Google has been working on a new tool to more efficiently search blockchains for specified data, which is helping shed light on the legitimacy of cryptocurrency transactions.
Blockchain ETL (extract, transform, load) is technology built on Google’s big-data analytics platform, BigQuery, and better enables users to search transaction data more efficiently. Allen Day, ETL’s developer, recognizes that if cryptocurrencies go mainstream then “it will require having some trust in knowing about who it is you’re actually interacting with” rather than only an consensus of anonymous trust. This will require advance searching
technology able to harness the large amount of data on the blockchain.
