Merge is imminent: explain the latest technical route of Ethereum

The merger is imminent: a detailed explanation of the latest technical route of Ethereum

  • If “The Merge” goes well, sharding will become the main development axis of Ethereum in 2023 and beyond, and its meaning has changed a lot since 2015 when sharding was proposed.

  • After Vitalik proposed the “Rollup-centric Ethereum Roadmap” and Ethereum’s “Endgame”, the general direction of Ethereum changed in fact – “retreat to the background” as Rollup’s security assurance and data Availability layer.

  • Danksharding and Proto-Danksharding are a series of technical combinations in the form of a combination of “discovering problems” and introducing or proposing new technologies to “solve problems”.

  • The time line is extended to the next few years, and the overall value of Rollup will become larger: there is a multi-rollup development pattern on Ethereum, the cross-Rollup infrastructure is highly perfect, and the Rollup ecosystem is highly prosperous—even beyond Ethereum itself.

In the blink of an eye, 2022 is halfway through. Looking back at the Serenity Roadmap proposed by Vitalik in his Devcon speech in 2018, it is easy to find that the development path of Ethereum has changed several times. Compared with the current roadmap, sharding has been given a new meaning, and eWASM is rarely mentioned.

In order to avoid potential fraud and misleading users, at the end of January this year, the Ethereum Foundation announced that it would abandon the term “ETH2”, and instead renamed the current Ethereum mainnet as the “execution layer” that handles transactions and execution. The original ETH2 The term was renamed the “consensus layer” that coordinates and handles PoS.

Merge is imminent: explain the latest technical route of Ethereum

Currently, Ethereum’s official roadmap covers three parts: the beacon chain, merging and sharding.

Among them, the Beacon Chain, as the pre-work for the migration of Ethereum to PoS and the coordination network of the consensus layer, was launched on December 1, 2020 and has been running for nearly 20 months so far.

The Merge refers to the final merger of the current Ethereum main network and the beacon chain, that is, the unification of the execution layer and the consensus layer, marking the official migration of Ethereum to PoS.In the IOSG article “Dawn is approaching: Ethereum merger is close at hand”, we introduced important progress related to the merger: the current Ethereum Ropsten and Sepolia testnet successfully completed the merger, followed by the Goerli merger; if all goes well , meaning we are not far from a mainnet merger.

In this article we will focus on sharding. the reason is:

First, assuming that the mainnet merger can be successfully achieved within the year, then sharding will follow as the main development axis of Ethereum in 2023.

Second, the concept of Ethereum sharding was first proposed by Vitalik in Devcon 1 in 2015. Since then, GitHub’s Sharding FAQ has proposed 6 development stages of sharding (as shown in the figure above).However, with the update to the Ethereum roadmap and the push for the associated EIPs, the meaning and priority of sharding has changed considerably. When we’re talking about sharding, we need to make sure we have a common understanding of what it means.

To sum up the above two points, it is very important to sort out the ins and outs of sharding. This article will focus on the origin, progress and future route of Ethereum’s original sharding, Danksharding and Proto-Danksharding, rather than going into every technical detail. For more details on Danksharding and Proto-Danksharding, please refer to IOSG’s previous articles: “Will Danksharding be the future of Ethereum sharding?” and “EIP4844: The predictable depression effect of L2 transaction fee reduction is about to begin.”

Quick Review

Rollup, data availability, and sharding will be mentioned several times in this post.

Let’s take a quick look back at the basic concepts of the three here.

Merge is imminent: explain the latest technical route of Ethereum

The current mainstream Rollup is divided into zkRollup and Optimistic Rollup. The former is based on proof of validity, that is, transactions are executed in batches, relying on cryptographic proof SNARKs to ensure the correctness of state transitions; the latter “optimistically” assumes that all state transitions are correct unless falsified; that is, a window of time is required to ensure Incorrect state transitions can be detected.

Merge is imminent: explain the latest technical route of Ethereum

Data availability is very important for both zkRollup and Optimistic Rollup. For the former, users can reconstruct all transactions on the second layer based on data availability to ensure censorship resistance; for the latter, all data on the second layer needs to be published without any transactions being hidden. As for the bottlenecks and corresponding solutions faced by the current data availability, they will be mentioned below.

Merge is imminent: explain the latest technical route of Ethereum

Ethereum full nodes store the complete state of the EVM and participate in all transaction verification, which ensures decentralization and security, but comes with scalability issues: transactions are executed linearly, and each node is required Confirming one by one is undoubtedly inefficient.

In addition, as the Ethereum network data accumulates over time (currently 786GB), the hardware requirements to run a full node increase. A drop in the number of full nodes would lead to a potential single point of failure and weaken the degree of decentralization.

