops to Pyth Network oracle pledgers.

However, during the outbreak of the public chain Inscription in December last year, the zkSync Era network performance did not withstand the test. It was reported to be down on December 15. No block has been produced for 2 hours.

2. Starknet

January 31, Starknet On-chain data released by core developer @antiyro on social media shows that there have been transactions on the Starknet network using STRK to pay gas fees. On February 1, the Starknet ecological smart contract wallet Braavos has listed STRK tokens by default. Community users have speculated that this is Starknet’s test preparation for the issuance of token STRK.

Prior to this, the Starknet main network completed the v0.13 upgrade on January 10, which can significantly reduce costs through more efficient transactions, and is also responsible for using STRK to pay fees technical preparations.

In terms of application chain, on January 20, Starknet posted on social media that it would cooperate with the modular DA layer Celestia to achieve high throughput Layer3 network .

As of February 1, the TVL on the Starknet chain is US$140 million, and there are 18 included applications. Representative applications include DEX platforms JediSwap and mySwap, and lending applications. zkLend, derivatives trading protocol ZKX, etc.

3. Polygon zkEVM

As of February 1 , the TVL on the Polygon zkEVM chain is US$116 million, ranking 13th among many Layer2 networks.

Compared to the mediocre on-chain ecosystem, the Polygon CDK development stack performs quite well.

Since the announcement of the launch of the chain development kit CDK for developing and connecting Ethereum L2 in August last year, many well-known projects have developed Layer2 based on its technical architecture. network.

Including ZKFair, a community-driven network that has been popular on social media recently, which is a ZKRollup built on Polygon CDK and Celestia DA technology; transferred from OP Stack halfway Manta Pacific.

On January 30, the game public chain Immutable stated that the zkEVM mainnet launched in cooperation with Polygon will be open to the public in the next few weeks.

In December last year, the Indian e-commerce company Flipkart announced that it would build an L2 network based on Polygon CDK to expand its Web3 loyalty program; in November last year, OKX announced a partnership with Polygon Cooperate to launch zkEVM L2 network X1; in October last year, Polygon Labs Lianchuang also proposed that ApeCoin DAO use Polygon CDK to develop its L2 network ApeChain, etc.

At present, Polygon 2.0 is an L2 layer multi-chain network ecosystem driven by ZK technology, including zkEVM, PoS and L2 network built based on CDK.

On January 28, Polygon zkEVM stated on social platforms that it plans to upgrade Etrog. This upgrade will make Polygon zkEVM a Type2 zkEVM (fully equivalent EVM ), enabling developers to deploy code on Polygon zkEVM with an Ethereum-like experience.

On February 1, Marc Boiron, CEO of Polygon Labs, the developer of Polygon, issued a statement stating that 60 people, accounting for 19% of the team members, had been laid off.

4. Linea, ConsenSys’ Ethereum L2 solution

According to Dune data, as of February 2, the number of ETH bridged on the Linea main network is close to 380,000, and the number of interactive addresses reaches 418,000.

On January 28, Linea posted on social media that users who had participated in its DeFi Voyage event, if they completed the transaction on the identity certification platform Verax before January 22, For Proof of Humanity (PoH) personal identity verification, SBT soul token LXP (Linea Voyage XP) will be airdropped to the wallet.

In December last year, Linea announced the Linea Voyage XP (LXP) ecological incentive plan, which will issue non-transferable SBT tokens LXP to users participating in the DeFi Voyage event. In recognition of the community's contribution to the development of the Linea ecosystem.

5. Scroll

Since it was announced in October last year Since the mainnet, the value of crypto assets locked on the Scroll chain (TVL) has increased to US$63.8 million, and the total value of ETH bridged by the official cross-chain bridge Scroll Bridge has exceeded US$138 million.

On January 2, Scroll co-creator Sandy Peng released the 2024 roadmap. Scroll plans to reduce cross-chain costs by 50%, with the help of EIP-4844 Blob. Transaction fees, adding multiple validators, adding decentralized proofs and parallel EVM, etc.

In a public speech on December 27 last year, Sandy Peng said that basically all the tools needed by developers such as Chainlink, The Graph, and RPC have been online. Some of the Ethereum ecological projects that everyone is familiar with will gradually be deployed on Scroll. At the same time, the focus of development in 2024 will also tend to be native projects on Scroll. Next year, ecological projects will be encouraged to do more Fair Launch to support fair community participation.

Data availability layer DA and storage track

Dencun upgraded core module EIP-4844 , the Blob data storage format is introduced in the process of L2 data submission to L1, which is to build an exclusive channel for L2 transaction data to be uploaded to the L1 main network, allowing Ethereum to carry more data, improving Ethereum's TPS and reducing costs. However, the data storage of Blob is not permanent, it is just a temporary data package, which will be cleared or discarded periodically (currently 18 days).

Since Blob data can only be saved for a short period of time, there are problems with calling historical data, and this part of the data still has the potential to be called and analyzed.

