What exactly does a blockchain validator do?

Validators confirm transactions, enforce protocol rules, and help secure decentralized networks. In return, they earn rewards (typically tokens and transaction fees). Think "accountant + gatekeeper combined."

Why would a company like Visa want to run a blockchain validator?

Revenue generation through staking rewards, governance influence, visibility into network operations, and strategic positioning in cross-chain infrastructure. It shifts validators from pure cost centers to potential profit centers—if the economics hold.

Is this a sign that blockchain is finally going mainstream?

It's a sign that institutions are getting serious about extracting value from blockchain infrastructure. Whether that counts as "mainstream adoption" depends on your definition. The technology didn't change. The power dynamics did.
