Judging from what Song said, Google is preparing a really simple in-use solution that will seamlessly integrate cryptocurrencies into the Google ecosystem used by billions of people across the world.
He said Bitcoin wallets will be embedded into the web2 interface so that users will be able to log into their BTC wallets using Google accounts. As for crypto payments, Google aims to make them as simple and intuitive as already existing web2 payment solutions.
Another focus of the Google team is ensuring the security of their solution. They strive “to address trust issues between on-chain and off-chain systems.” To maintain stable, trustless functioning, Google is going to deploy Zero-Knowledge Proofs or similar encryption technologies.