Therefore, the storage of this part of data will also drive the demand for decentralized storage business. Among them, the modular data availability layer DA can achieve lower storage costs. Providing programmable L2 data solutions also ensures that on-chain data can be used and accessed by all network participants, and after the EIP-4844 upgrade, the cost of data availability can be further reduced to the original five to ten times. one part.

DA layer project representative

DA layer leading project Celestia

Celestia is a PoS network based on CometBFT and Cosmos SDK. It is also a modular blockchain project focusing on data availability. It deconstructs the blockchain into consensus layer, execution layer, data availability layer, etc. through a modular architecture, completes their respective tasks through division of labor and cooperation, and improves network performance and efficiency.

The DA layer mainly consists of two functions: data availability sampling (dataavailabilitysampling, DAS) and namespace Merkle trees (Namespaced Merkle trees, NMT).

The former DAS allows light nodes to still verify data availability without downloading the entire block; the latter NMT allows the network to classify data into different This selective data retrieval makes Celestia more efficient and scalable, especially for applications that require only a specific selection of blockchain data.

Currently, Celestia has become the preferred data solution for developers when building L2 networks.

Among them, Polygon CDK, OP Stack, ZK Stack and other L2 network developer stacks have integrated its technology. When building their own L2 network, developers can Use Celestia directly as the data availability layer.

On January 30, Starknet announced a cooperation with Celestia to build an L3 network. In addition, Manta Pacific is also a representative L2 network based on Celestia.

Avail

Avail was originally Polygon Labs in 2020 A project founded to solve data availability problems, but in March last year it separated from Polygon and ran as an independent DA public chain, no longer limited to Polygon or Ethereum.

Avail can efficiently sort and record transactions, provide data storage and verify data feasibility, etc.

In November last year, Avail announced the opening of the incentivized test network "Clash of Nodes", inviting existing validators from the Kate test network to incentivize validators and light customers. End operators test, verify and operate to earn points and potential rewards.

EigenDA

EigenDA is based on the Ethereum re-pledge protocol The decentralized data availability layer DA developed by EigenLayer provides technical support for the data availability layer of the modular L2 network Mantle.

Different from general DA projects Celestia and Avail, EigenDA is a middleware. It does not have its own consensus mechanism, and its security is through EigenLayer’s Ethereum The validator obtains it through re-staking mode.

At the same time, EigenDA is also the first active verification service (AVS) on EigenLayer. Re-pledgers re-pledge ETH into EigenDA to perform data verification services to obtain rewards. , L2 publishes data to EigenDA, resulting in lower transaction costs and higher TPS.

In November last year, EigenLayer announced the second phase of EigenDA test network. Operators can register to the network and start verifying EigenDA; Restakers can stake their Delegate to an Operator and start using shared security with EigenDA; as a Rollups developer, you can integrate EigenDA as a data availability layer.

On December 5 of the same year, EigenDA announced the launch of the partner program. The first batch of participants has 8 networks using EigenDA to achieve data availability, namely AltLayer , Caldera, Celo, Layer N, Mantle, Movement, Polymer Labs and Versatus.

NearDA

In November last year, the Near Foundation announced Launched data availability solution Near DA. It is reported that publishing data on Near DA may be about 8,000 times cheaper than publishing data directly on Ethereum. Initial users include Starknet’s Madara, Caldera and Movement Labs.

On January 19, Near DA stated that it had integrated with Polygon CDK for developers to build Ethereum ZK Rollups. Prior to this, on December 21 last year, Near DA announced that it had integrated with Arbitrum Orbit.

Data storage track

Ethereum L2 data storage project ETHStorage

ETHStorage focuses on solving the dynamic storage problems of Ethereum and is positioned as the first storage L2 of the Ethereum ecosystem.

On the basis of Ethereum’s data availability DA, ETHStorage can provide programmable storage L2 solutions at a lower cost, which will greatly reduce the cost of Ethereum’s data availability. On the storage overhead of large amounts of data, programmable storage can save 100 to 1,000 times the cost when it is expanded to hundreds of TB or even PB levels.

In July last year, the Ethereum L2 data storage project EthStorage completed a US$7 million seed round of financing at a valuation of US$100 million.

Decentralized data infrastructure Covalent

Covalent provides The Blockchain Indexer service provides developers with a unified API for retrieving blockchain data, allowing developers to reuse queries on multiple blockchains. It extracts data from various blockchains, uploads this data to a storage instance, indexes and transforms the stored data objects, and loads the data into a local data warehouse that is queried by API users.

In November last year, Covalent launched the Ethereum Wayback Machine (EWM) to solve the long-term data availability problem and use it for long-term storage of Blobs discarded L2 status data. In addition, Covalent will integrate L2 data into its existing decentralized data analysis infrastructure services, going beyond simple storage.

In addition, there are established decentralized storage projects such as Filecoin, Arweave, Storj, and BNB Greenfield on the storage track.

