Bitcoin's network is busier than at almost any point in its history — but the transactions driving that activity are not people moving money. Microtransactions below 0.01 BTC now account for approximately 80% of all daily Bitcoin transactions, pushing CryptoQuant's Bitcoin Network Activity Index into positive territory for the first time since 2024, according to a Thursday report by CryptoQuant head of research Julio Moreno.
The index is now just 7% below the all-time high recorded in September 2024 — meaning Bitcoin's blockchain is operating near peak capacity in terms of transaction volume, even as price action remains muted and institutional ETF flows have been negative for weeks.
How microtransactions went from 44% to 80%
Transactions below 0.01 BTC represented approximately 44% of all daily Bitcoin transactions in 2023. Their share has nearly doubled since then — fueled largely by Ordinals, Runes, BRC-20 tokens, and other data-inscription protocols that generate high volumes of dust-value transactions, some as low as 546 satoshis — the minimum value required for a transaction to be considered non-dust by the network.
The growth reflects the expanding use of Bitcoin's blockchain as a data layer rather than purely a value transfer mechanism. "The economic value of these transactions is, however, disproportionately small," Moreno wrote — a precise observation that carries an important implication: near-record network activity is not indicating near-record economic demand for Bitcoin as money. It is indicating near-record demand for Bitcoin's blockchain as a censorship-resistant data storage medium.
OP_RETURN: near-record usage and an ongoing community debate
The primary technical mechanism behind the surge is OP_RETURN — a Bitcoin script opcode that allows data to be embedded directly on the blockchain without creating spendable outputs. OP_RETURN usage has climbed to near-record levels in 2026, following the removal of an 80-byte relay limit by Bitcoin Core developers in 2025 — a change that split the Bitcoin developer community. Critics argued the removal would accelerate the use of Bitcoin's blockchain for non-financial data storage, effectively subsidising inscription activity at the expense of ordinary financial transactions competing for block space.
The 2025 debate appears to have been predictive. With OP_RETURN now capable of embedding up to 100,000 bytes of data on-chain without creating spendable outputs, it has become the standard mechanism for Bitcoin data-layer protocols — enabling Runes, Ordinals, BRC-20 tokens, and data-timestamping services to operate efficiently at scale.
Mempool congestion: highest since February 2025
The surge in microtransactions has pushed Bitcoin's mempool — the holding area for unconfirmed transactions awaiting inclusion in a block — to approximately 128,000 transactions, its highest count since February 2025. Mempool congestion of this scale creates a competitive fee environment: users who need their transactions confirmed quickly must bid higher fees, while inscription-driven dust transactions add volume that competes for the same finite block space.
Moreno flagged the structural risk directly: sustained growth in non-financial activity could "increase block space competition and raise fees for economic transactions" — meaning the very users who want to use Bitcoin as money may face higher costs as a direct consequence of inscription protocol growth. This tension between Bitcoin's utility as a value transfer network and its growing role as a data layer is one of the most active debates in the Bitcoin development community and has no consensus resolution.
Historical context: Ordinals 2023 and Runes 2024
The current congestion has precedent, though it has not yet reached prior peaks. Transaction backlogs surged in 2023 as Ordinals and BRC-20 activity competed with ordinary transfers for block space — a period that introduced the inscription debate to mainstream Bitcoin discourse. Another significant spike emerged in late 2024 following the launch of the Runes protocol, which offered a more efficient standard for fungible token issuance on Bitcoin than BRC-20.
The current surge differs from those episodes in one important way: it is more sustained and structurally embedded rather than concentrated in short boom periods. With OP_RETURN limits removed and multiple data protocols now operating simultaneously — Runes, Ordinals, BRC-20, and data-timestamping services all generating microtransaction volume — the network congestion appears less likely to resolve naturally when a specific protocol's novelty fades.
The positive signal within the noise
Despite the economic activity concern Moreno raised, the Network Activity Index turning positive for the first time since 2024 is not entirely without positive implications for Bitcoin's broader ecosystem. Developer activity, data protocol usage, and user experimentation with Bitcoin's programmability have historically preceded periods of increased mainstream interest and adoption. The Ordinals boom of 2023 introduced a new generation of developers to Bitcoin's scripting capabilities. Runes brought fungible token issuance to Bitcoin in ways that competed directly with Ethereum and Solana's token ecosystems.
Whether the current microtransaction surge represents the early stages of a similar adoption wave — or simply inscription protocol activity that inflates network statistics without corresponding economic value creation — is the question that Moreno's report raises but does not fully resolve. For investors focused on Bitcoin's price recovery and on the demand-side signals that CryptoQuant has identified as necessary for a confirmed market turn, network activity driven by 546-satoshi inscriptions is a different signal than network activity driven by large-value economic transfers — and distinguishing between the two remains essential context for interpreting Bitcoin's on-chain health during the current correction.
