Power Your Avalanche C-Chain Apps with Real-Time and Historical Blockchain Data

Avalanche is an open-source platform for launching decentralized applications and enterprise blockchain deployments in one interoperable, highly scalable ecosystem. Avalanche is the first smart contracts platform that processes 4,500+ transactions/second and instantly confirms transactions. Ethereum developers can quickly build on Avalanche as Solidity works out-of-the-box. A key difference between Avalanche and other decentralized networks is the consensus protocol. Over time, people have come to a false understanding that blockchains have to be slow and not scalable. The Avalanche protocol employs a novel approach to consensus to achieve its strong safety guarantees, quick finality, and high-throughput, without compromising decentralization.
