Explore the Ethereum Mainnet Blockchain Network

The Ethereum Mainnet network is a public blockchain that’s supported by all Ethereum clients including Geth, Parity, Nethermind, Hyperledger Besu and many more. The network supports a modified version of Nakamoto consensus via transaction-based state transitions.

Established in July 2015, Ethereum Mainnet is a proof-of-work network that has grown to become the single most active chain in the Ethereum ecosystem and almost all blockchain networks.

Discover our dedicated Block Explorer tool to search the Ethereum Mainnet network in the click of a button. Anyblock Analytics makes it fast and easy to search the Ethereum Mainnet using either transaction hashes, blockchain addresses, block numbers or log identifiers.

Stay in the loop and monitor on-chain events with up-to-date access to the latest Mainnet blocks and transactions. Using Block Explorer means accessing Ethereum Mainnet is as simple as clicking on a block or transaction to reveal a detailed summary of all the key information.

Anyblock Block Explorer Features

Our Block Explorer collates all internal transactions on Mainnet. We work with the network’s data to format the correct decimal place values for token transfers along with accurate token icons and metadata.

Anyblock Analytics translates all raw blockchain data into human-legible information that can be presented with a probability value between 0.1 and 1.0. A probability of 1.0 represents an exact match.

If you're searching the Mainnet explorer using smart contract addresses, the results page will show the source code and contract ABI if this information is available. You can easily filter through corresponding transactions and smart contract logs for fast and easy-to-use experiences.

Any address will show its balance in the native currency of the blockchain network.
