Bitcoin: How is the progress field of Bitcoin Core’s synchronisation/Initial Block Download debug logs calculated?

Debug protocols from Bitcoin Core’s Synchronization Progress Field Field

Bitcoin Core is software for managing Bitcoin letters and transactions. One of his most important functions is synchronization with other Bitcoin nodes to ensure that the blockchain data is up to date. This process includes downloading new blocks from other knots in the network, which can be a challenge due to the complexity of the blockchain.

Calculate the calculation of the ProgeGeD field in the DEBUG protocols

The debug protocols used by Bitcoin Core during the IBD (initial block download) generally contain information about the synchronization process. Here are some key elements that make up this progress:

Bitcoin: How is the progress field of Bitcoin Core's synchronisation/Initial Block Download debug logs calculated?

۱. Best hash

  • The “Best” field in the “Debug.log” file refers to a hash of the best block that has so far been found in the network.

  • It is calculated based on the latest available data that contains the block number, the hash and the previous best block -hash.

`Bash

UPDATIP: New Best = ...

۲. New Best Hash

  • The field New_Best indicates that a new best block was found.

  • This field is also calculated based on the latest available data.

۳. Block number and hash

  • The fields of block_number andhash contain information about the downloaded block.

  • These values ​​are used to calculate the best_hash.

`Bash

۴. Previous Best Block -Hash

  • The field poth_best_hash indicates which previous block was the best and how far back.

additional factors

In addition to these fields, other factors can be taken into account when calculating the progress of the synchronization of the Bitcoin core during the IBD. Some of them are:

۱. Block the block difficulty

  • The “Block_Difficulty” field contains information about the current level of difficulty of the block.

  • This can influence whether new blocks are downloaded and how quickly they are integrated into the blockchain.

`Bash

۲. Block difficulty ratio

  • The “Block_Difficulty_Ratio” field contains information on the ratio of the difficulty of a block of network difficulty.

  • This can influence whether blocks are downloaded and how quickly they are installed in the blockchain.

`Bash

۳. Block reward

  • The “Block_Reward” field contains information about the current reward for the mining of a block.

  • This can influence whether blocks are downloaded and how quickly they are installed in the blockchain.

`Bash

۴. Time

  • The “Time” field contains information about the current time in seconds.

  • This can have an impact when blocks are downloaded and how quickly they are integrated into the blockchain.

Diploma

The progress field -Debug -Protocols used by Bitcoin Core during IBD provide valuable information about the synchronization process. By analyzing these fields, developers and researchers can insight into the download of blocks from other knots in the network and how quickly they are integrated into the blockchain.
