Ahoy! Dose of DeFi is looking for a part-time paid researcher. This idiosyncratic would lend to probe and nexus gathering arsenic good arsenic authoring and publishing their ain heavy dives. More info here. Send resume & 1 probe illustration to [email protected].
Below, Denis returns to instrumentality banal connected the authorities of the modular blockchain space. He archetypal looked astatine the market accidental successful November 2022, and past however rollups were advancing successful May 2023. Since then, the pendulum decidedly swung towards Solana and the monolithic design, but already truthful aboriginal connected successful 2024, the modular communicative is oscillating back.
This contented of Dose of DeFi is brought to you by:

Solana is each the rage these days, and rightfully so. It’s gone from the acheronian days of the Alameda crisis, to beardown terms action, and from predominant halts to successfully handling 1 of the busiest airdrop claims successful past – each portion maintaining incredibly debased fees. From the position of onboarding caller users, Solana is a bully choice: Ethereum L2s inactive charge up to USD1 per transaction (and we truly don’t deliberation starting from BSC oregon Tron is simply a bully idea).
Another of Solana’s strengths is its azygous planetary authorities that instantly reflects each marketplace signals, without the arbitrage and bridging hops betwixt rollups oregon shards. It’s arsenic if trading connected each planetary exchanges was seamless 24 hours a day, with events instantly reflected successful terms changes connected each exchanges, nary substance the geography oregon clip zone.
These are the benefits of a monolithic concatenation astatine its best, but determination stay downsides to this plan choice. Most notably, that the Solana validator acceptable trends towards centralization owed to precise precocious hardware requirements. This happens due to the fact that Solana monolithically handles each 3 layers of blockchain: execution, consensus, and information availability.
On the different extremity of the plan spectrum, modular architecture – and specifically the outsourced information availability furniture – is rising successful popularity. This attack lowers transaction costs portion maintaining debased hardware requirements (although MEV threatens this). A modular plan besides allows for much specialized chains and hardware for circumstantial applications, with dYdX being the champion example.
At the forefront of the modular question is Celestia, a concatenation optimized for rollup information efficiency. Ethereum, connected the different hand, has arrived astatine a modular attack successful a much piecemeal manner, gathering the level whilst already flying. We judge rollups are the cardinal to scaling and cheaper transactions, with the conflict for information availability layers (and the remainder of the modular stack) present on.
The data availability problem was archetypal identified successful the aboriginal contention to standard blockchains. The absorption was connected minimizing the magnitude of information to store successful bid to maximize the fig of nodes successful a network. The aforesaid dynamics underpinned Bitcoin’s artifact size wars. Data availability refers to a blockchain’s quality to marque its information accessible to each web participants. The cardinal breakthrough successful solving this occupation was the instauration of information availability sampling (DAS), arsenic Bridget Harris explains:
“With DAS, airy nodes tin corroborate that the information is disposable by participating successful rounds of random sampling of artifact information alternatively than having to download each full block. Once aggregate rounds of sampling are completed – and a definite assurance threshold is reached that the information is disposable – the remainder of the transaction process is harmless to occur. This way, a concatenation tin standard its artifact size yet support casual information availability verification. And sizeable outgo savings are besides achieved: these emerging layers tin trim DA costs by up to 99%.”
Celestia, Avail, NearDA, and EigenDA are the astir important DA projects. They don't request to verify transactions, but simply cheque that each artifact was added by statement and that caller blocks are disposable to the network. They trust connected third-party sequencers to execute and verify transactions. Celestia was launched successful October 2023, Avail and EigenDA person their mainnet successful coming months, and Near has astir precocious announced its DA solution. Let’s reappraisal the unsocial features of each:
Celestia chose the fastest roadworthy to marketplace with fraud proofs (which are besides utilized by optimistic rollups). The tradeoff is that successful the existent configuration, Celestia won’t beryllium capable to enactment ZK rollups. Celestia’s squad claims that astir 70% of each caller Arbitrum Orbit chains are utilizing Celestia for information availability.
Avail (ex Polygon Avail) arsenic a standalone blockchain provides a accelerated and unafraid information and statement furniture that gives developers what they request to motorboat a rollup (whether a ZK oregon optimistic).
EigenDA is astir apt the astir Ethereum-aligned, due to the fact that it’s a DA module, not a blockchain. Also, the restaked ETH successful EigenLayer volition beryllium disposable to unafraid rollups utilizing EigenDA. Its weakness is that it’s not using information sampling oregon information availability proofs.
NearDA enables redeeming connected a rollups’ information availability fees, by storing information connected Near’s sharded blockchain. NearDA leverages an important portion of Near's statement mechanism, which parallelizes the web into aggregate shards.
And past we person the rollups themselves. Of the rollups that physique connected these DA providers, determination are a fig of tools to marque it easier to motorboat a rollup:
By harnessing Celestia's modular information availability, Manta Pacific provides importantly little costs compared to monolithic L2 solutions, and has already saved $1million successful Ethereum state fees. Manta besides uses customized opcodes for verifying ZK technology, which makes it truly inexpensive for them to person privateness and autochthonal randomness successful the protocol.
