What exactly does a blockchain validator do?

Validators verify transactions, enforce network rules, and secure the blockchain. In return, they earn rewards from newly created tokens and transaction fees. Think of them as both the infrastructure operator and a participant in the network's economic system.

Why would a company run a validator instead of just using the blockchain?

Running a validator gives companies visibility into network performance, influence over governance, direct access to rewards, and strategic positioning in multi-chain ecosystems. It's the difference between renting cloud services and owning your data center.

Is this a sign blockchain is actually going mainstream?

Not quite. It's a sign that major financial institutions see blockchain infrastructure as strategically valuable. But mainstream adoption for consumers is still years away—this is institutions securing positions of control first.
