In October 2022, Celestia raised significant funding, led by Bain Capital Crypto and Polychain Capital, in a combined Series A and B round. This funding raised $55 million for the project, valuing it at $1 billion. Other notable investors included Coinbase Ventures, Delphi Digital, Placeholder, Jump Crypto, and Galaxy​.

A notable airdrop targeted various contributors within the blockchain community, including early adopters of the Cosmos ecosystem, stakers, relayers, Github contributors, and users of major Ethereum rollups. A total of 60 million tokens were earmarked for distribution among these groups.

The eligibility for the airdrop was determined by a snapshot taken on January 1, 2023. Addresses with an Ethereum value of less than $50 at that time were excluded. The distribution was divided among 576,653 addresses and 7,579 developers. Eligible Cosmos stakers and rollup users were set to receive between 50 and 110 TIA tokens, while developers were allocated between 1200 and 5000 TIA tokens. This airdrop represented a significant step for Celestia in establishing its presence in the blockchain world and rewarding those who have contributed to the ecosystem’s growth​​​​​​.

The overarching goal of Celestia is to revolutionize the blockchain space by providing a robust foundation for decentralized applications. This foundation is instrumental in fostering the next wave of blockchain evolution. The mainnet beta of Celestia, marking the start of a new “modular” era in blockchain technology, enables rollups and other modular chains to use the network as a data availability and consensus layer, further enhancing its utility and potential impact in the blockchain ecosystem.

How Does Celestia Work? Modularity and Data Availability Sampling

Understanding the workings of Celestia begins with grasping the concept of modular blockchains. Traditional, or monolithic blockchains, integrate four essential functions—execution, settlement, consensus, and data availability (DA)—within a single base consensus layer. This design means that all nodes in a network follow the same transaction sequence, from an initial state to a common final state, ensuring uniformity across the blockchain. However, this approach can limit system throughput, as the consensus layer juggles multiple tasks and cannot be optimized for a specific function.

In contrast, modular blockchains, like Celestia, decouple these functions across multiple specialized layers, allowing each layer to be optimized for its specific role. This separation typically divides the four functions into three layers: a base layer handling DA and consensus, and separate layers for settlement and execution. This structure enhances system throughput and allows for the use of multiple execution layers, such as rollups, on the same settlement and DA layers.

Rollups play a crucial role in Celestia’s architecture. They are a technique that enables decentralized applications to execute transactions outside the main blockchain. Transactions are grouped, validated by a set of validators, and the results are then recorded on the main chain as a single transaction. This method not only increases transaction efficiency and reduces costs but also ensures the network’s verifiability and transparency.

Celestia’s node structure reflects its modular design. It features different types of nodes, each with specific roles. Validator nodes participate in consensus by producing and voting on blocks. Full consensus nodes sync blockchain history. Bridge nodes link the Data Availability network with the Consensus network, while full storage nodes store all data without connecting to Consensus. Light nodes conduct data availability sampling. Lastly, Blobstream, a special L2 node, facilitates Ethereum application developers’ access to Celestia’s functionalities.

In summary, Celestia’s modularity and innovative use of rollups, combined with a diverse array of nodes, make it a highly scalable and efficient blockchain network, tailored for the evolving demands of the blockchain ecosystem.

Data Availability Sampling

Celestia’s Data Availability Sampling (DAS) is a key feature that enhances blockchain scalability and security. At its core, DAS allows light nodes to verify the availability of block data without needing to download the entire block, a crucial aspect given the permissionless nature of blockchain networks. This is achieved through two innovative technologies: 2-dimensional Reed-Solomon encoding and Namespaced Merkle trees (NMTs).

In DAS, block data is split into chunks, arranged in a matrix, and extended with parity data using Reed-Solomon encoding. Light nodes then randomly sample small portions of this data, verifying availability by checking the data chunks and corresponding Merkle proofs. This random sampling and validation process increases the likelihood that the entire block’s data is available.

This mechanism ensures that even with limited resources, light nodes can efficiently participate in the network, maintaining its integrity and functionality. The scalability of DAS lies in its ability to support larger blocks without overwhelming light nodes, as they only need to download a fraction of the data. By enabling light nodes to efficiently confirm data availability, Celestia significantly improves the scalability and reliability of its blockchain network.