The Mantle Network is constructed upon a modular architecture that merges an optimistic rollup protocol with the information availability solution from EigenDA. This integration enables the Mantle Network to inherit Ethereum's information portion besides providing much affordable and readily accessible information availability.
Kinto is simply a KYC’d concatenation wherever each idiosyncratic and developer indispensable implicit a passport KYC process earlier transacting connected the network. It uses Celestia to thrust down costs.
In a genuinely modular way, modules of each furniture are chosen based connected circumstantial needs. The assortment of operation options tin beryllium seen here:
Rollup-as-a-service projects similar Eclipse marque it adjacent easier to motorboat a rollup, wherever the developer chooses which exertion to usage for each of the 3 modules.
Similarly, Conduit allows you to deploy a rollup successful 15 minutes, with Optimism, Arbitrum Orbit, and Celestia arsenic the supported stacks. A monthly hosting infrastructure interest is paid to Conduit, and there's a abstracted information availability interest paid to the provider.
The wealthiness of imaginable combinations that modularity creates is surely a large measurement forward. Is it akin to the trouble of gathering an aboriginal website compared to the easiness and customization of Squarespace today?
Despite the maturation successful DA projects, galore person reservations astir outsourcing DA. Vitalik made his clear: “Your information furniture indispensable beryllium your information layer.” Dankrad Feist, different subordinate of Ethereum Foundation, concurs: “If it doesn't usage Ethereum for information availability, it's not an (Ethereum rollup) and truthful not an Ethereum L2.”
We agree. Rollups with outsourced information availability volition beryllium little unafraid than those utilizing the aforesaid concatenation for information and statement (and truly should beryllium referenced arsenic “validiums”), though secure enough for definite applications. Short-term projects utilizing specified rollups volition look and slice quickly, making it a bully experimentation and investigating ground. However, for semipermanent holding of fiscal assets, L1s specified arsenic Ethereum oregon rollups utilizing them some for information and statement volition stay the networks with the lowest hazard profile.
While skeptical astir outsourced information availability, Ethereum is large connected modular architecture. The aboriginal imaginativeness of scaling via sharding was abandoned successful favour of modular.
The 3 main updates needed to instrumentality the imaginativeness are rollups (we talked astir these before), proposer-builder separation (“instead of a artifact proposer generating a ‘revenue-maximizing’ artifact by itself, it delegates the task to a marketplace of extracurricular actors (builders)”), and data sampling. The second is simply a mode for airy nodes to verify that a artifact was published by lone downloading a fewer randomly selected pieces of data. This is technically much challenging than the different 2 and volition necessitate two to 3 years to ship.
Important note: EIP-4844 was the archetypal measurement successful improving Ethereum’s information availability furniture earlier information sampling goes live. As discussed earlier, enhancing Ethereum is akin to gathering the level whilst flying; erstwhile the Ethereum Foundation recognized the request for rollups (aka erstwhile Vitalik dropped the celebrated rollup-centric future), the squad opted to widen blocks with blobs (a dedicated abstraction tailored specifically for rollup data). Blobs are expected to trim the outgo of rollup transactions up to 10 fold. EIP-4844 is scheduled to spell unrecorded with the Dencun upgrade successful March/April. While this is simply a impermanent solution to support Ethereum competitory for 2 to 3 years, the semipermanent solution volition beryllium supporting validity proofs connected mainnet itself, which volition marque rollups orders of magnitude cheaper.
While Solana mightiness beryllium powerfully defending its doctrine of monolithic architecture (and they mightiness beryllium close for galore usage cases), the manufacture seems to beryllium converging connected modularity. In the lawsuit of Ethereum, lone modular architecture volition alteration a aboriginal where:
1. Transactions are inexpensive for millions of users acknowledgment to rollups (scalability);
2. The web is protected from censorship and threats similar 51% attacks (security); and
3. An mean PC oregon adjacent a mobile tin tally a node to verify transactions (decentralization).
One mightiness inquire if Ethereum’s modular architecture solves the blockchain trilemma that was expected to beryllium unsolvable? Technically it doesn’t, due to the fact that Ethereum is not a monolithic web anymore, but arsenic a modular network, it does.
Of these three, we deliberation decentralization is the astir important portion of the trilemma to solve. Innovation volition yet thrust down transaction costs; prioritizing decentralization (especially geographic) is the lone mode to guarantee semipermanent information for the network. Ethereum is starring successful decentralization by having the astir distributed validator set, with much than 800,000 validators. At the aforesaid time, with the modular approach, it tin accommodate to caller plan innovations done customized rollups that motorboat connected top. Celestia and others surely stock this vision. The question remaining is whether Ethereum tin determination successful this modular absorption accelerated capable to support up with the competition, which is gathering from scratch, and not fixing the level whilst flying.
