Sixfold Error in Bitcoin Transfer Estimates Revealed by BIS Study
A recent Bank for International Settlements (BIS) working paper found that estimates of Bitcoin transfer values can differ by as much as six times depending on how they are measured. The study, published on September 15, used multiple approaches to calculate the value transferred in Bitcoin transactions and found significant discrepancies between them.
The researchers identified three structural sources of measurement divergence: transaction aggregation, smart-contract programmability, and comparisons of activity across blockchains. They also highlighted how contracts and stablecoins complicate comparisons by making it harder to identify economically meaningful activity.
The study analyzed 13 million active contracts and found that trading activity was highly concentrated and centered around stablecoins. The authors noted that the same stablecoin had different economic uses depending on the blockchain, with Ethereum users more likely to use it for smart-contract interactions and Tron users holding it outside of smart contracts.
The researchers concluded that on-chain indicators should be read as noisy approximations rather than direct measures of economic activity. They proposed granular, data-bounded estimates that make assumptions explicit and use technical classification and disaggregation to connect ledger events with economic meaning.
