Bitcoin miners weigh BIP-110 after 66KB image test

What the 66 KB image demonstrates about BIP-110's limits

A Slovak developer, Martin Habovštiak, embedded a 66 KB TIFF image into Bitcoin in a single transaction, challenging core assumptions behind BIP-110, as reported by TodayOnChain. The test anchors a non-financial payload on-chain and frames a live question: do proposed limits meaningfully prevent arbitrary data embedding or merely change how, and where, it appears?

The same report notes he produced a BIP-110–compliant version that was larger, suggesting certain restrictions could unintentionally increase on-chain footprint. That outcome supports a policy concern often raised in protocol governance: narrow bans risk shifting usage to costlier or less transparent vectors rather than eliminating it.

Arbitrary data embedding without OPRETURN, Taproot, or OPIF

The demonstration reportedly avoided common carriers targeted by BIP-110, no OPRETURN, no Taproot, and no OPIF, while still fitting the 66 KB image into a single transaction, as reported by The Block. If restrictions only enumerate a subset of script paths or data pushes, motivated users may reroute payloads through remaining standard avenues.

The report also underscores a broader technical dynamic: when consensus rules constrain specific opcodes or encumbrances, embeddings can become a cat-and-mouse problem, potentially migrating to fields that are more resource-intensive for node operators. From a risk perspective, that migration can raise storage and bandwidth demands without resolving content concerns.

Critics of BIP-110 warn that content-based filtering at the consensus layer risks weakening Bitcoin’s neutrality and precedent discipline. “Filtering at consensus can set \"dangerous precedents\",” said Adam Back, CEO of Blockstream, as reported by Cointelegraph.

55% miner activation threshold, neutrality, and user safety

Debate over BIP-110’s proposed 55% miner activation threshold centers on whether such a low bar could fragment consensus or create user hazards if parts of the network diverge, according to Bitget. In soft-fork contexts, partial activation can introduce edge cases for transaction relay, wallet behavior, and perceived finality, which critics argue undermines user safety.

Separately, neutrality and censorship resistance remain core to Bitcoin’s design, and institutional commentary highlights that filtering “spam” at the protocol level can become a slippery standard, according to Mexc. The same analysis flags node-operator exposure, higher storage and bandwidth burdens and potential legal risks tied to hosting non-financial data, suggesting that any policy trade-off should be weighed against operational costs and jurisdictional uncertainty.
