How Blockchain Transactions Work: From Initiation to Immutable Confirmation (Part 2)

The preceding screenshot visually shows how the transaction flowed on the network from origin (sender) to receivers on the right-hand side.

A summary view of various attributes of the transaction is shown here: Snapshot of the transaction taken from Blockchain.info Looking at the preceding screenshot there are a number of fields that contain various values.

From Initiation to Immutable Confirmation (Part 2)

Important fields are listed here with their purpose and explanation: Size: This is the size of the transaction in bytes.

Weight: This is the new metric given for block and transaction size since the introduction of Segregated Witness (SegWit) version of Bitcoin.

Received Time: This is the time when the transaction is received.

Included In Blocks: This shows the block number on the blockchain in which the transaction is included.

Confirmations: This is the number of confirmations by miners for this transaction.

Total Input: This is the number of total inputs in the transaction.

Why This Matters for Blockchain Technology

Total Output: This is the number of total outputs in the transaction.

Fee per byte: This field represents the total fee divided by the number of bytes in a transaction.

Fee per weight unit: For legacy transaction it is calculated using total number of bytes * 4.

For SegWit transactions it is calculated by combining SegWit marker, flag, and witness field as one weight unit and each byte of other fields as four weight units.

Conclusion

Transaction flow visualization (Blockchain.info) represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.

Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
