  • \u00a0<\/span>New BIS research finds that estimates of Bitcoin\u2019s onchain transfer value can vary by up to sixfold depending on the methodology used.<\/span><\/li>\n
  • The discrepancy arises because Bitcoin\u2019s UTXO system generates \u201cchange\u201d outputs that are difficult to distinguish from genuine payments to third parties.<\/span><\/li>\n
  • Researchers must rely on heuristics to identify change, and these assumptions can dramatically alter reported transfer volumes.<\/span><\/li>\n
  • The BIS concludes that onchain data should be treated as an approximate guide to economic activity rather than a precise measurement.<\/span><\/li>\n<\/ul>\n<\/div>\n<\/div>\n

    Estimates of how much Bitcoin is transferred onchain can differ enormously depending on how the transactions are measured, according to a new working paper from the Bank for International Settlements (BIS).<\/p>\n

    The paper, BIS Working Paper No. 1377, was authored by Timothy Aerts, Ronald Heijmans, Jan Paulick and Violeta Vuletic and published in September 2026.<\/p>\n

    It highlights the difficulty of using raw blockchain data to measure economic activity. The BIS researchers examined different methods for estimating onchain transfer values and found that the choice of methodology alone can swing the results dramatically \u2013 in some cases, the most conservative estimate came in at roughly a sixth of the most permissive one.<\/p>\n

    The issue stems in part from Bitcoin\u2019s transaction structure. Bitcoin uses a system of unspent transaction outputs, or UTXOs, rather than account balances. When a user spends Bitcoin, the entire UTXO being used must be spent in the transaction. If the user spends less than the value of that UTXO, the remaining funds are typically sent back to the user as \u201cchange\u201d.<\/p>\n

    For instance, imagine someone holds a single UTXO worth 4 BTC and wants to pay a merchant 1.5 BTC. The resulting transaction would need to generate two outputs: 1.5 BTC going to the merchant, and the leftover 2.5 BTC returning to the original owner as change. Looking only at the raw blockchain data, both outputs look identical \u2013 as far as the ledger is concerned, 4 BTC total just moved \u2013 even though only 1.5 BTC actually changed hands.<\/p>\n

    Identifying which outputs represent change is therefore essential to estimating how much Bitcoin actually moves between different users. But the blockchain doesn\u2019t label this distinction. Wallets can, for example, route change to a brand-new address, making it just as anonymous-looking as a genuine payment to a third party.<\/p>\n

    No Accurate Measure of Economic Activity<\/h2>\n

    As a result, researchers have to lean on heuristics and assumptions to guess which outputs are changed. The BIS paper shows just how much this guesswork matters: depending on which heuristic is applied, estimates of onchain transfer volume can differ by a factor of roughly six.<\/p>\n

    The researchers frame this as symptomatic of a broader problem in analysing crypto activity. Onchain data is transparent and abundant, but that doesn\u2019t make it self-interpreting. Figures drawn from it carry real uncertainty and shouldn\u2019t be mistaken for a precise readout of genuine economic activity.<\/p>\n

    Notably, the findings don\u2019t relate to Bitcoin trading volumes on centralised exchanges. They\u2019re specifically about how much value is estimated to move directly on the blockchain itself \u2013 underscoring how much the interpretation of raw chain data can shape conclusions about network activity.<\/p>\n
