Bitcoin Core Sync Progress Field Debug Logs

Bitcoin Core is a software for managing Bitcoin wallets and transactions. One of its key functions is to synchronize with other Bitcoin nodes to keep the data on the blockchain up to date. This process involves downloading new blocks from other nodes on the network, which can be difficult due to the complexity of the blockchain.

Calculating Progress Field Debug Logs

The progress field debug logs used by Bitcoin Core during IBD (initial block mining) typically contain information about the synchronization process. Here are some key elements that contribute to this progress:

1. Best Hash

• The best field in the debug.log file refers to the hash of the best block found on the network so far.

• Calculated based on the latest available data, which includes the block number, hash, and previous best hash of the block.

2. New best hash

• The new_best field indicates that a new best block has been found.

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

3. Block number and hash

• The block_number and hash fields provide information about the block being mined.

• These values ​​are used to calculate best_hash.

4. Previous best hash of the block

• The previous_best_hash field indicates which previous block was the best and how long ago.

Additional factors

In addition to these fields, other factors may be taken into account when calculating Bitcoin Core sync progress during IBD. Some of them include:

1. Block difficulty

• The block_difficulty field contains information about the current difficulty level of the block.

• This can affect whether new blocks are downloaded and how quickly they are included in the blockchain.

2. Block Difficulty Factor

• The block_difficulty_ratio field contains information about the ratio of block difficulty to network difficulty.

• This can affect whether blocks are mined and how quickly they are added to the blockchain.

3. Block Reward

• The block_reward field contains information about the current reward for mining a block.

• This can affect whether blocks are mined and how quickly they are added to the blockchain.

4. Time

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

• This can affect when blocks are downloaded and how quickly they are included in the blockchain.

Appendix

The debug logs in the progress field used by Bitcoin Core during IBD provide valuable information about the synchronization process. By analyzing these fields, developers and researchers can gain insight into how blocks are downloaded from other nodes on the network and how quickly they are included in the blockchain.
