It's time to stop calling Bitcoin "new technology". It's 13 years old. And blockchain hype started in 2015, so it has been 7 years since that.
As long has many haven't still seen the use of the technology and as long as it still remains a mystery to many it is a new technology until it becomes a toy that can be accessible and appreciated by all then we can discard the old name. Many around the world still don't understand what satoshi's innovation has brought about some still see it as a sort of ponzi.
Except blockchain doesn't really work outside of Bitcoin. The point of mining is to synchronize a large and open network of nodes. If it's a small private network, you don't need that. So blockchain minus mining is just a data structure that is append only, which is rather primitive and not desirable in many cases, because it's redundant and doesn't allow changing the data.
Minus mining Bitcoin is a file that works as a read and append only file and this is where mining comes in to prove the authenticity of the file been appended by a proof of work alogrithm on the Blockchain network. Ensuring it's validite through a digital voting system achieved through consensus
