Blockchain is decentralized and, therefore, there is no central place to store it. That's why it's stored on computers or systems across the network. These systems or computers are known as nodes. Each of the nodes has a copy of the blockchain or, in other words, the transactions that take place on the network.
These people often earn a little money, which is paid in physical cash. They must then store this physical money in hidden places in their homes or other places of life, leaving them subject to theft or unnecessary violence. The keys to a bitcoin wallet can be stored on a piece of paper, a cheap mobile phone, or even memorized if necessary. For most people, these options are likely to hide more easily than a small pile of money under a mattress.
How are data (immutable blocks) stored in the general ledger of all the complete nodes of a Blockchain? is in memory, in a file (such as a JSON, CSV file) or in DB Blockchain is a distributed database. This means that the data is scattered across the nodes (participating computers). Each node can decide how to store the data (and if it will store it). When data is accessed, messages are sent to network nodes.
In principle, you don't have to store any part of the blockchain on your computer if you just want to send transactions. Blockchain protocol ensures that it can reconstruct data from bits of information received correctly and reliably. So, where are the user's Bitcoins actually stored? They are stored in the approved Blocks part of the only Blockchain version, the copy of which exists on every computer running a node worldwide.

A special program, a “wallet”, is needed to access and use the coins. The wallet protects the secret code you need to use your bitcoins and helps manage transactions. If you want to know how to store bitcoins, here's the main thing you need to know: Bitcoins are stored on the Bitcoin blockchain network. A special program, called a “wallet”, is required to access and use the coins.
Blockchain is based on distributed ledger technology (DLT). The DLT acts as a decentralized database of information on multi-party transactions. Trades fill the DLT in chronological order and are stored in the general ledger as a series of blocks. An interconnected chain is formed between blocks and each of them refers to the previous block, thus creating a blockchain.
Bitcoin's blockchain is also decentralized, meaning it's not stored on a master computer or controlled by a company. It is distributed across many computers that are on the network. If most network users agree that the new version of the code with the upgrade is solid and worthwhile, then Bitcoin can be upgraded. Such a record could be a list of transactions (such as with a cryptocurrency), but it is also possible for a blockchain to contain a variety of additional information, such as legal contracts, state IDs, or a company's product inventory.
Transactions that are part of the blockchain have to be approved by thousands of computers. After adding a block to the end of the blockchain, it is extremely difficult to go back and alter the contents of the block, unless the majority of the network has reached a consensus to do so. Let's say a hacker, who also runs a node on a blockchain network, wants to disrupt a blockchain and steal cryptocurrencies from everyone else. If you just bought a lot of bitcoins for long-term storage, then cold storage is the right way to store them.
A database structures data into tables, while a blockchain gathers information into groups, known as blocks, that contain sets of data. Blockchain works very differently than a traditional bank, as it is 100% decentralized and relies on thousands of computers to verify its transactions. Addresses don't actually have a balance (nor does the Bitcoin blockchain understand that addresses exist), but referring to an address balance is simply a quick way to refer to the total sum of tokens stored in unspent outputs that the owner of a particular address has the ability to spend. A blockchain is a digital ledger of duplicate transactions distributed across the blockchain's network of computer systems.
Information regarding the person or entity is passed from their Bitcoin wallet to their location and IP address, which represents Bitcoin's peer-to-peer interaction. Blockchain has the potential to eliminate the need to scan documents and track physical files at a local recording office. This system means that each blockchain is a database that is more complex, since it creates an irreversible data chain when implemented in a decentralized system. .
