Celestia

Celestia is the first modular data availability network, designed to handle one job: ensuring transaction data is published and accessible to anyone who needs to verify it. It is based on Mustafa Al-Bassam’s 2019 whitepaper, LazyLedger, which proposed a ledger that abstracts from computation entirely and acts purely as a data availability layer. Celestia does not execute or settle transactions. It simply orders data blobs and ensures they remain available.

The problem Celestia solves is one every growing blockchain eventually faces. Traditional blockchains like Ethereum bundle execution, consensus, and data availability into a single layer, so every node must process everything. Think of it as a single cashier handling checkout, inventory, and accounting simultaneously. Celestia’s modular architecture decouples execution from consensus. This allows developers to build independent rollups that rely on Celestia for secure, scalable data storage while managing their own transaction logic elsewhere.

The practical payoff for developers is significant. As of late 2025, over 56 live rollups leverage Celestia’s data availability layer. Production-grade platforms in gaming, AI-driven marketplaces, stablecoin protocols, and on-chain order books use Celestia to anchor their security and throughput. Rollup-as-a-service providers like Caldera and Conduit have built their stacks on it, and major Ethereum scaling frameworks have integrated it directly.

In December 2023, Polygon Labs announced the integration of Celestia with its Chain Development Kit, enabling Polygon developers to use Celestia as a plug-in data availability component. In February 2024, Celestia became the first external project to contribute to the Arbitrum Orbit protocol layer. Optimism Labs has also enabled rollups built using its stack to choose Celestia as their data availability layer.

Celestia was founded by Mustafa Al-Bassam, Ismail Khoffi, and John Adler, blockchain engineers focused on scalability and modular design. The project launched its first developer network in December 2021 and its public mainnet in October 2023 alongside its token launch.

In October 2022, the team secured $55 million in funding led by Bain Capital Crypto and Polychain Capital. By September 2024, the Celestia Foundation raised another $100 million, again led by Bain Capital Crypto, with participation from Syncracy Capital, Placeholder, 1kx, and Robot Ventures. This brought total funding to $155 million. Bain Capital Crypto’s repeated lead investment across two rounds signals strong conviction from one of the most rigorous institutional allocators in the space.

TIA is Celestia’s native token, launched in October 2023 at around $2. It serves three interconnected functions in the network. Developers and rollups pay fees in TIA to post data blobs to Celestia, making it the gas token for the data availability layer. Validators stake TIA to participate in block production and secure the network through Celestia’s proof-of-stake consensus. Token holders vote on protocol governance proposals, including upgrades to block sizes and network parameters. Every rollup that posts data to Celestia creates direct demand for TIA, tying token utility to actual network usage rather than speculation.

TIA trades on major centralized cryptocurrency exchanges for standard purchases. For large token amounts, locked tokens, or SAFT notes, Acquire.Fi’s OTC and Secondaries Marketplace is the right venue.

You can buy Celestia tokens OTC on Acquire.Fi by engaging with existing sell listings in the marketplace, or you can submit a new Buy listing with your preferred valuation and token amount.

You can also sell Celestia tokens OTC if you hold a position and want to exit. Browse existing Buy listings to find a match, or submit a new Sell listing with your asking price and the amount you want to move.

From there, Acquire.Fi runs the process. The team handles background checks, NDAs, and counterparty introductions. You take ownership of due diligence and payment settlement, and Acquire.Fi supports both sides to help get the deal done.