Intuitively, sharding is equivalent to division of labor and cooperation, that is, all nodes are grouped, each transaction only needs to be verified by a single group of nodes, and transaction records are regularly submitted to the main chain to achieve parallel processing of transactions (for example, there are 1000 nodes). It turns out that each transaction must be verified by each node; if they are divided into 10 groups with 100 nodes in each group to verify the transaction, the efficiency is obviously greatly improved). The use of sharding not only improves scalability, but also reduces the hardware requirements of a single group of nodes, thereby solving the above two problems.

original shard

Merge is imminent: explain the latest technical route of Ethereum

Image source:

There are 64 shards in the original Ethereum scheme, and each shard has an independent proposer and committee. The proposer is a randomly selected validator who collects transactions and sorts them; the committee is a set of validators (composed of at least 128 validators), randomly assigned to each shard at regular intervals, and verify the validity of the transaction, if 2/3 of the committee votes, call the validator management contract (VMC) to the beacon The chain submits transaction records. Different from the “data sharding” described below, this kind of sharding is also called “execution sharding”.


Before talking about Danksharding, let’s take a moment to understand its background. Personal conjecture, the foundation of the community atmosphere launched by Danksharding mainly comes from two articles by Vitalik. These two articles set the tone for the future direction of Ethereum.

First, Vitalik published the “Rollup-Centric Ethereum Roadmap” in October 2020, proposing that Ethereum needs to support Rollup centrally in the short to medium term. First, the expansion of the Ethereum base layer will focus on expanding the data capacity of blocks, rather than improving the efficiency of on-chain computation or IO operations. Namely: Ethereum sharding is designed to provide more space for data blobs (not transactions) that Ethereum does not need to interpret, just make sure the data is available. Second, Ethereum’s infrastructure is adjusted to support Rollup (such as L2 support for ENS, L2 integration for wallets, and cross-L2 asset transfers). In the long run, the future of Ethereum should be a single execution shard that is highly secure, accessible to everyone, and a scalable data availability layer.

Merge is imminent: explain the latest technical route of Ethereum

After that, Vitalik described the final picture of Ethereum in “Endgame” published in December 2021: block production is centralized, but block verification is trustless and highly decentralized, while ensuring resistance to censorship. The underlying chain provides guarantees for the data availability of blocks, while Rollup provides guarantees for block validity (in zkRollup, through SNARKs; in Optimistic Rollup, only one honest participant needs to run a fraud proof node). Similar to the multi-chain ecosystem of Cosmos, the future of Ethereum will be the coexistence of multiple Rollups – all based on the data availability and shared security provided by Ethereum. Users rely on bridges to move between different Rollups without paying the high fees of the main chain.

The above two articles have basically determined the development direction of Ethereum: optimizing the construction of the basic layer of Ethereum and serving Rollup. The above argument may be based on the idea that since Rollup has been proven effective and well-adopted, “rather than spending years waiting for an uncertain and complex scaling solution (note: referring to the original shard), it is better to pay attention to Focus on Rollup-based solutions”.

After that, Dankrad proposed a new sharding scheme called Danksharding. Below we will split the specific technical composition of Danksharding to understand.


Merge is imminent: explain the latest technical route of Ethereum

Image source:

The background put forward by Proto-Danksharding is that although the Rollup scheme significantly reduces transaction fees compared to the Ethereum main chain, it is not yet ideally low enough. This is due to the fact that CALLDATA, which provides data availability on the Ethereum main chain, still occupies a large cost (16 gas/byte). In the original idea, Ethereum proposed to provide 16MB of dedicated data space for each block in data sharding for Rollup, but the actual implementation of data sharding is still far away.

On February 25 this year, Vitalik and DankRad proposed the EIP-4844 (Shard Blob Transactions) proposal, also known as Proto-Danksharding, which aims to expand the data availability of Ethereum in a simple and forward-compatible way, making it available in Danksharding. Still available afterwards. The proposed changes only happen at the consensus layer, and do not require additional adaptation work by clients, users and Rollup developers of the execution layer.

Proto-Danksharding does not actually perform sharding, but instead introduces a transaction format called “Blob-carrying Transactions” for future sharding. This transaction format is different from ordinary transactions in that it carries an additional block of data called blob (about 125kB), which makes the block actually larger and provides cheaper data availability than CALLDATA (about 10kB).

However, the common problem with “large blocks” is that the requirements for disk space continue to accumulate, and the adoption of Proto-Danksharding will add an additional 2.5TB of storage per year to Ethereum (currently the entire network data is only 986GB). Therefore, Proto-Danksharding sets a period of time (for example, 30 days), after which the blob is deleted, and the user or the protocol can back up the blob data within this period.

