Alkanes on-chain activity

291,226,267 transactions sampled from Jan 20 to Sep 12

Based on sampled blocks, not a full-chain count. Everything is open source (MIT): alkanes-opreturn-decoder, alkanes-opreturn-scanner, and the daily data.

Daily Alkanes share
42.0%
This year

Click a legend item to hide or show it.

Share of all Bitcoin transactions that are Alkanes, next to the share that carry any OP_RETURN. The two move closely together.

Alkanes' share of OP_RETURN
75.1%transactions,77.5%bytes
This year

Over the last 30 days, Alkanes made up 97.1% of OP_RETURN transactions and 93.4% of OP_RETURN bytes.

Alkanes' share of block weight
27.8%
This year

Alkanes used 17.2% of block weight over the full period and 49.8% on the latest day. That's well below their share of transactions, since most are small DIESEL mints.

Alkanes' share of Bitcoin by four measures
42.0%by tx count,27.8%by weight,8.3%by fees,77.5%by bytes
This year

Alkanes rank high by transaction count because DIESEL mints are numerous and small. By block weight and fees, their share is much lower.

DIESEL mints as a share of all Bitcoin transactions
41.9%
This year

DIESEL mints only, not other Alkanes activity.

DIESEL mints per day
262,288
This year

Estimated mints per day, on a log scale. Minting took off in August and September 2025 and peaked near 551,346 a day.

UNCOMMON•GOODS mints that are DIESEL
77.8%
This year

UNCOMMON•GOODS (Rune 1:0) is minted alongside nearly every DIESEL mint. The share of UNCOMMON•GOODS mints that are also DIESEL rose from 0.0% in the first 30 days to 99.7% in the last 30 (76.3% overall).

UNCOMMON•GOODS mints per day
264,324DIESEL,44,038Independent Runes
This year

Split into mints that came with a DIESEL mint and independent ones. Raw counts from sampled blocks.

Alkanes vs Runes, share of OP_RETURN bytes
77.5%Alkanes,11.3%Runes (non-Alkanes)
This year

Alkanes have overtaken non-Alkanes Runes in OP_RETURN bytes.

Alkanes vs Runes, OP_RETURN bytes per day
5.6MBAlkanes,365.6KBRunes (non-Alkanes)
This year

Estimated bytes per day, on a log scale.

OP_RETURN byte composition over time
77.5%Alkanes,11.3%Runes (non-Alkanes),11.1%Other
This year

Daily split of OP_RETURN bytes between Alkanes, other Runes, and everything else.

Alkanes vs Runes, share of Runestone transactions
77.5%Alkanes,22.5%Runes (non-Alkanes)
This year

Runes led when DIESEL launched. Alkanes are now the large majority of Runestone transactions.

Alkanes vs Runes, Runestone transactions per day
264,392Alkanes,44,540Runes (non-Alkanes)
This year

Estimated transactions per day, on a log scale.

OP_RETURN bytes since DIESEL genesis
Alkanes 77.9%Other Runes 9.5%Non-Runes OP_RETURN 12.6%

All OP_RETURN data since block 880,000 (Jan 20, 2025), by bytes. Alkanes sit inside Runestones, so Alkanes plus Other Runes make up all Runestones. The Alkanes share is a lower bound because Runestone envelope bytes count as Other Runes.

Daily miner fees (BTC)
0.242 BTCAlkanes fees,2.596 BTCOther fees
This year

Fees only, split between Alkanes transactions and everything else. Unlike the fixed 3.125 BTC subsidy, fees grow with on-chain activity.

Alkanes' share of miner fee revenue
8.3%
This year

Alkanes paid 12.1% of miner fees over the last 30 days (4.6% over the full period). All OP_RETURN transactions together paid 16.0% (9.2% over the full period).

How it's calculated

Each day the scanner reads a sample of Bitcoin blocks and checks every transaction output. An output script starting with 6a is an OP_RETURN, and one starting with 6a5d is a Runestone.

A transaction counts as Alkanes when its Runestone holds a protostone with protocol_tag = 1. DIESEL mints, which make up most Alkanes activity today, are the ones whose cellpack targets 2:0 with opcode 77.

Shares are ratios within the sample, so sampling doesn't skew them. Each day draws on dozens of blocks, and daily totals are estimated by scaling the sample up to a full 144-block day. Classification uses the open-source alkanes-opreturn-decoder, and block weight comes from a metashrew/alkanes-rs indexer.

OP_RETURN penetration
Share of all Bitcoin transactions with an OP_RETURN output.
Runes (non-Alkanes)
Runestones without an Alkanes protostone.
DIESEL mint
A call to the genesis alkane (cellpack 2:0, opcode 77).
Block weight
The unit Bitcoin's block size limit is measured in.
Fee share
Fees only. The 3.125 BTC block subsidy is excluded.
