The first modular data availability network, launched in October 2023, that separates data availability and consensus from execution. Celestia uses data availability sampling (DAS) and namespaced Merkle trees so light nodes can verify data availability without downloading full blocks. Over 56 rollups use Celestia for DA, with support from Arbitrum Orbit, OP Stack, and Polygon CDK.

The guarantee that a block's transaction data has been published and can be downloaded by any network participant. In modular blockchains and rollups, DA layers ensure off-chain execution data remains visible, complete, and verifiable. Data availability sampling (DAS) allows light nodes to probabilistically verify availability by checking random chunks without downloading entire blocks.
A blockchain architecture that separates core functions (execution, consensus, data availability, settlement) into specialized layers rather than handling all functions on a single monolithic chain. Modular designs allow each layer to be optimized independently, dramatically improving throughput and reducing costs. Celestia, EigenDA, and Avail serve as dedicated data availability layers, while rollups handle execution.
A Layer 2 scaling technique that executes transactions off-chain, bundles them, and posts compressed data back to L1. Optimistic rollups assume transactions are valid and use fraud proofs for disputes (7-day challenge period). ZK rollups generate cryptographic validity proofs for every batch. Rollups inherit L1 security while providing 10-100x throughput improvement.

A distributed, append-only ledger that records transactions in cryptographically linked blocks. Each block contains a hash of the previous block, forming an immutable chain. Nodes in the network maintain copies of the ledger and reach agreement through consensus mechanisms. Blockchains enable trustless, decentralized record-keeping without a central authority.
The protocol by which nodes in a distributed network agree on the current state of the ledger. Common mechanisms include Proof of Work (Bitcoin), Proof of Stake (Ethereum, Solana), and BFT variants. Consensus ensures all honest nodes converge on the same transaction history despite potential network delays or malicious actors.
A consensus mechanism where validators are selected to produce blocks based on the amount of cryptocurrency they have staked (locked) as collateral. PoS is energy-efficient compared to Proof of Work. Misbehaving validators risk losing their stake (slashing). Solana, Ethereum (post-Merge), Cosmos, and Cardano use PoS variants.
A consensus mechanism where miners compete to solve computationally expensive puzzles to produce blocks and earn rewards. PoW provides strong security (51% attack resistance) but is energy-intensive. Bitcoin and pre-Merge Ethereum use PoW. The difficulty adjusts to maintain target block times regardless of total network hash power.
