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.
