Celestia (TIA) is pioneering a new era in blockchain architecture through its innovative modular design. As one of the first dedicated data availability (DA) protocols, Celestia reimagines how blockchains operate by decoupling the consensus and data availability layers from execution and settlement. This separation enables developers to build customized, scalable blockchains without reinventing core infrastructure—ushering in a new wave of innovation across Web3.
In this in-depth exploration, we’ll unpack the technical foundations of Celestia, compare it with key competitors like EigenDA and Avail, analyze its tokenomics, and examine recent upgrades shaping its future trajectory.
Understanding Celestia: The Modular Blockchain Revolution
Celestia is a modular data availability protocol designed to serve as the foundational layer for what’s known as modular blockchains. Unlike traditional monolithic chains such as Ethereum or Solana—where consensus, data availability, settlement, and execution are bundled together—Celestia focuses exclusively on consensus and data availability.
This minimalist approach allows other blockchains, particularly rollups and app-specific chains, to outsource their data publishing needs to Celestia while maintaining control over their own execution logic. It’s a paradigm shift: instead of forcing every node to process every transaction, Celestia ensures data is available and verifiable using lightweight mechanisms.

Why Modularity Matters
The rise of modular blockchains addresses critical limitations in scalability, security, and developer flexibility. By specializing each layer of the blockchain stack, networks can scale horizontally—supporting thousands of independent rollups without compromising decentralization.
Celestia was among the first to bring this concept to life when it launched its mainnet in 2023. Its early entry gave it a first-mover advantage, attracting projects like Eclipse, Manta Network, Aevo, Lyra, and Karak—all now publishing data on Celestia.
As of today, over 73 GB of rollup data has been posted to the network, with more than 20 active rollups leveraging its infrastructure.
Core Technical Innovations Behind Celestia
Celestia’s architecture relies on several cutting-edge cryptographic and networking techniques that enable secure, efficient, and decentralized data availability.
Two-Dimensional Reed-Solomon Erasure Coding
To prevent malicious actors from hiding parts of a block, Celestia implements erasure coding. This technique expands a block’s data by duplicating and encoding it into a larger structure. If an attacker wants to hide invalid transactions, they must withhold more than 50% of the encoded data—making attacks easily detectable.
This also enables Data Availability Sampling (DAS), where light nodes only need to sample small portions of a block to verify full availability with high statistical confidence.
Namespaced Merkle Trees (NMT)
Celestia organizes data using Namespaced Merkle Trees, which group data into isolated namespaces tied to specific rollups. This ensures that nodes only download data relevant to their chain, improving efficiency and reducing bandwidth usage.
NMTs also allow for compact proofs during verification, making data availability checks faster and more scalable.
Data Availability Sampling (DAS)
DAS is a game-changer for decentralization. Instead of requiring full nodes to download entire blocks—a resource-intensive task—light nodes can verify data availability by sampling random chunks of erasure-coded data.
This dramatically lowers hardware requirements, enabling broader participation and enhancing network resilience.
Light Node Clients
Celestia’s light clients are designed for accessibility. They don’t require expensive hardware or trust assumptions about honest majorities. Even if most validators are compromised, light nodes can still detect withheld data through DAS and fraud proofs.
This makes Celestia ideal for cross-chain applications where minimizing trust in source chains is crucial.
Fraud Proofs
Celestia uses optimistic fraud proofs: blocks are assumed valid unless challenged. If a full node detects invalid encoding or missing data, it can submit a cryptographic proof to alert the network.
While this introduces a challenge period before finality, it reduces computational overhead compared to zero-knowledge alternatives.
Competitive Landscape: Celestia vs. EigenDA, Avail & Ethereum Blobs
Despite being a trailblazer, Celestia faces growing competition from emerging DA solutions.
Celestia vs. EigenDA (EigenLayer)
EigenDA is a data availability service built atop Eigenlayer, leveraging Ethereum’s restaking ecosystem for security. Unlike Celestia, it's not a standalone blockchain but an Actively Validated Service (AVS) secured by restaked ETH and LSTs.
Key differences:
- Consensus Model: EigenDA uses Ethereum + Eigenlayer for consensus; Celestia runs its own PoS chain.
- Verification Mechanism: EigenDA employs KZG commitments (a form of zero-knowledge proof), enabling immediate validity verification—shorter finality than fraud proofs.
- Proof of Custody: EigenDA includes this feature to ensure operators actually store data.
- Dual Quorum Security: Requires both ETH restakers and native token stakers to attest, increasing fault tolerance.
- Censorship Resistance: Rollup nodes can directly interact with EigenDA operators, avoiding centralization around proposers.

Celestia vs. Avail Network
Avail, formerly part of Polygon Labs, launched independently in 2023 using the Polkadot SDK (Substrate). It uses Nominated Proof-of-Stake (NPoS) with BABE/GRANDPA consensus.
Notable distinctions:
- Like EigenDA, Avail uses KZG commitments for instant verification.
- Implements application-specific ordering via unique appIDs.
- Features Avail Nexus, a ZK coordination rollup that aggregates proofs and manages sequencer selection.
- Introduces Avail Fusion, allowing users to stake assets like BTC, ETH, or rollup tokens for consensus—unlike Celestia’s TIA-only model.
Celestia vs. Ethereum Blobs (EIP-4844)
With Proto-Danksharding (EIP-4844), Ethereum introduced blobs—temporary storage units holding up to 128 KB—for cheaper L2 data posting.
However:
- Blob space is limited and costly compared to Celestia.
- Users pay per blob regardless of utilization.
- Final implementation (Danksharding) remains years away.
Despite Ethereum’s dominance, Celestia has captured 44% of recent DA market share, according to Blockworks Research—driven largely by lower costs and higher throughput.
TIA Tokenomics: Powering the Network
The TIA token serves as the native utility and governance asset of the Celestia network. It secures the chain via Proof-of-Stake, pays transaction fees, and enables participation in on-chain governance.

The Lemongrass Upgrade: Strengthening Consensus
On August 8, 2024, Celestia executed the Lemongrass hardfork—its first major consensus-layer upgrade since mainnet launch. Known as CIP-17, it bundles five critical improvements:
- CIP-6 – Minimum Gas Price Enforcement: Enforces a floor gas price (0.000001 utia) to prevent off-chain fee agreements and ensure fair validator rewards.
- CIP-9 – Packet Forward Middleware: Enhances IBC functionality with multi-hop transfers and automatic fund recovery after timeouts.
- CIP-10 – Coordinated Network Upgrades: Raises upgrade threshold from ⅔ to ⅚ validator approval, reducing halt risks.
- CIP-14 – ICS-27 Interchain Accounts: Enables permissionless cross-chain account management—critical for DeFi and liquid staking.
- CIP-20 – Disable Blobstream Module: Removes deprecated Blobstream in favor of Blobstream X, powered by ZK circuits for Ethereum interoperability.
These upgrades reinforce Celestia’s robustness, interoperability, and long-term viability.
Future Outlook: Scaling Toward 1 GB Blocks
The modular blockchain ecosystem is still in its infancy—but rapidly evolving. Celestia and rivals like EigenDA have publicly targeted 1 GB per block capacity, which would exponentially increase scalability for rollups.
As data costs drop further:
- Launching custom blockchains becomes accessible to startups and indie developers.
- On-chain games and data-heavy dApps become feasible.
- A Web2-like model may emerge: developers pay for data hosting, not users—mirroring AWS-style infrastructure economics.
Celestia’s role as a pioneer remains pivotal. From concept in 2019 to mainnet leader in 2025, it continues driving innovation across the modular stack.
