Data availability blockchain Celestia is live on mainnet, making it the first modular data availability network to be publicly available. 

Celestia’s mainnet launch will consist of rollups that use the network as its data availability and consensus layer.

The team recently initiated its airdrop efforts, through which 6% of the tokens total circulating supply was set to be awarded to eligible participants.

Data availability refers to the capability network nodes have to download transaction information, store the information and ensure that participants can access the information to verify or dispute its accuracy. 

On layer-1 blockchains like Ethereum, network nodes download the data from each block, preventing invalid transactions from being executed. 

What Celestia offers is a data availability layer, which can verify transactions through data availability sampling (DAS) — without the need to download data from an entire block.

Using a data availability layer can increase the efficiency of a blockchain, drastically improving transaction speeds and minimizing costs.

In this initial launch, blocks will be between 2MB and 8MB in size and will be upgradeable based on on-chain governance. 8MB of blobspace is estimated to be around 9,000 to 30,000 ERC-20 transactions every second.

The Celestia team plans to increase block sizes to roughly 1GB as part of its roadmap.

“Celestia’s mainnet beta launch marks the arrival of the first live modular data availability network with data availability sampling (DAS) light nodes,” said Ekram Ahmed, spokesperson for the Celestia Foundation.

Celestia’s mainnet launch follows the unveiling of Nexus — a network of bridges that enables developers to bootstrap liquidity across various crypto ecosystems. 

Nexus was developed by contributors from Neutron, Hyperland and Mitosis using the Inter Blockchain Communication protocol (IBC) and a modular security stack designed by Hyperlane.

Research

MetaDAO has turned ownership coins from an experiment into a functioning capital formation platform, but its next challenge is distribution. If it can leverage Solana’s strong startup ecosystem and favorable US regulation to increase launch cadence and produce durable winners, MetaDAO could emerge as a leading venue for Internet Capital Markets and move early-stage fundraising toward open, liquid markets.
