Our take
Keeping control over your identity online is becoming increasingly difficult. Spruce is setting out to combat this by leveraging the power of blockchain. The company's main target is allowing users to sign in online using their Ethereum account instead of a traditional intermediary. This offers increased privacy and ownership for users.
Spruce is one of a raft of new companies looking to leverage the power of blockchain to improve consumers' privacy and autonomy online, which means there is no shortage of competitors in the space. That said, its funding success, integration capabilities and backing have given it an important edge, and these factors stand strong as promises of its future potential.
