👉 The billing fluid is a concept in cryptocurrency transactions that represents the flow of funds from one party to another, essentially tracking the movement of tokens through a blockchain network. It's akin to a cash flow but operates on a digital ledger, where each transaction is recorded as a change in ownership of tokens. When a user sends tokens to another, it's a billing fluid transaction that updates the sender's balance and credits the recipient's balance, reflecting the transfer of assets on the blockchain. This fluidity allows for real-time tracking and verification of transactions, enhancing transparency and security in cryptocurrency exchanges.
