Understand the Bitcoin Locktime transaction
As a Bitcoin user, understanding the nuances of the transaction blocking time is crucial to understand how transactions in the block chain are verified and process. In this article, we will deepen the details of how a given transaction was satisfied with its relative blocking time.
TRANSACTIONS DISGLOSE
Let’s analyze the transaction provided: 3C1C9FB9D6B215EFDEDB5CAF6A951A9E6C6C1E3DE6E5674F646C63E94667497. This transaction involves three entries, which we will refer to as «1» and «2». The output of the first entry is labeled as «3», while the second entry is known as «32».
op_pushbytes
The first lines of the transaction are op_pushbytes_3 Fa0140, followed byop_csv. These commands indicate that we are about to press a byte chain (the 0x4001FA value) and then calculate the sum of verification (op_csv) for it.
op_drop
Next, the transaction performs an op_drop command, which indicates that the sum of previously calculated verification is being eliminated. This is done so that subsequent calculations can be performed without recovering the sum of verification.
Relative satisfaction of lock time
Now, let’s focus on satisfying the relative blocking time for this transaction. Relative blocking time refers to the time interval between two consecutive transactions that share a common entry. In other words, if transaction A has an entry with the X value and transaction B shares the same input, then the relative blocking time of transaction B would be the difference between its input values.
For our given transaction:
- Input 1 (with the 0x4001FA value) is shared by both transactions.
- Output of transaction A is output 3, while the output of transaction B is labeled as «32».
To satisfy the relative blocking time for this transaction, we must ensure that the difference between the input values does not exceed a certain threshold. In the Bitcoin context, the default value for input validation is established in ` This case, transaction a).
However, since both entries have the same value (0x4001FA), and we have already eliminated the sum of verification, it is unlikely that the transaction will be validated. In practice, Bitcoin uses a more robust validation mechanism that involves multiple checks, including the ‘op_checkmintcommand.
Conclusion
In summary, to satisfy the relative blocking time for this specific transaction, the input values must coincide exactly between consecutive transactions that share a common entry. Since both entries have the same value (0x4001FA`), it is unlikely that the difference in the input values will be significant enough to activate the validation verifications. However, this provides information on how Bitcoin blocking mechanisms work and highlights the importance of carefully examining transactions inputs when verifying their relative blocking time.
