Methodology

Balance

Current address balance is calculated from unspent transaction outputs (UTXOs):

SUM(amount) WHERE spent = 0 GROUP BY address

The displayed balance therefore represents the current unspent amount indexed by the local Qubitcoin node.

Received and Sent

Received values are derived from recorded transaction outputs. Sent values are derived from recorded transaction inputs.

Transaction flows

The Bubble Map can reconstruct probable flows between addresses by proportionally relating transaction inputs to transaction outputs. This is a visualization heuristic rather than proof of ownership, control or intent.
