Covalent

Code Summery

The main purpose of the Covalent application is to provide a decentralized data infrastructure that ensures long-term data availability and verifiability for blockchain networks, particularly Ethereum. It achieves this by capturing and indexing blockchain data, which is then stored across multiple points in the network, allowing instant access through the GoldRush API. The Covalent Network also addresses the challenges posed by Ethereum' evolving architecture, such as rollups and state expiry, by taking on the responsibility of maintaining historical data accessibility. Additionally, it employs cryptographic proofs to ensure data verifiability, making it one of the first middleware protocols to implement a proof-based system for accurate data representation. The innovative Block Specimens format further enhances the network' capabilities by decoupling data storage from blockchain nodes, promoting composability and enabling users to easily manipulate and utilize blockchain data.