That is, Ethereum’s consensus layer only acts as a highly secure “real-time bulletin board”, ensuring that this data is available for a long enough time and giving other users or protocols enough time to back up the data, not by Ethereum Fangfang permanently retains all blob historical data.

The reason for this is that, for storage, the 2.5TB added each year is not a problem, but it is not a small burden on the Ethereum node. As for the trust assumption problem that may be caused, in fact, only one data storage party is honest (1 of N), the system can operate normally, and there is no need for a set of validator nodes (N/2 of N) to store this part of historical data.

So, is there any incentive to push third parties to store this data? The author has not found the introduction of the incentive scheme, but Vitalik himself proposed several possible data storage parties:

1. Application-specific protocols (eg Rollup). They can require nodes to store historical data related to the application. If the historical data is lost, it will cause risks to this part of the application, so they are motivated to do storage;


3. Ethereum’s Portal Network, a platform that provides lightweight access to the protocol;

4. Blockchain browsers, API providers or other data service providers;

5. Individual enthusiasts or scholars engaged in data analysis;

6. Third-party indexing protocols such as The Graph.

Danksharding  Data Availability Sampling (DAS)

Merge is imminent: explain the latest technical route of Ethereum

Image credit:

In Proto-Danksharding, we mentioned that the new transaction format makes the block actually larger, and Rollup also accumulates a large amount of data, which nodes need to download to ensure data availability.

The idea of ​​DAS is: if the data can be divided into N blocks, and each node downloads K blocks randomly, it can verify whether all the data is available without downloading all the data, which can greatly reduce the burden on the node. But what if a block of data is lost? It’s hard to find that a block is missing just by downloading K blocks randomly.

In order to realize DAS, erasure coding (Erasure Coding) technology is introduced. Erasure code is a coding error-tolerant technology. The basic principle is to segment the data, add certain checksums, and associate each data segment. Even if some data segments are lost, the complete data can still be calculated by an algorithm. .

If the redundancy ratio of the erasure code is set to 50%, it means that only 50% of the block data is available, and anyone in the network can reconstruct all the block data and broadcast it. An attacker would have to hide more than 50% of the blocks if they wanted to deceive a node, but as long as multiple random samplings are done, this rarely happens. (For example, assuming 30 random samples of blocks, the probability that these blocks all happen to be hidden by an attacker is

Merge is imminent: explain the latest technical route of Ethereum

Since nodes do not download all data, but rely on erasure codes to reconstruct data, it is first necessary to ensure that erasure codes are correctly encoded, otherwise data cannot be reconstructed with incorrectly encoded erasure codes.

In this way, KZG Polynomial Commitments are further introduced. Polynomial Commitments are a simplified form of a “representative” polynomial, which is used to prove that the value of a polynomial at a specific position is consistent with the specified value, without including all the data of the polynomial. In Danksharding, the verification of erasure codes is realized by adopting KZG commitment.

Of course it would be easy if we could put all the data in one KZG promise, but building this KZG promise, or rebuilding this data once parts of it are not available – both are huge resource requirements. (In fact, the data of a single block requires multiple KZG commitments to guarantee) and also in order to reduce the burden on nodes and avoid centralization, Danksharding further splits the KZG commitments and proposes a two-dimensional KZG commitment framework.

After we solve the above problems in turn, relying on DAS, nodes or light clients only need to download K data blocks randomly to verify that all data is available; in this way, even after the introduction of “large blocks”, it will not Too much burden on the node.

(Note: In particular, the erasure coding algorithm used in Danksharding is Reed-Solomon coding; KZG commitment is a polynomial commitment scheme published by Kate, Zaverucha and Goldberg. It will not be expanded here, readers interested in the algorithm principle can Self-extension. Also, the solution to ensure the correctness of erasure codes is fraud proofs used in Celestia)

Block Proposer and Builder Separation (PBS)

In the current situation, PoW miners and PoS validators are both block builders (Builders) and block proposers (Proposer) – in PoS, validators can use MEV profits to acquire more new validator seats , so that there are more opportunities to realize MEV; in addition, large verification pools obviously have a stronger MEV capture ability than ordinary validators, which leads to serious centralization problems. Therefore, PBS proposed to separate Builder and Proposer.

The idea of ​​PBS is as follows: Builders build an ordered list of deals and submit bids to the Proposer.Proposers only need to accept the list of deals with the highest bids, and no one can know the specifics of the deal list until the winner of the auction is selected.

