Why Is the Fee Calculated Based on Transaction Size (Bytes) Rather than Value?
The transaction fee is calculated based on size (bytes or vbytes) because the cost to the network is related to the consumption of the scarce resource: block space. Block space is measured in data size, not monetary value.
A transaction transferring a small amount of cryptocurrency takes up the same amount of block space as a transaction transferring a large amount, provided their data structures are identical. Charging by size ensures that the fee accurately reflects the resource usage and maintains the economic incentive for miners to prioritize based on efficiency.

Wallet Software
Function ⎊ Wallet Software serves as the essential interface for managing a user's digital currency holdings, primarily by securely storing and controlling the private keys necessary for authorizing transactions.
Inputs and Outputs
Transaction ⎊ Inputs and outputs are the fundamental components of a blockchain transaction, particularly in UTXO models like Bitcoin.
Block Space
Capacity ⎊ This term quantifies the finite data volume available within each successfully mined block, representing a scarce resource for transaction inclusion.
Resource Usage
Allocation ⎊ Resource utilization within cryptocurrency, options, and derivatives necessitates a rigorous allocation framework, particularly when considering sustainability implications.
Transaction Size
Scale ⎊ Transaction size, within cryptocurrency, options, and derivatives, fundamentally dictates participation thresholds and systemic risk exposure; it represents the nominal value of an executed trade or a portfolio’s aggregated holdings, influencing liquidity provision and market impact.
