SlovakBitcoin developers release proof-of-concept transaction writing 66kB image, challenging BIP-110 data limit proposal

SlovakBitcoin developer and RustBitcoin library maintainer Martin Habovštiak has released a proof of concept that writes a 66 kB TIFF image file to the Bitcoin blockchain through a single transaction without using OPRETURN, Taproot, or OPIF. The transaction can be publicly verified on-chain and can be decoded into a complete image file.

This experiment is seen as a direct challenge to the "anti-spam" soft fork proposal BIP-110, promoted by Luke Dashjr. BIP-110 is a successor to BIP-444, which aims to limit the scale of on-chain data writing, with some supporters arguing that such data storage practices deviate from Bitcoin's core positioning as a "currency."
