Implementing blockchain-based token attribution with reduced computational complexity

A system comprising:

• a memory;
• and
• a processing device, operatively coupled to a memory, to perform operations comprising:
• receiving a transfer request defining a transfer amount of tokens to be transferred from sender associated with a first digital wallet to a receiver associated with a second digital wallet, wherein the sender has a total token balance comprising an attributed token balance of attributed tokens having a first attribution property identifying a corresponding token issuer, and a float token balance of float tokens, wherein the attribution token balance and the float token balance are maintained within a token contract, and wherein the receiver is assigned with a designated attribution property;
• and
• causing a transfer function of the token contract to be executed to transfer a set of tokens from the sender to the receiver, wherein the set of tokens is determined based on a transaction payload comprising at least one of:
• a number of attributed tokens debited from the attributed token balance or a number of float tokens debited from the float token balance.
