This ledger is composed of blocks, and each block contains a batch of validated transactions.
The blocks are cryptographically linked together in a continuous chain, making the historical record immutable.
Data Size: The entire Bitcoin blockchain is a continuously growing dataset. As of mid-May 2025, it's approximately 660 GB. When you run a full Bitcoin node, you download and store this entire dataset.
Transaction Data: Each Bitcoin transaction is a piece of data that specifies:
Which bitcoins are being spent (transaction inputs).
Which new bitcoins are being created (transaction outputs, including the recipient's address and the amount).
Cryptographic signatures that prove the sender's ownership.
Other metadata like timestamps and transaction versions.
This data is structured in a very specific binary format, often represented in hexadecimal.
A block header: This fixed-size piece of sri lanka phone number list data includes a timestamp, a reference to the previous block's hash, a Merkle root (a hash of all transactions in the block), a difficulty target, and a nonce (the number miners adjust).
A list of transactions included in that block.
Network Data:
Peer information: Data about other Bitcoin nodes your client is connected to.
