Alkanes on-chain activity

Dec 29 – Jul 3 · 187 days · 96,349,790 transactions sampled · updated daily

Sampled data from our open-source OP_RETURN scanner. An exact full-chain engine is in the works. View the scanner and raw data on GitHub.

Daily Alkanes share

Tip: click a legend item to show/hide its line.

How much of Bitcoin's daily transaction volume is Alkanes, alongside how much of all Bitcoin transactions carry an OP_RETURN at all — Alkanes activity tracks the broader OP_RETURN trend closely.

Alkanes' share of OP_RETURN

Tip: click a legend item to show/hide its line.

Of every Bitcoin transaction that carries an OP_RETURN, 98.3% are Alkanes (last 30 days), and they account for 95.8% of all OP_RETURN data bytes. This is Alkanes' grip on OP_RETURN itself — independent of how many BTC tx use OP_RETURN at all.

Alkanes' share of block space (by weight)

This is the literal block space Alkanes occupy — transaction weight, the unit Bitcoin's block limit is actually denominated in (not byte counts, not transaction counts). Alkanes were 23.8% of all block weight over the period and 53.3% on the last measured day. This is the honest "how much of Bitcoin is Alkanes" answer: by weight they are still a minority of block space, far below their share of transaction count (most Alkanes tx are tiny DIESEL mints). Measured directly from each transaction's weight via a metashrew/alkanes-rs indexer.

Last day — share of OP_RETURN transactions
Alkanes 96%Other OP_RETURN 4%

How this is calculated. Last day = Jul 3 (Bitcoin blocks 956,389–956,532, 24 sampled). Of 57,100 transactions carrying an OP_RETURN that day, 54,579 were Alkanes → 95.6%. Share = Alkanes OP_RETURN tx ÷ all OP_RETURN tx. A transaction counts as Alkanes when one of its OP_RETURN outputs decodes as a Runestone whose protostone carries protocol_tag = 1.

DIESEL mints — share of all Bitcoin transactions

DIESEL, the genesis alkane, is minted directly on Bitcoin — this tracks how much of all Bitcoin transaction volume is DIESEL mints on their own, separate from other Alkanes activity.

UNCOMMON•GOODS mints that are DIESEL

UNCOMMON•GOODS (Rune 1:0) rides along on almost every DIESEL mint. Of all UNCOMMON•GOODS mints each day, the share that are also DIESEL climbed from 59.8% early on to 99.9% recently (76.8% over the whole period): when you see an UNCOMMON•GOODS mint today, it is almost always DIESEL "wearing Runes clothing." Detected as a runestone whose mint is Rune 1:0 on a DIESEL (cellpack 2:0 op 77) transaction.

OP_RETURN bytes (all time)
Alkanes 81.2%Runes 9.5%Other 9.2%

Of all OP_RETURN data written to Bitcoin over the tracked period, the share that is Alkanes, Runes, and everything else — measured in bytes, not transaction count.

OP_RETURN bytes per transaction

Tip: click a legend item to show/hide its line.

Alkanes' OP_RETURN payload is small and stable (~21.2 bytes/tx), while the rest of OP_RETURN traffic is larger and more volatile — Alkanes are byte-efficient on-chain. (Bytes = full OP_RETURN output script.)

Miner fee revenue

Daily revenue extrapolates the sampled blocks to a full day and adds the 3.125 BTC/block subsidy, converted to USD at that day's BTC price. The USD swings here are mostly the BTC price — the activity-driven part of miner income is the fees, shown next in BTC.

Miner fee revenue from fees (BTC) — Alkanes vs rest

Tip: click a legend item to show/hide its line.

The block subsidy is a fixed 3.125 BTC/block, so the part of miner income that grows with on-chain activity is the fees. This shows daily fees in BTC, split into what Alkanes transactions paid vs everything else — so you can see Alkanes' real contribution to miners' BTC earnings as Alkanes activity grows. Subsidy excluded.

Alkanes' share of miner fee revenue

By fee revenue — what miners actually earn from fees — Alkanes are 20.7% over the last 30 days (6.6% over the full tracked period), far below their share of transaction count, because most Alkanes tx are tiny DIESEL mints that pay little. All OP_RETURN traffic together pays 10.3% of fee revenue. (Subsidy excluded here; fees only.)

How it's calculated

The scanner reads every sampled Bitcoin block in the window and inspects each transaction's outputs. An output whose script starts with 6a is an OP_RETURN; one starting 6a5d is a Runestone.

It decodes the Runestone, and if any protostone carries protocol_tag = 1, the transaction is Alkanes. A DIESEL mint is the specific case where the cellpack targets 2:0 with opcode 77 (the genesis alkane) — today that's the vast majority of all Alkanes activity.

Share of transactions = matching tx ÷ all tx. Share of OP_RETURN bytes = Alkanes OP_RETURN bytes ÷ all OP_RETURN bytes. Shares are unaffected by sampling; each day rests on dozens of sampled blocks. Classification reuses the open-source alkanes-opreturn-decoder.

Glossary. OP_RETURN penetration: share of all BTC tx that carry an OP_RETURN. Alkanes (tx): share of all BTC tx that are Alkanes. Alkanes (bytes): share of OP_RETURN bytes that are Alkanes. Runes: OP_RETURN bytes that are Runestones but not Alkanes. Alkanes excl. DIESEL: Alkanes tx that aren't DIESEL mints — "real app" usage. DIESEL: mint of the genesis alkane (cellpack 2:0 op 77). Alkanes of OP_RETURN: of tx that carry an OP_RETURN, the share that are Alkanes (by tx and by bytes). Bytes per tx: average OP_RETURN script size per transaction in each bucket. Alkanes share of fee revenue: Alkanes fees ÷ total fees (subsidy excluded).
