Alkanes DIESEL metaprotocol dominates Bitcoin transactions over summer 2026

The Alkanes DIESEL metaprotocol, maintained by SUBFROST, dominated Bitcoin transactions over the summer of 2026, accounting for 61.1% of all transactions (59.9 million) between June 23 and September 20. Despite utilizing 94.2% of OP_RETURN bytes, this activity was initially misattributed to the Runes protocol by major outlets like CoinDesk. Alkanes runs on top of Runes using WebAssembly without altering Bitcoin consensus, supported by a highly active Asia Pacific user base.

Alkanes transaction metrics

• ▪Renaud Cuny, author of Bitcoin Block Space Weekly, independently calculated that Alkanes protostones accounted for 91% of Bitcoin OP_RETURN outputs over a 60-day window ending in September 2026.
• ▪According to data from SUBFROST, Alkanes transactions accounted for 61.1% of all Bitcoin transactions, totaling approximately 59.9 million transactions, between June 23, 2026, and September 20, 2026.
• ▪SUBFROST reported that 99.7% of UNCOMMON•GOODS Runes mints between June 23, 2026, and September 20, 2026, were DIESEL mints, which represent almost all Alkanes activity.
• ▪According to SUBFROST, Alkanes transactions utilized 40.3% of Bitcoin block space by weight, 94.2% of OP_RETURN bytes, and 13.4% of transaction-fee revenue between June 23, 2026, and September 20, 2026.

June 2026 network activity

• ▪In June 2026, CryptoQuant, CoinDesk, and Bitcoin Magazine reported record daily Bitcoin transactions exceeding 800,000 and 820,000, driven by over 600,000 runestones, attributing the surge to Runes, Ordinals, and BRC-20 without mentioning wrapped Alkanes activity.
• ▪In June 2026, CryptoQuant reported that Bitcoin network activity had reached its highest level since late 2024.

Technical design of Alkanes

• ▪Alkanes executes contract function calls inside Runes-format runestones using a separate indexer called Metashrew, while Bitcoin full nodes confirm transactions without validating Alkanes balances.
• ▪Alkanes is a Bitcoin metaprotocol built on top of the Runes protocol that executes WebAssembly contract code deployed in witness data without altering Bitcoin consensus or operating as a sidechain.

Alkanes protocol maintenance

• ▪In January 2026, Oyl Corp announced that it was winding down its operations.
• ▪Alkanes launched on January 20, 2025, with the deployment of the DIESEL contract, and protocol maintenance transitioned from Oyl Corp to SUBFROST in January 2026.

Alkanes adoption in Asia Pacific

• ▪The Alkanes user community is predominantly located in the Asia Pacific region, with a significant portion of discussions on X originating from Chinese-speaking users referencing the Hong Kong-based UniSat wallet.
• ▪To support its user base, SUBFROST provides Chinese-language documentation, a Chinese metrics page, an official Chinese Telegram channel for DIESEL, and has hosted workshops and presentations in China and Hong Kong.

Debatable claims

• ▪Alkanes transactions do more harm than good to the Bitcoin network
• ▪Bitcoin block space should be reserved exclusively for monetary transactions
• ▪Western crypto media overlook significant blockchain activity originating in the Asia-Pacific region
• ▪Relying on off-chain indexers for Alkanes transactions compromises Bitcoin's security model
