All miners are nodes...Not all nodes are miners?
Discussion
yep
And Nodes don't get incentivised unless they're miners?just curious...
Isn't this a contradict to what Satoshi wrote on the Whitepaper...
as a node you can verify blockchain and verify your own wallets and operations. as a miner you can validate yours and others transactions among verify them. note the difference between validate and to verify. to valide needs proof of work and to verify i suppose not.
Im sorry i am again getting confused so how does a miner validates transactions?
The work done in mining a bitcoin means solving a puzzle for which there is no consistent formula. The way to find the right answer is a lot of trial and error. This is the design. There is no substitute for just running lots of numbers through the algorithm until you find one that works. And as time goes by, the number of possible combinations gets bigger, hence the more computing power is required to consistently produce solutions. Having found the answer, though, working back to check it is the right answer is very straightforward.