This separation and auction mechanism introduces the “involution” between the game and the Builder: after all, each Builder has different capabilities to capture MEV, and the Builder needs to weigh the relationship between the potential MEV profit and the auction bid, so that the actual This reduces the net income of MEV; regardless of whether the block submitted by the final Builder can be successfully produced, the Proposer needs to pay the bidding fee. In this way, the Proposer (in a broad sense, the set of all validators, randomly re-selected within a certain period of time) is equivalent to sharing a part of MEV’s income, which weakens the centralization of MEV.

The advantages of PBS in addressing MEV have been described above, and there is another reason for introducing PBS. In Danksharding, the requirements for the Builder are: calculate the KZG proof of 32MB data in about 1 second, which requires a CPU of 32-64 cores; and broadcast 64MB of data in a P2P manner within a certain period of time, which requires 2.5Gbit/ s bandwidth. Obviously validators cannot meet such a requirement.

So PBS separates the two. Proposer still acts as a general validator node, responsible for selecting transaction lists and broadcasting block headers; while Builder, as a special role, is responsible for the above work and building transaction lists.

In October last year, Vitalik proposed a dual-slot PBS scheme (note: each slot is 12 seconds, which is the time unit of the beacon chain), but the specific PBS scheme is still under discussion.

Censorship Resistant List (crList)

Merge is imminent: explain the latest technical route of Ethereum

But PBS also poses a problem, if a certain Builder always bids the highest price (even willing to pay the financial loss) to win the auction, then he actually has the ability to review transactions and can selectively exclude certain transactions from being included in the auction. in the block.

To this end, Danksharding further introduced the anti-censorship list crList (ie Censorship Resistance List) , that is, the Proposer has the right to specify a transaction list, which must be included by the Builder; after winning the auction, the Builder needs to prove that the transactions in the crList have been is included (or the block is full), otherwise the block will be considered invalid.


Merge is imminent: explain the latest technical route of Ethereum

Combining the aforementioned Data Availability Sampling (DAS), Block Builder and Proposer Separation (PBS), and Censorship Resistant List (crList) yields the complete Danksharding. We found that the concept of “sharding” has actually been diluted. Although the name of Sharding has been retained, the actual focus has been on support for data availability.

So what are the advantages of Danksharding compared to the original sharding?

(Dankrad himself listed 10 advantages of Danksharding here, we choose two to explain in detail)

In the original shard, each individual shard has its proposers and committees, which vote on transaction verification within the shard respectively, and all voting results are collected by the proposer of the beacon chain, which is difficult to do in a single shard. Completed within the slot. In Danksharding, there is only a committee on the beacon chain (a generalized validator set, randomly re-selected within a certain period of time), and this committee verifies the beacon chain blocks and shard data. This is equivalent to simplifying the original 64 groups of proposers and committees into one group, greatly reducing the complexity of both theoretical and engineering implementation.

Another advantage of Danksharding is the possibility of synchronous calls between the Ethereum main chain and zkRollup. As mentioned above, in the original shard, the beacon chain needs to collect the voting results of all shards, which will cause a delay in confirmation. In Danksharding, the block and shard data of the beacon chain are uniformly authenticated by the committee of the beacon chain, that is, transactions in the same beacon block can instantly access the shard data. This stimulates the imagination of more composability: for example, the distributed AMM (dAMM) proposed by StarkWare, which can Swap or share liquidity across L1/L2, so as to solve the problem of liquidity fragmentation.

After Danksharding is implemented, Ethereum will become Rollup’s unified settlement layer and data availability layer.

Closing Thoughts

Merge is imminent: explain the latest technical route of Ethereum

In the above figure, we make a summary of Danksharding.

To sum up, we can roughly see that in the next 2 to 3 years, the direction of the Ethereum roadmap is very obvious – around the service Rollup. Although it is still unknown whether the roadmap will change in the process: Danksharding is expected to be implemented in the next 18-24 months, while Proto-Danksharding will be implemented in 6-9 months. But at least we have made it clear that Rollup, as the basis for the expansion of Ethereum, occupies a certain dominant position.

Based on the outlook proposed by Vitalik, here we also propose some predictive thinking and conjectures:

  • One is a multi-chain ecosystem similar to Cosmos. In the future, there will be a multi-rollup competition pattern on Ethereum, and Ethereum will provide them with security and data availability guarantees.

  • Second, the cross-L1/Rollup infrastructure will become a rigid requirement. Cross-domain MEV will bring more complex arbitrage combinations, similar to the dAMM mentioned above, which brings richer composability.

  • Third, the ecological application of multi-Rollup will surpass Ethereum itself. As the positioning of Ethereum takes the second place, as the data availability layer of Rollup, we guess that more applications will be migrated to Rollup (if the second point is true); or at least applied on both Ethereum and Rollup.
