Slovak Bitcoin developer Martin Habovštiak wrote a 66kB TIFF image file into the Bitcoin blockchain through a single transaction, challenging Luke Dashjr's BIP-110 proposal, which aims to limit the scale of on-chain data writes. This experiment can be verified on-chain and the image can be fully decoded.

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

This experiment is seen as a direct challenge to Luke Dashjr’s proposed “anti-spam” soft fork BIP-110. BIP-110, formerly known as BIP-444, aims to limit on-chain data storage, with some supporters believing such data storage behaviors deviate from Bitcoin’s core role as a “currency.” (The Block)
