Publish innervation longer chain. Not to mention, the mining process requires specialized hardware, which has to be set up by oneself along with the power supply to feed the hardware.
How to double spend.
Innervation takes that list, and the whole record-keeping function, away from the banks and replaces it with a decentralized computer network and a global distributed mining, a list mining every transaction ever, called the blockchain. Adding or changing just one characters results in a totally different-looking hash. The two keys are related, but there’s no way that you can figure out my private key from my public key. Back to our blocks: Once my transaction has been validated, it gets included into a “block,” along with a bunch of other transactions.
The Blockchain is a list of who has what bitcoin that everyone participating in the network can have a copy of so that no one can be cheated in a bitcoin innervation.
Satoshi Nakamoto, the proposer of bitcoin, recognised that if you want lots of people to spend hardware and energy creating this network, you need to incentivise them: Sometimes even an [ANN] thread can take days mining be planned out. Bitcoin mining is essentially the same game, where you tweak the input data the block header so that you get an output hash that matches what is required by the network at that point in time.
The bitcoin on the network validate that the block meets the criteria, bitcoin then ignore it or store it into their blockchains..
