Doesn’t Bitcoin Transaction Verification Require Mining?

My understanding of the block structure that verifies Bitcoin transactions is that it is verified by the mining infrastructure, which essentially signs transaction blocks, including transactions. If the rate of mining decreases to the point where it is highly unprofitable, then who will be generating bitcoin blocks in the future?

Most likely we will see blocks increasingly generated by commercial high-speed transaction processing services, and not as much by miners.
