understanding the Bitcoin Bitcoin version header
The structure of the Bitcoin block has been the subject of a much curiosity and confusion between developers, traders and enthusiasts. An aspect of this structure that can be inconsistent is the number of changes that change, which seems to be randomly updated to each operating operation. In this article, we will deepen the details behind the Bitcoin Block title versions and explore which values can regulate the miners.
Block mounting structure
A Bitcoin block consists of several components including:
- `
version: the first field, which represents the number of version of the block installation.
2
3
count transactions **: total number of transactions included in the block.
Bite version numbers
The first two fields, the "version" is the factor for regulating inflation (AF), have fixed values:
- Version
: 0x00000001 (always 1)
Factory factor in factory (AF): never changes (is a constant)
However, the third field, Merkle root, has two possible versions:0x00000000 0xffffffffffffffffffffff. Block blocking can be divided into two parts:
- section block : contains only the first 32 bytes of the interstation.
- Data block : Contains all data stored in block (transactions, Merkle root, etc.).
The numbers of the miner’s adjusted bite versions
When the miners update their blocks at blocks at each extraction operation, they can adjust two values:
- Bit version ‘: This value is not influenced by the miner’s adjustments and remains 1.
2
The third field, “Merkle Root”, has a random version number that the miners can handle:
0x00000000
0XFFFFFFFFFFFFFFFFFFF
Miners can choose to update or both values with new data. However, there are some warnings:
- Inflation regulation value (AF) remains the same for the entire duration of the block.
- TheRoot version number Merkle` must be a valid Merkle root for the block transactions.
Why the numbers of the random version?
The use of random versions for “Merkle root” is the version is probably for historical reasons:
- In the previous versions of Bitcoin (pre-2012), the miners could update their block blocks only with the previous block data. With more efficient extraction algorithms, it has become possible to extract new blocks without using previous control points.
- Random version numbers are used to prevent the miners from exploiting the weaknesses in the system by handling the value of the inflation adjustment factor (AF).
Conclusion
In conclusion, the structure of the Bitcoin locking structure has the first two fixed fields, but it can have variable versions of three other fields: “Root Merkle” is the version. The miners can regulate the values ”the factor of inflation regulation (AF) is Merkle root”, but not of fixed values. Understanding these changes is crucial to developers, traders and fans who are based on exact information about blocking the block.
I hope this article has contributed to clarifying the mysteries around the Bitcoin block header!
