Understand Bitcoind and its file system
As a Bitcoin user, Bitcoin software, including Bitcoind’s internal operation, is essential. In this article, we examine how to determine that bitcoind is synchronized with the network.
Basics of Bitcoind
When you install Bitcoind on the Ubuntu system, it creates a new library structure that reflects its configuration and data files. Here you can find an overview of the file system layout:
./Database: Store Bitcoin database, information on blocks, transactions and other relevant data.
./blokokok/index": Database of all Bitcoin network blocks with time stamps and transaction numbers.
- Other subdirectors: These contain different files for each block or transactions.
Sync with the network
To confirm Bitcoind is synchronized with the Bitcoin network, you can check the following files:
1.
* If the file size is about 16 kb (16,000 bytes) and not too large, then probably not synchronized.
2.
* The time block of the last block of the library must be close to the current time.
- Other subdirectors:
* If there are files such as0001.txt, a 0002.txtor similar, this indicates that they are not synchronized yet.
The "du -H" command
Theducommand is used to estimate the use of the library. When you rundu -h./Database, here's what you will see:
- The first line displays the size of each file in the directory, the unit (k
,m, etc.) and the number of libraries (/) on the left.
- The following few lines show the estimated full size of files and subdirectors.
For example:
16k ./database
59m ./blocks/index
29g ./blocks
646m …
`
In this case, the first line indicates that the /database library contains about 16 kb (1.6 MB) data.
Conclusion
To confirm Bitcoind is synchronized with the bitcoin network, examine the size of the/database” and the /block/index" directory. If they are not too large, the block synchronization process is likely to be in progress. As a general rule, however, these libraries should be about 1-10 MB after 10 hours, depending on the network conditions.
More tips
- You can check your current time by running "Date or using a device such as" Time ".
- If you are concerned that the synchronization process will take too long, consider increasing the disk space available to Bitcoind (-D `).
- Regularly check your file system for changes that can indicate synchronization problems.
