BitFly

BitFly, branded as bitfly, is a European Ethereum infrastructure and tooling developer that started with bitcoin and Ethereum mining pool operations before moving into staking and block exploration. Its products include Ethpool, a non-custodial Ethereum staking service, an open-source consensus layer explorer, a hosted explorer for the Gnosis chain, and mobile applications for monitoring validators.

Technically, that explorer indexes consensus layer data and presents validator status, block proposals, slashing events and epoch-level attestation and balance changes in structured form, exposing the same data through a public API that wallets, staking providers and research tools consume; a companion service publishes a reference rate for staking rewards. The company positions itself as a public data and service provider for the Ethereum ecosystem, serving validators, staking operators and ordinary token holders.
