Google is among the top five largest companies by stock market capitalization. It is quietly working with blockchain, particularly in the area of analytics and node operation.

Data analytics: Google Cloud collects data on Bitcoin and many other blockchains and provides that data to analysts via BigQuery. It also runs nodes for various blockchains including EOS and Theta.

Enterprise blockchain: Google Cloud offers blockchain-as-a-service, allowing developers to quickly deploy private chains and test environments,

Retail services: Google does not support Bitcoin or other cryptocurrencies as a means of payment in its Google Pay app.

Anti-crypto activities: Google has banned certain ICO-related advertising. Its subsidiary, YouTube, has also drawn criticism for blocking crypto channels that provide investment advice.

Investments: Google has not invested in Bitcoin or related financial products. However, Google Ventures has invested in at least one blockchain firm: Blockchain.com, as one member of a $120 million funding round.

Executive sentiment: Google Cloud developer advocate Allen Day is highly involved in Bitcoin and blockchain; he has taken an interest in numerous projects and discussed them at length in recent interviews.

Google co-founder Sergey Brin has stated that he "he [doesn't] know too much about cryptocurrencies." However, he has also stated the he and his son are involved in small-scale Ethereum mining. Google CEO Sundar Pichai has also mentioned Ethereum mining in a similar story.

Summary: Google is mainly interested in blockchain analytics rather than enterprise or retail services, but it is conceivable that the company will eventually add support for crypto payments.
