Why Rollups Need Data Availability Layers: How EIP-4844 Enhances Ethereum's DA Capabilities
The Scalability Trilemma and Rollup-Centric Ethereum
For years, the blockchain community has grappled with the scalability trilemma—balancing decentralization, security, and throughput. Ethereum’s answer? A rollup-centric roadmap. But here’s the catch: most rollups rely heavily on Ethereum’s ability to function as a data availability (DA) layer. Enter EIP-4844, or Proto-Danksharding—a game-changer designed to turbocharge Ethereum’s DA capabilities.
Why Rollups Need Data Availability
Rollups promise execution integrity at lower costs by moving computation off-chain. But without DA, users can’t verify state transitions or withdraw funds independently. Optimistic rollups depend on fraud proofs, while ZK-rollups use cryptographic proofs. Both, however, require the underlying data to be available—not necessarily stored forever, but accessible long enough for verification.
The Cost of Calldata
Currently, rollups embed transaction data in Ethereum calldata, which is expensive (80% of rollup costs!). EIP-4844 introduces blob-carrying transactions, offering cheaper storage for DA-specific data. Blobs are temporary (~18 days), but that’s ample time for validity checks.
EIP-4844: A Technical Leap
- Blob Mechanics: Each blob holds ~125 KB of data, committed via KZG proofs. The EVM can’t access blob content directly—only commitments—reducing gas costs.
- Dual Fee Market: Blob gas prices are separate from execution gas, shielding rollups from L1 congestion.
- Future-Proofing: The design paves the way for Danksharding, where nodes sample blobs instead of downloading them entirely.
Challenges Ahead
While EIP-4844 boosts capacity (~100 TPS across rollups), it’s not a silver bullet. Full-scale Danksharding is still needed for true scalability. Until then, rollups must juggle blobs and calldata—or risk relying on external DA layers.

Les Blobs Débarquent !
Enfin, une solution pour que nos rollups arrêtent de saigner nos portefeuilles en frais de gaz ! EIP-4844 débarque avec ses petits blobs magiques – comme des croissants chauds pour la blockchain. 🥐✨
Pourquoi c’est génial ?
- Plus besoin de vendre un rein pour les données dispo (merci les KZG proofs !)
- Un marché du gaz séparé, comme une voie réservée aux Vélib’ mais pour les transactions.
Et le meilleur ? C’est juste l’apéro avant le Danksharding ! Alors, prêts à blobber ensemble ? 😏
When Your L2 Lunch Money Gets Stolen by Calldata
Watching rollups pay Ethereum’s exorbitant calldata fees is like seeing a Tesla charged by hamster wheels - technically possible but painfully inefficient! 🐹⚡
Enter the Blob Avengers
EIP-4844’s blob transactions are basically the Costco bulk purchase option for DA - 125KB of temporary storage that doesn’t bankrupt your favorite optimistic rollup. Temporary? Sure, but 18 days is longer than most crypto influencers’ attention spans!
Pro Tip: This upgrade finally lets us say ‘It’s not a bug, it’s a feature’ to Ethereum’s scalability issues with a straight face.
Thoughts? Should we start a GoFundMe for stranded calldata? 💸 #DankshardingWaitingRoom
Блоби – нові герої Ethereum
Ви коли-небудь бачили, як дані зникають через дорогі транзакції? EIP-4844 приносить нам «блоби» – тимчасові, але дешеві сховища даних. Це як доставка їжі, але для роллапів!
Чому це смішно?
Зараз роллапи платять 80% вартості за калдату. Блоби – це як знайти знижку 90% в Black Friday. Але не радійте занадто – вони живуть лише ~18 днів. Хоча для валідності цього достатньо!
Майбутнє за Danksharding?
EIP-4844 – це лише початок. Повноцінний Danksharding дозволить нодам «пробувати» блоби, а не завантажувати їх повністю. Уявіть собі дегустацію даних замість повного обіду!
Що думаєте? Чи готові ви до ери блобів? 😄
EIP-4844: O Herói que os Rollups Precisavam\n\nFinalmente, uma solução para os rollups que não envolve vender um rim para pagar gas fees! O EIP-4844 chegou como um salvador, trazendo os blobs – aqueles pacotes de dados temporários que são como os pasteis de nata: deliciosos, mas não duram para sempre (18 dias, para ser exato).\n\nGas Fees? Não, Obrigado\n\nCom os blobs, os rollups podem finalmente respirar aliviados. Afinal, quem precisa de calldata caro quando você pode ter armazenamento barato e eficiente? É como trocar um Ferrari por uma bicicleta elétrica: chega lá na mesma, mas sem esvaziar sua carteira.\n\nE você, já está pronto para embarcar nessa nova era da escalabilidade? Ou vai ficar preso no passado, pagando gas fees absurdas? Comentem abaixo!
¡Los rollups tienen hambre de datos! 🍽️
EIP-4844 llega como el ‘proto-Danksharding’ para darle de comer a esos rollups famélicos que dependen de la capa de disponibilidad de datos (DA) de Ethereum. ¡Adiós a los costosos calldata, hola a los blobs temporales! 🎈
¿18 días son suficientes? ⏳
Como un tupper de comida en la nevera, los blobs duran ~18 días. Suficiente para las verificaciones, pero… ¿y si te quedas sin tiempo como con esa ensalada olvidada?
Doble mercado de gas: ¿el truco definitivo? 💸
Separar el gas de los blobs del gas de ejecución es como tener dos carteras: una para las cryptos serias y otra para los NFTs frikis. ¡Estrategia financiera 101!
¿Será esto suficiente o seguiremos soñando con el Danksharding completo? 🤔 #CryptoHumor
Роллапы на диете
EIP-4844 пришел, чтобы спасти роллапы от голодной смерти! Теперь данные хранятся в «блобах» — как фастфуд для блокчейна: быстро, дешево и без лишних калорий (читай: gas fees).
Кто тут главный?
Когда роллапы зависят от доступности данных, это как кот, который требует еду ровно в 5 утра. EIP-4844 — это автоматическая кормушка для таких котов.
А вы как думаете? Готовы ли вы перевести свои транзакции на «блобное» питание? 😄
Ethereum Akhirnya Punya ‘Jalur Khusus’!
Dengan EIP-4844, Ethereum seperti punya jalur busway untuk data rollup - nggak perlu lagi tawar-menawar dengan biaya gas yang bikin kantong kering!
Blob itu Bukan di Wajah, Tapi di Blockchain
Fitur ‘blob’ baru ini kayak penyimpanan sementara yang pinter: cukup 18 hari buat verifikasi, terus bisa lenyap. Lebih hemat daripada calldata yang harganya selangit!
Masih Ada PR Siih…
Ini baru langkah awal menuju Danksharding. Tapi setidaknya sekarang rollups bisa bernapas lega - bayangin kayak dikasih stiker ‘priority pass’ di Bandara Soekarno-Hatta!
Gimana menurut kalian? Bakal bikin investasi crypto lebih asik nggak nih?
Турбо-зарядка для Ethereum
Звичайно, коли кажуть ‘масштабованість’, Ethereum відповідає: ‘Додайте блобів!’ EIP-4844 - це як встановити турбо на старий двигун. Тепер наші улюблені роллапи можуть дихати вільно (і дешевше).
Хто тут економить на газі?
Каллдата занадто дорога? Блоби - це як акція в супермаркеті для роллапів. Тиждень тому вони платили 80% за газ, тепер сміються до банку. Але пам’ятайте: це лише тимчасове зниження цін!
Як вам таке покращення? Пишіть у коментах, хто вже почав готуватись до Danksharding!
