Here's a fun fact, it was tackled before that cryptocurrency, specifically bitcoin has enough nodes that could possibly handle even a nuclear bomb attack. With that regards, with only one single node that runs bitcoin blockchain, could possible enable bitcoin to run which further makes it more secured than other store of value or investment platform.
From this, it is clear that blockchain is stored and shared by different nodes across the globe which enables us to to have our account and transactions possible.
Every computers. That can be from users, miners and such. It's mostly known as nodes. And to make things easier to understand, each nodes has a copy of transactions, and every new transactions are going to be added on it.
All the blockchain transactions are stored on a Full Node which it is usually a device like computer. The history of all transactions are recorded on a computer and all the incoming trasactions are added by means of nodes.
Blockchain was stored in your device or in short, the nodes. This nodes have a self copy of your transsction while the system have a list of data and that list is mostly updating if new information was entered.
In the most simplest words, blockchain is a 'chain' of records, like a ledger. This is stored in every node (computer) in the network. The network aforementioned, is the interconnected network of computers that operate the blockchain (validating transactions, adding blocks to the blockchain) while adhering to the network's rules.
Thus, the blockchain (records) exists in every computer that participates in it, since all of them has a copy of the ledger. You can use popular online blockchain explorers to find certain addresses, transactions, or blocks (since it is transparent for all, yet anonymous).
Blockchains are stored in PC's also known as nodes, within the system. The blockchain system is just like excel spreadsheet where every node have a copy of transaction done that updated frequently by users.
Blcokchain is stored in every computer also known as nodes. Each has their own copy and each transaction is updated to every node acting as a ledger to keep track of all the records or transaction that is done. Each information is shared by every node automatically.
Well, I just know a bit about it so I searched over the Internet and based on some articles the blockchain or cryptocurrency are stored in a nodes of every computer, and I just can't realized how it is possible to happen but because of its decentralized system even the transaction was pretty fast.
As what I have read Blockchain was stored in everyone's computer and the people who handled them can be called as nodes. Commonly these people are miners and people who used it.Blockchain is known to be decentralized thus, it cannot be stored in a single place coz this will classify as centralized.
