🚀 Breaking news: All Chains Fit on EigenDA! ------------ EigenDA mainnet is now processing 15+ MB/second (120Mbps), and we are posting ALL raw block data from 15+ chains simultaneously. ------------ L1s: Bitcoin, Ethereum, Solana, Celo, Celestia, Avalanche, BNB chain, Fantom. L2s: Polygon, Mantle, Base, Arbitrum, Optimism, XAI games, Blast,... Scroll, ZKSync, Mode, Taiko. ------------ The *only* fully horizontally scalable system in crypto. ------------ All Ideas Fit on EigenDA. You can even inscribe your idea into EigenDA! ------------ What breakthrough are you going to build on ?show more

We are building EigenDA to the premium out-of-protocol DA layer on Ethereum, and it offers the following unique features: ------------ High Throughput: EigenDA is the ONLY fully horizontally scalable system in all of crypto. What does horizontal scaling mean? More nodes directly imply more throughput. In all other systems, decentralization is a roadblock to scaling. In EigenDA, decentralization IS scaling. Right now EigenDA has 15 MB/s throughput, order of magnitude more than other DA. ------------ Strong Trust Model: EigenDA uses dual staking of ETH and EIGEN, where EIGEN stakers can be forked for data availability - this is a breakthrough feature for an ERC20. This trust model is similar to any other data availability chain where if data is unavailable stakers can be forked via chain forking. Furthermore, EigenDA is built on KZG commitments rather than fraud proofs, making it possible to instantly verify correctness of coding. ------------ Low node requirements: The minimum node requirement for participation as EigenDA validator is 0.5MB/s. If you have more stake delegated to your node, you need linearly more node bandwidth. Other systems require 100+MB/s. ------------ Custom quorum: EigenDA allows rollups to easily add their own token quorum so that DA commitments are validated by both the default EigenDA quorum and any custom quorum. This feature is not available anywhere else. ------------ Reserved bandwidth: Rollups on EigenDA can have a reserved chunk of throughput which there will be no conflict with. Bored Apes does their drop and your app gets congested - **no more**. This feature is not available in any other crypto system. ------------

Roadmap ------------ In building a complex product like EigenDA, we cannot build all features simultaneously so we have prioritized unprecedented throughput and horizontal scaling to be the first core feature to ship. The architecture of EigenDA is designed to be forward compatible with a rich roadmap incorporating many breakthrough features. ------------ DAS for verifiability: EigenDA uses KZG polynomial coding and is therefore fully compatible with data availability sampling (similar to Danksharding). DAS is on the roadmap next to promote verifiability. We note that, DAS can be built permissionlessly by anyone (=anyone can build a light node). We instead prioritized scaling to build the world’s first fully horizontally scaled system - this cannot be done permissionlessly. DAS is coming up on the roadmap. ------------ Economics: EigenDA currently has a free tier with bandwidth cap and whitelisted higher tiers. We are introducing the full EigenDA economics in the upcoming release including pay-per-blob and reserved bandwidth - so that everything is fully permissionless. ------------ Permissionless Disperser: EigenDA currently has a single permissioned disperser to send the data to the EigenDA nodes (which is a liveness bottleneck not a safety bottleneck). This is necessary because rate limits right now without payments. Once permissionless payments goes live, the next step is to make the disperser permissionless. Once permissionless disperser goes live, any rollup sequencer can run its own disperser. ------------ Improved trust models. Right now, the trust model only allows economic security for EigenDA. We are not satisfied with this model - we need systems that are secure as long as Ethereum is secure. We have some research breakthroughs in this direction coming up.

With all of these features, eigenlayer is designed to usher in a new wave of open innovation in crypto. ------------- Convert cloud to crypto! ------------- Anything you can dream, you can build! What breakthrough are you going to build? -------------

@eigen_da putting all of celestia inside of eigenda is hilarious ngl

@eigen_da Smashed it

@eigen_da and also on Linea!✨☺️

@eigen_da Congrats to the team🎉 bringing horizontal scaling to crypto is a game changer Reserved bandwidth will also be huge for fee market stability

This is incredible! Few questions: 1. Could you please elaborate on how DAS would work when each node only holds a chunk of the data? Do light clients sample chunks from multiple nodes? 2. One thing I couldn't find in the docs is the Data lifetime - how long are the nodes required to store the data? Is that something rollups can pre-define? 3. What bottleneck caps the throughput at 15 MB/s currently?

@eigen_da This is sick. Great work!