LSD and heavy pledge track

In addition to reducing the cost of publishing L2 data to L1 In addition, the Dencun upgrade also introduces EIP-4788, which can place the block root of the Ethereum beacon chain into the execution layer EVM main network, so that the EVM layer of the Ethereum main network can directly read the data consensus status on the beacon chain, and There is no need to rely on third parties to transfer information and data, eliminating the impact of external failures, etc.

EIP-4788 enables the smart contract on the Ethereum execution layer EVM to directly read key ETH balances and statuses pledged in the validator on the beacon chain. Data, improving security and fund utilization.

Simply put, liquidity staking protocols such as Lido, Rocketpool, Swell and other re-staking protocols deployed on the EVM layer, as well as re-staking protocols such as Eigenlayer, can be directly obtained from the consensus layer accesses key data such as validator balances and status, reducing trust assumptions in previous re-staking and improving its operational efficiency.

EigenLayer

According to EigenLayer official website information, on February 2 On that day, the number of ETH pledged in EigenLayer was approximately 460,000, worth approximately US$1.1 billion.

EigenLayer supports re-pledge of LST assets to obtain staking income other than Ethereum PoS, such as staking in other side chains, oracles, middleware, etc., as a node And get verification rewards, so that third-party projects can enjoy the security of the ETH main network, and ETH pledgers can also get more benefits.

Currently, EigenLayer supports Lido’s stETH, Rocket Pool’s rETH, Swell’s swETH and other LST assets.

On February 6, EigenLayer will add three new LSTs, including Frax Ether’s sfrxETH, Mantle Staked Ether’s mETH and Liquid Collective Staked Ether’s LsETH.

In addition, there are many re-pledge protocols based on EigenLayer. For example, a US$3.2 million seed round of financing was completed on January 16, which is not affected by EigenLayer. Renzo, a re-pledge protocol constrained by LST deposit limits.

On January 22, the multi-chain income protocol Magpie announced its integration with the Ethereum re-pledge protocol EigenLayer, and established the SubDAO organization Eigenpie to provide re-pledge services.

RAAS service provider

With Polygon CDK, OP Stack, ZK Stack and other Rollup The launch of network development components allows developers to quickly deploy L2 networks with one click through simple and easy-to-use tools or even code-free form.

However, faced with numerous L2 Stacks solutions, how developers choose the optimal solution has become an important issue that needs to be solved urgently. Rollup as a Service (RaaS for short) Service providers have emerged as the times require. They can not only help developers find the most suitable L2 Stack according to their own needs, but also provide related chain building or related supporting facilities, so that projects can focus on building products rather than infrastructure.

Deploying L2 or L3 is becoming increasingly easier with Rollup-as-a-service providers such as Caldera, AltLayer and Conduit.

Conduit focuses on Optimism ecology

Conduit is focused on Optimism ecology Optimism Rollup's RAAS platform can help developers quickly build L2 based on OP Stack, and has successfully built OP-based Rollup L2 networks such as Zora Network, Aevo, Lyra, and Orderly Network.

In September last year, Conduit added support for Arbitrum Orbit, allowing developers to quickly deploy L2 or L3 on Arbitrum, and helping Parallel Network successfully build Arbitrum’s L2 Rollup.

In March last year, Conduit received a US$7 million seed round of financing led by Paradigm.

Caldera

Caldera is also built based on OP Stack RaaS service provider supports developers to quickly build an OpL2 in a code-free manner.

Caldera is more like a one-stop service platform for Rollup development, providing project parties with all the tools and resources needed to build OP Stack or Arbitrum Orbit framework. Caldera Chains.

In addition to L2 itself, Caldera is also equipped with a series of blockchain infrastructure, such as blockchain browsers, test network faucets, etc., thereby further reducing The cost and usage threshold of the chain are plug and play.

Among them, L2 networks such as Loot Chain, Manta Pacific, and Rari Chain are all built with technical support provided by Caldera.

In September last year, Caldera received a US$9 million seed round of financing led by Sequoia Capital and Dragonfly.

Restaked Rollups service solution Altlayer

Altlayer supports developers to deploy L2 without code, developers You can quickly create a Rollup chain with simple graphical interface operations.

The current flagship product is Restaked Rollups combined with EigenLayer's re-pledge service, which uses EigenLayer's Active Verification Service (AVS) to enhance the security of the Rollup public chain.

On January 17, Binance new currency mining launched AltLayer (ALT).

ZK-based RaaS solution Lumoz

Lumoz was formerly known as Opside , is a RaaS solution built based on ZK, which allows developers to quickly deploy a ZK-Rollup or generate a customized zkEVM application chain through simple front-end operations without knowing any ZK-related knowledge.

ZKFair, the recently popular Layer 2 network, is one of the ZK series L2s built on Lumoz.

In April last year, Lumoz received a US$4 million seed round of financing led by Web3.com Ventures and participated by NGC Ventures and others.
