For the sake of argument, I have some knowledge of bitcoin and blockchain but that I didn’t use them due of my unstable financial situation. I'm about to begin investing and even trading. The name speaks for itself. What function does blockchain serve? Is it merely necessary for recording every transaction, making it essentially just a database? Please continue to be pertinent; I am aware of how blocks are produced.
Depending on design the functions of blockchain may be different.
Regarding to bitcoin, blockchain invests decentralized and distributed ledger (financial database) with immutability, security, transparency and trustlessness .
Nedless to say, being FOSS, it reqires neither permission no border to be used.
