the problem of who used to be, it doesn't need to be debated, because of the presence of bitcoin and blockchain to complement and need each other, bitcoin can't do much without the presence of blockchain, as well as blockchain, like body and life, they can't be separated ..
They go side by side. And there's no need to argue which comes first because they are invented on the same period. The other one will not exist without the other. And what is the significance when the other comes first? I don't think there's really point of arguing on this topic. Blockchain is the digital ledger of transactions so it is important for bitcoin itself. This will give you idea what are the early transactions made in btc network. Without blockchain, we won't know the history of bitcoin.
It can't be separated. Bitcoin and Blockchain or altcoins with Blockchain have an attachment and need each other. Blockchain becomes a ledger that will record every transaction made and the transaction is transparent and can be seen by anyone and cannot be deleted. Blockchain is like an Android system where applications run on that system. Bitcoin is arguably only one application of the blockchain system and there are many other applications ( Altcoins).
Let me answer together. Yes, we look at Bitcoin and blockchain from now on. They are combined and cannot be separated. They are perfect as a whole. What I want to emphasize here is the birth process of Bitcoin and blockchain. Before the birth of Bitcoin, there was no blockchain in human civilization. Neither the concept of a blockchain nor a complete blockchain technology product exists. When Satoshi Nakamoto created Bitcoin in 2009. Different scientific and technical personnel conduct in-depth research on the realization principle of Bitcoin. It slowly verified the feasibility and unbreakability of Bitcoin technology. Then, according to the realization principle of Bitcoin, this technical system was extracted step by step, and it was named the blockchain. I believe that some of the early participants of Bitcoin may understand the specific meaning I want to express. In 2013, no one mentioned blockchain at all. The concept of blockchain has been widely mentioned around 2015.
