** Ponimanion form

At work with Bitcoindb blocks files, it is important to reinstate the blockage Klavish format and their co -maintained. This is important for the effective section of the concrete blocks in the database.

What is the blocking Klavyshi?

Klavyshi blocks, also exasperations as the identifies of blocks or Nomer blocks, are unique with uniformers appointed by each blockchain block. They are the servants of the etiquette, which helps the Bitcoind to determine what the block is enhanced by the procedure and the block of the block.

PRIMER WARIANTS

In addition, you want to find the block in the database. You can jet the BLK field

`Bash

Blk00029.dat | 0x01 (Accessibility) | 0x08-0x07 (IDentifier block: 0x12345678)

Zamm you can use the BitcoindB Komand Strokindb (Bitcoind -DB Path/to/DB -query Blk00029.dat | Grep Block_id: 0x12345678)

Ponimic format containing the clown block and the use of the “BLK” field with the gastrointestinal baky, you can efficiently at the trolled blocs in the base of the leveling of level.
