Block chain simplified graph of data fields

Summary

[edit]
Description
English: Graphic of data fields in Bitcoin block chain. Simplified depiction: some fields are missing.
  • Prev_Hash: hash value of previous block. The purpose is to chain all blocks together.
  • Tx_root: root hash value of a hash tree (w:merkle tree) over all transactions.
  • Timestamp: creation time of block, as seen by block creator. The timestamp is checked by other clients and must be within a certain window (tolerates small clock skews).
  • Nonce: any number to make sure the resulting hash value of this block is below the target hash value. The Nonce is a 32 bit number and the 2^32 number space is exhausted during mining within less than a second.
The transactions (Tx0, Tx1, ...) are appended to the block. The first transaction generates new bitcoins and contains the coinbase field which includes an extraNonce to provide a larger search space for valid block hash values.

Metadata

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
