understanding the message “Sendcmpct” in Bitcoin
When a node from Bitcoin Testne3 (also known as “Testnet”) initiates the transaction and sends the message “SendcmpCC” to other nodes, it sends a comprehensive data structure to transmit important information about transactions. In this article, we will divide what each field in the message “Sendcmpct” usually represents.
Message structure Sendcmpcta
The SENDCMPCT 'report is part of the Bitcoin protocol used for testing transactions3. The structure consists of 30 fields that are divided into two main parts: "heads and data".
* Title : This section contains a transaction metadata including:
*Vsize: the number of bytes allocated to the transaction head.
* "Introduction", "Exit" and "Timestamp": time stamps for each part of the transaction. In this case, there are two time stamps received and two outputs, which suggests that these transactions were initiated by the sender (node A) and by the receiver (Node B).
* Data : This section contains real data sent between knots to the test3.
Decoding MessageSendcmpct
Let's examine the first pair of bytes from the message "Sendcmpct" that you received:[11, 17, 9, 7, 115, 101, 110, 100, 99]. We need to understand its structure to decode this report.
Assuming that the data are formatted correctly and do not contain bytes, we can conclude that each field in the "Data" section represents a specific value. Here's what we know about the first few fields:
- It seems that the first two bytes (11
," 17 ") are a pair of field indices (probably representing the values for time stamps" receiving "received" and "output").
- It seems that the next four bytes (9
,7,115 ‘,101') represent the complete value.
- The next six bytes (110″,
100", "99") can be another pair of indices or a single value.
Interpretation of field values
It is difficult to provide specific meanings for each area without an additional context. However, we can make some educated estimates based on normal procedures for the proposal of the Bitcoin Protocol:
- Index pairs (11 and 17) could represent values such as:
*Inbound_timstampa: a value indicating the time stamp at which the transaction started.
*Outbound_timestampa: a time stamp value to which the transaction was sent or received by knot B.
- The entire value number (115
,101) may be a specific constant related to Bitcoins, for example:
*Value: did not sign a 32-bit integer representing an important value in the Bitcoin protocol (for example, the hash coinbase).
* Size: it signed an integer that indicates the size of this field.
- The last two bytes (
110", "100") can be indexes or values related to other aspects such as:
*Index: an index in the field of specific value related to bitcoins (for example, transaction type).
* Value: a value indicating the specific construction of the Bitcoins protocol.
If you want to decode the entire message and understand its content, you need to consult the Bitcoin Testte3 documentation and network rules. The message "Sendcmpct" is only one aspect of the total Bitcoin protocol, and its structure can vary when new functions and updates are implemented.
Recommendations for further research
- Refer to a Bitcoin Testet3 documentation3: <
- Please check the Rules and Network Specifications forSendcmpct`
- Review the principles and standards of Bitcoin Protocol design
By understanding the “Sendcmpct” structure, you will be better equipped to interpret its content and to make the knowledge of your own rust code.
