Perhaps more importantly, API endpoints also don’t exist for viewing the blockchain data in aggregate. While the Ethereum blockchain peer-to-peer software has an API for a subset of commonly used random-access functions (for example: checking transaction status, looking up wallet-transaction associations, and checking wallet balances, for example), API endpoints don’t exist for easy access to all of the data stored on-chain. All historical data are in the ethereum_blockchain dataset (documentation here), which updates daily. The Ethereum ETL project on GitHub contains all source code used to extract data from the Ethereum blockchain and load it into BigQuery-we welcome more contributors and more blockchains! Why make Ethereum blockchain data available on Google Cloud?

The Ethereum blockchain data are now available for exploration with BigQuery. An aggregate of coordinated smart contracts could be used to build a decentralized autonomous organization. This is in contrast to the Bitcoin value transfer mechanism, for which it can be difficult to determine the balance of a given wallet address.Īddresses can be not only be wallets that hold balances, but can also contain smart contract bytecode that allows the programmatic creation of agreements and automatic triggering of their execution. Tokens are created and managed by smart contracts.Įther value transfers are precise and direct, resembling accounting ledger debits and credits. However, the majority of value transfer on the Ethereum blockchain is composed of so-called tokens. The Ethereum blockchain’s primary crypto-economic unit of value is Ether, while the Bitcoin blockchain’s unit of value is Bitcoin. However, the Ethereum dataset is notably distinct from the Bitcoin dataset: Both are essentially OLTP databases, and provide little in the way of OLAP (analytics) functionality. With regards to the system architecture, Ethereum resembles Bitcoin in that it primarily serves to record immutable transactions. However, creator Vitalik Buterin extended its set of capabilities by including a virtual machine that can execute arbitrary code stored on the blockchain as smart contracts. Like its predecessor, Bitcoin, you might think of the Ethereum blockchain as an immutable distributed ledger. Today we’re making the Ethereum dataset available. Earlier this year, we made the Bitcoin dataset publicly available for analysis in Google BigQuery. Digital currencies are only one application of the underlying blockchain technology. Ethereum and other cryptocurrencies have captured the imagination of technologists, financiers, and economists.
